    ok, the amp i do not kow for sure all for brands is that it says XTreme along with the subwoofer and XScorpian, the amp had a number xa-3002, and its a 300 wat amp, i do know it isnt blown out, it is a dual channel, the amp is attached to the rear of the woofer box, along with all the wires running through the seats(wires are fine, damage wise as far as i can see).

    there are 2 wires there is only one speaker, and they r in the corect places, to fix this do i need to buy new wires?

  • letsallskate May 15, 2009

    there are two input kind of wires one is red the other is grey they r in the two plugs they r supossed to eb all the wires are there, except one was missisng from a spot i belive it says 12v above it and it has a copper end and you need to screw a screw to hold it in place sparked last night while i was putting it back on, and there is no sound at all.

    are the ends of the wires bare copper? or do they have some kind of connector? If they're bare wire, make sure that not a single stray copper wire is touching any part of the other terminal. What do you mean by "they are in the correct places"? Are they in speaker output 1 or 2? Are the two wires connected to the correct corresponding + and - terminals. Are the wires connected to single terminals on different outputs? For example, one wire goes to the + terminal of output-1, and the other wire goes to the - terminal of output-2? On many amps, this configuration would be called bridging, but not all amps can do this. Is your amp hooked up this way? has it ever been? If you attempt to bridge an amp that isn't bridgeable, it's possible to fry the power supplies inside the amp. If you gently push on the cone of the woofer, do you hear any kind of scratching or rubbing sound?

    Ok, the amp you have is a 2 channel amp (2x55W@4ohms). On the side of the amp where the speaker wires are connected, there should be two speaker outputs, each output consisting of a positive ( + ) terminal and a negative ( - ) terminal. You should have a total of 4 speaker connections (2 per speaker). Please tell me how many wires are connected to the speaker outputs, and which position they're in. I'm guessing that you have a short in your wiring somewhere, and the amp is going into short-protection mode as soon as it turns on.

    Hey there, I'm going to need more information before we can start troubleshooting for a resolution. What brand/model of woofer do you have? Is it a single voice coil or dual? What kind of amp do you have, and how is the woofer connected to it? The more information you can provide, the better.

Ok, that was some important information there. If you were tightening the 12V power line, small sparks are normal. You should also have a thin wire (often blue) going into a 3rd terminal. This is normally called the remote wire. It's the wire that tells the amp to turn on when your radio turns on. Do you have a remote wire connected? When you start your radio or car, does the amp light up? There should be a power indicator light -does it light up? There may also be a fuse on the side of the amp, pull this out and see if it's blown. If not, put it back in.

Protect Light On Amp Being Weird

Could try switching right and left subs. If the problem moves to the other side pull the wiring and redo.
Then if the wiring is ok check the sub.

Box size and airspace for 10 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 10 inch <span>Sub woofer</span> ranging between 80Hz and 100Hz, the ample box size required should be around 26 liters, meaning that you will end up with a box of 11 inches high, x 11 inches wide, x 11 inches deep. <br />Enjoy! <br />

Bxr1121 woofer not working connections seem to be ok. satellites speakers ok. headphones ok. no break or shorts to be found.took speaker out checked wiring inside no apparent shorts. is there an...

if you hook one of the other speakers to the wire for the woofer does the speaker work?

if so it is bad woofer

if not wiring is no good

there might be a circuit breaker that you push in on the on off switch or in other place

make sure if you are using speaker level connection that you are putting it in right place

it should be a line level input if this is a powered sub woofer

also there might be a volume control on sub also

be more specific on connections and where they are coming from if you need more help next time

good luck

My sub woofer stopped working, please tell me where it is located so i can check the speaker and also check if power is going to it thank you very much joe

The JBL premium sound system has a large woofer in the bottom of each door, a small mid-range speaker next to the woofer, & tweeters next to the front door windows in the corner, & two full-range speakers near the rear seats. The woofer (not sub-woofer) handles all the low end. You can test the woofer by turning the BASS to max and TREBLE to minimum (make sure balance and fader are centered) and put your ear next to each woofer.
The woofer is usually the 1st speaker to have problems after 10 years or so. The outer edge of the woofer starts to degrade. You will usually hear a rattling sound out of the woofer when this happens.
NOTE: If no sound at all out of the woofer (tweeters are OK), you might take your car into a car stereo shop. They can put a speaker on the wires connected to the speaker and make sure your problem is not the radio.
PROBLEM: You can still hear sound out of the woofers but it is distorted
SOLUTION 1: Go to a car audio shop and have them install new woofers. These may cost $30+ each but the dealer cost is over $200 for each woofer (crazy).
SOLUTION 2: More involved but very cost effective. If you or a friend is handy, you can go to and order a new set of speaker outer rings (on the site they are called speaker SURROUND) that will replace the damaged outer rings on the woofers (replace on both woofers). They really work great and your speakers should last for many more years.
Hope this helps.

Could be Faulty RCA wires (they bring the sound from the radio to the amp) or a bad ground (the larger black wire coming out of the amp) This is under warrranty and you should not have to worry about it... bring it back, they make fix..

Most amplified sub woofers need to be grounded to the output source.If you plug the sub woofer in to the receiver you would use a ground wire from the receiver to the sub woofer there should be a ground terminal on the sub woofer and receiver.
