Yea, it prob will be. It has a good box and quality subs ....

I just put a custom box with a pos 15 in it, in a jeep cherokee. I tuned it at 26hz also. Bass Labyrinth. 6 db gain at 30hz. And holy crap did it work insanely good in that JC... It (the jc) had the perfect res frq to make it play smooth and hard as fack ....

Only 850 rms and it will twitch your eyes ...lol ....

i don't know if it's going to behave the way you want. at 36" long, the 1/4 wave tuning frequency is 93Hz, but the free area isn't enough to be a traditional TL. it may behave like a ported box with a 5x11 port that is ~8" long (or however deep the outlet port is). how did you figure 26Hz tuning?

That's what I was thinking. A true t- line, the port is the entire length. 32hz would be over 8' long. 26 would be almost 11 ft of port length.

My box and port calc It hasn't failed me yet. But we'll see this weekend when I test and meter

software is only as good as building something that conforms to the assumptions made by the program designers. unless you draw the exact box in 3D and it figures the rest out. the issue is that you're trying to blend two boxes without doing either one correctly. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
