Yes, the coil's copper wire is broken and making connection just "by chance luck" of being close in proximity. I have actually soldered these breaks, and yes your's can be soldered if the break is clearly visible after sufficient disassembly of coil area. Remember to use emory cloth near the break ends to remove the factory winding varnish and to "tin" the copper ends before they are soldered together. Finish with a good epoxy to bind the repair to eliminate "floating" which may re-break the wires.

Kickers dont beat like they should

try to check and clean the wiring as clean as possible to avoid messing up on your connection. Check the polarity of you subs to yuor amp if you have it connected on the outher way around it would not give you a good result. check the polarity this will solve your problem. Over powering your sub will fry it easily try to tune it a 10" sub wont give you a 15" performance..

Subs dont beat like they should

you've spent alot of money on **** by the sounds of it!!. you should only ever run multiple subs the same brand, power and resistance you can just connect any old subs to a system you need to wire them depending on the load that the amp needs to see. first thing is to try the amp/s on a individual sub to check your amps still work once done check the subs 1 by 1.

R-20 Sub stopped working.

might be a loose connection in the jack terminal. Sometimes pulling it in and out several times might free dirt or oxidation in the metal contacts. A contact cleaner is handy with this. Check also the wires for continuity. hope this helps..

Pioneer xv-dv424 power problem?

Try disconnecting all the speakers and turn it on. If it stays on, then a speaker (most likely sub) is gone and shorted, causing the system to shut down to prevent it from being damaged. Hooking up one at a time and powering on should help you find the bad one. If it still shuts down with all speakers disconnected, then you've got internal problems with the system itself. Time to visit a repair man.

Hope this helps, and please rate my advice, good OR bad.

Good luck!

TEAC - CD-X9 - No sound in left speaker

the speaker wire itself could be grounding out. look for small knicks in the wire and make sure the plug is not faulty. RCA plugs can go bad which would account for intermitent troubles some times
