Alright, For all you experts out there, here is where you expertise comes in.
I have a Panasonic Deck, 2 Infinity Pro Series 12 inch subs, a 750 watt bazooka amp, polk audio 6 x 9's, Infinity 5 1/4 inch speakers, and Infinity Tweeters, two 8 inch tv screens, a ps2, euro reverse guages, and 2 air compressors for my air ride, and only one battery. I already upgraded once to a bigger battery, nothing special, just bigger. Should i get a red top or yellow top, or add another battery, bigger alternator or what? Please help if you can.

 

What is the problem exactly? Im not sure, you havent specified. However with all that crap you have, I would advise you get a built up alternator and a big nasty Optima battery..if not two.

 

I would always suggest with any large amount of power drain over what came with the car, to get a built up alternator ( either stinger/ohio generator, or any of the other big names if you can afford it) or get your existing alternator rebuilt to a higher output. and I would def suggest a higher quality battery ( Optima, Interstate-Megatron, Stinger etc and so on)
Good luck.. what actual problems are you having? make sure to check all of your wiring, especially the grounds.. poor grounding causes LOTS of "not enough power" problems.

 

Double up your battery if you question the amount of power you need. With all that stuff you should be running two batts anyway. Just make sure you go with two equal size batteries, otherwise your batteries will only charge as well as the weakest link in the group.

 

def. i would suggest a built up alternator...that would help your power situation. i would also in turn get one of those optima batteries...just to be safe...you gota a lot of **** though...sounds nice! can we get some pics?
