^^^^What he said.Hifonics is okay. Not the best, not the worst...
Dont buy a cap, buy a new battery. You aren't going to run 2k rms on stock electrical.so if a new battery and hopefully alt is in the plans, but not to be bought right this instant, should i buy a cap to kinda hold me over till i can upgrade my electrical system? i know from reading through here that caps don't really do too much, but hey it couldnt hurt right?
