SOURCE: bad amplifier need help!!!!
I had the same amp! It is the JL 300/4 and one of the chanels came in really fuzzy. It sounded as if the the wires were touching during my installation. I called JL and a JL authorized dealer it would have costed me 190 dollars total to get the amp fixed. Instead I opened up the amp to see if anything looked out of the ordinary. When you open the amp, see if the green fuse looking things are aligned. If they are not aligned then straighten them out. I think they had gotten out of place from being dropped becaue I baught my amp used. My amp works perfectly now!

Best bet is to send it back to JL, they do not sell the PCB with all of the components loaded on it. Most likely the transistors in the power supply have fried. Open it up and see if you can find any physical damage. Google the part numbers of the bad parts, and you should be able to fix it relatively easily. www.digikey.com is a great place for parts. Read this for more testing procedure: http://www.bcae1.com/ampfail.htm The whole site is wonderful, really.

if its cutting off and right back on then check your ground and your power wire makes sure both are connected good and none of your fuse's are blown, either that or you got a wire hooked up backwards in the sub.. but my guess is that the sub is hooked up wrong... that sub should be hooked up in a series or in parallel,
ok if your running just one speaker, it should be hooked up like this and 2 speakers are a different way...
this is parallel :pos to pos , neg to neg, then one wire coming from pos on sub to pos on amp then neg on sub to neg on amp but bridge the amp on your amp should be 2 pos and 2 neg in two different channels take the pos off the sub into the pos on 1 channel and then the neg from sub to the neg on the other channel,
this is series : on the sub it will go pos to neg then the other neg and pos will go to the amp, but make sure the pos and neg r on different sides of the sub, dont hook them both to the same coil
if your need more help give me your email and ill send you a pic of how to do it...

you may have burned the channel you were using..try taking the cover off the amp and checkin for burned spots or any wires that may be loose or touching within the amp.
