Early 90's Precision Power (PPI) ProMOS 50 Review and Amp Dyno Test [4K]

#OldSchoolStereo #CarAudio #PPI
Today we are taking a closer look at a classic 90's "cheater" amp, the Precision Power ProMOS 50. This is a high current, low impedance class AB amp from the early days of cheater amps. It's rated to deliver:

50x2 at 4 ohms
100x2 at 2 ohms (or 200x1 bridged at 4)
200x2 at 1 ohm (or 400x1 bridged at 2)

Amp was made between 1990-1995, the version I have appears to be manufactured in 1994. No crossovers, no bass boosts, no frills...just plan amplification
