Well guys hope someone could help. Thanks Lou

SC Speakers Amps and head units can all be found and bought here in the classifieds or on ebay. Could be a loose connection, bad amp, blown speakers. Till you pull it all apart who knows.

The tilt column. There is a great DIY one how to fix it here in the SC threads.

Just search "Tilt Steering Repair" in the search section.

Other then that...welcome

I agree fully with O.L.T.... the speakers are common to go after so many years, could be any the problems he listed. It will just take some looking into but can be fixed. As fas as the tilt steering goes the DIY thread is great! I had the same problem an it literally costs under a dollar to fix. The SC's are awesome cars and I hope you enjoy it as much as many of us have.

If its a Aftermarket system then the cracking noise you get when you turn the system on is from the Remote wire to the amp, just put a resistor on it.

And about the grinding tilt noise, wasn't there a DIY on that

Nope.

I heard the crack for the first time a couple of months ago. It scared the wits out of me, and came back shortly after the radio was turned on again if there was not an hour or so. I suspect a bad capacitor, but the amp (Nak) began to pulsate a couple of weeks ago. It is now dead and I am not in the mood to reverse engineer it to repair it considering the offerings modern radios come with.

I decided to replace the Nakamichi with a JVC unit and bass amp. New speakers, and finally chase down and document the rear window heater problem while I have things torn apart. After a lot of forum research I have completed the new wiring diagrams to match the JVC to the Nak plugs and the power antenna. I will post pictures to the forum when the install is done, with a separate posting to show what I find with the window heater. The good head and changer are probably going to eBay.

On the crazy side I am considering making the new faceplate surround of of something transparent and then putting LED's behind it with 4 frequency filters connected to a speaker line so the four different color LED's will dance in step with the music behind the translucent dash filler.
