hello i had the help of this site for my solo X 12 last year and now im here again asking for help with my 4 12" rockford fosgate subs. they are the old school power HE2 subs.

a seal box of 4 12" connect together is the maximum size width i can go.but i can go a bit higher and a bit deeper.

i want to put all 4 12" in a port box. i do not understand calculation but pictures or measurement is very helpful. this will be going in a chevy impala ss

Power HE2? No such thing...maybe you meant Power HX2 or Punch HE2?

okay since i didnt get any reply i went out with a ruler and the biggest i could go without getting technical would be 66w X 18 L x 18 H . this is for an impala ss 96. this also will be a tight fit. i cant port it forward because the sub is pretty close to the back of the car so either port UP or port back. help?

here is the box i want. but do not want to fork over 300 dollars for it at the moment. im actually good at building box so i rather do it anyways.

Probox 4-12" Turbo Bass enclosure with bedliner coated.

Each chamber are separate and ported. This box produces extreme loud bass.

Air space (each section): 2.05 cu. ft.

Dimension: 52-1/2" W x 15-1/2" H x 22" D

Weight: 110 lbs.

this box would fit in my car but the port would be MUFFED. and the size 22" would not fit unless i was to notch my frame inside the trunk a bit.


this is my set up now. it's extremely loud but sometimes i battle with other. a port box like the one shown above is an automatically WIN.

so keep in mind the port on the probox turbo bass is going to be pretty close to the car bumper. maybe i should turn the box around ??
