About the Audison AV 5.1k
From our tech experts at CEN
A monoblock subwoofer amplifier from Audison’s range.
Who it suits
Anyone driving a subwoofer that needs real, controlled power.
Our tech experts advise
Matching matters more than headline watts, and gains want setting with a meter rather than by ear. It also needs a fused feed from the battery on the correct gauge. Installation and tuning are 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 is the power split on the Audison AV 5.1k?
A: Two Class A channels at 75W RMS each into 4 ohms, two Class AB channels at up to 250W RMS each into 2 ohms, and one Class D subwoofer channel at 1000W RMS into 2 ohms, for 1650W total.
Q: Can the AV 5.1k take speaker-level inputs from a factory head unit?
A: Yes. It has both pre-amp and speaker-level (high-level) inputs, with selectable automatic remote turn-on from the speaker outputs.
Q: Does the AV 5.1k have a remote subwoofer level control?
A: Yes. The specification lists remote subwoofer volume control with an adjustment range of -50 to 6dB.
