I didn't want to spend a whole lot of dough on mine. But I got a kenwood KDC deck which i'm quite pleased with. Nothing increadible to look at but it's simple and matches the interior okay. For speakers I went with Infinity Reference for the 6.5s and 6x9s. They had the best high and mid range clarity that i could find. I don't need much for subs so i went the cheap route and got the DUAL 12s that come already in a bandpass box with a 450 watt amp. Nothin that'll break your ears, but just about anyone who sits in my car compliments the balanced sound the whole package gives. The kenwood deck was about 150, infinity speakers, about 300 for all four plus tweeters. and 200 for subs and amp.
