??? Both of you all are WAY WAY OFF.

He said he has 2 ports 10x8sqin 9.6in long

He is tuned to just over 56hz!

That's WAY too high.

You will need to build a new box.

35.5in long PER PORT is required to achieve 35hz at that large of port area.

If slot ported, 31.5in PER PORT.

Where does it say he has two ports...? everything I bolded supports the fact that he has only one port that size...

Ok so i just got 1 re se 15's d2. I built my box to roughly 8.19 cubed after displacement. I thought i had it tuned to around 35 but it just doesnt sound right it only hits hard on the higher notes. Im assuming its tuned way to high. I allowed for 180 square inches of port? dont know if its right or not. my port is 10 x 8 and is 9.6 inches long. can someone please help me. Im dead tired and pissed cause it didnt turn out like i thought it would. BTW its in the back seat of my 4door car. subs are facing towards the front and the port is firing at the ceiling of the car. any help is appreciated.

I thought he meant subs too, but if he has two ports that big that would definitely be the problem...LOL

SOLVED-

He posted this in another forum, it's 2 subs.
