I have a Jl audio 300/4 amp and it recently started making a weird fuzzy static like noise. I have checked all wiring and concluded that it must be something internal. I have no idea what could cause it. PLEASE HELP!!!!
I had the same problem with my 500/1 and was even told by a Radio shop that I should just get a new one. WRONG! Open up the back of your amplifier while you have your system on and look for a loose circuit (white rectangle half visible on my 500/1) it probably came loose and is bumping against what it is usually connected to. I used a pencil eraser and stuck it between a circuit board and this circuit to keep it stable. Amp works great now, but it can come loose.
If you unhook the rca's does it persist?
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!

same thing. Everything was fine . listening to the stereo. Then all of a sudden distortion heavy over all channels like a chaffed wire or something. checked everything removed amp rechecked with test speakers same thing. if i smack it with my hand closer to the side with the power input it will clear up for short time like until i sit down and raise the volume
intermitent static sound can be heard on front two channels. Teh static sound may last for few hours and after this it will be OK. Appears to get worse (happens more frequently now) over sevral months. The amp is about 5 years old. If the right channel input (RCA) is removed than the static sound problem is gone. Swapping the left and rigght channel input does not make any diffrence.
the front channel on my jl 300/4 amp gave me the same kind of fuzzy sound but only once in a while. at first i seemed to have fixed the problem by bridging that side but after a while, that started doing the same thing. now it's constantly there. i know its not my wiring cause i moved all my wiring to the rear channel and it sounds fine. anyone know whats wrong
