Re: how to repair a blown sub

If the wires just disconnected, you could probably get some glue and glue it where it was originally.

I had my boss 2400 watt 2 channel amp hooked up in my car. I had one sub on each channel and one of my subs blew. I unhooked the positive speaker wire on the blown sub, everything was fine. Driving down...

If your amp started smoking, probably not. Due to your description, did the other sub really blow? I would hook it up to another amp to test it. It may have been a channel in your amp. As for repairing the amp, the parts and labor to repair will probably cost you more that to just replace the amp.

your subs are probably blown, or have a blown voice-coil. push on them when they are of and see if you can hear a scatchy noise like wires scraping. if you do they are blown. get back to me

Sub blown

As an authorized dealer - i can tell you that kicker WILL NOT repair any subwoofer that is out of warranty.
They use a proprietary cone assembly and do not sell it to ANYONE to make repairs.
Unless you know someone that works there personally - you have a doorstop on your hands.
I have a dead L712 in the shop if you would like matching doorstops :D
Sorry to be the bearer of bad news!

SPL160's with 2 blown voice coils

Downgrade to two subs.

The simple fact of the matter is these are long out of production. Nobody can get you a replacement coils/spiders at this point.

The sub could be rebuilt, but it could only be ran by itself. It would be a different sub all together and couldnt be run with the counterparts.

Bad solution for you but the only viable one.

Blown subs

My big question would be "Did your friend know the subs were dead when he gave/sold them to you?" If so, he needs a swift kick in the ***.......But onto your question.

If the cone doesn't move at all, or there's a scratching sound when it moves, you've definitely have problems. I have no firsthand experience with speaker repair, but I do know it exists. A quick Google search for "speaker repair" can give you some ideas for places to ask. Keep in mind, most of the speakers that get repaired are those that are discontinued, classic, or otherwise expensive enough to make the repairing of it a better option than replacing it. In your case, it may be the same price to repair it as it is to replace it.
