Compact four-channel amplifier

The Planet Audio MB300.4D is a new Mini Bang Series amplifier built for car-audio systems that need four channels of power in a small chassis. It delivers a maximum output of 1200 watts across all channels, making it suitable for driving component speakers or a pair of subwoofers in a space-constrained installation.

Replaces bulky multi-channel amps

Installers upgrading from larger four-channel units will appreciate the reduced footprint without sacrificing the 300.4 model designation and 1200-watt peak capability. The jump is worth it when rack space is limited but full-range power for front and rear speakers is still required.
