my 94 940 has a factory amp, my question is,I know i have to bypass the amp but do they make a harness for the amp? If not what is the best way to wire it? Just cut off the factory connector and just run new wires to the radio?

also my radio has wires for 4 speakers but the car has 8 speakers, do i just put 2 speakers to one channel on the radio?

Thanks

 

Basically yes that is what you have to do.
