The Audison SR 4.300 V2 is a compact four-channel Class D amplifier delivering 300W RMS total, designed to fit where larger amps cannot.

Audison D-Class Technology

Audison's own ADT amplification keeps the unit small without compromising audio quality. The extruded aluminium chassis features rounded corners, making installation straightforward even in tight spaces. Each channel delivers 85W RMS into 4 ohms. A built-in crossover is included for flexible system setup.

Simple OEM Integration

High-level inputs with USS (Universal Speakers Simulator) allow a clean connection to factory head units. Upgrade your sound without touching your existing stereo. The SR 4.300 V2 sits within the wider Audison SR range, which spans mono to five-channel configurations.

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.
