ok guys im sitting here making the final designs to the blazers street box. now i have a box that is 4.53^3 and i want to tune it to 48hz the resonant frequency of the blazer is 48. now i cant decide if i want 4 or 5 ports. there going to be 4in dia. aero ports. and i cant decide if i want to fire the sub up or back and the ports also up or back. lemme know!

fire the sub back

pure spl? id fire it all forward.....

i dont want to fire it forward back and up are my only options. its against meca street rules

its against meca street rules

to fire your sub forward?

In an SUV? What about the rear seats?

To tell you the truth Bill I think your best bet will be sub/ports on the same plane. Sub pushed off to the drivers side..ports on the passenger side. I dont see much benifit in running I suppose you can do 5, but I think 4 will do the trick honestly.

I agree sounds like that will give you the best bang for your buck

u want the port on the opposite side of the meter. in meca its measured in the kick so im doing opposite of what you suggested i think

In an SUV? What about the rear seats?

oh i forgot....i have never been in an suv....just kidding of course i have been in an suv.....but certainly if we are talking about a vehicle for pure spl there are going to be some compromises and since bill has an audio business i think he will be forced into a higher class where more modifications are allowed(and forgive me for not memorizing the rule book, its on file at work but i dont have it at home)

i c what you mean smoker lol and becasue i have a buisness it only means i cannot compete in the amature classes i can compete in street however and thats what i plan on doing. s3-s4 and firing forward is illgegal in that class.
