Comments about x6 4x6 PIONEER TSA4672 4x6 SPEAKER:
Bought these to replace stock rear speakers in my '06 Silverado. Once I had the wall panels off it took 10 to 15 minutes per speaker to install. This included attaching speaker to mounting bracket, splicing wires, marking and drilling holes and mounting speaker. Note, you will need to pick up four sheet metal screws per speaker.
The sound is great for a small speaker. Way better than stock speakers.
