Crisp quality highs with rich sound

The following review is for GX9638, which is a part of the bundle you are viewing.

I just installed these in the front doors with GX-628 in the rear doors, and an amplifier/subwoofer behind the rear seat in our 2023 f150. The sound is awesome, and the only negative thing is that the software in the Ford stereos is limited to adjusting ranges between the regular highs, mids, and lows. Regardless, these speakers are tremendously richer in sound and clarity. You won't regret this purchase!!

The following review is for GX9638, which is a part of the bundle you are viewing.

Harness had male terminals. Needed female terminals to plug into factory connector. Also had to cut screw length. And speaker to adapter screw holes did not line up.
