⚠️ IMPORTANT: DIGITAL PRODUCT ONLY
This is a custom digital engineering and blueprint service. Product images are shown exclusively as examples of our prior work. No physical wooden box or enclosure will be manufactured or shipped to your address.
The Precision Engineering Difference
Executing a blow-thru build means moving a massive amount of bass from the truck bed straight into the cabin. With this service, you provide the maximum available dimensions of your truck bed along with the exact size and placement of your cab-to-bed cutout window. We engineer a high-output blueprint designed to fit your bed constraints while ensuring the port aligns perfectly with the cutout dimensions you supply. The port itself is mathematically sized and tuned strictly according to your subwoofer and enclosure specifications, guaranteeing your drivers are in the exact environment they require to perform flawlessly without choking or unloading.
📦 What You Receive in Your Digital Blueprint Package:
Every custom design is compiled into a high-resolution, easy-to-print PDF package containing:
- Step-by-Step 2D Blueprints: Detailed structural schematics featuring exact dimensions for every independent angle and panel face.

accurate timeline, very detailed layout, and found specs on a older not as popular woofer great job all the way around
Great design
This thing looks amazing!!! I've not gotten started on the build yet. But every time I look at the blue prints I start getting excited about it!!! I'll definitely be posting about the build when I get started, during the entire build, after completion, and most definitely test and tune day!!! Stay tuned!!!
Three designs in and I've yet to be disappointed. EZ DB'S has provided me with awesome designs with a fast turn around time.
Amazing! Just as everyone said it would be that recommended EZ DB’s Designs. The person that assisted me was very thorough. This enclosure was definitely on the tricky side. I highly recommend this company to everyone. Especially if you want to be loud.
