I ran a factory wet and a Kinetic battery for about three years before going Lithium. Just get a battery isolator. $50 or so. It separates the batteries when the car is off. It ONLY connects both batteries when the ignition is turned on.
@Michael Scott lithium is best in my opinion if you have an upgraded electrical system. I upped my amperage and wiring in my car from like 90 amps to a high output alternator putting out 300 amps of power. Dual Guage 0 runs for power coming from the Alternator to the Lithium Bank. My car keeps a voltage of 15.2 and my system when it hits rapidly recharges due to the high Amperage output from the Alternator. Lithium outputs power FAST. No bottle neck to getting power it the amp asks for it.
Im not trying to go that far. I just got upgraded door speakers and two 8s. But in total i am gunna be running about 2000watts rms of amplifiers. (In my car im running about the same with 4doors and a single 15 and suffer major voltage drop). I honestly feel like just a second wet cell or a replacement for AGM would be the little bit extra i need to stay in the healthy zone... but my batt under the hood is literally brand new as of 2 weeks ago so i dont wanna just replace it if theres a possibility i can add a second battery for the same cost@@KerryLNeely
Once again great informational video. But I'm currently running a wet cell under the hood and agm in the back for a about 2 months now , before I did ran it I read up on what you just explained and came across battery isolators .Bought one and ran from my wet cell to the agm in the back ,so far with car running my wet cell is holding volts at 13.8 while my agm is holding at 14.3 just hope it stays like that, but still planning on replacing the wet cell with a agm, but keep up the good work brother, I rank your channel up there with Steve mead, always waiting to hear your knowledge you provide us true street beaters thanks
@@yougod7253 omg I'm trying to figure what agm to get for my system and MB explained it well.but I saw the comment that you've to charge it ..who wants to do that once a week open hood ECT. For example what if you forgot to charge what happens?? Is true and for any AGM?
I've had so many systems in my vehicles that I've installed and they've all had eventually failed due to the battery dying or the alternator til I watch these videos this is a great channel.
I know I'm a few months late, but I just installed a battery isolator to correct my agm/wet cell imbalance, it was my plan from my builds inception and its powering fiercely. Thanks for the much appreciated channel, keep it coming
Very well broken down and I like you terminology you break it down in understandable term ,now I’m about to do the math on my set up and see where I stand ,however I did run 2 AGMs ,got a stinger up front and Xs in the rear.but ahh as always Maryland showing ❤️💪🏾
Great information. I was running a wet cell with with a AGM battery now I have a D6500 under the hood and a SMS-220 (Northstar) in the back. I still have the stock alternator and I still get a little head light dimming at night but nowhere near as bad as it was with the wet cell. I guess a 370 amp alternator is next on the list.
Does your alternator charge your AGM battery? I'm having people tell me that an alternator won't charge them. And I just ordered one so now I'm concerned about charging it. Thsnk you got any info
Wish I had found your channel before I just bought This big wet cell battery. I needed for my truck anyways at the time. But had I know about agm before I got my system I would’ve BEEN gotten one. Much appreciation bro for all your knowledge.
Stock 130 amp alternator Big 4, yellow top optima battery under the hood with xs power d925 battery in the trunk. All 0 gauge ofc wires for single fosgate t1 12 800 watts rms subwoofer wired to 2 ohms on a kicker cxa1200.1 amp. Happy with my simple setup 😊
Agm charging wet cell. I never play my system with engine off. My HO ALT 400 AMP is powerful enough to run my system and keep my two wet cells topped up. . Even if I swap my rear battery to AGM and it re charges my front wet cell when engine is off, what does it matter. ??? Soon as I start my car , the ALT kicks in and tops everything back up. I assume this is only a problem for people who crank up their system with engines off ?? You the boss brother , from U.K.
You can mix wet and agm if you run an isolator. Just like lithium and wet or agm. How you run the system also matters in sizing. If your doing SPL using sine files or demos all day you probably want more power than rock music at 1/4 volume most the time.
