Well I had my JL 500/1 Hook up to a L5 15" for about 6 months now without a problem till now. When I crank up my bass my sub turns off but my amp is still on but the LOW amber light comes on. but it takes a real long time for it to turn back on it took 1 day for it to come on ? That day I was trying it every hour with no luck until the next day, Its a very werid problem I would like some help on this ? Stereo shops here said its the amp, then the other one said its the woofer, and said it needs a cap.
