Honestly though, youtube doesn't tell anything, at all, period. Not just the fact that it's recorded by video...but the fact that every vid you see is a different box, different amp, different wiring, different car, different source, etc. The only good comparison is between the same setup.
Like I said, the original Stroker is MUCH better than the new one. Not to bash the other guy selling the new one, but it is. Just do some research on google, you'll see what I mean!
