Car speaker ACV Spacer 165 mm (shallow mount depth 7 mm) set

The ACV Spacer 165 mm car speaker set is a compact two-way solution designed for installations that require an ultra-shallow mounting depth. With a 165 mm diameter and only 7 mm shallow mount depth, this set is suitable for replacing or upgrading factory speakers in vehicles where space behind panels is limited. The kit includes matched components for a pair installation and is intended to provide a practical, space-saving option for sound system retrofits and custom dash or panel applications.

Advantages

The shallow 7 mm mounting depth allows installation in narrow cavities and behind tight door panels without major modifications. The 165 mm diameter follows common OEM dimensions, simplifying replacement of many factory speaker locations. Components are matched for pair mounting to maintain consistent tonal balance across left and right channels. The design emphasizes fitment flexibility and practical compatibility with common car audio systems.

Suitable for

• Replacement of factory 165 mm speakers in vehicles with limited mounting depth
• Retrofit installations in door cards, custom dashboards, or rear parcel shelves with shallow cavities
• Upgrades where low-profile speakers are required to avoid interference with window mechanisms or trim

Key specifications

• Speaker diameter: 165 mm
• Mounting depth: 7 mm (ultra-shallow)
• Set composition: components for pair mounting
• Intended use: car audio, shallow-fit installations

How to use

Measure the existing speaker cutout and available rear clearance to confirm compatibility with the 165 mm diameter and 7 mm mounting depth. Remove the factory speaker and mounting hardware, then connect the speaker terminals to the vehicle wiring, observing polarity. Position the spacer and speaker assembly into the cutout, ensuring a secure fit and that wiring is not pinched. Reinstall trim and test the speaker with a low volume check before normal use.

Usage recommendations

For best results, verify speaker depth and mounting hole alignment before final installation. Use correct polarity and moderate amplifier gain to avoid overloading shallow-mount drivers. If door cards require additional support, consider using lightweight reinforcement or factory-style retainers to ensure stable long-term fitment.
