A client came to Audio Designs and Custom Graphics in Jacksonville in search of a Toyota 4Runner enclosure and subwoofer. We had a look at the vehicle and proposed one of our Phantom Fit custom enclosures that would fit nicely into the right rear corner of the cargo area. After selecting the perfect subwoofer for the system and an amp to drive it, we provided a quote to the customer. He loved the plan, so we scheduled an appointment to start work.
Toyota 4Runner Enclosure
The first step in creating this enclosure was to do a rough air volume calculation to ensure that the Audiomobile GTS2110 subwoofer we selected would have adequate airspace to perform as intended. Too many shops start building an enclosure that looks good but doesn’t perform well. Once we had the basic shape down, we began making measurements for the enclosure and drawing the components in our CAD software.
We construct our enclosures using layers of 3/4-inch MDF stacked on top of each other. This process is called Stack-Fab, and produces a very rigid enclosure. The best part is that we can recreate the enclosure at any time by loading the design into our CNC machine.
Subwoofer Enclosure Construction
Once we cut each layer of MDF on our CNC machine, we apply a high-strength adhesive to each panel and bond them together. To maximize the performance of the enclosure, we paint in the interior with a thorough coating of fiberglass resin. The resin seals the MDF to ensure it is completely airtight.
The next step is to cut the opening for the subwoofer. We use our router and a circle template to cut the opening, then wrap the enclosure in heavy-duty black trunk liner carpet.
The enclosure fits perfectly into the corner of the trunk and makes use of the factory storage pocket to minimize the overall depth of the system. Access to the AC power port is not affected, but the 12 V accessory jack is concealed.
System Installation and Tuning
With the enclosure in place and the new amplifier wired up, our installation technician ensured that the output of the sub blended perfectly with the remainder of the system and was capable of getting good and loud.
The client returned to Audio Designs and Custom Graphics to experience his upgrade system for the first time. He loved the way the enclosure looked and was thrilled that it did not take up any storage space.
