kinda new at this stuff but im gonna buy a 12in IDMAX with a xtant 1001x amp in a ported box and i was wondering if ill need a altenator and an extra battery?
what car? what alternator do you currently have? in many cases a new alternator would definetly help. as an example. i have a stock 130A alternator(which is large for stock) and i have a 1000w amp and my lights were dimming. i had to get a batcap800. so most likely you'll need a new alternator or a battery. either use a yellowtop or batcap800. but another good idea would be upgrading your big 3, something i still need to get around to doing.
