A subwoofer system is more than just a great speaker. Great bass requires an amplifier, an enclosure and a speaker to work together as a system. Because all the components in BassLink were designed to go together, each component was optimized for its particular job. The result is great bass in a cool-looking, space-saving package.Thanks to the Class D amplification included in BassLink, more of the power the amplifier extracts from the car’s charging system is converted into output to the speaker, and less is wasted as heat. That’s a big deal in today’s cars, which include all kinds of powered accessories.
