alright... I've searched forums and nobody else has this exact issue. the right mirror mounted speaker on my 2001 mach 460 system keeps getting extremely distorted to the point that you can't tell what the music is coming out from it. This is the only speaker that does that, and this is the Third time i'm going to have to replace this speaker... and this is the only speaker that does that. please help me, my car doesnt get used that much, i have sub 50,000 miles on it and this seems just plain excessive.

 

is the whole system stock?

 

yes, it is completely stock mach 460. The previous driver had installed an XM radio, but that was removed once i purchased the car (last year). He had told me had to have that speaker replaced twice before, and that the audio professionals who installed it said it should be fixed permanently. I have not begun any mechanical modifications on the car yet either, since i wanted 2 spend the money to fix this first.

 

I would be curios as to whether you were playing the same song every time it blew.

 

I can't give you a reason why one speaker would continue to do this as it makes little sence. If the speaker keeps going bad then we need to take a step back an look at the next componant on the line(the amp) to see why it keeps making the speaker go bad?

 

yeah... it blew on only half volume or so... although i will admit i had it cranked up to near full earlier that day. So potentially you think this might be an amp issue?

I was also thinking it might be some faulty wiring... or some abrasion to the wiring. I know that speakers placed near windows or outside components are prone to wear out quicker than ones that have more insulation... but this just seems a little rediculous

 

If your cranking it to almost full blast I would bet your problem is two fold.

First, that stock amp is clipping like crazy.

Second, your tweeter doesn't like that clipped signal so it blows.

There are two solutions.

First, turn the volume down and limit your musical enjoyment.

Second, buy yourself a system with some *****.

 

Wow, that's rediculous to listen to a system that loud.. Especially a stock one that you are going to get a bit of distortion from.. I gotta go with preal on this one..

 

well it's a convertable so i loose alot of the sound to the outside world... and idk, just felt like testing it. oh well, here goes more money. the previous problems of that tweeter occured when the volume never came near that high though.

 

This might sound wierd, but the volume is only part of the equation.

Your driver gets its signal via electrical pulses that should look like sine waves. If you were playing asource (CD or Radio)with a very low signal you probibly had to crank up the volume to hear the music even at a reasonably volume. When you cranked up the volume you were driving the amp harder so it started to clip. A clipped signal is a square wave, not the smooth oscilation of a sine wave. That clipping oscilates out of control and eventually the signal the speaker recieves has too high a square peak . then theVC puts off a little magic smoke or somethingelse bad happens and your speaker is blown.

You really shouldstart another system building thread with a budget so we can hook you up.

BTW, my wifes last car was a convertable, sebring,and she blew 4 of the 6 stock infinity gold speakers.
I put a really cheap, but high quality audio system in in, and never had another problem.
