MTX Terminator Dual 12 Subwoofer System + Rockville RWK81 & RXC2D Bundle

This bundle adds a Rockville RWK81 8 gauge wire kit and an RXC2D 2 Farad stiffening capacitor to the Terminator TNP212D2 subwoofer and amplifier package, covering both the connection to the battery and the extra electrical support that heavy bass systems can need. The TNP212D2 puts two 12” Terminator subwoofers into a sealed 5/8” MDF enclosure rated at 1200W peak and 400W RMS at 2 ohms, powered by a matching Class D monoblock amplifier with selectable bass boost.

The RWK81 wire kit runs 8 gauge translucent blue power cable alongside 100% copper RCA cables and a 60 amp AGU fuse, giving the amplifier a clean, properly sized path to the battery. The RXC2D capacitor sits between the battery and amplifier to buffer voltage during heavy bass hits, using IC controlled circuitry to manage charging and discharging while a built-in LED digital voltage meter shows the current state of your electrical system at a glance. Negative polarity protection guards against miswiring during install, and included Lucite mounting brackets and hardware make it straightforward to secure. Together, the wire kit and capacitor round out the subwoofer package with the electrical support a high-demand amplifier setup benefits from.
