I've jammed amps into a few oddball items now, but this one takes the cake. This was an old dashboard heater. 1 watt circuit using a LM386N-4 op amp chip. Volume and gain. Custom lighting. It kind of sounds too bright though as the shell is plastic. Any suggestions on the best material I could use inside it to dampen and take some of the highs out of it?

Yeah it was aftermarket. It was powered by the cigarette lighter. I'm guessing it's at least from the 80's. No marking on it anywhere to indicate who or when it was made...not even a ULC/CSA stamp on it. I found it at a flea market for 5$
