I have a jl audio 250/1, bought it used. Guy before me had it on 2 12 inch w0's I believe. Anyway, I had it on a 10 inch memphis audio (m2), 400rms 800max, sub. After about 2 weeks, the sub just stopped hitting. Besides the the sub being a piece of sh1t I was wondering why the amp would power on, but no music was going to the sub. I hooked it up to several other subs, and still would not play. Someone told me the output was burned out. Any suggestions, the green power light is still on. Don't really care too much for the amp, but I just wanted to figure out what was wrong with it. Thanks for any help.
