Ok thanks.

I was going to get this one:
I don't want a high-powered one, just something to fill in the bottom end.

I did some more research and I found that the sub has a remote on wire, so I'm assuming that there is a relay associated with the amp that flips when the radio receives power. So even if I tapped into a constant-on line it should still not draw any power when the car is off. I still want to tap into the heated seat fuse so I don't have to go through the firewall though.

Sorry if I'm not making much sense, I've had a 3-4 day crash course in car electronics.
