this may be a really silly question
but I am new to this ICE stuff.
I have a sub out and a sub control on my head unit so do I still need a seperate amp to run a bass tube or can I just plug it directly into the head unit?
If I do have to use an amp, is it best to use the pre-out or the sub-out to run the bass tube? (I would prefer a sub box but I have been given a bass tube and figured it would be a good starting point).
