Just installed a pioneer avh-p4400bh with the PAC wiring harness indicated for my 2005, but the front subs aren't coming on. All of the other speakers are working. Any thoughts?

check your fuses, the amps are individually fused.

Is your amp getting 12V power? You should see a light on the amp light up.
There is also a 12 off/on signal wire that is usually blue going to the amp. Does this have 12 V when the car is on?

Got it figured out. Didn't have the RCAs plugged into the back of the head unit. Thought the sub outs were there if you had some sort of aftermarket amp hooked up. Whoops. Thanks for your help though guys. It sounds awesome.
