X-220 cable is slightly damaged and not making constant contact with sub-woofer mate. Is there a repair where I can replace or cut open & fix the 9 pin cable? To me, the obvious problem is that the cable pin is damaged internally. I don't think anything is wrong with the sub-woofer mate.

Contact the seller and the shipper and have it replaced. You wont be happy unless you do. You will always wonder about sound quality.

Sub woofers have small amplifiers , not transformers. The amplifier is removable and replaceable. The The overall size and the output wattage are the spec's you need . The output wattage is on the label which is attached somewhere on the speaker. You do NOT need to replace the amp with the Altec Lansing brand. Have you contacted Altec Lansing to purchase a replacement Amp? That's where I would start. If they cannot help you I would Google replacement amp sub-woofer, Altec Lansing model MX5021.
good luck

sub woofers are very powerful bass , with incredible sounding technology. your problem might be with the woofer wall around the circle. open the box and take the woofer out.Check if there is any tare over the corners of the cloth. sometimes there might be a crazy noise because of a little opening in the cloth caused by small tare.. if so better change it with a new 1 and make sure that the new cloth has guaranty
damaged sub woofer eg. torn cloth-
Thanks for rating good luck

Any radio shack or best buy will have a new sub woofer cord, should not run you more than $ 15-20

yes, you can splice the cables and put on a new connector, goto radio shack with the old connector and im sure they will have one you can splice right onto it. ive done this many times with varios equipment "headphones speakers etc" it may take a couple of tries to get the wiring right but if its just one speaker there will most likely be just 2 wires, if you wire it up and it doesnt quite sound right, wire it the other way. speakers will work wired backwards but wont sound quit right so if it doesnt, rewire it and it should. good luck and i hope this helps!

there is an electronic part that needs replacing here..As far as I remember this is common with a faulty condensator...or the transformer itself..there are some ways to fix this but you will need the right tools & expertise.

is it the car vibrating or the sub making the noise ? if its the sub making the noise check all the screws holding in the sub and make sure they are tight or make sure nothing got sucked into your box if it is the car making the noise try using dyna mat to help stop the noise also check the surround on the sub and make sure there is no seperation of the surround from the cone

if the amp is going bad repair or replace, the sub you would probably have to replace, this would be the best fix. but check the amp also.good-luck!

The sub contains the amp for the other speakers. But it sounds like the amp has a seriously damaged section and will probably have to be serviced by Bose.
