Especially suitable for car HiFi applications but also an excellent addition to home cinema systems and home HiFi systems as well as multimedia applications like PC games. Easy mounting due to screwing to the lower side or rear side of the seat. Connection to a suitable power amplifier via basic passive crossover network as for subwoofers, or even better via an individual amplifier.
