Port info for 6.5" subs.

[SilverSquared 10+ year member]

I have a dual chamber sealed box, I've decided to go ahead and port it to get as much as I can out of my little subs. I have American Bass XD-65s. My enclosure is 0.95 cu ft per chamber. Is this too large? Here's the details on the subs below. I am thinking of going with a 3" diameter aero in each chamber, I just need to know the length. Thanks ahead of time!

Probably looking around 20 inches or so, with flares 24 to 26 inches. Is that doable in the enclosure?

3" diameter is fine, might need to have it sticking out if the enclosure is not long enough.

I built a tline for mine and it gets down in the wife's Sequoia. Digs low too lol. Loudest single 6.5 set up I've ever done.

Id LOVE to build a transmission for mine. I had a pair of kicker impulse 12s in a tline that took up the ENTIRE ext cab of my B2200. But WOW. VERY loud.

What I am doing is for a 2005 extended cab silverado. I have a sealed downfire box for 2-12s under the seat now. What I will do is put the 6.5s in, and port it.

I'm most likely going to aeroport and basically from the front, and 90° to get more length, as the box is just at 15" front to back.
