CT Sounds brings you an amplifier that precisely is small in dimensions; yet  powerful in audio amplification. Introducing the M-75.4 car audio amplifier. This is a 4-channel amplifier that solely operates on Class-AB audio amplification. This comes to you with the capability of amplifying audio in 3 different load ratings at 3 different power outputs. This amplifier is just ideal when you are looking for compact audio system in your vehicle with a moderate power ratings around.


  1. It has bridgeable outputs
  2. TRI mode capable (for 3 speakers)
  3. MOSFET PWM (Pulse Width Modulated) power supply
  4. Soft turn on circuitry
  5. Thermal, DC offset, overload and speaker short protection inbuilt
  6. Nickel plated RCAs, thus low resistance inputs to the amp
  7. LED power and protection indicators
  8. This is a purely Class-AB amplifier, which ensures greater efficiency through both- Class A’s & Class B’s individual operational productivity along with lower distortion
