Either the sub woofer speaker or the sub woofer amplifier section circuit has the fault. Contact any service technician to make diagnosis the faulty section. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

Hi,sorry but you can not connect it directly like other sub-woofers.. Bose 2683 Powered Subwoofer is part of Bose Lifestyle 5 system, Please note that
you will need the 5-pin DIN cable that connects the subwoofer to the
base or "Music Center". and the 4 pronged connections for its own stereo speaker output not input from another stereo.. Sorry....but if you can arrange some handy man nearby ,he may get into the DIN cable to locate the subwoofer signal 2x input leads than you can use that leads for connecting into single sub woofer out let of your system...otherwise try to sell BOSE which can easily buy brand new up to date powered sub.. . Take care and please Remember to rate/vote and give me 4 Thumbs Up for Helping out the Community :) Hope this helps!
You can connect the two 6x9 speakers to the two individual left and right outputs of the car stereo.
Connect each of the left and right channel with the correct polarity . Now the Sub-woofer requires an amplifier to be connected separately and so you need to use the car stereo to be linked to a sub woofer amp which powers the sub woofer.
First you need to determine what kind of subwoofer it is and by that i mean, is it a dual voice coil subwoofer or a single voice coil sub woofer.
Dual voice coil(DVC)
Depending on how many Ohms each voice coil is you will have the amplifier drive a specific load (4OHM stereo (75 RMS x 2) 150RMS total power / 2OHM stereo(100RMS x 2) 200RMS total power) Connect each voice coils separatley to each speaker output of the amplifier for this configaration. Always making sure that the + & - of each voice coil go to the coresponding location of the speaker outputs of your amplifier.
If your sub woofer is a single 4OHM voice coil then your cables should be connected to the coresponding location on your amplifier which states "BRIDGED" It is marked clearly on the speaker outputs of your amplfier.
If it is a 2OHM then do not connect it to the amplifier. The specific amplifier is not stable at 2OHMS bridged and will most likely get damaged if you try to operate it at that OHM load.
On the side of the amplifier where the adjustments are there is a switch that indicates X-OVER. (LPF/HPF/FULL) Make sure to set it to LPF (Low Pass Filter). (not doing so can damage the subwoofer)
On the left hand side of the X-OVER there is the adjustment for the LPF (30-250) the best setting would be at the same frequency that your speakers stop
If your speakers have a frequency response of 60Hz to 20KHz then setting your LPF to roughly 70 to 80 will be ideal. The rule is that where one speaker drivers frequency ends, the other must continue in order to complete the full range of audible frequencies.
if you have any more questions feel free to ask.
if ur amplifier have a pre out, then u can connect that to ur L/R input of ur sub woofer.
if not the only way is, connect ur amplifiers speaker output to sub woofers speaker input and then connect ur speaker to sub woofer speaker output terminal. remember don't inter change positive and negative wires.
if ur amplifier have speaker A,B connection then it is very easy. connect the speaker A to ur left and right speaker. then connect speaker B to ur sub woofer's left and right speaker input. be sure to make that speaker A and B switch is in on position. the power on both and check it. ( use good quality speaker cable to connect the sub woofer)
your sub woofer is designed to work , both at low level and high level input.
I just finished repairing one of my VR960 units with a similar problem. My problem was that the sub would crackle no matter what input level. After changing a few of the active components, I finally discovered it to be a capacitor which was faulty. Anyway, I replaced the three 100uf 25V capacitors on the main board and all was well.
The gain dial is not a volume control. The gain dial is used to compensate the output level of your car radio head unit. all car stereo units output are not alike. If you set this gain level too high, it will cause major distortion (clipping) to the audio output of you speakers when cranked up. This excessive distortion WILL eventually, or even quickly damage or blow your speakers.
I personally blown speakers this way no not properly setting this. (lesson learned, I guess :| )
The amplifier probably has a built in protection circuit to keep from over driving the subwoofers. This will prevent the dealer from replacing woofers........most likely it's designed to be overly safe. There's likely not much you can do about it, if there's not enough bass you may have to seek out a larger amplifier.
