i have been battling this god awful issue for over a year now. i have 2 JL speakers in the front doors and 2 kenwood speakers in the back.

originally i bought the headunit and the 2 front speakers (kenwood) at the time because i did not have enough to buy the back 2 speakers. issues started happening pretty much on my way home from the stereo shop. i went back and forth with the shop and they cant find anything wrong. i found if i faded the sound heavily +/- 9 to 12 to the front or the back the issue didnt seem to happen and i could crank the volume up to compensate for not having all 4 speakers bumping. i figured the back 2 OEM speakers could be the problem.

so i bought 2 jl speakers and put them in the front and put the kenwoods in the back. still had the same issues, tried fading to the front and the back and could crank it up pretty loud with no issues.

at this point the shop decided the head unit might be bad so i took it out and shipped it to kenwood with a long explaination of the problems going on with it and they sent it back saying there were no issues found with it. so the shop put in a temporary replacement for the time being to see if that would help and it didnt, the problem persisted.

AT THIS POINT where i am at now, the shop decided to put the OEM speakers back in and see if the speakers i put in were the problem. after going back to oem speakers i am STILL having the same problem after hitting about 20-22 volume level. it sounds like **** and even sounds worse when the volume drop and fuzziness kicks in.

ive taken this thing to multiple shops and they all say everything is good, the wiring the speakers the head unit the connections are all good. why wont this thing perform as normal????

 

Perhaps your head unit can't push the aftermarket speakers? May need an amp.

**EDIT: Didn't see that you swapped the stock speakers back in and the problem was still there. Fail on my part.

 

Did they ever try bench testing it out of the truck? I'm thinking something with the wiring or the supply power.

 

no they havent, its happened with 2 seperate head units though. that should point to internal wiring/power right?

 

Most likely a problem with the wiring somewhere in the system. Possibly getting a little ground out somewhere. Or possible not a good ground to begin with.

 

i posted this on another forum but ill just copy it here.. http://www.caraudio.com/forums/head-...ml#post7735331

well my issue im having is with a kenwood excelon 494 unit so dont go dropping money on it either.

im having more or less the EXACT same issue as you.

following my first post, just to reiterate i have tried the following combinations

new head unit + new speakers

random head unit + new speakers

new head unit + original speakers

the only thing i have not tried is original head unit and original speakers. the only thing i can think of at this point besides that is that there is a power issue with the alternator (more on this later) or may need all new wiring from the battery all the way back to the head unit and speakers, or possibly a capacitor (have NO idea why i should even need one just to power 4 gd speakers)


the reason why i say the alternator might be an issue is because i had a weird check engine light come on the other day and i had it read at the car repair shop. i forgot what the code was but it had something to do with rear abs speed sensor. i looked it up and came across some chrysler forums where a bunch of jeep/dodge guys were getting some weird codes thrown from time to time and they said that they get weird codes sometimes when they have unsteady voltages running through the truck. i had the car repair shop clear the code out and the check engine light hasnt came back and its been a few weeks. also even a few months prior to this last code that was thrown i had another check engine light but it happened in the middl eof the night and it disappeared by morning time and i never got a chance to get it read.


anyways i am so **** sick of this prob i want to poke my eyes out.

 

bah..noone has any suggestions?

 

What is the actual problem...sound bad distorted...no sound...ya kinda skip over the symptoms....also who installed the stuff? Bestbuy? Your local teenager? Or a private stereo shop....did you try putting everything back to stock

 

The stereo works at normal function for about 5-10 minutes of play. After that the volume decreases and becomes distorted with only the rear speakers producing and sound. Shortly after all sound is lost. The deck still had power, and goes through all functions, the clock functions and all Bluetooth devices can connect, just no volume is achieved. After the truck is shut off then restarted, volume is back, but again for a short time until all volume is gone thereafter about +\- 5 minutes of play. Our local mopar/ASE mechanic who has done all of our 5.9s and 6.7 work did the install.
