Z12AB 12 inch active subwoofer with cables and remote
The Z12AB delivers 250 W RMS (1000 W max) through a 12 inch (300 mm) driver in a purpose-built ported enclosure. The trapezoidal cabinet reduces standing waves for cleaner bass, and the built-in Class A/B amplifier is tuned specifically to the driver, with an efficient heat sink for reliability.
High-level inputs allow direct connection to OEM head units, with Auto Turn-On activating the subwoofer as soon as a signal is detected. Low-level RCA inputs are also included for compatibility with aftermarket head units and processors.
Bass Remote Control Included
A bass remote control is included in the box. It connects via a 5-metre cable, letting you adjust bass level from the driver's seat without reaching the unit.
Complete Installation Kit
The included wiring kit contains everything needed for a straightforward install: 5-metre power wire, 1.2-metre ground wire, 5-metre RCA wire, and 5-metre remote wire. Power and ground wires come pre-fitted with cable lugs and a fuse.
Multiple Size Options
The Z-Series active enclosure range covers three sizes to suit different vehicles and boot spaces: the Z8AB (8 inch, 125 W RMS), the Z10AB (10 inch, 200 W RMS), and this Z12AB (12 inch, 250 W RMS).

About the Phoenix Gold Z12AB
From our tech experts at CEN
An active Phoenix Gold subwoofer, 12 inch, with the amplifier built in, rated at 250w RMS.
Who it suits
Drivers who want bass without finding space for a separate sub, amp and box.
Our tech experts advise
It still needs a fused feed from the battery and a signal source, and level and crossover want setting against your existing speakers so it blends. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: Do I need an amplifier for this subwoofer?
A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.
Q: What does RMS power mean?
A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.
Q: Can CEN build or supply an enclosure and fit everything?
A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.
Q: Does the Phoenix Gold Z12AB need a separate amplifier?
A: No. The Z12AB is an active subwoofer with a built-in Class A/B amplifier rated at 250 W RMS and 1000 W max, tuned to the 12 inch driver.
Q: Can the Z12AB connect to a factory head unit?
A: Yes. It has high-level inputs for direct connection to OEM head units, with auto turn-on when a signal is detected, as well as low-level RCA inputs.
Q: Is a wiring kit included with the Z12AB?
A: Yes. The wiring kit includes a 5 metre power wire, 1.2 metre ground wire, 5 metre RCA wire and 5 metre remote wire, with lugs and a fuse pre-fitted to the power and ground wires. A bass remote with a 5 metre cable is also included.
