This MTX Audio Restored Automotive package, model 5512-44+dB11+RWK81+RBS12+K1, contains an MTX 5512-44 12" car subwoofer, a Rockville RBS12 single-subwoofer vented enclosure, a Rockville dB11 mono Class-D amplifier with bass remote, and a Rockville RWK81 8-gauge wiring kit. It also includes RCA wiring, 10 metal drywall wood screws, 12 feet of 14 AWG blue speaker wire and 2 spade terminals.

The subwoofer's dual 4-Ohm voice coils are rated at 400 Watts RMS and 800 Watts peak; recommended amplifier power is 200-400 Watts RMS. Frequency response is 26Hz to 130Hz, with 85.7 dB sensitivity, a 2" dual voice coil and a 56 oz magnet. Mounting depth is 6.188", cutout diameter is 11.125", and displacement is 52.46 cu in.

Recommended net enclosure volumes are 1.0 cu ft sealed or 2.32 cu ft vented. Its inverted apex surround increases surface area for displacement and SPL; spider plateau venting directs cool air toward the coil. A progressive suspension controls high-power excursion, while a radial ribbed T-yoke helps dissipate heat and reduce distortion. An installation sheet is available.

The RBS12 is a 2.6 cu.ft SPL enclosure designed for higher output than many other enclosure types; a mounting and wiring kit for one subwoofer is included. The dB11 is specified as a 1400w/700w RMS mono amplifier. Its CEA-compliant ratings, measured below 1% distortion, include 350 Watts x 1 channel at 2 Ohm and 220 Watts x 1 channel at 4 Ohm, both below 1% THD+N.

The RWK81 kit includes twisted-pair copper RCA cable and translucent blue power cables. The supplied 14 AWG wire is described as offering a cleaner signal than 16 gauge. UPC: 613815740964. SKU: sku-269885803. The subwoofer and package title also specify 800W/400W.
