Sound system power

[korn3172]

Im currently putting a sound system in my car. And im a little worried about the battery going flat.

Im putting in all pioneer stuff.

head unit with screen.
Component speakers for the front 150 w woofer and 120 w tweeters
6*9 5 ways in the rear 450ish
2 mono 400w amps
1 4 chan 350w amp
2 1400w subs

Im lead to believe my VT has a 85 amp alternator.
And i can get a 100 amp alternator fitter for around 180.

Do you think i will need it or anyone have a alternative. (Apart from keeping it low :P)

Thanks

Put in dual battery with an isolator so that the only time both batteries are paralleled is when the engine is running.

i looked at that, but the guy was going to charge me loads for the installation.

If your battery is in ok condition, and you aren't planning on listening to it for hours without the engine running you shouldn't have to worry. The stock alternator should keep up just fine

Awesome, thanks.
