JL Audio 500/1 Help

[w0lv3121n3 10+ year member]

I have a JL Audio 500/1 Amp connected to JL Audio 12W6v2 but gives only small sound.

Worked perfectly but all of a sudden became weak ( didn't change anything ).

Everything powers on ( does not go into thermal or low ) but I get very small sound from the amp.

I have checked all my wires.

Checked my settings and gains too.

I currently am running a different amp and works perfectly fine.

Any ideas on whats wrong with the amp?

Thanks

Is your gain set right?

 

[w0lv3121n3 10+ year member]

ya, checked and rechecked.

did you switch any of the slider buttons around? like infrasonic filter etc...

 

[JLa Obsessed 10+ year member]

or maybe you switched your input voltage from high to low???

 

[w0lv3121n3 10+ year member]

The infrasonic is set on off

and the voltage is set on low, if placed on high, it gets even weaker ( Almost none )

might wanna open it up carefully and see if anything is burnt

I opened it up.

No sign or smell of burn.

Any ideas?

Is my channel blown or something?

How much could I sell the amp for?

Everything power on and works but just weak output.

that's really weird...have you double checked your sub wires by taking the sub out of the box??

 

[w0lv3121n3 10+ year member]

Ya

Currently I am running the sub with a different amp ( Kenwood ) and it works perfectly fine ( Same wiring setup ).
