The high-density ABS material feels rock solid, so I'm not worried about vibrations rattling it loose over time. Cutouts lined up perfectly with my 6.5s and the 1.38-inch tweeter, making the whole swap a straightforward afternoon job.

The high-density ABS build feels rock solid, and the fact that it lets me fit a 6.5-inch speaker plus a 1.38-inch tweeter into the factory 6x9 hole is exactly what I needed. Fit was snug and clean, no rattles after a week of bass-heavy driving.

Finally got my 6.5s and tweeters mounted where the old 6x9s sat, and the ABS adapter fit the opening without any trimming. The dual cutouts are positioned well, but I wish the screws were included since I had to dig through my hardware bin for matching ones.
