7512-44 12" Competition Subwoofer + dB13 Amplifier & Amp Kit

This bundle steps up from the 55 Series into MTX's 75 Series competition line, pairing the 7512-44 with a Rockville dB13 mono amplifier and RWK41 wiring kit. The 7512-44 is a 12 inch dual voice coil subwoofer rated for 750 watts RMS and 1,500 watts peak at 4 ohms, built with a cast aluminum basket and a glass fiber cone for the rigidity and low weight that high-output SPL builds need. Its Inverted Apex surround and progressive, layered spider eliminate break-in time and push higher volume displacement, while a dual-layer thermal system combining Spider Plateau Venting and an integrated t-yoke heat sink keeps the voice coil in check under sustained high power.

The dB13 is sized to match, delivering 450 watts RMS at 4 ohms from an 80 amp Maxi fuse, well above what a typical mono amp in this class provides. It includes a fully adjustable bass EQ, a subsonic filter, and a remote dashboard subwoofer control for tuning output without leaving the front seat. The RWK41 kit supplies 4-gauge power and ground cable plus copper RCAs sized to carry that output cleanly. This pairing is built for anyone who has outgrown a standard subwoofer and want the headroom to push it hard.
