These RetroSound direct-replacement kick panels mount easily in your classic 1968-72 Buick Skylark, Chevy Chvelle/El Camino, Oldsmobile Cutlass, and Pontiac GTO/Lemans, and will fit most 6.5-inch speakers. They are injection molded for a perfect fit in vehicles with factory air conditioning. Includes driver's side and passenger side kick panels. You can use vinyl paint or plastic adhesive paint to match the panels to the color of your vehicle's interior. These 6.5-inch high-power R-652N speakers are a great way to upgrade the sound in your vintage. They use a neodymium magnet structure for high power handling in a slim-mount design - mounting depth is just 1.8-inches (51mm). Santoprene surrounds deliver the most natural sound possible with no distortion. Mylar tweeters produce crisp, clear highs. Speaker grills are included.
