As always budget is an issue and you are in a car, not a listening room so don't go overboard. I've dabbled a fair bit in car audio so I'll give you my two cents worth. Blaupunkt never did it for me, I did like Alpine lots (but there were all sorts of reliabilty issues) and finally settled on Pioneer for my electronics. That would be head unit, CDP changer, amps. Be ready to install a big-ass capacitor or an extra battery if you get carried away with the amps. Speakers is a whole different gig... and as always you can spend megabux. If you want nice sound at a reasonable price try out Infinity speakers, and I do like MTX subwoofers. Best, Jeff
