I was using one of the little RS speakers that was about 2"x2" and it sucked so bad I was questioning my whole CB rig.
I went to this:
Cobra® HighGear HG-S500 Noise-Canceling CB Spkr. w/ Talkback - RadioShack.com
And man, what a difference! It may also have something to do with the change from a lil wil to a 2700 but I'm pretty satisfied with it now.
I also have my speaker in the drivers footwell so that may have been why the little speaker didn't perform...
