Just curious - Does your Custom Autosound stereo sound horrible too?

 YES! I have a terrible one also. Dealer says it's the way I installed it. I just listen to the Chrome tips on the bumper and if my hearing aids are still in, I don't need any other interference with the wind blowing in the window, or over the windshield into the cabin.

Yes, I have one as well and the sound is terrible. It doesnt Matter whether its the radio or if I am using the auxillary in. The volume is horrible and fade makes very little difference. Im glad I have the side pipes to. They sound better anyway!

I have the Custom Autosound 6 series deck with pioneer speakers up front and Boston Acoustics 5X7 speakers in back (biggest that would fit in the factory 79 locations). I bought the I phone interface for it. Radio sounds OK but not spectacular. I'm sure thois is due to the antenna (had a LOT of trouble with it!), but if you get a strong station it is tolerable. The Pandora from the I phone sounds great, but not to the level of modern cars. I just figure it sounds WAY better than the 8 track deck and the blown speakers that were on the car. As stated above, the CS unit appears stockish, and that appeals to me. Didn't want a mpodern looking unit. I don't use it as a daily driver, so I'm more than happy wiyh it. I have never really used the cassette deck.

Has anyone tried the Retro Sound radios?  Their website is down right now.  I think these are different than Custom Auto Sound radios.

I just installed the Retrosound RC900C in my car. It is a basic unit and an easy install especially if you have the original harness still in your car. I fooled around with it a little today and the sound through the aux using an mp3 player(phone) sounds pretty good over the exhaust. The front speakers do need to be replaced and I have a set ordered. I will also add an amp at some point because more is better. Their customer service is very good. The knobs wouldn't stay on the control shafts...easy there Joel, I planned on crimping the shafts a little. They said to give it a shot and if that didn't work they would send out new knobs, shafts and prefit them for me free.

I tried plugging my MP3 directly into my amp using an RCA adapter I use to interface the MP3 to my home stereo. No sound....nothing. Odd. The amp was on...not sure what to make of that one. Plugged the deck leads back in and yep, it worked. Its all analog signals...should have worked.  

Has anybody found a good stereo that sounds good in these older vettes ?

I took a Sony with a wired remote and cut the back out of the glovebox to shove it thru and have the remote between the seats.  Trouble now is the remotes are wireless and won't work thru a closed glovebox door.

That's what I was thinking installing it in the rear somewhere maybe I'll see if I can mount it between the seats with a wireless remote  thanks for the suggestion

You gonna drive thru that door?
