Car Off Extended Play Time

[ItsAdam1]

Hello everyone I have been a long time reader and have only posted few or no threads, any how I need some help. I am trying to find some information as I continue to build my system in my 96 Impala SS. What I am planning on doing is a full audio and video set-up. (video 2 15" screen under the hood, 2 15" screen in the trunk lid, alpine IVA-D300 or possible a carputer for a head unit and one more screen for the rear passangers) and far as audio, I have 2 12" JL W6v2's on JL 500/1 and JL 300/4 power the front stage, which is a set of Morel 6.5 in the doors. My problem now is I was to be able to power the system for about 5+ hours at a car show. I have plans to run a tripple battery set-up with 1 starter (red top) and two stereo batts (yellow tops) I am running the stock alt right now which is 140 amps, Will two xtra batteries be enough for the hours I want to display my set-up? Is there some sort of converter I can use to connect the whole system to a 110-120v current?

if you want to be able to plug it in, hit up Powermaster.com and get a battery charger. Steve said they kick ass and it'll keep you batetries charged which in turn lets you stay on.

U can get a power supply or 2, 3 or 4

80 amp supply. 3.6” x 11.6” x 9” 7.5 lbs

High Current Power Supply

Battery charger (when used with optional SCM)

Ultra small size

Temperature regulated fan cooling

Can be paralleled for higher output requirements

But understand this you may be able to plug one of those in a outlet...

I doubt 2 that a lot of current....

They also charge your battery if your not using it at 100%

Good Luck!
