I have a 2005 Chevy Trailblazer and over the past couple of weeks while driving, the Passenger dash tweeter and Passenger back speaker will be playing normal. When I hit a bump, it starts making a screeching feedback noise. I'm assuming the tweeter and speaker are blown? If so, I would like to just replace them with a plug and play speakers - maybe Factory OEM to make my life easy. I'm having hard time finding the speakers and part numbers online. I watch a couple of YouTube video's and they are showing replacements using new non-OEM speak and cutting new holes bigger in the dash and door panel. Suggestions on where to purchase cheap and part numbers?

Thank you

KC

 

Doubtful you have a speaker problem. I`d bet on the radio itself. crutchfield.com
