How do you play Backtrack?
With computer and computer speaker? (like me )
Or do you run it with a big custom speaker?

I find it that I can't hear ANY of the backtrack if I run it through my computers speaker, is there a better way to play backtracks so I can hear over 30-50watt tube amps?

you can run it through your amp if you have a cd in
Carvin Bolt-T -> Line 6 DL-4 -> Danelectro Fish and Chips -> Homemade Fuzz -> Epiphone Valve Junior Combo -> Amplitube and Guitar Rig.
