PX1900.4 - 150 Watts RMS x 4 @ 4 Ohm 4 Channel Amplifier

When something is called "Primo" it has to be the best! So Massive Audio released "Primo Series" amplifiers. Simply the best for audiophiles behind a wheel!

All 5 PRIMO amps use Mil Spec PCBs, SMD parts, 5 way protection, full MOSFET high grade switching devices and comply with the “World Wide Standards”, “ROHS”, “E-Mark” and are CTA2006 Compliant. All models feature Built In OEM Line Converters @ up to 9V In with ATO (Auto Turn On / no turn on wire needed) and 12V out. The 4 channel PX1200.4 & PX1900.4 and 3 Mono P1200.1, P2000.1 & P3200.1 come in polished aluminum fin less heat sink with a blue back lit logo. Only top quality 1% resistors, caps, connectors complete the "no compromise design".

Each model supports a "Docking Port" to plug in an optional custom matching 4 Farad Railcap Booster (RCX).  Want the best? Go Primo!
