So I've been trying to figure out what is wrong with my rear speakers in the 2091 XK8 convertible. The speakers are fine, I've replaced them. They sound like a mucky no music, occasional thump sound mess. No music comes from them. Then I read in 2001 the factory disabled the fade to rear option and they reccomend it should stay disabled. Mine was already enabled but to no avail.
Does anyone have the real scoop on all this mess with 2001 Xk8 convertible rear speakers? Something is wrong here.
thank you

Yes. Perhaps I do.

Sounds like you may not be happy with the system as designed in the 2000 - 2002 MY. The alpine system uses the rear speakers as subwoofers which are only going to put out sound in approximately 20-100 or 20-200 Hz (i.e. very low frequency). So, they will sound like low frequency thumping, grumbling, etc, designed to support the midrange/tweeters in the front. There will be precious little evidence of midrange in the sound.

Reminder of this very recent thread

with discussion in post #3, a TSB posted from Bob (motorcarman) that explains it in post #7, with audio samples in post #18, more discussion in #24, #25, #29, and #30. And reminder of the same discussions at the very recent end of this old thread

with repost and quote of the same TSB above in post #123, #124, #126, and another audio sample in #128.

Enjoy.

 

Well my 2001 has no "sound " from the rear. Just muddy noise that only detracts distortion and muddle to the front speakers. It can not be right. It sounds like a mess.

 

Quick question: with no fade (i.e the fade is 0 or off, not to the front, not to the rear, centered), can you actually hear the rear speakers over the front speakers? Or can you only hear the 'muddle' when you fade all the way to the rear?

 

when the fade is not enabled, it is at center. Its never off. So yes you can hear in my car what is a muddy sometines thunk sound. Tge farther toward rear you take it, it phased out the front so there is basically nothing but thunk on heavy base. It's a mess.

 

Why are there TWO threads on the same subject?

 

Appreciate it. Just a note, if you don't like the behavior you are hearing, you may need to consider an aftermarket system. I have a strong suspicion that any 2000-2002 MY replacements will behave similarly. Good luck with it.

 

TY, I refuse to believe this comes from the factory sounding like that. It does sound like a hybrid mess though.

 

I have a 2001 XKR convertible - what yours is doing doesn't sound right. Perhaps you need to replace the amp as it sounds like something has failed leading to the noise you are getting.

 

I tried to record video with audio and this forum wont accept it. Most of the time i dont know i have 2 rear speakers. But on occassion it will produce a very dull thud or thumping in a space of music with a lot of bass. The rears are in the box and are woofers not subs, but there is a SW sub woofer control that works. There is also a POS mode which works but I dont know exactly what it's doing. The rears contribute nothing to the overall sound and sometimes are annoying with those non musical noises. Lol.
Thank you

 

After all the help from many, it was definitely the Amplifier that had gone bad in the back. Now I have to decide if I want to upgrade the speakers. Thank everyone who helped along the way.

still not sure why I dont have tweeters in the back on the sides, with premium, but all good.

 

Did you replace with factory amp or aftermarket? If aftermarket, what di you do about the wiring? My 2000 does the same thing

 

I found a factory amp. It fixed the problem.
