20 cm (8") Active Subwoofer System for spare wheel/rim bed (from 15 inch)


A popular option is to install it in an existing spare wheel or spare wheel well. Hereby no valuable space in the trunk is wasted. With a height of just 10 cm, the CRUNCH GP820 system even fits in many spare wheels. With an outer diameter of just 34 cm, this is actually one of the most compact subwoofer systems of this type. The built-in 150 Watts RMS Class A/B amplifier powerfully drives the 50 mm voice coil of the powerful 20 cm (8") subwoofer. The installation is very easy. Simply attach the included mounting plate with the spare wheel's original screw and screw the GP820 into the holder - done. The scope of delivery includes a remote control with which you can not only control the bass level from the driver's seat, but also the crossover frequency and phase.
