That link has a comma thrown in so it doesn't work.
BTW, I just got an amp and a pair of 6x9s from
http://www.carmedia1.com also.
(Pioneer GM-X564 and TS-6995). Several places around the web had similar prices (one had the speakers for like $73) but this one had both the amp and speakers so I just saved myself a little hassle and bought both.
My 1987 Vette has the 1.5 DIN. I pretty much agree with 92TripleBlack about the brands and getting a regular din size (you can get a 1.5>1 faceplate-convertor--or whatever they are called).
I got one of the ones with the little "cubby hole" below from Circuit City--you have to ask them to go back and get it. I think they're $12.99. This will help me since the head unit I have is a pull out (http://www.sonicblue.com/audio/rio/riocar.asp) so it won't hit the gearshift when pulling it out (hopefully).
Now if I could just figure out how to:
1) get the Bose speakers out of the door
2) figure out this "common ground" thing
3) fit the 6x9s in the rear and use the factory grill (maybe requires making my own mounts, etc?)
4) maybe i'll just put the 5.25s in the dash and avoid the whole door thing?
5) get the power wire through the firewall.
etc etc
What a pain!
