Speaker, Sub, Amp, Help!!!

[davidbeaver1]

I was thinking about doing the same thing. I have installed a Kenwood HU and new doors speakers, then bypassed the factory amp all together. The HU has more than enough power to run the door speakers as loud as i want them. It would be cool to be able to use the factory amp to power the factory sub just so I don't have to add anything else and clutter up the interior anymore. My truck is a 2001 Non-Bose and the amp is just behind the glove box. I bypassed the amp there by just running wire from the HU and tapping the speakers at the amp. If I could get signal to the amp and use the existing amp and wiring, that would be cool, but I don't see wiring diagrams anywhere for the other wires on the amp, so I'm not sure what to tap into.

I just finished replacing all 4 door speakers with some nice Rockford fosgate 6.5s I just wanted to improve the sound which in my opinion sound fantastic. I'm using the factory head unit in mine and then tapped into the rear sub (which was blown) for the LOC to my RF 10"s. I'm not sure if it will help but I used this wiring diagram to find a 12v accessory wire to splice in for the amp remote wire.
