How to drive a subwoofer with my amp?

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!
