Figured it out! When we originally hooked up the amp we wired the remote into the ignition instaed of the remote out. (Same color wire...opps) When the Amp fried it fried that wire. We just ran a wire from the power outlet (only comes on when car turned on) back to the head unit in place of the fried wire and...viola...head unit is in working condition again. Now to see about the amp.
