So i'm driving tonight.. and I lost my high end when I turned the volume up a little bit. It sounds like my tweeters just stopped working. If it was one, then I would say it would have probably been the speaker, but I lost the higher end out of both speakers, I checked out the amp as well, and everything seemed ok, I even swapped out the back to the fronts on the amp to eliminate an amp problem as well. Anyone have any ideas what happened?

Do your tweeters run through a passive crossover network, and if so are the tweeters protected by a fuse sytem or a light bulb and if so is the light bulb burnt out. That would be my best guess.

I doubt it, but still possible. You probably blew your tweeters up.
How exactly did you swap front to rear, rcas or speaker wires? ------------- Certified Security Specialist

I would say that blowing both tweeters at the same time with no warning whatsover is probally more unlikley than the bulbs going but both are still improbable.

I was thinking more along the lines of the bulbs in the crossover being wired in series with the speaker. Usually they are parrallel so that they absorb dc current. If they are series then it absolutley could be the problem, but if not then there is definately something wrong.

Actually.. I don't have a crossover with my front speakers. I am sorry, I should have been a little more specific. I have MB Quarts in my front doors, but the tweeter is built in. It's a coax, not a component set. I don't even know if its the tweeters for sure, but I was playing a bass song (I keep my bass practically off on my Quarts, that's what my subs are for), I jacked up the volume.. and all my higher end sound went bye bye. The sound is more of a flat muddy sound now with a lot of midrange, but no higher end anymore, and that's the case with both of the speakers, not just one. I am baffled.

sounds like you got a frequency spike or a bit of DC leakage and zapped/shagged/smoked both tweeters...... was the system clipping? come on.... be honest........ ------------- Kevin Gerry

nah seriously, wasn't clipping or anything like that. As a matter of fact, I keep the gain really down on the amp driving them. Last year, my back speakers went out totally too, just stopped working, and both at the same time. Had my car re-wired just in case being I wanted a thicker gauge anyways, and everything was ok before, and after the re-wiring, and they said nothing was wrong to begin with, just sounded like speakers that blew out. The amp driving them is a year old JL amp. Being it can't be the amp, I think it must be the speakers themselves, so I went to Crutchfield and ordered a Infinity Reference Component set for the front, and Infinity Kappa's for the back. I liked my MB Quarts, but I heard Infinity's back last year, and to be honest.. I didn't hear much of a difference, and if anything, I liked the highs better on the Infinitys. Plus, alooooooooooot cheaper.
