Time to upgrade! I have a Kenwood aftermarket deck that I want to install. I have the wiring harness, plugged her in and fired it up but no sound! Realized that hey, I have a factory amp that is in my way. What do I do? I heard that my deck doesn't send the right signal to the amp to activate the power for the speakers or something along those lines. Help is much appreciated for I am installing 2 subs with a 1000W Kenwood amp. Thanks!
