RetroSound サーフェスマウント 2ウェイスピーカー 4インチ ペア販売 20W RMS

Took a chance on these for my classic's dash setup, and the 20w RMS per pair is plenty punchy for a small cab. The surface-mount brackets made installation straightforward, and they fit snugly under the dash without rattling even at higher volume.

Installed these under the dash in my old truck and the sound quality is a huge improvement over the stock single speaker. The 20w RMS handles classic rock nicely without distortion.

The grille and housing feel solid enough to survive my bumpy backroads, and the 4-inch size fits perfectly tucked under the dash without blocking my knees. Sound is clear at low volume, which is exactly what I wanted for cruising without blasting my ears.
