Glue it & Screw It™ Custom Enclosures

Looking for the perfect bass solution? Our Custom Subwoofer Boxes are precision-cut on a CNC machine to match your exact specs, then shipped flat-packed so you can assemble them yourself with just glue and screws. This “glue it and screw it” approach gives you the best of both worlds: pro-level performance with the satisfaction of building it yourself.

Each enclosure is designed specifically for your subwoofers with no guesswork and no compromises. Whether you're running a single 10” or a pair of 12s, we calculate the airspace and tuning to get the most out of your system. Because the box is custom-cut for your needs, you get tighter bass, cleaner sound, and far less distortion than with generic enclosures.

Assembling your box is simple. Every panel arrives labeled and cut with precision, so everything fits together perfectly. Once it’s glued and screwed, the result is a rigid, airtight cabinet built to perform and last. No rattles or leaks, just powerful, accurate bass.

If you're serious about sound, don't settle for one-size-fits-all. Get a Custom Subwoofer Box from GP Car Audio that’s built specifically for your gear and your vehicle.
