Hi everyone, I have a JL Audio 500/1 that is blown. the green power light will come on, thats it; no safety light or anything. when it powers up the green light will come on but there is no output. Ive taken the boards out and looked them over. i have not noticed any visual problems but i could have missed something. does anyone know anything about these amps or how i can trouble shoot the problem! i live in Indianapolis, Indiana; if anyone lives close you can take a look. Thanks in advance. Eddie Gossett
