Another battery will not really be a hole lot better.Your best bet is to buy a smaller pully for the alternator.You can buy the pully at www.ZZPerformance.com i think its like $15.Hope that helps you out. Justin

Maybe ask a local car radio installer, they load cars the teen-agers drive, I'm sure they'll be able to help you much better than the guyes in here will..

Very easy to put a 2nd batt in the trunk. Just mount the batt in the trunk. Run your power wire for your amp to your 2nd batt 1st then from batt#2 to your amp. You will need to ground your 2nd batt in the trunk somewhere I suggest drilling a hole in your trunk and runnin you ground through the hole and ground it out on the frame. Also if I were you I would put a second fuse block on your power wire close to your 2nd batt. If for some reason your power wire grounds out the front fuse will blow but if you have no fuse by your 2nd batt your power wire will still be hot and may cause fire fire=lotsa $ By the way I do have alot of experiance in car audio if you have any more ? just ask

the amp power wire idea sounds fine but i need to run a relay so the two batteries are both charged separately, to do so i have to hook the isolator up to a true ignition source in the engine bay but don't know where to find one
