Scratchy sounding speakers
 

Hello everyone,

I've been working on tweeking my 94 Blazer back to excellent condition.

One of the things I did was to replace the radio head on the dash, bought a refurbished ECU under the dash, and replaced all four speakers.

After doing all of that, I expected the radio to sound like new. Zilch.

The sound from all 4 is a little scratchy, but the rear speakers are practically worthless. They sound like they're blown.

Anybody out there still working on these things?
