The DMD124SH Shallow Mount Subwoofer from Diamond Audio is the ideal solution for car audio systems where space is limited but powerful bass is still a priority. Designed for tight installations in trucks, cars, and custom enclosures, this 12-inch shallow subwoofer delivers impressive low-frequency performance with an ultra-slim mounting depth of just 3 inches.
Part of the proven DMD Series, the DMD124SH is engineered to perform best in sealed enclosures, delivering tight, controlled bass that rivals traditional full-size subwoofers while taking up significantly less space. Its dual 4-ohm voice coil configuration provides wiring flexibility, making it easy to match with a wide range of amplifiers for optimal power delivery.
For maximum bass output and efficiency, Diamond Audio recommends using two DMD shallow subwoofers in a compact 1-cubic-foot enclosure. This setup allows you to achieve deep, impactful bass without sacrificing valuable cargo or interior room.
Whether upgrading a daily driver or building a custom space-saving system, the DMD124SH offers big bass performance in an ultra-shallow, installer-friendly design built for modern vehicles.
