Thread: volume control questions

So I have built my car stereo... now I want to take the knowledge that I learned there and put it to use in other ways. I have decided to build myself a nice desk, complete with built in speakers and subs. Here is what I am picturing. Audio cable running from computer to volume knob to control overall volume then from that knob run to 4 channel amp, 2 channels for left and right speakers two channels for sub. run speaker wire from amp to speakers, run speaker wire from amp to another volume knob to control the bass level and then to the sub. Would this work? I really don't know anything about how these things work, I just know how to wire them to work in the car. Would this set up do what I want, be able to control overall volume and bass levels? I am looking to build my own knobs, just to increase the learning experience. Would these be anything more than just getting two dual gang pots (terms that I learned about moments ago from google)? Any advice or links or dope slaps would be appreciated. Thanks!
