Phoenix Gold RX212D 12" Subwoofer, Z3001i Amplifier, Sealed Box & Wiring Kit Package
Add powerful bass to your vehicle with this complete Phoenix Gold package. The kit combines the RX212D 12-inch dual voice-coil subwoofer with the Phoenix Gold Z3001i monoblock amplifier, a single 12-inch sealed MDF enclosure and a Connects2 PRO-EIGHT 8AWG amplifier wiring kit.
The RX212D has dual 4-ohm voice coils which can be connected in parallel to produce a final 2-ohm load. The Z3001i amplifier can produce up to 300 watts RMS at 2 ohms, so its gain must be correctly limited to match the subwoofer’s 200-watt RMS power rating.

- Rated up to 720 watts
- 5.2m red power cable with fitted ring terminal
- 0.8m black ground cable with fitted ring terminal
- 5m blue and white 1.5mm 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
- 60A Mini-ANL fuse

Recommended System Configuration
Connect the RX212D’s two 4-ohm voice coils in parallel to produce a final 2-ohm load. The Z3001i can produce up to 300 watts RMS at this impedance, which exceeds the subwoofer’s 200-watt RMS rating.
The amplifier gain must therefore be correctly restricted so the subwoofer does not receive excessive power. Incorrect gain or bass-boost settings may damage the subwoofer. Professional installation and calibration are strongly recommended.
