Thanks for the replies guys. My amp is the Audiobahn A6004V. Supposedly, it is rated for 75w@4ohms and 150w@2ohms.
I've got some Rockford Fosgate Power 6x8 coax I want to run in the doors. They are rated for 75w and are 4ohm speakers.
The Rockford P2 12" sub seems happy bridged off the rear channels. According to the amplifier specs, I'm giving the sub 100w more than rated, but if the specs are slightly overrated...
One Area I Need to Address--
I still need to install 4ga wire to the amp. It currently has 8ga. The built in voltage meter on the amp is all over the place when the bass hits. At idle it's ~13.8v, but when I really crank it I've noticed it'll drop to <12.5v. Dropping 1-1.5v can't be good. This concerns me.
I have some quality 4ga wire (Kicker Hyperflex) in my garage. Looks like I'll really need to get that in there once I get those front channels pushin' 2ohms each.
Thanks again for the help and comments.
