Customer Reviews (4.7 / 5 · 3 reviews)

Alexander ★★★★★ Nov 5, 2026

Slid this under the passenger seat of my Civic and it barely takes up any room, which was my main worry. The 20Hz-150Hz range gives real depth on kick drums without that muddy boom, and it runs clean off the factory head unit.

Scarlett ★★★★★ Nov 3, 2026

Slid this under the passenger seat of my truck and it actually fits without stealing legroom, which I was worried about. The bass hits surprisingly deep for an 8-inch, and the 20Hz-150Hz range handles everything from rap to rock cleanly.

Kevin K. ★★★★☆ Nov 4, 2026

For an 8-inch sub it hits surprisingly low, and the 20Hz-150Hz range really shows on hip-hop tracks. Only gripe is the bass gets a little muddy at high volume, but for a compact under-seat setup it's solid.
