SOURCE: Bose amplifier does not work with a 6 speaker selector

your wall speakers may not be connected.... disconnect each speaker from the selector box and test with a small AAA battery to see if they are connected by putting the battery between each speaker's wires , you will hear it crackle ,then gradually connect each wall speaker onto the speaker connector box . If the first set does not work i suggest there may be a problem with your speaker selector box . Good luck

04 Infiniti sedan w/ factory Bose. Front speakers are not working (no sound at all) and I adjusted fade all the way both ways. Back speakers are fine. What's up?


If the rear speakers are fine, perhaps I can narrow this down. Fuses must be OK. Steering wheel audio controls connect to the audio unit which has a preamp function. The W/BK outputs connect to the left front inputs of the Bose speaker amplifier; the GRN/RED outputs connect to the right front inputs. Your ear test confirms the front door speakers are not working, therefore there is no front door output from the amplifier. The amplifier stages for the front doors may not be working or no front door amplifier input is being received from the audio unit. The fader and balance controls do not show on the diagram so must be on the front panel. They could be defective. There is a remote possibility of broken/disconnected wires

Power wire is usually yellow or red. A cheap test light from the parts store will tell you. The remote wire is almost alway solid blue. A volt meter will tell you for sure. Remember,the remote wire is very low voltage.

2003 infiniti g35 cd changer won't work-it gives an error message


Had to replace same unit twice in 2004 G35. Seems to be a bad model. Sometimes a dirty disk(s) will cause operation problems so make sure all disks are sqeaky clean, and if they are in unit for more than a month, remove, clean and reinstall. Use plain water and a soft cotton rag for dust, but windex for grease/oil/candy etc. Also vacuum unit face opening when cleaning interior.

No volume


The Bose system in the Z is wired to control the entire car's speakers. Each speaker has its own amplifier, and the OEM head unit puts out a line-level signal to each amp. Your Clarion unit puts out speaker-level signal (in effect, an amplified signal), into the Bose amps, and it's probably overdriving them and putting them into shutdown.

Your best bet is to replace the Bose speakers with aftermarket speakers meant for a speaker-level drive (which is what I did in my Z, and never once regretted it). If you do so, you'll need to run new wires to the speakers, or if you use the OEM wiring, you'll need to unplug the amps and run the wires from the amp harnesses directly to the new speakers. I think there is an adapter harness you can use that will tap into the line-out jacks on your Clarion, so that a line-level signal can be sent to the Bose speakers - I'd do a google search for "Metra harness 300zx" or something along those lines (Metra makes the lineout harness adapters - I use one in my Audi).

yes, you have a few options. Chances are, its your amp. 
1st I would test the speakers - find the amp under the back seat, then test which wires go to the front speakers and use a AA battery to check if the speaker pops with those two wires and the battery.  If it does pop, its your amp needing replaced.  You can switch out that infinity amp for an aftermarket one very easy. Just use a testlight, or voltmeter to test the wires, and switch them to a new 4-channel amp.  
if you need the wiring diagram, let me know...and dont forget to rate me! or ask for more help!
