My left speaker amp is making these scratchy noise. I think that it is blown or sumthin what should I do. Can i bypass the amp thing or what. Should I just run speaker wire from my radio straight to the speakers in the back.

 

Is this a Bose system??? If it is, bypassing the amp thing will get you no sound.
Two choices for you
1) Repair the amp.
2) Install a 2 chanel amp, and run the two rear speekers off of it. I've done it and I think it works better that the bose amp. Get a good amp, not some cheap junk.
Both options will cost you about the same in the long run.

 

if it is bose, you are just better of replacing the speakers and deck all together. dont bother replacing with newer bose, and definitly dont go to the dealer to order the bose parts

 

I had the exact same problem. Last year I finally did something about it. I went to Tweeter and had them install all new speakers and a head unit and a CD changer. Best sound I've ever had in a car and much better than the original Bose.

 

I always thought the Bose system sounded good. When I installed the amp for the rear speakers I got one that you could boots the base and it really sounded good. Installed a CD changer in the trunk and all is fine.
