Question about Jl Audio 12W3 Car Subwoofer

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

Hi,

Ok, so I recently purchased a new jl 500/1 and two jl w3v3 2ohm subs. I took it to the shop and they installed both subs for me. This is how they configured it.. http://www.geocities.com/diekronz/untitled.bmp - I used paint to create that image.. sorry if it looks "1st grade like".
Anyhow, he installed the subs in a standard dual sealed box.
THE PROBLEM: When I turn up the music, the subs begin to POP (one more so than the other). I went back to the store i had originally purchased the subs and they replaced them with another set - brand new, out of the box... and the pop continued once i turned the volume up on a song that had some decent bass. I originally thought it was the box.. but we replaced that too and it continued to pop.
I was reading up on ohms and how subs should be confingured to amp's and I'm guessing the guy just didn't install everything correctly. He basically told me that the subs have a 'break in period' and to not bump the music for a week until the subs are broken in properly. So, here I am, three days into having my system and I can't turn the volume up =/ I don't think the guys who installed my subs/amp knows what he's talking about.
I'm restless at this point.. Any ideas would be very helpful. Thank you for your responses in advance.

    Well i figured it out.. in a nutshell, my amp puts out 1.5-4ohms.. both of my subs put out 2ohms each.. when i connected both subs in parallel, they were giving 1ohm each at the amp. This was .5 below the acceptable tolerance. To solve the problem I had to connect my subs in series so I could get 4ohms. Its not getting the same amount of juice, but at least it resolved the popping issue.

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

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.

JL Audio 500/1 Amplifier "Thermal" light flashing


Re-check all the connections to the speakers, The uPC monitors all the outputs and if any are taking more power than they should, the uPC shuts the amp down to protect the internal components. Don`t use tape joints alone, try to run the cable the full length without any joints. If you do have to piece the wires together, solder them and stagger the connections, in other words, make one lead shorter than the other so that if the tape does come off, the offending connection is well away from the other so they can never meet or connect to each other.

Got jl300/2 amp confused which subwoofer sounds good


Hello drsubhakar26,

JL W6's will perform well with from 150-600 watts RMS. W7's with from 150-500 watts. Less expensive Alpine Type R's work OK with from 200-500 watts RMS. Either of the brands will sound good. None of them will perform to their full potential with 300 watts RMS. Powering any sub with a 2-channel amp is a compromise. A monoblock is more efficient.

Hope this helps.

Jl audio 1000/1 problems


Hello l_miller36,

Depending on how much you paid for the amp on eBay, and how well you like the JL product, it may very well be worth the money to get it fixed. As for the wallet damage, you'll have to ask JL or one of their dealers. But, since the Slash2's routinely sell for over $1,000, I'd estimate the cost to be pretty high.

First, I'd send an email to JL Audio tech support and see if they have a "flat-rate" repair option or if they can give you an estimate of the repair costs. My second option would be to talk to a local car audio shop that does component level repairs. In the first case, you'd get exact replacement parts and whatever warranty JL gives on repairs. Not so with the local option, but it would most likely be less expensive.

Hope this helps, good luck.

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.

Jl 500/1 no sound, green light


This is an indication that the MOSFETs are ok but the driver stages may have a problem. Get a schematic find the pre-amp stages and test the voltages levels there as compared to the schematic. I do believe that you will find the problem in the pre-driver pre-amp atages.
