2x Phoenix Gold GX12D4 12" Subwoofers, Z6001i Amplifier, Dual Sealed Box & Wiring Kit
Build a powerful twin-subwoofer system with this complete Phoenix Gold bass package. The kit includes two GX12D4 12-inch dual voice-coil subwoofers, a Phoenix Gold Z6001i Class-D monoblock amplifier, a dual 12-inch sealed MDF enclosure and a Connects2 PRO-FOUR 4AWG amplifier wiring kit.
Each GX12D4 has two 4-ohm voice coils. Wiring each subwoofer’s coils in parallel creates 2 ohms per subwoofer. Connecting both subwoofers in parallel creates a final 1-ohm load, allowing the Z6001i amplifier to supply 600 watts RMS across the pair.

Recommended System Configuration
Wire the two 4-ohm voice coils on each GX12D4 in parallel to create a 2-ohm load per subwoofer. Connect both 2-ohm subwoofers in parallel to create a final 1-ohm load at the amplifier.
At 1 ohm, the Z6001i supplies 600 watts RMS across the two subwoofers. The subwoofers have a combined nominal power handling of 800 watts, providing suitable power-handling capacity for the amplifier.
Correct voice-coil wiring, amplifier gain, crossover and subsonic-filter adjustment are essential. Professional installation is recommended.
