now for my amp .
where do i find the stock amp to replace it with this one ?
how do i run all speakers to this amp?

 

I believe that the amp is above the parking brake. and find a good place to install the amp and just run wires to the head unit from there... I usually tap into the stock speaker wires to get the sound from the amp to the speakers.
