Why add extra batteries??

[meade916]

Theoretically wouldn't the battery still be running everything and the alt just keeps the battery charged on most cars where as the amps and car are pulling the power from the battery? Unless you have your alt ran directly to the amp..

Technically speaking.. That's what my ase book said..

I'm not saying that's my opinion persay

Edit, I saw it in my book while studying for my auto body finals..

nope. When the car is running, the alternator is doing ALL of the work...including keeping the batteries charged.

Batteries store electricity, alternators convert mechanical energy to electrical energy and charge the batteries.

In simplest terms a battery or multiple batteries are what is actually running your amplifiers, the alternator(s) are there to recharge the batteries.

actually you are wrong bro.....your ALTERNATOR(s) are there to supply the system and everything in the car while it is running. The batteries are only there for when you have more system then you have alternator and drop below its maximum charging ability during heavy use. That or if you are playing the system with the car OFF (like at the beach or something like that.)

basically while the car is running, the alternator should be doing ALL the work.

That being said, if I were to run 2k rms which would pull like what.. 200 give or take amps? If I had a 270xp alt, that would be plenty to run everything with a single batt yeah?

you would be MORE then good with a 270 amp alt. You dont need one that big for 2,000 watts but it will give you room for expansion.

You seem to be forgetting just like everyone else seems to that the car has to be powered b4 the system or anything else.

ive got a 275amp alt with an xs d2700 in back and dont see below 13.4v on music, it'll climb right back up to about 14.3 after playing which is generally where im at on a warm engine

i may be willing to part with my saz3500d to save you some cash, toss me a PM if interested

How so? I've taken that into account here. 70 amps will be free for the car itself, if the amplifier will take up to 200..

I understand that, I guess I oversimplified it a bit when I wrote it.... Even with multiple HO alternators chances are they are not going to meet the current demands of a very large multiple amplifier setup and having extra batteries is there as a buffer like you said to keep your voltage up. When your alternators cannot keep up with the demand the batteries would be used and then recharged by the alternator.

Current goes where current is needed is a better explanation than what I had said, the alts will power the amps when the amps are drawing current, and anything the alts cannot provide will be assisted by batteries.
