I have a 2003 350z with bose package. I replaced the headunit with a Pioneer Avic-f700bt but kept the stock speakers about a year and a half ago. Within these last couple of months, the sound has been cutting in and out on the left side speakers. It happens when I hit bumps sometimes.

It's getting pretty annoying so please give me some input on what the problem could be and how I can go about fixing it. Thanks!

 

Are you serious??? You have over 1k post here. Double check your wiring or bring it to someone who knows something.

 

Lol the wiring is good. Its just that this problem was usually attributed to the stock headunit. Now that thats out of the equation Im still having this problem.

 

everything is stock except the radio ?

 

Yep.

 

if everything is stock

then i would think there is a loose connection

i would start with what was molested

pull the head unit and check every connection back there


you mentioned it was doing this before that HU was installed , and then the radio went in , the problem went away for some time , now it is back?

well since time is free i would check all connections starting with radio, then on the side that the speakers go on and off at then the rest

bose amp, HU, all speakers

 

^ what he said.

 

I dont know if youve notice but the cutting only happens when your ipod is connected. try playing a cd and youll notice that it does not do that. I have a 900bt installed and I had the same issue.
I think what happens is the head unit isnt calibrated according to the bose speakers... if you read about bose, their speakers are specifically calibrated according to the unit that comes with the car.
What it actually does is the head unit burns out either your right channel wiring(red wire) or the left channel(white).
take your head unit out and play it. you can test it out but unplugging the right channel first and then switching to figure out which channel is fried. I ended up replacing the cable to solve the issue, but it seems like its an inevitable problem. Im running a monster cable with an rca connection and a usb port. so far no issues.

I love pioneer and i think a more professional setup with amp and subs will eliminate the issue.
hope that helped

 

this is what you probably have right now:
