finally a 'Car Stereo man' who can understand clearly and actually solve a problem
Best troubleshooting checklist video I've seen. Cant believe this doesn't have soooooooo many more views. Very informative. Much appreciated
Definitely the best video on UA-cam on how to check if the wiring to your amp is correct, I recommend also watching his video on, “How To Troubleshoot Your Subwoofers”. These videos are very informative and helped me when installing my two subwoofers and amp.
Yeah i want to see that video on protect mode and how to get it out of protect when you know you fixed the issues with everything else. That seems to be the hardest thing to figure out for most people.
You sir deserve a medal. That is by far the best explanation over the entire net. Thank you so much this will most definitely help me locate my issue
Very well explained! Thank you for your informative videos! Sundown or die!
Step by step I’ve followed your videos and today I established the speaker wires from amp had been cut. Also cut at the speaker end. No idea why you would do that but leave everything else connected. New wires installed and new rca cables and my 2 x subs are working a treat. Thank you so much for your vids they are very much appreciated 👍🏻
Exactly how I trouble shoot lol I recently had my saz3500 v1 let go and it was a smoking mess . It went into protect and I turned off the radio and let it sit for a minute, then turned it back on and it started popping and smoking . I very quickly pulled the power wire out . After that I took the amp out and opened it up. A bunch of power supply fets let go .looking at that burnt up mess broke my hart. I had this amp a long time and love it , but I cant afford to rebuild or replace it due to being on a tight budget. But in all I love your products and videos . Great job . Keep it up.
Good job u really explain what to check when ur system acts up thanx 👍🏼
Damn man thats the best explanation yet!! Hands down.. great job bro!!
Awesome video as always!
Great info here for troubleshooting.
👍🏻😎👍🏻
Subbed for a while now. I've watched videos multiple times mainly because it's advice I didn't think of or I'm using it as an instruction
Good lesson on using the DMM. Learned a few ways to know if power was going thru wires.
Thank you broseph** good to hear everything
Good info!Veryyyy good info and we'll explained great job my friend!
I have a Sundown SIA-3500 amp on 2 Sundown X-10 subs. This has been a great setup. It was working perfectly, I parked the car overnight, the next day the amp would scroll through its test sequence twice and then go into protect mode. It's got 14v at power, the ground is good, and it has 14v at the remote wire. It stays in protect mode with everything disconnected except power, Ground, and remote. Any advice?
Back on the day I can’t even tell you how many times I would find agu fuses that the element would come undone under the cap where you can’t see. I saw this on name brand and cheap agu fuses, was super happy when my wiring supplier JL Troy started shipping mini anl fuses
Awesome vid! Thanks!
Best troubleshooting video 👌👌👌
If you had no idea what to look for or how to look for it, this was definitely informative.
What's up Derrick excellent good video topic of choice for discussion
Didn't watch the whole vid, but good for others that don't know. good job sundown
Thanks for the advice 🎉🎉 mine would cut out when I start to drive it was the remote cable
Very informative video! Any update on the video about troubleshooting an amp in protect with nothing but power ground and remote?
My worst fear:
No Bass
This is a great video
Do you have a video for short term protection causes and possible remedies ? Love all my Sundown Audio gear and always smile when ppl are droppin jaws at a single 10" hittin lows that they swear are a couple of 15's , lol
i wanna know how you figured out load sharing on those psu 's if they aren't the meanwells with load sharing built in. i know it's possible because i've seen the ham guys build amps out of them but never found a video covering it.
Pioneer head units:
Check the Sub Woofer selection.. If it's not on on REV or NOR the signal is not sent to the amp. 😉👍
Great video watched the whole thing and I'm afraid my amp blew, I'm not getting any power or lights at all but all my fuses are still good, I'm starting to think the enclosure my amp is installed in trapped hot air and it over heated internally...
My subs will go quiet but almost always come right back after a few seconds. Amp always has power, Ive checked connections 50 times over. Some times it just goes quiet and wont come back until I shut the truck off and back on. Could happen right at the start of the drive or the middle or it could go a whole day without doing it. Im fairly lost at this point aside from pulling the amp to check for internal damage. Just doesn't fully line up since its so intermittent. I've had this amp/sub combo since 2014 issue free. Now im dealing with this intermittent sub cut out for 2 ish months now.
To check to see if the sub is blown check impedance at the amp.
Phenomenal video brother!! What happens when the amp is not in protect but the music cuts out and sometimes wiggling the RCA wires that are firmly seated brings signal back in?
