I have a JL 500/1 Amp that kinda doesnt work anymore. I think when I had a leak in my trunk some water got on my amp and somehow got inside. All I know is I took off the metal cover and there is a little bit of white residue on teh board and it no longer works. Would anyone want to help me out, I dont know what to do. Its a $575 amp and I used it less than a year. If possuble I would be willing to sell it for $300 and if you want to try to fix it or have someone get it fixed. I dont want to bother with that. Thanks, let me know.
