I have a JL audio 250/1 mono amp that powers up fine and green light is lit.
The problem is that it won't send a signal to my sub. I hooked up my other amp and the sub works fine. Where is a good place to send the amp for testing and repair?

 

your gonna have to ship it back to JL most places wont work on them because it voids the warranty. If you bought it less than a yr ago its still under factory warranty and all you have to do is bring it back to a JL retailer and they can ship it off for you. The store i work at charges a 25 dollar shipping fee but JL covers the rest.

 

Thanks, I found a JL dealer that will send it in for me.
