2x Phoenix Gold RX212D 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 RX212D 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 RX212D has two 4-ohm voice coils. Wiring each subwoofer’s coils in parallel creates 2 ohms per subwoofer. Connecting both subwoofers in parallel produces a final 1-ohm load.
The Z6001i can produce up to 600 watts RMS at 1 ohm, while the two subwoofers handle 400 watts RMS combined. The amplifier gain must therefore be correctly limited to prevent the subwoofers from receiving excessive power.

12SUBSDB Dual 12" Sealed Enclosure
The included dual enclosure is constructed from MDF and finished in black acoustic carpet. It provides two mounting positions for the included 12-inch subwoofers and uses a sealed design for controlled bass response.
This is a separate universal dual 12-inch enclosure supplied as part of the package. It has not been specifically manufactured or acoustically tuned exclusively for the RX212D subwoofers.
- Designed to accommodate two 12-inch subwoofers
- Dual sealed enclosure design
- Durable MDF construction
- Black acoustic carpet finish
- Integrated sound-absorbing foam
- Includes two 45cm lengths of 16AWG pure-copper speaker cable
- Product dimensions: 77 x 32 x 36cm
- Carton dimensions: 79 x 34 x 38cm
Connects2 PRO-FOUR 4AWG Amplifier Wiring Kit
The PRO-FOUR is a heavy-duty 4AWG installation kit containing the main power, ground, signal and speaker cables required to connect the amplifier and subwoofer system.
- 4AWG amplifier installation kit
- Rated up to 1000 watts
- 5.2m red power cable with fitted 10mm ring terminal
- 0.8m black ground cable with fitted 10mm ring terminal
- 5m blue and white 2.5mm speaker cable
- 5m RCA cable with integrated remote wire
- Gold-plated RCA connectors with straight and angled ends
- Waterproof nickel-plated Mini-ANL fuse holder
- 80A Mini-ANL fuse
- Two fork terminals with coloured covers
Recommended System Configuration
Wire the two 4-ohm voice coils on each RX212D 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 is capable of producing 600 watts RMS. The two RX212D subwoofers handle 400 watts RMS combined, so the amplifier output must be correctly restricted to no more than the combined power rating of the subwoofers.
Incorrect gain or bass-boost settings may damage the subwoofers. Professional installation and calibration are strongly recommended.
