To achieve the ultimate in-car music sound, you need dedicated power amplifiers. A 2-channel amplifier brings your front speakers to life. A 4-channel amplifier powers front and rear speakers, or front speakers and a dedicated subwoofer. For the ultimate set-up, use a 4-channel amplifier for front and rear speakers plus a separate mono amplifier for the subwoofer for tight, controlled bass and clear detail at every volume.
