stereo troubles
 

ok guys i'm hoping someone here can lead me in the right direction this might be long so thanks for your patience. :thumbup:

this refers to MY '02 4.4 with DSP and NAV system.

when i picked it up about 4months ago a few of the speakers were not working properly and the sound kept on cutting in and out gave a feeling of a deaf sound almost it didnt feel full :wtf: . so i took it to the $tealer they looked at it changed out speakers which were blown from a few days prior when they began crackling. picked the car up speakers seemed to work :) yet the cutting in and out still persisted :( . took it back to the shop had them look at it this time they swapped out the radio unit since they found a tsb which stated that if radio cuts in and out change the unit. so got the car and again for few days it worked fine at this point im confused :confused: . later on i found a leak in the trunk which coincided with my speakers crackling again. so took it back to the shop they took care of the leak and changed the amp which they claim and at this point i figured was the only thing left to swap out but due to the water it was actually damaged so new amp. still now i have no leak new amp new radio supposedly new speakers and the stereo still cuts in and out its more noticeable with the DSP on so im thinking maybe its DSP? is there anyone here who has any idea because i have no clue :dunno: and at this point im um a bit :mad: to say the least

The DSP is actually all in the amp.

Is it possible that the damaged amp (it sounded like a damaged amp to me as I read your post) damaged the new speakers before it was replaced? Or the tuner?

thats what im thinking because the very last time it rained all of my speakers started to crackle and pop as when you plug speakers into the wrong port on the computer and it was happening even with the stereo off so yes definitely what im thinking as well but why would it work fine at first and then stop thats the problem. but i will definitely take the car back in and request they change everything possible with regards to the stereo system i just wanted to know if anyone had any suggestions ideas cuz its quite irritating as you can imagine.

I think this is the perfect opportunity to upgrade the whole amp-and-speaker setup so the stereo is as good as the car... it's only $4k or so.

that sounds awesome however not really in the mood at this time for the upgrade i'll stick it out with what i got for now. thanks for the info though ill keep it in mind

Do you happen to know the TSB for the headunit? I just got a 2003 4.4i with Nav (non-dsp) and I've noticed it doing similar things. Driving along and the audio just cuts out all together. Originally, I thought maybe I was getting bad reception, but its doing it on every local station that my other vehicles have always had no problems with. Any additional help/ideas would be great!

probably a bad battery.

Even if your car will start a low battery will cause items operating on the I/K bus
to shut down. The I bus will shut things down if too many errors. Your issue sound like a battery issue.

Battery is under the spare tire. Look at the magic eye. green = good black = bad

Happened on my daughter's 323. The sound kept cutting out. It turned out that the amp connector contacts were corroded. I unplugged the connector, sprayed some contact cleaner, plugged it back and have not had any problem since.

Thanks for the info Martin. I chceked the battery and everything looks good there. If it were the battery would you expect the whole nav screen to go blank or just cut the audio? The issue seems to be getting progressivly worse, I just haven't had time to go to the dealer.

Does a non-DSP system have an AMP? I'm correct in my understanding that if I go to Menu on my nav screen and don't have DSP as an Option that I do not have DSP at all, correct? If there is a factor amp in a non-dsp config, where is it located?
