Ampire's best-selling monoblock amplifier is the MBM500.1, which delivers an impressive 500 W RMS of power in an exceptionally compact housing. Measuring just 251 x 141 x 50 mm, the unit features a comprehensive active crossover, a subsonic filter to protect the subwoofer, adjustable bass boost, and both RCA and speaker-level inputs (the latter with an auto-turn-on function). It is no surprise that this amplifier was named the test winner in issue 4/12 of *Car & Hifi* magazine. MBM500.1
