i havnt done it myself but easiest way is to get a speaker to line converter just takes the speaker wires and converts to rca outputs youll need 2 stereo units for front and back, i can pick them in aus for 15 dollars each

 

So, speaker wire to these converters... these converters to the amp... and then from the amp back to these units? Any idea on the effect of quality?

 

no they convert the speaker levels from the mygig(anyradio for that matter) to line level so you can input into the amp then the amp connects to whatever speakers you want to use

 

Thanks... Will take a look in Crutchfield to see what they have available then.

 

So... would it be this?
