As the smallest amplifier in it's class in the world, the XR-400-4 mono amplifier - overcomes thermal radiation issues inherent to compact amplifiers and pack powerful Kenwood technology into a small form that enables installation in tight locations previously restricted to lower performance amps. This is ideal for users who do not wish to sacrifice boot space or prefer stealth installation.