Also, is there a video on how to troubleshoot why an amp is in protect after grounding issues caused the amp to go into protect and then the amp was removed from the car for weeks without any wires attached but it remains in protect when it had only power put back on it and no speaker/RCA wires connected?
Where can i get the power/ground input terminal for a sax 100.4 needs to be through hole
Blinking protect light, short blink of the blue and back to blinking red. A friends sfb 1500.1d. Any feedback?
i got a alpine amp pdx 600 and it says its 2 ohms but whenever i wire it to 2 itll go right into protect mode and stay in protect until i turn it completely off
What do you do when you have power going to the amp but no lights on the amp turn on?. My amp was working this morning at lunch time I unhooked my external crossover to hook up a new better one i got everything hooked up and since then I've had nothing.
I got a question. my Amp stopped working so I got the handy power meter out as you suggested! so this is on the amp itself ground to positive I get 8.63 volts with ac on. ok from ground to Rem I get 10.68 volts what could be the issue still scratching my head.
Still wish you guys would go to hex set screws...the little things.
I just bought a sfb 3000d and it says it rated for 1ohm and what do you know had it set by shop and it still blowed trying to get it repaired or replaced.
So my amp, it’s new, been working good for like a month now, however it’s been randomly shutting off for a second or two and turning back on as my bass knob is flashing when it’s doing that, could it be my voltage is to low and it waits till it charges again?
This vid reminded me of what happened to me about 2 yrs ago. I was jamming on my way home from work and the subs just cut off. Looked in my mirror and seen smoke! Thought my amp nuked. Took it out ad it was literally 1 week out of warranty. Took the back plate off and nothing was wrong!? Turns out i nuked the speaker wire to the subs.. And it was pretty big wire...Melted through the rear carpet....
Bought a sfb1500d pushing 2 10" solobaric l7. On one side it starts clipping after a certain volume but on the other sub it plays perfectly. Swapped back to my old amp and both subs hit perfectly no clipping nose. What could be causing this with the amp?
Why did you cut out the part where it could’ve been the amplifier in to protect with nothing hooked up
Is there a video of if resetting the stereo turns the amp back on out of protection
Good info I've got a issue I've got a 4 channel 360.4 kicker to run my front and rear replacement speakers capable of 65 watts each when I turn gain up on amp 1 and 2 the music cuts out goes into protect mode so I am forced to barely turn both gains up just a hair and turn volume up then it don't go into protection mode any ideas why I can't get the higher volume I want???
So checking the voice coil and the impedance is all over the place.. zv5 d2 one side reads 1.8 and the other is 1.8 to 6 ohms sitting still...it hard and then it sounded weird from then on
Would a bad loc cause an issue where at somewhat higher volume, the amp kicks off, then it will come back on?
Yep just put a sub and amp/capacitor in my truck and have power everywhere but no sound from sub. Eliminated sub and enclosure. Need to check for signal on rca’s and from speaker terminals
I have a soundstream TXP1 6000.1 monoblock amp running 2 soundstream T5 tarantula 12’s wired down to 1 ohm. Everything was working fine and then the subs cut off. When I looked at the amp I noticed the power light was still on, but the clip light is also lit. The protect light is not on. The clip light stays on even when I unhook the speaker wires. What could be the problem?
My mono block should put out 1250 watts on 2 ohm and I do get sound from my subwoofer but It's barely anything, can't hear it while driving. I measured AC volts from the speaker outputs and it's only putting out 10 volts at MAX gain! Is my amp blown?
Hey derrick I have a question. I have 4 4500 watt subs but only 1 ns1v2 so I need another amp. Can I push 2 subs on my ns1 and the other 2 subs on a salt 8k or do I need matching amps? I want to buy a salt 8k instead of a second ns1 but im not sure if the amps have to be matching. Obviously id tune the salt 8k down to keep all 4 subs seeing roughly the same power. will that work?
When will u b dynoing the salt 6-4ks
@sundownunofficial you think you can do a video on how to wire or the proper stuff needed for a agm starting battery for primary and a lithium batteries for secondary?
We need this video fast. I think I just fried my 3500.1 skar from running at 11.89 V with an AGM primary and Down4Sound lithium
So my bass was always good. My alternator went out, I replaced it and now when my bass hit, my amp goes to protect mode. Could my alternator wire be loose? I noticed the alternator wire to the battery melted a lil bit, can that be a problem as well? Could my amp be bad?
