kl0wn Posted May 23, 2012 Report Share Posted May 23, 2012 Because If I get one big battery for the system, what will start my car? So you've been using that single small battery by itself to power your amps? Without being hooked up to your alt, or main battery? Just curious since that is how your responses are looking. As others have said, you are only pushing 1500watts, 1 big battery up front should be fine. If you really wish though, you can put 1 big battery up front in the engine bay (what starts your car), then wire a second battery in the rear parallel with the front battery, then run your amp off of the battery you put in the rear. That way, the battery in the rear (the one you have your amps hooked up to), is receiving current from the front one to keep it charged. So you don't need a "switch". 06 Mini Cooper S Sundown, SoundQubed Cadence, XS Power 151s Sealed 155s Outlaw Windshield @ 37hz Link to comment Share on other sites More sharing options...

The idiot who installed it hooked my main battery and my audio battery together. Yes I was getting charged by the alt. Link to comment Share on other sites More sharing options...
Jordan Kushner Posted May 23, 2012 Author Report Share Posted May 23, 2012 budget? and agreeing with the others, theres really no need to have a backup battery. I already have the battery so I am putting it to good use. And I go to a lot of shows and run my system. When the car won't start I will push a button and it will switch batteries.

The whole thing is getting rewired. This is how the genius audio guy rigged it up. He had the whole system running off of that 600 Link to comment Share on other sites More sharing options...
Trey_Dog650 Posted May 23, 2012 Report Share Posted May 23, 2012 if you wanna run a different set of batteries for the audio only, might as well get another seperate alt that charges at 16 volts and get some real power!!! it wasnt running just off the 600. it was running off of your whole electrical... did you even have any voltage drop?? 13 Kia Forte Build! 07 Hyundai Accent Build ***Super Seller*** N8ball2013 And then he gets to say ok all you guys were right. im sorry for being a dummy poo poo head.
