Entered my first Meca comp and need pointers

50hz is your resonant frequency in that vehicle. Atleast with our testing. Blazer will get loud. We have done a 150 with 2 15's and less then 2000watts. I'd recommend subs side port back. That was loudest

This is new to me so dont laugh but do u mean subs towards the side windows and port towrds the rear hatch??
