Two beveled PVC spacer rings add angled clearance for 6.5-inch speakers in automotive, marine or custom audio installs
Each ring is precision-cut with a 148mm mounting hole diameter, ensuring secure compatibility with most aftermarket and OEM 6.5in speakers. The beveled design features a 38mm max depth that tapers to 19mm, allowing angled speaker positioning for better sound projection. Constructed from rugged PVC, the rings resist vibration, heat, and moisture for long-lasting performance in automotive or marine environments.
These spacers replace the need for custom fabrication when factory speaker locations are too shallow for aftermarket drivers. The 38mm to 19mm tapered profile clears door panels and window tracks where a flat adapter would interfere. The jump is worth it when the speaker magnet or frame depth exceeds the available cavity and angled mounting improves aim toward the listening position.
Installation uses the existing speaker mounting screws through the 148mm opening; no adhesives or special tools are required. The two-pack covers a standard front-door pair, saving time on dual installs. Builders who need a second card for rear doors or a different bolt pattern should verify hole spacing before ordering.

The precision-cut mounting hole diameter is 148mm (5-13/16 inches), ensuring secure compatibility with most aftermarket and OEM 6-1/2 speakers.
Mount the ring between the speaker and door panel using the 148mm hole; the tapered depth runs from 38mm down to 19mm, so orient the thicker 1-1/2 inch side outward for correct angled projection.
The rugged PVC construction resists vibration, heat, and moisture for long-lasting performance in automotive, marine, or custom audio setups without requiring scheduled replacement.
