hey you guys i htink on of my 12in L7's blew. i was playing it for like 30 mins pretty hard and then it just stopped playing. the thing is i only had 300 watts rms going to it so it doesnt make much sense. also i didnt smell the coils burning or anythign and i push the cone and it moves just fine so im not sure what the deal is. also if it is blown can they be repaired? ive heard the have problems alot and somethign about the tinsel leads, thanks

Check to see if your amp is shutting off or going into protect when this happens- you may have your gain set too high. Is the amp hot?

If the amp is not cutting out, or going into protect, double check the wiring- it's possible there's a wire that came loose. If not, disconnect the sub from your amp, and try to ohm it out to test for continuity.

My ex once told me I have a perfect face for radio.

Check to see if your amp is in protect. Or if you blew a fuse.

interesting to see an l7 blow like that.....we have fed over 1500rms inot one and they keep kickin! I would check you amp, if that is fine, check you connections on the sub, something might have came lose. measure the coils with a Dmm to verify a blown coil

hrmm..that sounds like another buddy who came to the shop i used to work at...he had the pioneer 1000 watt amp (gm-510 or something like that) and had the new L7 in a prefab box and came back a week later with no bass...the coil seperated inside from the cone and stopped moving...but when you pushed on the cone, you never heard a thing. same as when your wired up another amp. put the meter on it and found out the coil was gone

First of all the 12" L7 can take 750w RMS continuously and 1500w MAX! You cant push any speaker and not blow it by underpowering it unless you keep the volume down. I hear these stories all the time of people saying they blew their 1000w MAX/500w RMS subwoofer with a 100w amp. That 100w amp probably only puts out like 50w rms. So to make the sub loud your instinct is to turn it up loud and turn the bass all they way up...I bet it'll sound horrible. Your feeding a lot of useless "distorting" power, way over the amplifiers RMS range. Thats exactly why you blew it up. I have two 15" L5s on a 2000w rms amp and they slam and sound beautiful. Nice deep bass with no distortion at all. So next time you buy an amp you might want to make sure it meets your subwoofers power handling.
