CS5768CX

The Crunch CS5768CX is a pair of two-way coaxial speakers that fit both 5x7-inch and 6x8-inch factory openings, the sizes used across most Ford, Mazda, and older domestic door and rear deck locations. One part number covers both cut-outs, so you are not guessing at the bracket pattern before ordering.

Power handling is 125W RMS and 250W peak per pair. A silver alpha-cellulose poly cone produces midrange and midbass with low moving mass, and a 1-inch Neo-Mylar soft dome tweeter handles highs through a passive Butterworth crossover with a 6dB internal slope at 4kHz. Response spans 46Hz to 20kHz, and the extra low-frequency reach compared with smaller drivers is what makes these worth doing in door locations where midbass carries the music.

At 88dB sensitivity they run well off a factory head unit and scale up cleanly with an amplifier. The UV-resistant rubber surround takes sun and moisture, high-temperature adhesive holds the cone-to-surround joint under sustained output, and the anti-resonant stamped steel basket keeps frame flex and ringing out of the sound. A pure copper voice coil on a Kapton former manages heat with over-coil cooling.

Mounting depth is 2.13 in, shallow enough for door skins with window mechanisms behind them, and the 5.67 in cut-out matches factory patterns. Outside dimensions are 8.60 x 5.56 in without a grille, since these usually sit behind an OEM panel. Textured ABS gaskets seal the mounting surface and spade terminals speed up wiring.
