avenged4life Posted February 3, 2014 Report Posted February 3, 2014 Ok so right now I have my amp set up around 1200 watts, at 1000 watts solid on the amp there is 0 notice in lights or anything, when I start pushing 1200 point you can see minor dimming starting. I'm about to run 2000w rms to my 2 apline type rs and I wanted to know what would be the most cost efficient change to do to keep my car from dieing and what not. Thanks in advance. The current alternator is 80 amps. Its running no capacitor and has a single battery. Update: In the m3 the battery is mounted in the trunk in a sealed off compartment, The subwoofers take up pretty much the whole trunk so I dont really have any place to add a new battery at all =/ Would replacing the current battery with a much better 1 and replacing alternator with a 140 amp alternator solve my problems or not really? And is it worth it to add a capacitor?
SlamminBeats Posted February 3, 2014 Report Posted February 3, 2014 your options: replace starting battery with an agm of higher quality, like an XS power add a rear battery or battery bank get a h/o alt
Eroc3k Posted February 3, 2014 Report Posted February 3, 2014 your options: replace starting battery with an agm of higher quality, like an XS power add a rear battery or battery bank get a h/o alt Plus the big 3 or 4 to sweeten the deal!

SlamminBeats Posted February 3, 2014 Report Posted February 3, 2014 no caps and add a 140 stock or factory alt? that would be a waste your best bet is to do the big 3 under the hood or add batteries some how or change out your stock battery.
avenged4life Posted February 3, 2014 Author Report Posted February 3, 2014 big 3 wouldnt be under my hood only since the battery is in the trunk ;] but sounds good so just replace all the wiring with lower guage for now and hope that solves some of the problem? Also I meant replace the alt not add lol
SlamminBeats Posted February 3, 2014 Report Posted February 3, 2014 your gonna have to run the positive from under hood from the alt back to battery. big3/4 will be your cheapest upgrade to maybe stop dimming. I would try this first.
avenged4life Posted February 4, 2014 Author Report Posted February 4, 2014 If I were to replace stock battery is that a battery strong enough that it can recharge fast and keep up with a 2000w system on an 80 amp alternator or am I gonna have to run 2? If I run 2 should I be putting like a yellow top optima in the battery compartment and maybe running the wires to the current battery some how in my trunk?
SlamminBeats Posted February 4, 2014 Report Posted February 4, 2014 thats too hard to guess, thats like adding engine upgrades and saying will my car do 200 mph? dont know until you try tbh
