Found an interesting radio counterpart under my dash.

On the back sode of the radio, there's a sticker. It was re-worked at some time.

I took down the RT speaker.

Forgot. It's a '71.

See if you can contact Jim (Norsky)  He lives up dere in dat Mn place heh??

      I suggest that you check with our supporting vendors for replacement speakers. The stock size is 4x6. A big benefit of going with an aftermarket speaker is having a separate tweeter built-in for better high frequencies. That helps to hear the music over the rumble of a big block!

Yes, they are 4x6, but I don't think you can connect "new" speakers to your original radio.  The circuitry is not compatible (something about ohm's I believe...).

I think they sell speakers that would fit the original radio; but you still won't get much out of them.  You could also go the other route; which is to replace the radio and speakers.  They sell some that have the decent 70's look face-wise, but have today's goody's (electronic circuit, aux input, ipod connection, sub connections,...).

That is simply the stock amplifier for the stock radio. The space available for the radios was limited, so in order to make it work the amplifier had to be a separate component. ALL early Sharks with a radio had this component mounted on the firewall. I believe the stereo systems had one other component mounted up there, too, but I may be wrong. In '77, a console re-design allowed the use of a "normal" radio head, ending the use of the separate amp system.
If your radio has a small, round, yellow/amber  light in the upper right side of the dial, it is a stereo unit. If it does not have the light, it is a mono unit. I think what you have is the basic, mono AM/FM radio set-up.

Thanks for the advice.

I've found a few Sony 4 x 6 speakers at the local walmart.

Hey Aaron,  I don't see any problem for the factory radio in replacing the stock speakers with aftermarkets. I recently changed out the original 4x6's (10 ohm) with a new pair of 4 ohm 2-way speakers, and the overall sound quality is improved. As always, avoid turning the volume up past the point of distortion (clipping).

Nope; I'm not certain that you can't, but a quick google search turned out these 2 interesting thread:

1) forum where the guy seems to say you have to use 10ohms aftermarket (sorry for a link to another forum...) http://www.digitalcorvettes.com/forums/showthread.php?t=38469

2) this guy sells classic car speakers and has really good info.  Seems like not having hte correct ohms would make the wires run hot... too hot....

Again, I don't know for sure, but something's telling me you have to find the correct one's.  Even if the sound comes out fine; it doesn't mean you won't burn the wires...

You don't have to buy from him.... but give the second guy a call; looks like he knows what he's talking about!

and btw; you will most likely find out that aftermarket 4x6's don't fit "exactly" in the original 4 holes.  I think I got 2 ok, a 3rd fine and forced the 4th.  If I remember correclty, I had to bend/twist the speaker bracket a bit.

     Hey Aaron, I've still got those Delco 4x6 (10-ohm) speakers out of my '78 that you are welcome to have. They are in good shape - I changed them for speakers with tweeters to get more highs for my tin ears. I will be glad to send them to you, just PM me or send an e-mail with your shipping address:
