My impedance light is on and I have no speakers attached to the amp! Is this something you can reset or is the amp broken?

 

it's probably your power....have you check all the fuses?

 

No but I will...I thought the amp completely shut off when voltage drops below 10v. The amp was working fine for months and now just started this crap.

 

This set up was in my car and running fine for about six months. I noticed some distortion the other day and shut her off. I turned it back on and noticed the low imp light and figured one of my voice coils fired and the 2ohm load was triggering the light. I unhooked the sub and the light was still on. So then I decided to remove the other speakers as well and the light still didn't turn off. I was under the assumption that the light would turn off without any load.

 

Hook up any working speakers, maybe a pair of small home speakers you have laying around. See if the light goes out

 

Didn't work but thanks for the input. I hooked up the speaker both stereo and bridged. It was a 4ohm speaker. The power seems to be fine as well.

 

sounds like a broken amp then

 

I think you're right...The JL guy on another board confirmed.

"That usually means one of the output FETS is shorted... needs repair. Contact your dealer."

 

I have 3 JL amps with this very same problem.

 

i had that problem with one of my jl amps. it was fixed for free under warranty. hopefully you have your box with the warranty sticker still.

 

my jl is messed up too...i strongly believe. i am getting little to know midbass out of my components and coaxils and the speakers are new. they are distorting as well...i have to get this checked. for the record....JL SUCKS! this is my third jl amp that has not worked correctly.

 

yup, seen a few amps with this same issue...time to get it warranty repaired

on a side note though, most of the amps i saw witht his issue was bought from online...i am not sure if htat has anyhting to do with it...but just so you know, many online warehouses, to prevent manufactuers from tracking them, acutally open the amp up, and scrape off serial numbers or put new fake ones on...i am not sure if this has anyhting to do with these amps more likely to go...but opening things up all the time i personally dont think is the best thing to do...especailly when done perhaps by inexpeirneced hands...
