Massive Audio 600 Watts RMS 4 Ohm 4-Channel Class D Amplifier – PX4S
This Listing Includes:
- (1) Massive Audio 600 Watts RMS 4 Ohm 4-Channel Class D Amplifier – PX4S
According to Merriam Websters Dictionary, primo is considered to be Of The Finest Quality. Living up to that standard we proudly present another entry in the Massive Audio PRIMO series of Class D Amplifiers, designed and engineered in the USA. This PRIMO PX4S is a multi-channel Amplifier that easily delivers up to 240 Watts RMS to each of @2 ohm and 480 Watts @4 ohm in a small footprint. All PRIMO series amps use Mil Spec PCBs with Surface Mount Devices.
