I've got a question!! I've got 4 audiobahn 12's (AW1200Q's) and a Mmats amp 600watts @4 ohms/2000watts @.5 ohms. I recently entered my first show and hit a 139.2 with 2 prefab boxes stacked on top of each other facing the back of my Expedition. My and was set with the gain all the way up and the internal crossover at 88 and today I was messing around and turned my boxes around and unstacked them and also turn the crossover up to around 155-165.
What kind of difference do it make when you turn the crossover up that high? It seemed to sound 2x louder and hit 2x harder.
And what kind of difference will a custom box make? from switching from a prefab box?
Thanks for your help.
