I agree with Bafukie.
If ppl are expected to search the forum and read all 10001 post, then might as well just google and skip this sub forum.
Ppl should be allowed to post and ask for help/reco specific to their system or environment.
Although 1 thread per person should be the limit.

I think your basstube is the problem. The amp should be more than enough. Your gains are also probably incorrectly set. i have an old rf 12" in a box if you wanna see if the amp is ok or not. that rf can be heard a block away even on a 2X75W lightning audio amp.
