The AWAVE AST-10T is an active subwoofer designed to fit discreetly into the spare wheel niche of your vehicle, allowing you to add deep bass without sacrificing luggage space. It features a 10-inch driver powered by a Class D amplifier that delivers 200 W RMS, providing a substantial low-end response for your music. To ensure the sound blends well with your other speakers, you can adjust the phase between 0 and 180 degrees and set the low-pass filter anywhere from 50 to 200 Hz. Installation is straightforward thanks to high-level inputs with an auto turn-on feature, though RCA inputs are also available for more traditional setups. You can fine-tune the audio experience using the gain and bass boost controls, while the included wired remote controller lets you make adjustments on the fly from the driver's seat. With a diameter of 360 mm and a height of 120 mm, this unit is compatible with spare wheel wells starting from 15 inches, making it a practical choice for drivers who want a powerful audio upgrade that stays hidden from view.
