it would help, but you're gonna need something to charge it proper eventually.

Just say no to Ground Pounder Customs.

More box builds

some cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches!

I'm with captain stupid.

i sent them an email although i did want to avoid in having to buy a ho alt. If there to expensive ill just sell the amp or maybe just buy an 2 xs power batteries one for the front and one for the back. i have seen others with the 2500 and there voltage only drops to about 12.5 i know this isnt good voltage but isnt it still good for not clipping the amp?
