I have a JL 500/1 amp for sale. I have had it for over a year but never installed it. It was working when it was pulled from the last car and I know it still powers up but I have not tested it since I got it. I will sell it as is unless I can find a way to test it. I will make this happen if someone is truly interested but not willing to risk it. Cosmetically it is in pretty good condition but at one point in its life it was in a TT that was wrecked and it managed to chip off a corner of the heatsink. This is only the side plate that is broken though and you may be able to get a new plate from JL. I know this amp powers on but I do not have a subwoofer to hook it up to and that is why I never installed it. At this point I have decided I am happy with my Bose system so I will not be needing it. I am asking $200 obo plus shipping. Pics when I get home.
