Question Upgrading GX AMP

[jbrewer193]

I currently have an older GX Sound system with 2 speakers and a subwoofer. Recently my cone for my sub tore and I happened to come across another sub but it is a higher wattage. I can control the bass to make it not as loud and not cut out but does anyone know if there is any other PC AMP volume control device that has Volume RCA Input and Output with a Bass Output too? I'm looking for at least 90 Watts total

Attached is a picture of the amp that I am looking to replace.

Thank you!

Could you be a bit more specific with the SKU to your Genius speaker set? What is the impedance of the speakers and what is your max impedance for the amp?

Recently my cone for my sub tore
Why not just try and replace the cone?
