About the Zapco ST-2000XM III
From our tech experts at CEN
The Zapco ST-2000XM III is a mono Class D subwoofer amplifier rated at 2000W at 1 ohm, 1450W at 2 ohms and 1000W at 4 ohms. Part of the ST-X III range, it features variable gain, subsonic filter, bass boost, electronic crossover and phase controls. The Zapco ST-BR dash-mount remote level control is included in the box.
Who it suits
This amp suits enthusiast and competition builds that need high subwoofer output with precise onboard tuning. The strappable design allows two units to drive a single voice coil where more headroom is required. Those needing less power may prefer the Zapco HB 501D II at 300W.
Our tech experts advise
Overall dimensions are 160 x 58 x 475 mm, so plan boot space carefully and leave clearance around the unit for airflow. Confirm your subwoofer's impedance and power handling before deciding on a wiring configuration. Installation is priced per vehicle; visit our car audio installation page to find out more.

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 Zapco ST-2000XM III produce?
A: The ST-2000XM III is rated at 1 x 2000 watts at 1 ohm, 1 x 1450 watts at 2 ohms and 1 x 1000 watts at 4 ohms.
Q: Does the ST-2000XM III come with a bass remote?
A: Yes. It has a dash mount remote gain control. Zapco includes the ST-BR remote level control with its ST-X mono amplifiers.
Q: Can two ST-2000XM III amplifiers be linked?
A: Yes. The ST-2000XM III is strappable, so a pair of amps can be used on a single voice coil.
