Old Ford Mustangs are cool vehicles but they weren't designed for great sound. It's particularly hard to find a good spot for aftermarket speakers, but now RetroSound offers a neat solution install their MKP646-S enclosures in your Mustang's kick panels and start rocking out.
The package includes two ABS plastic enclosures and a set of RetroSound's R-652N 6-3/4" speakers. Each enclosure holds a RetroSound speaker, angled up toward your ears to create a more powerful stereo image. These speakers will work well with a factory or aftermarket radio, but they handle up to 50 watts RMS so they'll be very happy with an outboard amplifier.
Compact, paintable enclosures
The R652N speakers have a mounting depth of less than 1-3/4", so these enclosures don't take up a lot of space. You can paint the enclosures to match your Ford's interior, and each enclosure already has a cutout for the RetroSound speaker, so they'll just pop right in.
Important Note: These enclosures fit in 1964-66 Ford Mustang coupe; they will not work in Mustang convertibles.
