Of course he has to watch his gain or he'll clip the piss out of the subs...on the other hand if his ears are any good he'll know when distortion is present and turn it down.
weve run sx 12s on a ss 6500.. they can take a lot of power on a proper charging system..
for those subs i'd not run anything under 2000rms.. they are not very efficient and need power to make them shine
this being said.. minimum big 3 and good batt or two.. just don't use the gain knob as a volume control and youll be ok until you start running up in the power range
if your gonna play it loud most of the time.. get an alt or youll regret it when you clip and amp/sub to death
well what alternator would be the best/ cheapest since the amp and subs are costin me ALOT. im runnin outta money. OOOO and how would i run a second battery?
i would think a kicker ZX1500.1 should do it! but u need the dvc 2Ohm for it to work
