How to drive a subwoofer with my amp?

[evcil]

Hello everyone, I have a basic LM1875 amplifier made with a basic PCB from AliExpress. I am really not getting any bass from the speakers, but the speakers I use are satellite Logitech speakers. Is the reason for no bass is that I only have treble speakers? If so, can I hear some more when I connect a fullrange speaker? Or is my amplifier just not enough? I have the PCB linked below, and keep in mind that I am not a basshead, but I really do not hear anything below 250hz from these speakers. Thanks!

You can not expect to get bass from the satellite speakers which were designed to be used with the separate woofer.

You should get adequate bass if you use small bookshelf speakers instead.

Perhaps you could borrow a pair from a friend to make sure.