So my SCV-2000D took a dump on me after almost 5 years. I have voltage, ground, remote. I have voltage from my RCA's from my LC2i. The blue power light is on. But I have no output to the subs. It was working good after I replaced the LC2i with a new one and then it would work some times and then sometimes it wouldn't. Now I get nothing and I did all the diagnostics. Is there a common fix for this issue? Is it the mosfets or possibly a capacitor? I am also interested to know if you happen to have an idea of what it would cost to have it repaired? I haven't removed the amp to open it or anything. I love the amp and I am running 2 SA-12's. I just ordered an Apex CAB 22 to replace it for now.
Did they ever do the protect video.?
How much amperage is your ac dc converter in that video
Thanks tomorrow I'm gonna see what's up with my tweeters. Gonna check the ac volt output on the amp if I see it works then it's the speaker wire. Cause I put the tweets on my other amp and they seem to work
This is glorious, been searching for "amplifier troubleshooting flowchart" for a while now, and I think this has helped. You ever tried - Giyathan Bewildering Gratification - (search on google ) ? It is an awesome exclusive product for discovering how to repair your electronic items like a wizard minus the normal expense. Ive heard some unbelievable things about it and my work buddy got excellent results with it.
What if there is no reading at the speaker output channels at all?
Rca voltage reads 22volts DC at any volume on sub out? What's wrong?
Hoping for a video on short term protect mode problems/solutions. My sub bumps, and has been sturdy for a year, but when I crank the volume now the amp will put itself into protect mode. This is happening at volumes far lower than I used to be able to play songs at.
@noahmx9051 , did you ever figure out the issue you was having ? Mine is doing the same
Mine amplifier act up today it's a 2000.1d sundown running on 1 ohm gain not even half way, amplifier started smoking and protect light and clipping light stays on even when I disconnect RCA on in put blue light keeps flashing on and off question is did the amp blow ? Keep in mind the protect light clipping light stays on
What about if there’s no AC voltage output from the amplifier??
Anyone know why my remote cable isn’t turning off an amp when I turn off the car. Someone told me run it high to low instead did that everything works fine it just won’t turn off so for now I have the remote cable cut and just twist it when I get in. I tried hooking it up with the ignition and anything else you can think of.
HELLA YEAH MY BROTHA THAT SHIZNIT WAS AMAZINGLY AWESOME 💯 PERCENT 👍🏽👍🏽 OMG I WOULD ALWAYS HAVE TO TAKE MY CAR'S OR TRUCKS BACK TO THE PLACE I HAD THEM HOOKED UP AND YEAH THEY DEFINITELY GOT ME MANY TIMES FOR 2 AND 3 HUNDRED HERE AND THERE THEY PLAYED THE SHIZNIT OUT OF ME BUT SOMETIMES U GOTTA LEARN THE HARD WAY BUT THANK'S TO U GUYS AND UR VIDEO'S SO MANY PEOPLE LEARN SO MUCH AND ESPECIALLY ME SO I'M PERSONALLY SAYING THANK YOU FOR ALL YOUR VIDEOS AND ALL YOUR EQUIPMENT TOP OF THE LINE I SUBSCRIBE TO ANYTHING SUNDOWN AUDIO BRO I GIVE THIS VIDEO A 💯 PERCENT 👍🏽👍🏽 OK SORRY FOR RAMBLING ON (🇵🇷✌🏽💪🏽🔈✌🏽💪🏽🔉✌🏽💪🏽🔊🇵🇷)
What if I have output from the amp but it is not as loud as it should be? Example: was playing normal and went in to store came out and now it is not loud as normal. Sub reads 2ohm on each coil.
@unofficialaudio or anyone with knowledge , here’s one problem u haven’t mentioned that I’m going thru. My amp turns on works good and recently just recently itll lose power , if I hit the amplifier lightly the power will cut back on , what would I recommend the issue would be that I’m going thru?
Hello boss. you got everything in step that's happened to some people. like me. that SECOND FROM last part, rite before RCA checking power. got sign of music playing, but remember RCA is taking over the SUBWOOF. so plug in rca SUBWOOF is GOES OFF. WHY IS THAT ? help if you can please
Every time I turn my amp gain remote past a quarter turn it puts the amp into safe mode but if I turn it back to a quarter turn or less the amount is now working again. What do you think is wrong?
Ok I was unhooking my speaker and the car was on and when I took out the positive the wire fell and hit the positive on my second battery and aferg that it made my amp make a weird sound in the speacker I put it on another amp it's fine so I know speacker is good idk what the problem. Is
I love bumping my sa12
How do you use car audio at home what do you use
Mine is still going into protect after I turn it up a lil but it plays at low volume I went over everything and it’s still going into protect when I turn it up
Forgot to say to check for to low of impedance, alot of times if it's to low it will send an amp into protect.. I cant believe believe people dont actually know how to trouble shoot there stuff, blows my mind!
