I have a Kenwood Excelon CD/mp3/USB head unit. Bought it new couple months ago.

perfect shape I just bought a different more competition type deck.

The kenwood is in perfect shape I always use the remote. not a mark on it.

great deck. $150 shipped

I also have a new mono amp that is about 12x5x2 in size. does 500 x 1 @ 2ohms or 300 x 1 @ 4ohms. 60 amps worth of fuse so it probably does more than that. its class G/H so its efficient but sounds better than class D.

Same as a Arc Audio KS500.1 mini

new in box $125 shipped.
