Customer Reviews (4.2 / 5 · 5 reviews)

Hannah ★★★★★

Fit perfectly on my car's existing speaker mounts without any drilling or modifications needed. The FlexMount rings feel solid and premium, not like cheap plastic like other adapters I've used.

Aurora Y. ★★★★★

Finally, a mounting solution that doesn't require a second pair of hands. The twist-lock mechanism on this adaptor made installing my 4" midrange in the Porsche dash a one-person job.

Madison ★★★★★

This mounting system held my 4-inch midranges solidly in the door panel — the single-turn lock mechanism is clever and feels precise. Installation took less than 20 minutes once I had the right tools.
