2020 GMC Sierra SCA Performance Armed Forces Edition The factory panels were removed and our new speaker plates added. The Audiofrog GB speakers were a huge upgrade. Sound deadening was used on the door panels. The Audiofrog GB woofers were mounted on a custom trim panel. Our fabricators created this plate to mount the amplifiers on. The space behind the rear seats were perfect for mounting the amplifiers. We added a painted insert to the plate for the woofers. The painted accent plates on our custom plates complimented the interior nicely. The factory radio was retained as the source unit. The custom enclosure features red accent lighting. JL Audio’s 13TW5’s were chosen for low end reinforcement.
