How to make the sub amplifier by easy way

How to make the sub amplifier by the easy way:

Today we are going to make a diagram for the control Tone to our amplifier. when we need the only bass to our amplifier. actually, I am going to making the sub without lowpass filter. there have many kinds of the amplifier circuit to our market but for the subwoofer is expensive. for this, we are going to make an easy way to off the tone from the sub amplifier. let’s go see that how to make the sub amplifier by easy way.

This is the diagram of this circuit.

we can see we use two volume for this preamplifier. those are 100 ohms. and we use only one 104j pf. we can use this preamplifier for any kinds of the amplifier. 

Let’s go to watch a video for making this type of sub-amplifier.