And thermal protection happens too, when amps get hot from running on low voltage or running for hours and hours long in the heat.. most good amps will protect themselves before any damage can happen, other crappy amps will just self destruct
@@tankdog03ifyexactly im 15 and i already know all of this
My amp hasn’t been turning on for a month, now it turns on randomly, and it will play music for a little bit, and then I hear what sounds like clipping and the amp shuts off. What could it be?
My battery reads 12.6, connection at amp neg and pos 12.6, but when I ck power remote it reads 11.6 what can be wrong? The amp testing is a hifonics Brutus ? Thank you
My amp started going crazy I was driving and then my subwoofers just went full blast and would not turn off even after I turned off the radio and turned my truck off it still kept bumping full blast and wen I opened my door it cut off?
I'm getting very low output. Subwoofer barely moves. Brand new head unit and amp. Any idea?
With people like you live is much easier. My amp stop working like 2 months ago. I couldn't get a new one cus kids, holidays, etc. I finally took my amp to Audio Express in Phoenix AZ, on Bell Avenue and 51Av. My budget was 200. I took my old amp, I asked them if it still work and if not how much will cost me a new one. They took the amp and came back with the bad new that it didn't work. For a new amp and labor was 450. So that was a no go. I bought an amp for 95 in amazon but it didn't work neither and it was to big that it didn't feet under my seat. I bought a Pioneer for 170 that is on his way. Since i have the weekend off i found your video and i follow step by step. I found power coming to the amp, power in the remote, but nothing on power and ground, i follow the ground cable it was loss and rusty. I created a new ground for the cable, in preparation for my new amp next week, i connected all the wires just to see what could happen and OMG light went on in the amp. I play music and the amp was working perfectly find. It was just a bad rusty bolt. Thank you your video i save money and i was able to do it myself. Sadly i found out there are some audio car business they can tell you otherwise and sell you 450 amp and labor, knowing my amp was working.Thanks for taking the time doing this video and sharing with us.
I have power to my amp but no power from amp to sub... Can you help please
WB Derrick!
What if you have no AC voltage from the speaker output?
What about the bass controller, I have no sound on my subwooffers
Hello my names mark, the problem I’m having,amp turns on fine but when volume turned up amp go’s in protect,when I lower volume it turns back on,running 0 gauge wire ground is straight to chasie,amp says it is 1 ohm stable so that’s how I have woofer wired it 12” duel 4 down to 1 ohm please help lol
Thanks for the video. Very very helpful. One question, What if your speaker outputs reading come up with no readings. Should I change the wire connecting it to the sub?
When u checking do car needs to be in the acc mode
I worked at a show that warrantied a amp 7 times. Could find the issue. Then a buddy came up and noticed the guy ran the ground to the body of a 96 ranger that had broken body mounts and the guy used the body bolt.
One channel of my amp is intermittent. Sometimes it works when it turns on but most times I need to momentarily crank the volume way up to get the connection to happen or tap the case of the amp. Bad solder connection somewhere?? ideas?
Check the RCA cable. Cable could be shorting out at the ends. Try switching cables L/R for R/L to verify if the other channel is doing it. If so, bad cable.
II got a kicker KX 1200.2 and keep going into protection mode there's no speaker wires on it no RCA any time I add the ground and the hot and the remote and goes straight into protection Mode I changed the hot wire brand new the ground is brand new and even the remote is brand new and when the stereo headsource turns on it turns on the app and it goes straight into protection mode nothing is on there like I said no speaker wires no RC a's nothing has just a hot ground and remote what do you think I even put my old amp it's works
AWESOME VIDEO AS ALWAYS SIR!!
Hi,my amp is that One channel not working and the amp is brand new what could be fauity
I’m having issue is it possible the amp broken
Power is on green light or blue light comes on no soumd i bought it from b stock. From car auto dealer i never got to use the thing. ... What would you recommend. ..
Already. Trouble. Shoot. It. Best. I could. In both. My vechles. I changed. Rca. On it. Been doing. Car audio. For. 15. Years. Lol. Did. Have. One. Them. Handy. At the time. I. Have my remote. Wire.

Źt Everything. To. Tes
Will u all fix my cab audio 1600.1
What if power won't turn off and can't turn up gain or volume without clipping
Flashing blue light on aSFB at higher volumes and no sound until I turn bass down
Same issue with my sfb 3k
First!!
Love your videos Derrick 🔥🔥🔥👍
Second
Just for take your time for do the video...! Thank you man!
my sfb 8000 reads 2 volts when the car is on and then 12. something volts when the car is off what could cause need help bbaaaadddd!!!!!
