I got a 2003 touring model ( so yes that means bose). but my cars entire right side including the rear speakers play a high pitched flat line. I removed my door panel and swap the speakers with the driver side and it still does the same so i know the speakers aren't the problem I was thinking grounding?

I do have edfc so i'm assuming the previous owner grounded it wrong. Or it could be possible my amp might be jacked up as well..?

second post in need of some help! i used the search and i've been looking but no one has had the same problem as me

IF FOUND PLEASE POST LINK THANKS IN ADVANCED

sounds like your amp...

What do you mean "rear speakers play a high pitched flat line"

no music at all?

They play very low with slight static only at max volume and thats the entire passenger side any solution sGould I just buy a new boost amp or grounding kit..? Thanks finally a response :/

if it was a grounding problem for the input of the amp - then I would assume just fixing the connections would make a big difference.

if it was a grounding problem for the power of the amp - i would assume that both channels would be affected.

it sounds to me like the a channel of the amp is burned up.

Im busy with school but ima search for the diy amp removal as I have no idea where it is ill be checking for the wires to see if anything is burnt anyway to tell? I just hope some wiring is possibly loose thanks Jojo youve been of some serious help

Most likely, yes. However, it could be the source signal traveling from your head unit to the amp.

The amp is the most likely cause, but you could have an issue with the wiring between the two - or with the output from your bose head unit in the dash. The amp is fairly easy to get to in the back left of the hatch under the carpet, so if you can find someone local with a working bose amp to let you swap it out and test theirs, you'll at least know for sure before you buy something.

Otherwise, the amp is the best bet out of the 3 possible causes unless you were doing some work recently near the radio or underneath the center console (where the wires run).

hmm i have an edfc hooked up that runs underneath my steering wheel column and into where the other wires run. Im assuming it could be a possible grounding as well because of the edfc ( hope that made sense ). thanks spark im busy this week but i will be checkin in and updating around thursday because i got about 3 tests this week

more interesting things I realized that on my daily commute my sound turns up and down while driving like as if my wires are getting more power when the car is in motion ( alternator possibly charging ). I now am feeling confident that it could be a grounding problem any thoughts..?

doesn't the bose system have some automatic volume adjustment feature?
I took that HU out and replaced with a kenwood ddx719 so i can't look at my bose HU anymore

Oh if that is the case then I am stumped once again after class today im going to check my amp and see if any okufs are loose or burnt anything in particular I should look for?

okay i removed my trunk and got to take a look at my amp wires which appear to be perfectly fine unless my amp is burnt internally ( which i doubt because i still have sound on my entire driver side including the sub ) i feel like its my grounding problem? thanks any ways guys im going to take it to my friends shop to test volts on wires connected everywhere from my ecu to the amp and etc. im going to be checking if its a bad grounding wire or a bad grounding set up in general



if you guys have any ideas please let me know i'll update this thread until i fix it

Swapped my amp the other day with a Bose amp from a maxima (read somewhere it works..?) Still the same problem going to have my wirea checked for continuities

have you swapped channels on the input side of the amps?
or hook up some other source on the input side of the amps?

The amp should have the left side channels plugged into the left side; the right has right. Switch them to see if the noise switches to the other side of the car - and then plug a different audio source into the amp to see if it is the amp, or if noise is coming from the radio through the connections.
