Customer Reviews (5.0 / 5 · 5 reviews)

Ruby ★★★★★

Installed these in my truck’s front doors to replace some blown factory speakers, and the clarity at higher volumes surprised me—even with just the stock head unit driving them. The oval shape fit perfectly into the existing 5x7 cutouts with no adapter needed.

Aurora ★★★★★

The 70W RMS rating is spot on—these 5x7s handle my daily commute without breaking a sweat, and the sound stays clean even at higher volumes. Installation was straightforward for an oval format pair, and the bass response is tighter than I expected from a coaxial kit.

Amelia ★★★★★

Cranked them up on the highway and the 70W RMS handling held steady without any distortion even at higher volumes. The oval 5x7 shape dropped right into the factory mounts, so installation was a clean swap with zero cutting. These coaxials fill the cabin nicely for the price, no complaints here.
