my 04 bose coupes has been giving me trouble lately. When i shift hard or brake a bit too hard, the drivers side front and rear speakers either gets really low or just stop working until another bump in the road or an akward turn. what should i do? i was thinking of replacing them with different stock speakers but they work perfectly fine until i hit a bump. I really dont wanna go after market at all. Any help would be great.

 

have u check to see if the speaker has come loose from it's mounting position? Also, check to see if the speaker wire is being grounded out or pinched in some type of way. If all those things are fine then move to the HU.. Check to see if any wires are loose or touching metal of some sort.

 

I took the panel off, checked the wires, unplugged and cleaned the wires. Drove around the block n it still does it. tomorrow il check the head unit. what should i be looking for?

 

Sounds like the ribbon cable connecting the radio parts is loose. Check this post here:

12/18/2012 update: clipped the ribbon as per the diy and cleaned it. Running much better!!! two days of smooth music. until today i hit a bump and it went back to one side but 4 mins later went right back to the correct way of playing from all speakers. gonna update again this weekend
