I just bought a bassworx dual 12 inch ported box, my put my 2 alpine subs in it. i am powering them with a power acoustiks 2 channel 300 rms x 2. i am gettin that god awful farting noise, i was wondering if anyone had a solution. if it makes a difference the subs are faced towards my seats and not to the trunk latch. The ports are also facing up.

 

I had that once and it was the tuning ... Back wen i thaught a hole in the box was a port anyways

 

so thats all it is just the tuning? the box isnt too big or the direction the subs are facing?
