About the Phoenix Gold ZXM700.5
From our tech experts at CEN
The Phoenix Gold ZXM700.5 is a Class D 5-channel mini amplifier from the ZX Series, delivering over 700W RMS from a chassis measuring just 202 × 83.1 × 34.8mm. It runs four speakers and a subwoofer simultaneously, rated at 4 × 60W plus 230W at 4 ohm. A remote bass knob for the sub channel is included.
Who it suits
This amp suits anyone wanting a complete 5-channel setup — four speakers plus a subwoofer — without sacrificing much boot or under-seat space. It accepts both high-level and low-level inputs, so it works with factory head units as well as aftermarket sources. For a standalone mono subwoofer amplifier, consider the Phoenix Gold ZXM500.1.
Our tech experts advise
At 202mm long the ZXM700.5 fits under most seats or in tight boot spaces. High-pass and low-pass filters on the four main channels (40–420Hz, 12dB) remove the need for a separate crossover. The quick-connect terminal for power, ground and remote speeds up installation; fitting costs vary by vehicle, so visit our car audio installation page for details.

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 ZXM700.5 produce?
A: Rated at 14.4V with less than 1% THD, it delivers 4 x 60W + 230W at 4 ohms, 4 x 100W + 350W at 2 ohms, or 2 x 200W bridged at 4 ohms on the speaker channels.
Q: Can the ZXM700.5 power a whole system?
A: Yes. It has four speaker channels with HP/LP filters (40 – 420Hz, 12dB) and a sub channel with a 24dB low-pass filter and remote gain control.
Q: How big is the ZXM700.5?
A: It measures 202 x 83.1 x 34.8mm.
