you could solder the wire back to the terminal..
i dont really know much about this but im sure one of the golds on here could explain it

Yes, you can re-solder the broken connection to a given coil lead with the right tools and a delicate touch.
However, if the enclosure is a bit too large and excursion of that cone is too great, you've only fixed the symptom, but maybe not the cause.
1. Box is too large
2. The damaged woofer is not up to specs (Or defective)
3. The power amp used is not matched to the subs power ratings
4. Too much Bass Boost is used on your amp
Say more please,

the box subs and amp were given to me free the subs are 12" MA audio 600watts the amp is audiobahn a8000t and the box...that appears to be homemade in a configuration i havent seen before, it is a rectangler prism shape 37"X14.5"X15.75" one of the subs is on the end plane that is 14.5x15.75, the other is on one of the long plane that is 37x15.75. the box is ported but, not by holes and sleeves just by rectangler opening on the 37x15.75 plane opposit the sub. but aside from what appears to be the big problem how should i repair my sub with the broken lead? i wonder if i can teach myself to solder

Sure, if the lead separated at the termination lug, that's a doable repair with minimal skills.
If the lead wire broke under the dust cap and joined to the voice coil, this is a very difficult repair and not likely to hold very long either.
Learning to solder properly is more about learning the basics and practice until you get the right results consistantly. The main tricks are:
1. Proper heat range of the soldering tool used (35 watts is typical)
2. Clean surfaces to work with (IPA, rubbing alcohol works well)
3. Use rosin core, 60/40 electrical grade soldering wire
4. Use a clean soldering tip and pre-tin with solder for best results
5. Heat the surfaces adequately before applying solder
6. After soldering, check the color of the solder joint (we want a shiney and tight shaped drop... not a grainy blob)
Finally, do a google search for videos on how to solder electrical components and then practice the techniques until you get the hang of it.
Good luck,
Swez
