In this video I replace the stock rear door speakers in my 2005 GMC Envoy with a brand new set by Infinity called REF-6522EX. These speaker are excellent quality and won't break the bank! The stock speakers in the rear doors were very muffled sounding and quite frankly terrible. The install was very easy and would take the average do-it-yourself person about 30-45mins to accomplish.

The GMC Envoy and Chevrolet Trailblazer are pretty much the same vehicle so the process will be virtually identical.
