Description
Need a 2-Inch 4-Bolt Driver in a 6.5-Inch-Class Location?
This SMS Precision adapter gives a compatible 2-inch four-bolt driver a proper mounting interface in a 6.5-inch-class speaker location or fabrication opening. It is made for custom doors, speaker pods, panels, and other purpose-built installations where the driver and the opening were never designed to bolt together on their own.
What It Is
| Product type | Speaker-driver mounting adapter |
|---|---|
| Nominal outer application | 6.5-inch-class speaker location |
| Driver interface | Compatible 2-inch four-bolt driver |
| Sold as | Single adapter unless the product selection states otherwise |
| Fitment | Custom; bolt pattern and available clearance must be confirmed |
Before You Install It
- Confirm the driver bolt pattern, mounting depth, and rear clearance before ordering.
- Check grille clearance, wiring access, and surrounding fabrication geometry.
- Use the crossover and power requirements specified for the selected driver.
- Speaker or high-frequency driver is not included.
This is a fabrication adapter, not a claim that every 2-inch four-bolt driver fits every 6.5-inch-class location. Verify the actual driver and the available space.
