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.

Elizabeth D. ★★★★★

Installed this in my trunk to drive a single 12" sub and the 350w RMS rating is spot on—my bass hits clean without distortion even at higher volumes. The compact size made it easy to mount under the seat, which freed up trunk space nicely.

Violet U. ★★★★★

I play mostly electronic and hip-hop, and this little amp really wakes up the lows without taking up half the trunk. The 350w RMS rating feels honest and clean, and it stays cool even during longer drives.

Natalie ★★★★★

Installed this in my trunk yesterday and even though it's compact, it's pushing my 12" with real authority. The Class-D design keeps it cool even after an hour of loud listening, and the bass is tight without any distortion.
