I bought a 2k4 without the Mach 460, cause I thought I'd be buying a 2k5, but didn't.

So I have a 2k4 with a Alpine CDA-9833 and the iPod adapter, since it looks like I'll be having this car the duration (5 years) I would like to replace speakers and possibly add an amp. Any good suggestions to what will sound good with the head unit question?

TIA!

This is a non Mach 460 car, so I'm talking doors and rear deck...I'd like direct replacements, no cutting...
