I have two Lanzar OptiDrive 1535s. I was running only one sub off of an entry level Lanzar amp and all of a sudden the sub started making a strange noise and not hitting as hard. It still hits, it just sounds like crap. I hooked up the other one, and about a week later same thing. These are competition subs, and I wasn't really pushing them, so I was kind of surprised. When I took the sub out of the box and moved the cone, I could see that while the fabric surrround that attaches to the cone wasn't ripped, it was separated from the cone where it was glued before. My question is this... Is this a symptom of something else such as a bad motor or blown voice coil, or can I just reattach it and use it?

Its actually a pretty good sized amp, Lanzar MXA282, its supposed to put out 1000x2rms at 4 ohms which is how i have it wired. the speakers take 1600rms a piece. I bought a new car, and was going to get a decent amp to power them, I was thinking the Optidrive4000D, but I have a 2000 chrysler 300m, with computer controlled alternator, and I doubt if I can draw the insane 550 amps that the optidrive will take on a stock alternator

each sub is in its own chamber in a sealed box.

You are either getting clipping or you are square waving your amp due to a power rating mismatch to the sub. Sounds like the amp is way too small for the speaker in the way you have it connected.
Yes, you can re-glue them and there is a GC brand speaker glue for that use, but it is not likely that there was anything wrong with the manufacturing of the subs.

you can reattach the fabric. are both subs in the same box, if so, do they share the air space or are they separated from each other? Also, under powering sub is the number one reason they blow...when the amp is too small, it distorts and send distortion to the subs. speaker cannot reproduce that kind of distortion for too long...it overheats and shorts the voice coil. reattach the fabric and take a listen to see if they are blown...you'll know right away.

This is a common problem with speakers, especially in cars where temperatures get so high. It is difficult to bond the surround to the cone. It is for this reason that Kicker first starting stitching the surround to their cones long ago.

By far the biggest enemy of a subwoofer is being underpowered. It's actually much easier to damage a subwoofer by under powering it rather than over powering. This is due to clipping which can toast a subwoofer very quickly. The woofers do work well as paper weights! In the future just make sure your amplifier and subwoofer power rating match up.

reatach it if its not under waranty thats just poor manufacturing and it became unglued simple as that just dont put too much gluee cus then the sub wont move!!!! good luck

often while they start to return aside, you have pushed them to the snapping factor. exchange is now what you're able to desire to do. Your amp amy additionally be the subject. incorrect impedance matched w/ no longer sufficient means to effectively force them.
