Default 4th order SA-10's

Hey guys wanted to see if you guys can help me out. I really like the sounds of 4th orders and want to build one for my daily. Not a box designer so take it easy on me, max dem i have are 32WX16-18DX14H. Box is going into a GS300, using the stock 8" sub location for the port.

Let me know what you guys think of the box size and if it would work? Have no clue about the port or port size.

Going to be using a PPi 1800.1

I did a similar build with two XFL10s through the ski hole. Turned out very good and plays great. .4 sealed per sub and the rest ported. Tune it about 55hz and shrink the port as you desire.

Do just like you have in that picture, but place the baffle 3.5" to 4" away from the back wall. That should give you about 0.8 ft^3 of airspace for both subs and give you a sealed resonance around 48-50hz. Use a 6" round port 8"-9" in length, preferably with a few inches external through the rear opening so it doesn't get too close to the bottom of the enclosure on the inside terminus.

I should have around 4-5" from the box to the top of the rear deck. So your saying 4" to give me 0.8FT^3. Share airspace on the sealed side or not?
