JL Amp isn't powering subs and speakers

I have a jl 500/1 Amp powering a jl stealth box with 2 10's....and speakers...worked fine for years. Battery to the car died got it replaced by Sears now I can hear music from all speakers but its not powerful - like the amp isn't powering them just the Alpine head unit. Any suggestions? Blown Fuse? On the amp or the relay to the battery?

SOURCE: JL Amp isn't powering subs and speakers

silly as it sounds, you may want to check your EQ settings on your headunit. Things like sub volume, SLA, loudness and balance. When they replaced your battery, those old settings were lost.

Popping sound! please help - jl 500/1 and two jl w3v3 2ohm subs


no connection are good + to + -to - thats all that matters. either the speakers are blown or you need a stronger amp. since you already tried speakers probably need bigger amp. definitley not the box. no such thing as a break in period, are the subs 10 12 inch or what. you could try to bridge them too that means hook both up to the same +-terminals, 2 wires per screw. it usually isnt the way they hook them up, its the wires fuses etc that cause problems. what guage wires is the speaker wire, the power line etc. if you give me these guages i might be able to get somewere

500/1 sub amp stopped working, burnt rubber smell


It sounds like the power supply failed. Generally when the supply fails in that amp, you have to replace all 8 of the power supply FETs and all 8 of the 47 ohm surface mount resistors. Many times, the supply fails because one or two of the output transistors have failed.

If you want to have JL repair it, you MUST go through an authorized JL dealer.

If you have a good local repair shop, they should be able to repair it.

Let me know if you have any other questions.

My JL subs just dont beat like the ONES IVE HAD before as well as the ones my friends have had


sounds like they have your sub amp in mono but they put the speakers in series which totally cancels the benefit of running your amp in mono. you will probably be happier if you just hook the left speaker to left plus and minus and the right to right plus and minus. Cuz even though subs aren't directional they do pass some higher frequencies that are and that dilutes the stereo effect.

Blowing fuses


You will need to have the amp bench tested at full load to see if there is a pending problem. It will need to see with speaker loading resistors, how much current the amp is drawing and at different frequencies. if the amp checks out with the proper current, at the rated output, have the speaker checked out. Good Luck

500watts sounds about right to me,i wouldnt go any higher as you risk popping the sub and haveing a melt down in the coil section of the subwoofer.
