I have a 2004 Tundra. I just had a new Pioneer deck installed with a scosche harness.
The system worked for a couple hours, then my output seemed to just quit. When turning up the volume I could make out a highly distorted version of the song playing, but it more closely resembled a robot distress call than music.
I took it to another shop. They installed a harness from another manufacturer but I don't recall the name if they even mentioned it. Again it seemed to work fine until I noticed my front speakers were cutting out intermittently. Finally, the front speakers just quit. Arg.
I know almost nothing about this stuff, but I need to find a solution. If anyone has advice it would be greatly appreciated. $600 deep into this with nothing but lost time and mounting frustration. Oh, and this all happened on a 10 day roadtrip which I am still on. The 'silence' is enough to turn what was to be a relaxing vacation into... well, something else.
I'm new to the forum and this is my first post. I have found similar posts here but nothing quite like this. Please excuse me if this is a redundant thread.
There are a ton of knowledgeable folk around here who are more than willing to give you suggestions as to the cause of your issue. Non of us will be able to come up with anything better than a WAG without more info however.
1. - Model of Deck?, how is it connected to the rest of your equipment?
2. - Equipment list (deck only?,,, amps?,, new speakers?, how many, where are they located etc)
3. - Professional install? (sounds like it but can't assume)
4. - About the same run time from fix to fail each time?
5. - Did the speakers cut out when you hit a bump,, when you turned the truck on,,, during normal driving? etc.
6. – Are the rear speakers still working now,,, do you even have rear speakers? (sounds like it,, but maybe not)
7. – Does the symptom come and go,, or once it’s dead,, it’s dead?
You get the picture,,, the more details you can provide re. the equipment, failure, and symptoms,,, the closer we may get you to a resolution.
My guess right off the bat is that it sounds like you may have a connection problem inside of the deck. It's more than likely a connection issue of some kind.,,, it may be something as simple as the harness plug isn't seated or making good contact with the receiving plug at the back of the deck,,, or it could be as complicated as a cold solder joint on one of the Pioneer circuit boards.
From the sounds of your first symptom,,, it sounds like it's internal (inside the deck),,, from the sound of your second symptom,,, it sounds like it may be an external harness issue. Since it worked at first (both times),, but failed twice after a certain amount of run time (both times),,, it could even be heat related at the circuit/component level. I'm assuming that you had it worked on by competent folks. Since it's been worked on twice,, and the aftermarket harness has been replaced,,, I'd hope that two different "professionals" wouldn't miss a simple connection at the back of the deck,,,, but I work with some so called "professionals" that are complete a total 'tards,,, so that's never a good assumption to make.
Again,,, I'm basing my WAG's on a VERY incomplete list of possible variables,,, I couldn't approach a SWAG without more data. You just can't get too detailed when it comes to all the variables while trying to diagnose a problem like this via text info.
Give us more details, and it's likely someone around here will nail it for ya. Good luck.
The truck has the OEM JBL premium sound. All that was changed was the deck with the addition of the harness. The stock one was fine for my needs but had mechanical failure of both tape and cd at different times, making radio my only source - which can only serve you for so long in great northwest.
It was a "professional" install done at CarToys.
The deck is a Pioneer Premier DEH-P310UB (and I do NOT like it but that's beside the point). It was first connected with the Scosche TA2073B harness. The failure actually started soon after the first time I plugged in an iPhone/iPod but could be unrelated. I let it go and kept driving, periodically messing with buttons and settings, then it mysteriously came back on after a while, but crapped out again for good. I do not know the model of the second harness, but they said they tested it back and forth and the new one worked, the old one didn't.
The second harness worked fine, then the fronts began cutting out a little. It seemed more frequency-based than anything. At a swell in a song, the fronts would come back in, then drop out when the amount of power/sound would drop. Eventually they cut out completely but the circumstances didn't seem related. I did notice that the R and L AND front and back channels are reversed on the new install. Could that cause a difference in power distribution that would screw up the front channel? This might be a good time to reiterate that I know basically nothing about this topic so you're probably chuckling at my terminology.
Yes the rear speakers are still working.
Getting ready for 10 hours of driving today with nothing but road noise and my crappy voice trying to sing. awesome.
Swapped the RCAs and now it's the rear speakers cutting out.
At the shop, they recommended bypassing the stock amp altogether and skipping the harness. They said the Pioneer deck is powerful enough for decent sound and that if I didn't like it I could upgrade to another amp. More money.
I think it's lame of Toyota to make it so difficult to use standard car audio components. Fail.
Might be the harness, Ive read here there are problms with the scosche and jbl system, something about the factory unit is digital and the harness is analog or something to that effect... seems like people bybass the amp and it works like a charm.
I have the Pioneer f700-bt the only harness I used was for power, I hard wired 2 kenwood amps and 8 kenwood speakers plus the sub..
sorry Im not much help... but here are some other posts read them to the end, they may help.
I'm using a different harness now and I'm only getting sound in the front speakers. Also, the sound I'm getting in the front is poor quality, and the volume is intermittent. In other words, the sound momentarily dips down about 50% of the current volume randomly - about once or twice every minute.
I dont think it's just the scosche harness, if correct, the head unit and amp are digital and the harnesses are analog...
Now on computer systems I have set my sound card (default) to analog and had a digital system and things were crazy... all sorts of crazy sounds (almost like scrachy underwater or far away sound) and the more you turn it up the worst it would get.
if it's the same as computers (I dont see why it would not be) it would make a difference, you may have to run an aftermarket amp.

just bypass the original amp behind the change holder. but then you would need another source of memory. i tapped into my 12v power outlet on the bottom and works perfect.
I dont have the JBL system, but I had no sound when I hooked up my Pioneer bead unit(about two weeks after I got the truck). Then I did some research and found out about bypassing the factory amp under the rear seat(thats where it is on my truck). It was a pain in the arse but it worked perfect. I think that has to be your problem. The factory HU just sends a low power signal to the amp, so when you hooked up the Pioneer, it was sending large amounts of power to the input of the amp. This is not a good thing for the amp.
