Hey there. I bought my car from the previous owner and noticed that the rear audio was not working. Randomly I gave my sister a ride one day and it started working, and then it stopped after I turned the car off and started it again later. I figured that there was maybe a bend or a bad connection in the wiring. I opened the trunk and I couldn't see anything wrong with the wiring. Today I gave a couple friends a ride and I noticed that the back speakers started working again. I was thinking that maybe its because someone was sitting in the back seat or because there was more weight on that side that it made the wire connection complete. Today I had some free time so I took the back seat out and the speaker panel. I turned the car on and the back speakers were working. I'm not sure if the panel was seated so as to cut the connection in the wiring because I did not see anything that looked bad or damaged. I was hoping that someone on here may have had a similar problem and might just know exactly what it is. I don't believe its a problem with the speakers themselves because they sound fine, although I have not gone so far as to test different speakers on the wiring. I also took the dash off and checked the stock CD player wiring to see if maybe there was a loose wire.
Again, any help would be greatly appreciated!
