Next-Level Audio Installation
Building an amp rack for show points and big bass
here was a time when building out your truck’s audio system meant adding some quality audio components and calling it a day. But now that’s just the tip of the iceberg for show trucks—and lots of daily drivers. Many truck owners and builders are taking several extra steps to ensure their truck stands out in a crowd, not only with big bass, but with the presentation as well.
Recently, we were out at Audiotistics in Victorville, California, and were intrigued by all the high-caliber builds happening. One such vehicle was a Ram that already had some 12-volt upgrades completed by the shop but was back for a full audio rebuild.
The head unit was pretty easy; Tim Wepprecht and the crew updated the double-DIN hole with a new Kenwood eXcelon unit. The component speakers (mids and highs) were already replaced in the last go-round. The big change taking place when we discovered the truck was the finishing stages of a giant “blowthrough” box that was pretty much bulletproof even before the spray-on bedliner treatment and which took up about half the bed. Housed in the behemoth box are four 12-inch subwoofers from Shok Industries.
The last aspect of the build—and the one we were interested in following—was the amp rack, which would be located under the rear seat. As is the case with many crew cab trucks, the seatbacks are mounted directly to the cab wall, while the seat bottoms flip right up. So while the sub box opening would be hidden, the area where the amps would be mounted is easily accessible. This is the area Audiotistics would take to the next level.
Amp racks take on many shapes and sizes, depending on where they are mounted. While this one would be pretty flat and straightforward, that didn’t stop Tim and the crew from adding all kinds of tricks and details. Follow along to see what it takes and let them know if you’re looking for something similar in your truck.
1. Audiotistics is located in Victorville, California, just a hop, skip, and two jumps from Truckin headquarters. We arrived at one of the nicest showrooms we’ve seen and knocked out the install and amp rack build in a couple of days.
2. Some of the high-end components we’re using include the Kenwood DDX 6903S with Apple CarPlay in-dash touchscreen along with four 12-inch Shok Industries subwoofers and a Full Throttle FT-1100 battery.
