Thanks for the replies. The wiring gauge was my primary confusion. I only used the 12 gauge because that's what bazooka supplied, and no I'm not powering the sub off the head unit. I'm not that much of an amateur. Haha. The sub has an amp built in that's being directly powered. I'm just looking for a 2-channel amp, 90W rms tops (as per the speaker rating).
My only issue is connecting a new, thicker power cable to the wiring harness. I don't really know how to do that.
Yeah, I'm gonna change the speaker wire. It's whatever crap the dolts at Best Buy used. They did a terrible job. I've had to take my car back there twice already for problems with the install. I'd make THEM fix it again, but I lost the effing receipt, which I need for them to honor the install warranty. I only had them do it because I got the speakers for Christmas and didn't want to install them myself in my frigid-arse garage. Lesson learned...
