So in this car I bought, it has the Mach 460 system in it. I pulled the mid plate off the dash and I can see the amp down there and hooked up.

To start....all the damn harnesses were unhooked when I got in there. I matched them up and all, and then obviously matched the harness with the aftermarket, as well as the black 8pin connector to the after market.

I turn it out, power is good, but the only speakers working are the ones at the top of the doors. The rest of them won't power up.

What am I missing here?
