[QUOTE="Motorhead87, post: 8697395, member: 678909"] Will you all double check my thought process here and make sure I am thinking of this right? I plan on getting (1) Audiofrog GB12 sub for now and possibly adding another later on in the Tahoe. Really trying hard to find an amp that works for this entire timeline that isn't a crazy power hog. Here are my thoughts. I will get the GB12D2 since it is a dual voice coil it can be wired to 1 or 4 ohms. I'm looking at the Pioneer GM-DX971 amp which puts out 500w @ 4 ohms and 1200 @ 1ohm. I can run the single sub for now and wire to 4 ohms and have 500w to it, then when I get a second I can wire them both to 1 ohm and have 1200w for them. I've been reading a lot about Ohms law and trying to wrap my head around this. There are so many variables to consider that it starts to get overwhelming (wiring in series vs parallel, effects of dual voice coils, etc). With this amp assuming an 80% efficiency I am lookin at barely anything for amps being pulled from alternator for now. [/QUOTE]
