Hi there. Just my $.02........... Why not go with the Rockford Fosgate HU and the 8 card changer....... The unit comes with a loading dock that conects to your computer. Just download the MP3's onto the card,i believe they are 64mb,and slip it into the changer. No need to burn MP3's onto CD. Or go the route of downloanding a MP3 to WAV program, convert the MP3's to WAV's, and burn the CD. Works for me. If your intrested in the program, go to ZD.net. Sorry so long.
