All radios that are single din size will work great. Just choose the one that best fits your needs. I suggest getting one that has 2v or more preamp outs and wire it with a harness that is designed for using the preamp outs. I hooked mine up using a harness that was designed for using the internal amp in the headunit and it caused distortion. I had to splice in some RCA cables on the speaker wires of the harness to use the preamp outs.

The factory amp just has 1 set of left and right inputs for all 6 speakers.
To summarize get the harness that is made for preamp out (local shop is a good place to start) and use any radio you want.
