These Retro Sound kick panels mount easily in your classic 1957 Chevrolet, and will fit most 6. 5-inch speakers. The speaker mount is angled to direct sound upwards towards the listener, and not at your feet. Kit includes driver's side and passenger side kick panels. This package includes two pieces of Retro Mat sound dampening for better sound and deeper bass. Kick panels can be painted to match the interior of your vehicle. These are for Chevrolet/Pontiac vehicles that came with no factory air conditioning.
