3. Description/Condition: Mechanically 8/10: One output lug is stripped, easy fix which I can do or you can do, simply tap it to the next size up.

Cosmetically 8.5/10: The clear plexi panel under the amp is bowed on one end and the plastic housing for the speaker lugs has a small crack in it, not a break, just a crack and the black chrome on the ends is blotchy looking, the heatsink has a ding in one spot that's mostly hidden.

Electrically 9/10: It doesn't like being in a trunk on hot days. It'll function perfectly for an hour or better then shut down from thermal overload. If it is in a cool environment it does great.


4. Price: $200 shipped/insured

Depending upon what it is I'd consider a trade but I don't need subs, amps or coaxial speakers. That leaves comps, EQ/crossover combos & heads... on the latter it needs to have at least 4V pre-amp outs (6ch), onboard crossovers and a USB input.

when you say the plexi is bowed on one end, im trying to see what you mean by the photos but cant really tell..
but do you mean its pretty much caved in on one side? also the output set that is stripped are you talking about the head or the side wall that threads the screw?
haha thanks

Look at the last pic, you can see the bow on the plexi at the daughter board.

Back up for sale and I'm going to fix the speaker lug Tuesday.

Edit: Speaker lug is fixed.
