Depends...do you want to stay ABOVE a certain voltage? If so you are going to need more alternator power...simple enough. However you could probably get away with adding a nice battery bank to help keep the power above operating voltage.

500 amps is a lot of pull. Music is dynamic though so you're not pulling a constant 500A unless you're running a tone for 30 seconds or so. IF you are wanting to be at FULL tilt for extended amounts of time, a second alt o similar aperage, and like stated earlier, batts. I'd do a Group 34 under the hood, and 2-3 Group 31s in the back.


Im not the one you want to try to troll. Just a fyi for you.

Let me explain further. The oem atl is about 120 amps and i am getting a 220 amp alt. Along with the oem system in my audi a6 ( not to many parts for this car) I am runing a american bass vfl 400.1 (400 amps) a american bass sq 600 ( 50 amp) and factory amp ( idk bose : ) i also have 2 LC2I to run. My thought is that i am at 500 amps or may be more. I plan on getting a d3100 and a d3400 soon. I can say that i do like to listen to my radio at full tilt all day long. but Johny law will not have it. 1/0 gauge in my car nothing less big three and 400 amp breakers X2. What should i do to feed the beast?

IIRC, aren't Audi's electrical systems different from other manufacturers? I remember trying to jump start my boss' Audi and we were trying to figure out if it was the battery or the alternator that went out. We unplugged the positive battery cable, but it didnt work like normal. Audi's are wired differently. Not sure if this is going to cause an issue with you or not, but thought I'd throw that out there. Plus in his car, the alternator meant he had to remove the front driver's side tire, open up the wheel well, and there was his alternator stuck back in there. I think the battery was back in there too. Make sure you are getting the right equipment since it's an Audi. Not sure if anything has change and like I said, not sure if this will cause you an issue when installing and running a system or not.

What sort of Audi was that?! In my A4 Avant the alt is at the top of the engine at the front side and the battery up at the top on the windscreen side.

You're vehicle runs off of the electrical output of your alternator. The battery is there for starting and reserve capacity. If you have 500 amps of current draw you need a way to produce 500 amps worth of current. If you only have a 220 amp alternator you will max that out and then it will start to pull off of the battery to get the remaining amperage the system needs. But it will only be able to do this until the reserve capacity in the battery is drained. So you either need a bigger alternator and a few batteries or you need a battery bank with charging system that you can plug in over night to keep the batteries topped off like other people have suggested.

So if i was to get a 320-375 alt to reaplace the 220 how much battery will i need with either or? I am trying to keep the weight down. With the box, speakers, and amps thats like 200 extra pounds. The bats will add a extra 150 add that up and thats like one fat girl in my car (350 ibs). I dont think my st coil overs can take big girls. lol
