5515-44 Pair + KRYPTON-M2 + RWK41 + RDV15

This dual 15-inch car subwoofer system combines two 5515-44 subwoofers, a mono amplifier rated at 750W RMS at 1 ohm, a dual 15-inch vented enclosure, and the accessories for a bass-focused installation. Each subwoofer handles 400W RMS, for 800W RMS combined handling, while the amplifier's 750W RMS output sits within the pair's combined recommended range of 400W to 800W RMS when the voice coils are wired for a 1-ohm load. Dual 4-ohm voice coils, an Inverted Apex Surround, progressive suspension, and Spider Plateau Venting support cone movement, lower distortion, and heat management during extended playback. The amplifier adds a clipping-indicator bass remote, digital voltage display, adjustable low-pass and subsonic filters, and bass EQ. The package also includes a 4-gauge wiring kit with RCA cables, a dual 15-inch vented enclosure, 20 feet of blue 14 AWG speaker wire, 20 metal drywall/wood-type screws, four spade terminals, mounting screws, and a tested-power birth sheet. Check vehicle fit, electrical requirements, and final speaker wiring before installation.
