Question about Jl Audio 12W3 Car Subwoofer

1 Answer

Could a ground stop your woofer from working?

My whole system is hook up right and it sounds very clean until, the subs just shuts off. All my high are still working fine, but my woofer, just shuts off. The fuse of the amp is not dead, the amp itself it's on green, it doesn't smell like it's burn, the woofer itself is not burn. The amp is on, but it seems like no power is coming from the amp to the woofer, cause i tried another woofer to the amp and it did not work. Could it be the ground for the amp or other line for the amp is not working or whatever it is that is not hooking right that made my woofer died.

First check the speaker wire from the amp to the sub, see if it's connected right. Second check the rca cables that goes from your amp to the back of the deck. I f both wires are still connected fine try to replace the rca cables. If it still doesn't work the rear out put at the back of your deck, where the rca's are connected are bad. FYI deck is bad.

I want to install a self powered woofer and tap it to the rear speakers. Can you please tell me what are the colors and polarity of the rear speaker wires for 2006 Honda odyssey right hand drive


FIRST OF ALL --- THERE IS A FEW THINGS YOU NEED TO KNOW BEFORE HOOKING UP
A WOOFER LIKE THIS ---- IS THIS A STORE BOUGHT POWERED SUB WOOFER ? DOES IT HAVE IT'S OWN CROSSOVER BUILT INSIDE ?? I WOULD GUESS IT NEEDS TO BE HOOKED
UP TO A SUB WOOFER OUTPUT FOUND ON THE BACK OF THE IN DASH PLAYER ..
THE WOOFER NEEDS TO RECEIVE ONLY LOW FREQUENCY AUDIO WHICH MOST OF THE NEWER CAR STEREOS PROVIDE BY AN RCA JACK ON A SHORT WIRE COMING OUT OF THE STEREO ...
IF YOU TRY AND TAP IT TO FULL RANGE SPEAKERS THAT ALREADY ARE CONNECTED TO AN AMPLIFIED SIGNAL THE SOUND WILL BE DISTORTED .......
POWERED SUB WOOFERS NEED A LINE LEVEL INPUT WHICH IS MUCH LOWER THAN SAY
SPEAKERS ALREADY RECEIVING AN AMPLIFIED SIGNAL.
POWERED WOOFER WILL ALSO NEED TO HAVE A 12 VOLT ELECTRICAL CONNECTION AND A GROUND WIRE TO OPERATE THE AMPLIFIER BUILT INSIDE.
IF YOU HAVE NO EXPERIENCE WITH THIS TYPE OF HOOK UP I WOULD STRONGLY RECOMMEND SOMEONE WHO DOES [ CAR AUDIO SHOP ]

Box specs and airspace for 8 inch subwoofers


<span>Regardless of your wattage rating on your sub woofer, sub woofers</span> differ in only one way. You get an "Open Air" and a "Closed air" <span>Sub woofer</span>, That being said, you'll have to check on your magnet which one you have, to make the boxes for that particular sub woofer. If it is an "Open air" <span>Sub woofer</span>, you should see a hole with "wire mesh" or "metal grid" in the center, at the back of the magnet. If it is a "Closed air", the magnet will be solid with no hole whatsoever.<br /><br />If it is a "Open air" sub, your boxes should always be sealed with silicone sealant, and no ports are to be cut in your box.<br /><br />Regarding the "Closed air" <span>sub woofers</span>, you should have 2 ports cot in the corners of the boxes just below your sub on the face of the box, and the port sizes should be around 50mm in diameter. Get yourself some 50mm PVC drain piping to use as ports. Firstlycut yourself a 100mm piece and insert flush with the front of the box. Test your sound. then try a 150mm piecs and test again. You should start with a 100mm long piece in the one box and add 50mm increments to "tune" the port up to 250mm, depending on the frequency of bass you require. Carry on testing the sound on each increment until you find the sound you want, Then silicone the port to the box for permanent fixing.<br /><br />On a 15 inch <span>Sub woofer</span> ranging between 80Hz and 100Hz, the ample box size required should be a box of 9 inches high, x 9 inches wide, x 9 inches deep. Or 400mm high, x 400mm wide, x 400mm deep. <br />Enjoy! <br />

What settings to put on Rockford fosgate Prime 250.1? one P1 12 4 Rockford Fosgate speaker, in atrend LSV 12 vented box. With JVC radio that has the sub woof, MID. What is MID and what setting to put it...


Need to know what JVC deck you are referring to so I can give you optimal settings. Mid is the mid-range of frequencies... ones that are sent to your door speakers' woofers, not the sub-woofer. So set that to whatever you feel sounds best, probably low in my opinion. Subwoofer set it as loud as you want, it depends on what kind of music you listen to. If you want your bass to be "boomy" then set it high. If you want it tight and crisp set it low.

Auto adj is auto adjustment for when you turn the sound louder it increases all settings accordingly. I always recommend putting that on 5 so if you ever want to crank it - the whole system gets cranked.

Thanks, let me know if you have any questions or concerns, just reply to my answer here and I will be right back with you.

Car system sounds like ****


It sounds like your speakers are out of phase. Check very carefully the polarity is the same on both speakers (at both ends). That'll certainly get you sounding better.

If my woofers at bridged and my and is too but it


first you dont bridge both ,, 2nd you will need to find out what ohms your speakers are , and if dual coil what ohms each coil is ,, then find out what ohms your amp runs at , at full power.. then try to match your subs to the same ohm load,, REMEMBER there are diff ways onto how to hook subs on which will change the ohms.. good example 1 dual coil sub each coil is 2 ohms then you can hit a 1 ohm or 4,, depending how you hook them up .. When adding more subs and how you hook them up changes the whole game.. if your not sure on how to hook them up read a manual or go to a local shop you can burn your subs up or worst the amp if hooked up incorrectly ..

Sub woofer


are your subs bridged? if they are try unbridging them... if that doesnt work try finding a better ground, and if neither of those work turn the amp down while music is playing until the palsating stops and the speakers are just hitting...

Do you know if my woofer is blown?


well if you hear a rattle sound its probably already blown...and the amp could be drawing too much power if the radio shuts off...make sure all your wiring is correct. also if your car is off and you turn it up it will most likely shut off cause the battery cant handle it. but as for the sub i think its blown. good luck
