About the Phoenix Gold ZXM600.3
From our tech experts at CEN
A 3-channel amplifier from Phoenix Gold.
Who it suits
Drivers whose speakers have outgrown the head unit.
Our tech experts advise
Matching matters more than headline watts, and gains want setting with a meter. It needs a fused feed from the battery on the correct cable gauge. 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: How do I choose the right amplifier for my speakers or subwoofer?
A: Match the amplifier's RMS output per channel to the RMS handling of your speakers or subwoofer at the same impedance. The Specification tab lists the power figures. If in doubt, contact CEN with your setup and we will recommend a match.
Q: What wiring do I need to install this amplifier?
A: You will need an amplifier wiring kit sized to the amplifier's power draw, typically including power and earth cable, a fuse, RCA leads and a remote wire. CEN stocks complete wiring kits, and the amplifier's fuse rating is the guide to the cable gauge required.
Q: What class of amplifier is this and does it matter?
A: Class D amplifiers are compact and efficient, ideal for subwoofers and modern installs. Class AB designs are traditionally favoured for outright sound quality on mid and high frequencies. The class is listed in the Specification tab where provided.
Q: Will an amplifier work with my factory head unit?
A: Yes, in most cases. If your head unit has no RCA outputs you will need a line output converter to feed the amplifier a clean signal. CEN stocks line output converters and can advise the right one for your vehicle.
Q: Can CEN install this amplifier?
A: Yes. CEN offers professional amplifier installation from our Nottingham premises, including secure mounting, wiring and setup. Contact us to book.
Q: How much power does the Phoenix Gold ZXM600.3 produce?
A: Rated at 14.4V with less than 1% THD, it delivers 2 x 75W + 230W at 4 ohms, or 2 x 125W + 350W at 2 ohms.
Q: Can the ZXM600.3 run speakers and a subwoofer together?
A: Yes. It has two channels for a front speaker pair with HP/LP filters (48 – 480Hz, 12dB) and a sub channel with a 24dB low-pass filter, plus 0 – 18dB bass boost.
Q: Does the ZXM600.3 accept high level inputs?
A: Yes. It supports high and low level inputs, with an input sensitivity range of 0.2V – 10.0V.
