I have just recently installed a 1500 watt system and its true power well at night if i am really pounding away my lights dim pretty low and sometimes it even makes my speedometer move I was wondering what type of upgrade i should do guy at auto shop said to install a second battery one meant specifically for car audio. I‘m not sure the size of my alternator i just know it is stock
I got rid of lights dimming etc with installing a 40F cap in my trunk, next to the amp (30cm max from amp) But i need to follow up on my alt and battery, to see if they do well. Alt gets hot if it works hard, battery can boil if it has too much work (my system isnt doing either). Im thinking getting a analog volt meter that runs from my car lighter. Same with an amphere meter. That way i can follow it and see if battery gets charged enough. And follow the system jadajadaja. I know its a pain, but its like this if you have not big enough alt and battery. BIG 3 is allways good, and fast to do.
what kind of car you got? i would say a capacitor but i wouldnt use them i never had a good exp with those and next time you go to the audio shop ask them how much would they charge you to do a BIG3 on you, and make sure they use KICKER brand name wire when they do or else you just giving them money to use name brand wire but they are not so your pretty much getting ripped offfffffffffffffffffffffffffffffffffffff.
just install a capacitor close to the amp or amps it stores energy for when the amplifier is calling for it.they have many on line a 2 farad or bigger but not to big.and you should be running 1/0 gauge wiring from the battery to the capacitor,don't forget to put a breaker or fuse in the line close to the battery.then ground the capacitor to the chaise with a line as thick as the power line no longer than a foot to 18 inches.hook a distribution block on a 1/0 gauge wire to the pos side of the capacitor also then you can down size your wiring from the distribution block to the amp or amps.so on the capacitor you should have 2 power lines on the pos post and 1 ground wire on the neg side grounded to the chaise.then tighten up the contacts on the capacitor and don't over do it.and if your ever removing the capacitor never do it from the contacts themselves,or they will crack from the power that has been heating them up.hope this helps you out.i have installed many and they do help as long as your not running a 5000 watt system.have one installed in my jeep and aways use them when running a powered system.now when you go big like 5000 watts that's when you need the big 3 upgrade with a high output alternator.and read the instructions on charging the cap.its should happen slowly and they give you a small piece of wire to do it with.and you don't go to big for the reasons in the last write up.10 farad tops.
