No sound from front speakers? 2003 gtp Bose system

Ok, I'm usually not this challenged when finding an issue but I can't figure this one out. About a month or so ago it seemed the radio didn't sound the same and when I do balance all to front the speakers are not making any sound, not any real sound that is. I've checked fuses in glovebox and both are good. Is this an amp issue in the trunk for the factory Bose system or a head unit issue? All stock equipment. Is there a fuse I'm missing somewhere? Anybody else have a similar issue before?
Thanks

They are probably just blown if its all stock. When I bought my car, the foam surrounds where gone and they rattled a lot.
 
They were just fine then they just quit working. I've had the car for 11 yrs and it was fine before? Who knows? If it ever warms up I'll get into the trunk and look at the amp. Idk what else it could be? That or the head unit. If the mids are blown, the tweeters would have sound when turned all to front. Right now I pretty much have nothing up front

I turn the knob from middle to front and there's still faint sound from the back but nothing from front. Perhaps a "white noise" sound from fronts. No audio or music to speak of. This is a first for me. It's like they are powered yet getting no audio signal from head unit to play the music.

Its happened to my dad in his old GP, the rears literally just stopped working. We replaced them and it was fine. You could always test them with a DMM to see what Ohms they are reading. That would tell you if they are blown or not. I don't know much about the bose system and the amp. If you had any kind of spare speaker you could remove one of the non working front ones, ghetto rig a spare one and see if sound comes out. Would tell your if its the speaker or amp/wiring ect.
 


I do have some speakers I just took out of my f150 last week. Stock ford ones but they work.

I would suggest that as well. I would lean towards a channel being burnt if your getting interference and power to them.
 
I will add, if it does end up being bad speakers. To replace all of them in the car, because soon they will start to foam rot, rattle/die. Probably help with SQ also.
 
I've had blown speakers in the past, they usually just sound like #%%t and rattle but have sound. Lol I'll mess with it when I get some time and see what I come up with. I was hoping it was just a fuse for the front ch of the amp I was missing? Oh well, nothing is ever easy right?

I don't know about the fuses on the bose system but you can check the connections to it. you may have hit it with something. its not exactly tucked out of the way
 


True! I'll look tomo after work. I'm stuck here 12 today and it's suppose to be warmer tomo. I'd have to shuffle cars to get it into the garage.

Ok, update. I messed with the settings a bit on the way home and it seems I've got some audio pass through the amp, just not amplified at all. You can hear it barely, but you have to turn it all the way up and the sound is very faint through the tweeters at top of door. I'd say it's an amp issue myself but I'll look in the trunk tomo.
Thanks for the tips guys

Looked at this a few min ago. There are no fuses in the back at the amp. All wiring is in perfect shape, including rear speakers from what I saw from the bottom side. Meaning, no rot on outer ring of 6x9 or the smaller one. Is this perhaps related to the infamous ignition wiring harness? I replaced that a few yrs ago and it fixed my headlights flashing, heater blower motor, power moonroof, among other things. Is this amp somehow connected to this stupid harness too?

I wouldn't think it was a fuse if you are getting good power to the rears and not the fronts. its possible that either the radio's out puts are bad or the amp isn't amplifying the fronts and more.
any other inputs or results since Friday?
 


Nothing more to report. It's something more going on with either the amp, head unit, or that damn ignition harness. The newest development is the display-clock on radio is off or blank sometimes. I can tap on it and it comes back on.

that happens to them its a bad connection at the light behind the clock. If I were you and had the money I would get a new amp and run the front and rears and see how that goes. a simple 60amp by 4 channel should do well
 
No I haven't! I'm surprised somebody hasn't got something posted somewhere?!? I know mine aren't blown, they have no real sound. It's annoying
