OPTION AIR-D1 1-Channel Monoblock Amplifier for Subwoofer
Compact powerhouse for subwoofers: The OPTION AIR-D1 is a powerful mono amplifier (Class-D) designed specifically for powering subwoofers. Despite its small size, it delivers impressive pressure and provides a rich bass foundation in your vehicle.
Ultra-compact design: Thanks to its extremely small dimensions, this "micro amplifier" can be installed almost anywhere - ideal for modern vehicles where space is scarce under the seat, behind the glove box or in side panels.
Perfect for original radios: Equipped with high-level inputs and an auto turn on function, the power amplifier can be easily integrated into existing factory systems. A separate remote cable is not required as the amplifier detects the signal directly.
High-efficiency Class-D technology: The modern digital circuit guarantees minimal power consumption while at the same time very low heat generation. This ensures reliable performance and protects the battery of your vehicle, even during longer listening sessions.
Precise sound adjustment: With the integrated low-pass filter (low pass), you can precisely tune the cut-off frequency to your subwoofer. This prevents unclean frequencies in the bass range and maintains a perfectly harmonious sound with your rest of the speakers.

FAQs
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.