Thank you for sharing this information I almost made a bigger battery purchase as of right now I have two agm 44 Ah so getting. Another of the same will be better idea instead 😊
Ya I could use a bigger alt. Right now running the taramps smart 3 off of my stock alt and xsd3400 so far so good. I'm gonna keep an eye on it and top it off every wk or less being that I live in the northeast 20° today......no dimming what so ever. Also I use a old school toggle switch to cut any power going to my sub amp...
by the agm charging the wet cell battery every time it shut off, is a good thing meaning u dont have to worry about your battery dying, its always charge?
Wait, so when i have the car on my wet cell sits at 14.8v As soon as i turn it off it instantly goes down to 12.~ I take it as the batt only can store 12volts but if the alternator is running it can push 14volts through it. So does AGM actually store 14v? And is that why it always tries to charge up the wetcell when the car is off, cuz that wetcell will drain instantly to 12 without the alternator and then the AGM wants to send power to the low voltage to equal out the system
so i have a smart 3k on 2 skar evl 15's i have an Agm 55ah up front and 55ah in back with 300amp alt. big 4 done and all 0 guage ofc. Would i need anything else if i upgrade to 4 15's and the taramps smart 5k ?
You don't need a high output alternator. It'll just take longer to make those battery banks to full charge. Simple as that nothing more nothing less. If you battery bank is strong enough you can power 6k RMS on stock alternator. Seen it done
My system is putting out around 1200 watts and i’ll need around a 150 amp battery, however my alternator is rated at 130 amps. Do you think i could get by if i keep charging the agm battery or is that not a good idea?
Come on man. If you are running 2+ batteries, than you need a switch on it. If running 2 + batteries, they should all be the exact same battery. That said, most cars' charging systems are designed for wet-cell batteries and will not function nor charge properly an AGM battery. You could disconnect the ECU reader and just run an external regulator though.
What's up bruh ..I'm from South Carolina ..I have two svr 12s from skar audio d4s .. I need a good box for them ..let me know your price and I would love for you to build me a box ..
Lithium Is the future. 45ah Lithium battery runs my car and 5k audio system. No dimming of lights. With a HO 320amp alternator. And it shaves Soooooo much weight. AGM batteries weigh ALOT.
So a vehicle with a 160 amp alternator with a big three upgrade (already understanding that all the big three does is allow better current flow and doesn't add more power)wouldn't be sufficient for a 1200 watt class d amplifier? Thanks in advance if you answer 🙏
That is sufficient... you should be able to see 1200rms and a little more ...possibly. Depends on amplifier and enclosure ability to limit impedance rise
I've been told that an alternator won't charge an AGM battery. But people replace their wet cells with them. How do they charge them besides putting them on a charger every so often. Doesn't the alternator do something?
So can you put the agm up front and the wet cell at the back so when you turn off the vehicle and still playing music the wet cell battery is still charging from the agm battery??
I have a 2015 explorer just changed my under hood battery to xs power d6500 and I added a xs power xp3000. I was told my stock alt is 170 do I need to change it? Im running two amps 3k and 1200
Stock alternators are only designed to run your stock electronics + a small percentage to compensate for small power surges and natural aging of the alternator. When you add extra batteries, you add to the work load of the alternator; so yes, you definitely need to upgrade your alternator.
Help me MATH is my worst subject.i was a HIGH HONOR STUDENT until high school math..i pulled a 28 average all year in 10th grade..i got the big 3 my alt is 110 and i have 2 strapped mono 1500watt ea on a stock batt..please help..thanks
what battery do u recommend for a 1000rms system on a stock 200 amp alternator? im having trouble which is the amps the reservce capacity ? i cant seem to find a battery with 120+ amps
Atleast MB explains stuff clearly.. gives us the math.. dudes a certified audio legend
Don’t do that.. I’m still learning as I go!😃
Don’t nobody explain this stuff more straight forward then this man i swear🤝🏾🤝🏾🤝🏾
I ran a factory wet and a Kinetic battery for about three years before going Lithium. Just get a battery isolator. $50 or so. It separates the batteries when the car is off. It ONLY connects both batteries when the ignition is turned on.

