85WPC automotive stereo amplifier - $30 (EVERETT)

We installed this in our RV to bolster the wimpy sound system it came with.
The RV is now gone and this can be used by someone else.
It was working great when it came out of the RV 2 years ago.
It's not a huge power modern digital amp but a good sounding Class AB amp.
It puts out about 80W per channel in stereo @4 ohms or you can double that in a single channel bridged mode.
It takes either speaker level or line level (RCA) inputs.
After blowing the dust off it appears in nearly new condition.
The manual is available on-line.
