The amazingly small XD amplifiers are huge in audio performance, thanks to our advanced NexD™ switching technologies.

These technologies allow XD amplifiers to achieve efficiencies exceeding 80%, meaning far less heat and strain on your vehicle's electrical system than a conventional large amplifier would generate. This efficiency advantage, combined with state-of-the-art microelectronic components, allows us to use very compact unitary cast alloy heat sinks. Just like their more expensive HD siblings, XD's deploy our Advanced Thermal Rollback System to completely eliminate annoying thermal shut-down events. The end result is outstanding audio performance and reliability in a compact amplifier that is easy to install in the tightest spaces.
