Ok, I'm no car audio expert, so I figured I'd run this by the bbs and see what people think.

I'm trying to get something that sounds good, but doesn't cost an insane amount of money and doesn't take up alot of room.

Head unit: Empeg + Tuner, no cd/tuner unit.
Amp: Rockford fosgate Power 550x 65w RMS x 4 amp.
Speakers: 4 Infinity Kappa 5x7s 2 ways that handle 100w RMS/ 400w Peak.
Sub: Infinity Basslink 10" Powered sub with 200w class D amp.

The basslink gets pretty good reviews, and is small enough I can still use my trunk. The rockford amp is right around what I was looking to pay and has a variable crossover, unlike the MTX thunder I was looking at earlier. The speakers are the best 5x7/5x8s that I could find for the price. Unless anybody knows anything better that can handle around 60-70 watts.

It'll be professionally installed, but I havn't found an installer yet... Is there anything special I should look for in an installer?

Thanks for your help.
