Well... something happened that's never been encountered before. Was running the town last Saturday (day) and hopped in the HHR after my last stop just to find that the radio wasn't producing any sound!?
The interesting part was that the radio HAD POWER, would switch channels, and would goto CD (or AUX)... BUT NO SOUND!?
Seeing that the radio was ON... figured it was just a fuse-related issue. Drove it home, soundless, and fidgiting with it all the way. Turned it off and on, up then down, etc, etc... nothing.
Got home, checked the fuses... NEITHER WERE BLOWN
(e.g. Radio, AMP).
Miffed at the results, I pushed them back in and turned the car on and Viola!... it worked!!
Still have no clue as to what happened...? It's almost as if there's a breaker on the amp that shuts it down if it gets too hot, although we were listening to it at 1/4 volume (pretty quiet).
BTW- I've got the (stock) premimum sound system that comes with the 2LT.