Don’t forget to get a charger for weekly or monthly charging of the Agm
Me too and I have no problems. I do charge it bi weekly though.
What you have to charge agm batteries like once a week?

Does AGM batteries from Samclub & Costco would run well or go for the the top dollar ones? I figured the warranty you can't go wrong.
This was great to learn about King! 😁💯
Great info, saved em alot of time. Salute.
Great explanation. Keep it up.

Great video man i was just wondering about batteries u answered my question
Man thank you. I never knew nothing about this
Damn...you dropping jewels
Priceless learning lesson!
What about lithium batteries in terms of discharging. I haven't had any problems with mine but should I have gone with agm instead?
You good.
Does this apply to today in 2024? Any new battery technology like lithium.
Well said bro
by the agm charging the wet cell battery every time it shut off, is a good thing meaning u dont have to worry about your battery dying, its always charge?
Lately I've learned if the car is running the alternator primarily powers the amp . when the demand is high then it turns to the battery.
Fact
Didn't know that, good stuff bro!
Can I run my AGM straight from the alternator, by-passing the wet cell for my car?
Alternator need to be half of 600 amp battery 🔋, or the half of the 125 amp load I'm running from the 100 amp, amp , and the 25 amp of the 25% ?
Thanks for all the info
Do they same rules apply if you’re running a Optima Yellow Top Deep Cycle under your hood & an AGM in the trunk??
They both AGM
Thanks dude. That was perfect bro.
Thanks my brotha for your knowledge
What about diesels with dual batt set ups? Still needed for 1000ish?
Big 4 upgrade, you solid
I didn’t know that. Now I know. Replace the car battery first. Then get a battery for the back. Got it.
I'd love to see a video of gain over lap and differences in dbs
Wait, so when i have the car on my wet cell sits at 14.8v
As soon as i turn it off it instantly goes down to 12.~
I take it as the batt only can store 12volts but if the alternator is running it can push 14volts through it.
So does AGM actually store 14v?
And is that why it always tries to charge up the wetcell when the car is off, cuz that wetcell will drain instantly to 12 without the alternator and then the AGM wants to send power to the low voltage to equal out the system
But what if you not running the amp at full power? I am thinking of purchasing a JP23 mono amp but will definitely not be trying to run it at max.
Is it ok to run a 70 ah agm and a 100 ah agm in parallel or should both agm batteries be the same amp hours?
They can be different amp hours
thanks for this info brother
Hell yeah boy I love this shit. U like my mr Miyagi. Thank you for the videos
Thats why I use isolator with wet cell an agm
Thank you. Man
Man very informative ✌️
so i have a smart 3k on 2 skar evl 15's i have an Agm 55ah up front and 55ah in back with 300amp alt. big 4 done and all 0 guage ofc. Would i need anything else if i upgrade to 4 15's and the taramps smart 5k ?
Amp hours or amps
lithiums?
You don't need a high output alternator. It'll just take longer to make those battery banks to full charge. Simple as that nothing more nothing less. If you battery bank is strong enough you can power 6k RMS on stock alternator. Seen it done
So do you double the batteries if the xs power batteries don’t come that high with a hood alt?
3 sundown & 4500 nemesis & a wet cell in front..WHAT KINDA BATTERY 🔋 U RECOMMEND IN BACK BRAND & ALL ???
I have 12k what battery should I run
Is that the RMS of the Amp your talking about?
So can you run 2 wet cells?
Thank you!✌🏾
Is a marine type agm better for car audio than a starting type agm?

What size agm do I need under hood same as one in back or can I do a small er one under hood
Lol and don't forget the 4 channel needs power also
Can u plug up a battery tender to this battery for a complete charge?!?….
I have a 1000w rms amp my alternator is a 130 amps what size agm battery will I need

how much difference does an agm make over a wet cell?
AGM no occasional Fumes.
