Just as title says I am selling my kenwood 4 channel. Only catch is the amp does not power on and no output is put out. So it must be blown. I don't work on electronics so only thing I can tell you is that it does not work. It worked in the past sounded good, I took it out of my car put it away, I tried hooking it up a few days ago and nada, no light nothing. Asking $20 + shipping obo.
