2022 Ford Explorer The amplifiers, integration module and Stinger battery are all mounted in the storage area under the floor in the rear of the vehicle. The two JL Audio flagship subwoofers are suspended in a ported enclosure, which sits just above the amplifiers and other equipment. Because the JL Audio W7 subwoofers are so powerful, our expert fabricators added bracing to the custom enclosure built to house the drivers. As with all our installations, big or small, we take the time to make sure all wiring is safely run. Our technicians carefully ran 0 AWG wire from underneath the hood back to where the amplifiers are housed. The rear speakers were replaced with Alpine 6.5-inch component speakers, similar to the ones replaced in the front. A separate set of 2.5-inch Alpine midrange drivers were installed in the middle of the front doors. Our technicians fabricated mounting brackets for the Alpine tweeters at the top of the doors near the door handles. The vehicle’s front speakers were replaced with Alpine 6X9 component speakers. We used SoundShield sound deadening material to help reduce sound transfer in the vehicle cabin.
