This can be a faulty ground or speaker wires running to close to other wires from the car. You can also buy a filter for the speaker wires.

JL 300/V2 shuts down

you may have a weak power supply, check for proper ground ( clean contacts with a tight bolt to chassis), or too low speaker impedance because too many speakers or shorted speakers or leads to ground.

Blown fuse

What size fuse are you using?

Have you checked the speaker to determine if it's damaged?

Do the speaker and amp produce clean sound up to the point where the fuse blows?

Scratchy single channel on amp

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!

This is no joke man, I did this just yesterday and was really excited to save 190 bucks. I'm not a technical guy or anything all I know is the green things are located behind the out puts inside the amp.

Amp cell went bad!!!

You may be able to find a local shop that can repair it. If you want to send it to JL for service, you'll have to go through an authorized dealer.

JL audio Low ohms indication

If the low impedance light is coming on, you may have shorted wiring or a defective speaker. Disconnect all of the speaker wires from the amp. If the light does not come on, reconnect one speaker at a time to see if you can find the one causing the problem. If the first one you connect causes the problem try a second one. If the light comes on with no speakers connected to the amplifier, the amplifier is in need of repair.
