Well, I'm almost done building my system. Here's what I got.
Deck: Pioneer DEH-5 CD deck that won't give me my CD back sometimes! A new Pioneer DEH-P7700MP is on it's way though.
Speakers: 4" front and 5 1/4" rear Pioneer TS-G series with foam baffles and 14 gauge wire.
Bass blockers: 300HZ front and 150HZ rear.
Subwoofer: Visonik Dual 10" Bandpass V103BP
Amplifier: Profile HA1000 2 channel. Wired in stereo to subwoofer.
This is kind of a budget system. Pretty much less than $800. But I am very happy with the results. This thing thumps like no tomorrow and sounds great. Should sound even better when my new stereo arrives.
