Richard ★★★★★

Fits perfectly on my MP 300 D4, and the steel mesh feels solid without adding too much weight. Install was straightforward with the pre-drilled mounting holes—looks clean behind the grille. Glad I grabbed this for the extra protection.

Madison A. ★★★★★

The grille's steel mesh is surprisingly rigid, and it bolts onto my MP 300 D2 without any fuss. It really anchors the sub and keeps the cone protected without messing with the sound.

Hannah I. ★★★★★

I was worried a grille this stiff would rattle at high volume, but the steel mesh sits dead silent on my Mille Pro, and the 300mm fit is spot-on. The open design keeps the cone visible without sacrificing protection, which is exactly what I wanted for the trunk setup.
