    Hi sir, quick question for you, what are the size of the fuse that u use between the front battery and the rear batteries? Also, why are you fusing the same run of cable at 2 different places? ( close to front and rear batteries )

    • @AmplifiedCarAudio
      @AmplifiedCarAudio  6 років тому

      I’m using 300 amp fuses with a 250 amp alternator. There’s a lot of vibration and body panels moving that wouldn’t normally move without a system like this so I use one at both ends of the charging lines mostly for extra protection.

    • @ALEX-xd7ko
      @ALEX-xd7ko 2 роки тому

      You fuse at both ends to prevent fire lol. You want your fuses within 12' of the amps and batterys . The point is ... cables actually vibrate and move as amperage moves through them. Not only because its a " system like that" a 10ga wire on 200watts will do the same thing with literally no base lol. The fuse is to disconnect the battery in the event of a meltdown aka dead short. In reality if your alt at max does 250amp you should only have a 250amp fuse . Now the fuses to your amp can very but it is known fact that you need 100amp per 1000 real watts of fuse . So an amp that puts out 2k rms you need a 200amp fuse . 3k 300 and so on . The fuses to the amp not only protect the battery but your amplifier in case of dead short .

    Hi I’m running 3 batteries 2 under the hood one in the back of my suv. Right now I have positive to positive and both batteries grounded at different places for the two under the hood and the third battery ground to my seat. I have two fuses under the hood would I need another one to run power to my third battery or can I just jump it off my second fuse to run back to the third battery also would I need a inverter or anything? having power issues and I know I need a bigger alternator but have a big agm battery just laying around so trying to see if that would help

    • @AmplifiedCarAudio
      @AmplifiedCarAudio  2 роки тому

      Definitely a good idea to have a third fuse for the run of cable going to the rear battery. The seatbelt may not be a good place for a ground because there’s paint on the bracket and then paint between the bracket and the floor of the vehicle so you may not be getting the greatest connection.

      Not necessarily. An isolator would be used if you were going to be playing your system without your engine running. It would keep one battery from discharging so you could still start the vehicle.

    • @AmplifiedCarAudio
      @AmplifiedCarAudio  5 років тому

      The quick answer is yes. However it’s really going to depend on what you’re running for equipment. A 90 amp alternator or a 20 amp charger would also charge them. If you’re looking to run a “5000” watt Boss amp then you’ll be good. However if you’re looking to run 2 Crescendo 10k’s or something like that you’d need a bigger alt. and more batteries.

Know for subs i currently have 2 15s cvx by kicker, but just today i ordered some 2 skar audio ddx 15s subs.also have connect a clarion equalizer a kicker crossover and a epicenter. For batteries i have a 2000 hc kinetik battery to start the car and 1800 kinetik as a secondary battery but was planning to put the stock battery back and my 2 kinetiks for the audio so that will be 3 batteries in total.

    Thanks for the vid! But how does the alternator sensing lead fit into all of this? How can the alternator be monitoring only one battery (under hood battery) and yet still charge additional batteries in the trunk which, under heavy load with music, will drain more quickly/at a different rate than the under hood battery? I should clarify: I want two batteries in the trunk and one under the hood, I want 3 separate charging cables at the alternator post, one for each battery. Thank you!

    • @AmplifiedCarAudio
      @AmplifiedCarAudio  5 років тому

      For my set up I have a 250 amp alternator and I’m using 1/0 cable which can carry I believe somewhere around 300 amps. My alternator connects to my front battery and from there runs to the back 3 batteries. Once the batteries are linked to each other you can almost think of them as 1 big battery. Now if you have an alternator that produces more then 300 amps or if you have more then one alternator then you would want multiple runs of 1/0. Now don’t get me wrong if you want to run all of that cable then you can do that it’s just not necessary.

      @@AmplifiedCarAudio Thanks a bunch! I was just having a hard time wrapping my head around how the alternator senses all three batteries when only connected to the front battery with the Sensing lead but you're right, it's just one big battery when wired in parallel. My FSM for my car states not to charge the battery in excess of 50 amps. I was wondering what would happen if I ran three charging cables from the alt, one for each battery and the sensing lead only monitoring the front battery? The alt would only charge the rear batteries based on the charge status of the monitored, front battery.

    Could have save yourself 10ft of wire had you ran it up the pass side and under . Seeing as you have a battery bank across the rear . It was completely pointless to cross over . All you did was add resistance and lower your amperage capability. Its also a good idea to ground your amps to the shortest possible point. And to the frame not a spare tire bolt that just runs through the body. I personally would have welded a ground bar to either side of the frame and ran my grounds . The way you wired your grounds and amps is why you have such high resistance.
