JL 12W2 Subwoofer

The Subwoofer works when the speaker is pushed in by hand but when you let the sub go it works for about 5 seconds and quits again until you push it back in.

Happened to me, i also had a metallic/iron smell coming from my sub... i pronounced it dead. had to buy a new one and it worked fine... if you believe its not dead then your amp is not getting enough power and most likely shutting off (protection mode), you can try buying a cap, farad 2 or better will work and is suggested for larger subs anyways

I have creative 2.1 channel with sub woofer and 2 speakers (left&right) all of sudden my right speaker is not working left only working then I pluggeg right speaker to left speaker jack in sub...


I have a similar reoccuring problem with the left channel on my speakers. All of a sudden, while playing music or whatever, the left channel jusr dies. Turning the system off and then on again from the conrol unit does not remedy the situation. By chance, I discovered a workaround to get the left channel working again: Push the main power switch of the subwoofer until it almost switches off and then release it so that the power is never actually switched off. Now a click is heard in the system and the left channel comes alive again. This is quite annoying and seems to have something to do with switches in the subwoofer. Low quality components may have been used. I 've been thinking of getting another 2.1 system, but it's not easy to find one... Maybe I should open the subwoofer box and go through the switches and possibly hardwire some connections...

One sub not working


Try this....the speaker that is not working, gently work the cone up and down with you fingers. Be careful not to go right thru the cone. One hand underneath(near webbing) and one hand on top over the dust cover. If you hear any kind of scratching, or noise, or it's not "breathing" freely, then the voice coil of that speaker may have overheated, or the speaker has extended above and beyond its range of movement (called excursion). And may as well be blown/dead/fried..however you want to say. I hope this is not the case for you.

I wonder if i get two kicker cvx 10 can be push by jl audio 500.1


It can but it'd be a waste for your subs. 1 of those by itself will handle that amp. it'll push them just not really hard, i'd recommend an upgrade to a 1100-1200 watt rms amp if you're gonna run 2 cvx's. if you only run one sub that amp'll work well...

Subwoofer buldging out problem


When speakers are wired in the wrong way the will do the "pushing out" you're describing. Basically the polarities have been reversed and if kept like this over a period of time will blow the speaker. Best thing to do is to disconnect the power by the negative on the amp and take out the fuse from the power supply. Check the wires running from the amp to the subs, negative to negative and positive to positive. I know it sounds basic but many people do mix it up! I would also check to see what channels the subs have been wired into?

Best way is to have one sub from channel 1 and the other sub from channel 2 for example. Or if its a bridged 4 channel amp, have 1 sub running from channel 1&2, and the second sub running from channel 3&4 still making sure of the polarities. Again this all depending what kind of amp and sub you have.

-----------------------------
For example;
A 4 channel (bridged) 1000W amp. 250W max per channel or 500W per 2 channels! So if you have 2 500W subs, by connecting one to a single channel will decrease subs ability due to the lack of power supplied. However by combining 2 channels you optimize the output!
---------------------------

Once you know all your wiring from your amp to subs are ok/good connections/good wires etc you shouldnt have to "wiggle the wires" to get it to work as this is just a bad connection. Also ensure that no 2 wires are touching. Make sure that the master volume on the amp is turned down. You dont need this to be on loud at all, in fact far from it or you'll risk damaging both the amp and subs!

Hope this helps!

Subwoofer pushing out problem


it sounds like one channel in your amp had shorted and letting dc go to the speaker...a speaker is an electromagnet and requires ac to make it pulse..the amp has a blown channel and would have to be repaired and a factory service center...there is no quick fix..
