Replaced front speakers

[denalianyone]

Replaced the front factory BOSE speakers on my Lade and the new ones don't work either. I tested the resistance on the new speakers and they both work. Not sure on
my next step

Amp??

 

[denalianyone]

The fuse for the factory amp under the hood is good. Plus the rear speakers and center dash speaker works as well.

I wonder if you could isolate the front speaker wires before the amp and attach a test speaker.

I'll look into that

IIRC, the signal going to the amp is very low on certain BOSE systems. I think it was that with the regular BOSE, the volume of the signal going to the amp was controlled by the head unit, which changed the power on the signal wires much like an aftermarket amp would be when connected to the line-level input. On the LUX BOSE, the signals are low-level and are at a steady power level and the volume is controlled by a data BUS to the amp. He may be able to test the amp's inputs with a DVOM set on a range of VDC that coincides with his type of BOSE system.

Again, this is what I recall at the moment and it may not be (entirely) accurate.

The amp only effects the front speakers?

It controls all speakers, but the front channels may be bad.
This may be a really stupid question, but did you check the fade setting on the head unit?

 

[denalianyone]

Yes I did

I hope you didn't take offense, but sometimes in our frustration, we over look the simplest stuff.

Do a pop test on the speakers to ensure they work. Check your old ones why you're at it too...they may still be good too (get some $$ back). After you know the speakers are good, test the wires with a volt meter to see where the current stops. Where the current stops...there's the problem.

Sounds like you have to work backwards. Since speakers test good, I would use a multimeter to see if the harness from car side is getting power. If not, cant he test the positive wire on amp going to those speakers to see if power is crossing? I highly doubt there is a fuse just for front speakers or anything else that would single them out. Do the tweeters work as well as back speakers? Just door speakers giving you issue?

Yup just front door speakers

Now I bought a brand new OEM Bose amp and now only the driver side tweeter and front driver door speaker works. The odd thing is I still don't hear the door chimes, seat belt chime or key left in the ignition, or blinker clicker. I thought those chimes come from the driver side speaker.

Did you test anything or are you just throwing parts at it? You gotta work backwards, TESTING parts and not work backwards replacing parts. You rule out the easy stuff first which would be the speakers. Then you check the signal coming out of and in to the amp. If there's a signal going in on all channels but no signal going out on all channels, then the amp is at fault. If there there is no signal on the front channel(s) going into the amp, then the problem is further up the line- such as the head unit or the wiring between it and the amp.

The factory Navi tested out fine and was reprogrammed. The speakers tested with a multimeter and are working. Not sure how to test the signals going in and out of the amp.
There are four connectors going into the amp and not sure where to start.

It turned out to be the outputs on the back of the factory navi. Smh!! Time for a double din or custom iPad install. [emoji848]

Glad you got it worked out. If you had access to a Tech2 it would likely have solved this problem for you in minutes.

indeed... i installed new front speakers and didnt tuck my wires properly...when i rolled down the windows it snatched the connection apart...lol
