Everything was working like a champ, now I get nothing. A few nights ago the wife and I were driving home, sound worked great. Next morning I get in the truck, no sound. I pulled the deck and played around with some wires, got the sound going again for a few minutes then stopped working again. Now when i turn the deck on I hear a faint pop noise just once from my front speaker, and then nothing. I have a 1999 Tahoe, I do have a factory installed amp, and I did run the remote to the amp. As I said before the speakers were all working and sounding perfect, and then this happens. Do I have a problem with the dash harness? I can't imagine it's a fuse because it worked for a while then stopped, but started working again for a while longer before it stopped again. I have the remote wire to the factory amp (dont know where the amp is, just going off the factory dash wiring harness)
Any help would be *GREATLY* appreciated. Thank you so much!
It's either a wiring problem or an internal intermittent short in the deck itself.
How old is the stereo?
Triple-check your wiring first!!!
Try connecting one speaker per channel individually and see if that helps you isolate it.

Here is the wiring info for your Tahoe.
Now it is sounding more like a fuse or problem with the factory amp (which is supposed to be under the driver's seat), but as you said, the amp is only supposed to drive the rear speakers, so that might not be the entire issue.
Anyone else have any ideas?
Every car place I call says they want me to bring it in so they can charge me way too much money. If all 6 speakers stop working, is there any way it could be the factory amp? I've searched for the amp, some say it's under the seat, some say it's under the dash, and others still say that it is in the back under the wheel well plastic thing.
All I know is the power to the deck (factory and aftermarket) both work just fine, when the car first turns on and you power on the radio, you hear a very faint pop noise coming from what sounds like only the front speaker ... but I'm still clueless.
Thank you so much for the help this far ... i really appreciate it.

No car place is going to tell you how to fix it over the phone for free. It doesn't do anything for them, and it's a liability issue if you do what they say and fry your deck (or worse one of the factory harnesses).

Maybe - but the info I saw said only the rear speakers were amped - as did your data.
Two things to try:
Alright I think I may have put together an idea that makes sense.
When I installed the JVC deck, I first did not connect the remote because I didn't know my Tahoe had a factory amp in it. When I played music, only sound came from the front two door speakers, and very faint sound came from the very back 4x10's in the cab of the truck. The two rear door speakers did not make any sound. In researching what I have, I think what I've found is that there was enough current from the deck to go through the amp and still make the speakers work...
All 6 speakers in the truck ARE powered by the factory amp, so I think what the problem is, is the factory amp is blown. It was going in and out a little bit before, speakers not working sometimes then working again, so I'm pretty positive this is the problem. Now I need to figure out where the factory amp is, because everyone says something different and I've not found it under the dash or under any of the seats.
Anyone know what fuse goes to factory amp in a 1999 Tahoe, and where the amp itself is?
PS, thank you so much for the help, it's truly appreciated.
Sounds like you are on the right track.
CF says the radio uses fuses 17 and 19. I assume one of those is the amp. (Of course, they also said the amp is under the driver seat).
You can't just pull the fuse and have the signal go through the amp - you will need to bypass it.
Without stating the obvious - if you either follow the HU wires backward or the speaker wires forward, you will eventually get to the amp.
An easier solution might be to just run new wires from the HU to the non-working speakers and cap the existing wires and splice in where you know you are beyond the amp.
Tried both of those fuses yesterday, got nothing. All 6 speakers aren't working, from what I heard speaking with a professional install guy all 6 speakers DO run off the amp. the reason I was getting sound out of the front two speakers before I ran the remote line is because there was enough current going thru the amp from the HU to run the front two speakers. the very back two (not in the back doors, in the back of the cab) speakers had faint sound as well, and now nothing.
I'm like 99% sure it's the factory amp, and I dont mind replacing it, I just need to find the **** thing now, heh.

The JVC HU likely puts out more power than the factory amp - they just left the amp in there for convenience (if you meant replacing it with a factory amp). If you meant replacing it with an aftermarket amp - that would sound even better but you'd need to upgrade your speakers as well.
I'm not entirely sure that I'm explaining myself well enough =PI put the HU in myself, so there wasn't anyone that left the amp in or whatever, cause I installed it and I've not been able to find the amp. Looked in every place suggested, haven't seen anything.
I'm definitely game for getting a new aftermarket amp and speakers, but I dont like the idea of paying someone else to install. If I can just locate the aftermarket amp I am good to go, the rest of the install is easy.
SOMEONE TELL ME WHERE THE AMP IS!!! lol.
TigerHeli bro I truly appreciate your help man. It's awesome that you're willing to take the time to talk this out with me, you're definitely helping me to figure this stuff out =P

I confused you ...
Left the amp in there for convenience -
When you have a factory amp in the system and you replace the HU, there are two ways to handle the amp:
Do you have a DMM?
If so - for example - pull the HU out of the dash (unplug it) and pull the LR speaker. Connect the + and - speaker leads together with a jumper wire at the speaker, and then test for resistance at the LR+ and LR- leads at the HU. If you get zero resistance, there is no amp in the system, and now you have to figure out what the problem is, b/c it's not the amp. If you get fairly high resistance, there is an amp, and you are back to either bypassing it or running new speaker wire to cut it out of the loop.
Because my name is on the business, I work hard to make sure you get the best possible shopping experience. I look forward to hearing your comments .
