About: CT Sounds M-75.4AB 4-Channel Car Audio Amplifier - 105W RMS x 4 

Looking to go incognito? The CT Sounds M-75.4AB Limited Red Edition 4-Channel Car Audio Amplifier is proof it's not the size that matters, you get the power you want and save the space you need with this amplifier. Pumping out 420w RMS in a package small enough to fit just about anywhere. Pair this with the M-750.1D and you will be set for a full range of clean power without giving up the space needed for larger amplifiers.

The 4ch car amplifier is built with a MOSFET power supply, high-quality capacitors, advanced transformers, and cutting-edge inductors allowing for maximum current flow and power output making this amplifier extremely efficient. Furthermore, it is equipped with Korean capacitors which provide the amplifier with the ability to store more capacity and cover the capacity difference in applications where the amplifier draws more current than is available from the electrical system

Pure Class-AB amplifier, which ensures greater efficiency through both Class A’s & Class B’s individual operational productivity along with lower distortion.
