Can somebody explain what all this doo an how can I connect my car radio to this Amp and to a subwoofer?

  1. Everything would be more simple if you could give us the Amps model and manufacturer information.
    -This also enables the search for the user manual. That informs and explains what everything does.
  2. It would help to know what system (all of them) headunit, speakers etc you have in the car and what are you wanting to do?

But from nothing that is a 4-channel amplifier and you can connect headunit outputs to amplifiers inputs to 1/2 input or 3/4 input, depending of number 2 question above. For what is the end goal.
The rest of settings are Crossover, Low-Pass filter, High-pass filter, Bass EQ, Gain for 3/4 channels.
Mentioned inputs and even Output for another amplifier. Then again same settings for 1/2 channels.
