Get the amp checked at a repair center, if you had a short, it is possible that the amp may have been damaged. If you get the amp tested and it woks fine, then you know the problem is in the wiring or the speakers. First you must determain where the problem is. you could be chasing your tail for a long time if keep checking wiring and speakers but the problem is the amp. Best to eliminate the amp as a problem first if you are confident that you wired the amp properly.

Ok i have a jl500/1v2 amp with 2 w6v2 subs and i haveing a problem dont no if the amp is two much for the subs becouse i turn the amp to get more tump and the subs pop and the yellow light filkes so i turn...

its real simple. your under powered.

your W6s RMS at 500 watts EACH and your sending em 250RMS (half what they need)
The 'pop' your hearing is the failure to supply enough power to draw the cone back in time and collides with the next wave of sound.

prove it?
drive a single W6 with your 500/1 bridged.
i'll bet your pop goes away.

long term, get another 500/1 or jump up to a 1000/1v2.

I also HIGHLY recommend JL's in-line audio cleaner. If i recall it was like 60 bucks but waaaay worth it. makes sure that theres no distortion in the source input to your amp(s), which...keeps your subs from trying to reproduce transients and delivers only clear signal to your subs void of all clipping signals. Its an active electronic compoent.


PS: if you are pushing 12W6's, i had the same setup once...I had W3s connected to my 500/1 and upgraded to the W6s...had the same issue your describing, and then got the 1000/1. happy ending.

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.

Car amp's stopped working. Putting out a heart beat sound through subs but no bass.

could be low current ,disconnect all power including ground for 20min N.B most amps will seem to be shorted at output but this is normal due to damping ratio.
