What kind of subwoofer does this fit?
This enclosure is precision-built for a single shallow-mount 12" round subwoofer. The cutout diameter is exactly 11.00" and it is engineered specifically for low-profile, slim drivers requiring a maximum mounting depth of 4.75".

Will it fit in my vehicle?
Yes, it features an ultra-compact, space-saving wedge downfire footprint designed to slip into extremely tight spaces. Its shallow depth (7.25" bottom depth tapering to 6.25" top depth) makes it an excellent solution for truck cabs, behind or under seats, or inside compact cargo spaces where every inch matters. The exact external dimensions are 16.25" W x 13.50" H x 7.25" D1 (Bottom) x 6.25" D2 (Top).

How is the performance and wiring?
This enclosure features a specialized downfiring configuration that naturally loads the subwoofer against your vehicle's floor pan, increasing structural acoustic coupling to deliver deep, rich, and highly localized bass reinforcement. The downfire alignment also keeps the fragile subwoofer cone completely concealed and protected from shifting cargo. The airtight sealed chamber provides incredibly tight, punchy transients with great power handling. It comes equipped with a high-grade speaker terminal cup featuring gold-plated binding posts for secure, reliable wiring connections.

Grille-ing Me Softly: A 30-Minute Makeover Adventure
Color: Single Slat Gloss Black, Size: 2019-2022 G20, Color: Single Slat Gloss Black, Size: 2019-2022 G20
Installing this grille was a breeze! It took me about 30 minutes, even with a minor hiccup of having to uninstall it to add the front camera panel I initially forgot. The grille feels incredibly durable, made from plastic that matches the quality of the OEM version. Plus, it gives my car a fresh, youthful look. Highly recommend for a quick and stylish upgrade!

Good quality
The material is very sturdy and came rolled up. Left it on the kitchen counter for a week with weight on it to get it close to flat. When installing there are about 3 predrilled holes in the mat. You have to drill into the floor board to install provided clips which is fine, but I had extra clips so I drilled additional holes in both sides to get the malt flush. I like the mats.

Fit perfectly!
The only complaint was they are shipped rolled up. Have to let them set out in the sun all day to flatten out. They're not rubber! More like a WeatherTech floor mats in a vehicle. Had plastic rivets to mount them to the floor, but wasn't drilling holes in a brand new buggy......

I was kind of skeptical to purchase this grille but ended up pulling the trigger on it , installation was not that hard, the hardest part is to swap the camera attachment to the non camera one , after that everything was a breeze, looks great and the material quality is no different from oem, will do another review after couple of months to give more info on the durability and paint fading ( if there’s any, hope not)
