Am I missing anything? Someone said something about a signal (RCA/patch) cable... I have no clue what this is, do i need one?

by the way, my rear stock speakers are 6.5" but I am getting rid of them and I mounted some 6x9's above the back seat and I am running the stock wire back to those

The RCA patch cables are run between the headunit and the amp. That's how the sound gets to the amp.On the amp/headunit you will see a red and a white round connector for it. You will also need a remote wire from the headunit to the amp so the amp turns on when you turn on your headunit.

looks good, but +1 on the remote and RCA's.

Remote wire can be any 12-16 gauge wire, usualy people go with blue, as its color coded. About 20 feet should do nicely, pick that up at any car audio store, or most hardware stores carry it.

Make sure to run your rca's on the oppisite side of the car as the power, and make your ground as short as possible, don't buy 10' and have it coiled up, cut it.

dump those sony subs and your all good...
