Anyone wanting to enjoy invisible bass in their vehicle opts for so-called active under-seat subwoofers. However, if there’s no space under the seats, the only alternative installation option is in the trunk. For space reasons, a spare tire well is often considered. If the spare tire diameter is very small, however, only very compact models like the MERCURY MRX200A can be used. With a diameter of just 25 cm and a height of only 8 cm, it’s ideal for this purpose and fits in rims as small as 12 inches in diameter. Fans of classic cars with small spare tires will especially appreciate the MRX system. It’s astonishing how much bass pressure comes from such a small enclosure.

To ensure that the compact MRX200A bass wonder also consumes very little power, it features a highly efficient Class D amplifier with an efficiency of up to 87%. The advantage here, compared to conventional Class A/B amplifiers, is the minimal heat generation, as very little energy loss needs to be converted into heat. With a true 125 watts RMS output, it’s very powerful. The aluminum cone it drives perfectly converts this power into sound pressure. The result is a tight and powerful bass.
