I am in the process of getting my 75 vette back up to driving condition and started testing all the electronics. Everything works fine and had 2 bulbs that needed to be replaced. I know the C3 stereo sucks but I cant even hear it with the car turned off and the windows rolled up and the stereo turned to WOT without sticking my head next to the speaker.

Is there a factory amp or something I need to be looking for? I mean its really low volume.

Yes, I am installing speakers and an amp in the back for the IPod but I want the stock system to work.

Get your radio checked out.

I can hear mine at 75mph with the top down and I have a 427 with factory side pipes...

Is it the original factory radio? There is a small amp behind the right side dash, its about a 4" place with aluminum fins with a round dish in the middle.

You could have a loose connection or the wires could be shot.

Yes. GM calls it a convector assembly. It's the final output for the speakers. AIM shows it. One transistor for mono; two for stereo.

ATIS

Its completely stock so I will take a look for the little amp. Thanks everyone.

This widget: common stock locaton.


This one is mono (only one transistor); stereo units are larger.

Crap, from the looks of that it is WAY up inside the dash. That explains why I couldnt see it by sticking head under the dash. I have been avoiding pulling the dash apart. It hasnt been molested and I hate trying to get a dash back in rattle proof.

The passenger side dash is the one part of the dash that is easy to remove. It's just a couple of screws on the jamb side, three across the top, and the screws from the radio bezel. Remove those and you should not have a problem wriggling it out. The top kind of tucks under the top dash pad.

ATIS

Excellent info! Thanks. I will try and get to it tonight after soccer.

Easy Mike

Naw. It's usually right behind the passenger's dash pad. Before you pull the pad, look around under there (on top of the heater box) and see if you can find the pig tail connector (green, blue, and yellow wires). It plugs in to the rear of the stock radio.

ATIS

ok, will take another look. Thanks again everyone. off to a job interview!

ATIS

Found mine, anyone have a part number for it? I cant find it on Zips or Wilcox's site.

Easy Mike

I'm not sure it's being reproduced. Post a want ad in the Parts section. I've seen the transistors by themselves listed on eBay. Doesn't take much to swap out the transistor.
