This customer contacted us to have the rear speakers replaced in his 2004 Toyota Corolla.
His factory speakers had aged to the point of making strange sounds and where well past the point of needing an upgrade! In the Corolla the to replace the rear speakers you must first remove the panels to the left and right of the rear glass. Then we can finally pull the rear shelf so that we can access the speaker mounting screws.
We installed some Kenwood KFC-6965S in the factory location after soldering the OEM wiring directly to the new speaker.
