Amplifier is another essential part of a car audio system and it sure does have a long history. Our engineers innovatively built vacuum tube amplifiers for car audio when such kind of amp was widely used in home and pro audio. It puts out warm and smooth sound, perfect for vocal and instrument reproduction. With rigid die-cast aluminum heatsink enclosure, it became more durable and stable for car audio usage. Nowadays, MBQ's amplifier line covers from monoblock to multiple channels, Class AB and Class D as well, providing a wider range of choices for matching with different sound system upgrades.
