  • The Skar Audio SK-M4004D full range class D four channel amplifier is part of the new mini amplifier series product lineup from Skar Audio. The SK-M4004D was engineered to be compact, but provide the power and reliability expected out of larger amplifiers. Featuring a high speed MOSFET power supply, and an efficient Class D design, this amplifier is powerful, reliable, and extremely versatile.

    The SK-M4004D makes for a great amplifier in applications where space is limited but power cannot be sacrificed. In addition, this four channel amplifier features high level input connections for those installations that lack an RCA connection. In addition to the high level inputs, this amplifier also utilizes an adapter harness for the speaker outputs allowing for an easier installation.

Which one is it?

Just received 5/12/2021 and was reading owner's manual. The manual states:

Power @ 4 ohms 80w x 4
Power @ 2 ohms 134 x 4

Not the 100 watts rms @ 4ohms x 4 and 140 watts at 2 ohms x 4
So which one is it?
