When something is called "Primo" it has to be the best! So Massive Audio released "Primo Series" amplifiers.

Every Primo amp is "under rated" on power. All models are pretested and will outperform their published CTA 2006 rating. I.C.P. (In Car Performance) is the main design goal. 

The PRIMO car audio amplifiers are the best for audiophiles behind a wheel! All 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 of course more than CTA2006 Compliant. All models feature Built-in OEM Line Converters @ up to 10 Volts input with ATO (Auto Turn On / with no turn on wire needed) and 12 volt output so you can power other applicable 12 volt electronics. 

The P4 amplifiers come in a 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!
