About the Ground Zero GZIA 1500.1
From our tech experts at CEN
A monoblock subwoofer amplifier from Ground Zero, Class D, rated at 1530w.
Who it suits
Anyone adding a subwoofer that needs real power behind it. Ground Zero is a German brand with a strong following in competition and SPL circles, and the amplifiers reflect that.
Our tech experts advise
Matching matters more than headline watts, and gains want setting with a meter rather than by ear. 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 GZIA 1500.1 deliver?
A: It delivers 430W RMS at 4 ohms, 850W RMS at 2 ohms and 1530W RMS at 1 ohm, with 1900W max output (CEA-2006A).
Q: Is the GZIA 1500.1 1 ohm stable?
A: Yes. It is 1 ohm stable and delivers 1530W RMS into a 1 ohm load, which suits dual voice coil subwoofers wired down to 1 ohm.
Q: Does the GZIA 1500.1 come with a bass remote?
A: Yes. A wired bass remote control is included, so you can adjust the bass level from the driving seat.
