I wanted to go for a "stealthy look". The sub and amp will be facing the back seat in my blazer. The smaller picture of the box is the view of the box if you were looking in from the back window. I am going with the factory specifications. The box is .75 CU feet and will be tuned to 28 hz. Do you guys think I will be disapointed with the soundquality having the sub face the back seat? I want it hidden because I don't want to scratch or get any of the equipment dirty with my mountainboard gear. Let me know what you think.

Jeese, I am going to have ta bump this up . Plus I have been on another board and they said that the box won't be tuned to 28 hz. The port will be 25" long and 3" diameter (.75 cu feet). Does anyone agree with those dudes?

Personally I think your date there in your avatar is hott. me-ow..

As for the vent: 0.75 cuft @ 28hz tune with a 3" diameter vent = 30" long. At 25" long it will be tuned 30-31hz. Do whatever fits, you won't hear the difference.

Be careful what you wish for...

Hahaha, yes she is very beautiful and she has a kick ass personality, Thanks Dukk (I spelled your name right this time ).

And I started found a calculator right after I posted this and found out that, like you said, a 30" port will get me 28hz. So here are the specs for it:

BOX
-tuned to 28hz
-1518 cubic inches (.88 cubic feet) total
-minus the port and subwoofer, plus the 1.5 inch thick baffle space equals .75 cubic feet

PORT
-3 inch diameter
-30 inches long

DIMENSIONS (air space)
20.5" wide
7" deep
10.5" tall

I am hoping everything is right. If you guys see anything wrong with it let me know .
