Two questions, is that port too, idk, curvy? Or will it work fine.

2nd: Whats the method to find the port length once I put those 45's in there?

Why are you tuning so low? Or is that one much higher than your last one

Is it bad to tune low? I mean, is there a point where tuning lower is pointless? I want to be able to hit the lows in Put On and stuff like that, I'm a big fan of the low-lows.

Then you've got the wrong sub imo. Realistically it should hit almost that low pretty well at 36hz. I'd try that first, and if you realy don't like it, maybe tune try lower then. Either way if you truly are looking for low-low's, which I would consider like mid-high 20's and below, you'll be able to hit them alot harder and with less effort with a sub made to do it than with a sub made to get loud and sound decent

Ok, so lets say I try to tune at 35, according to the CarStereo.com port size calculator my port area goes way up, what should I be using for Xmax? And is that at all related to Usable Throw? 'Cause from what I understand usable throw/2 = xmax? Or do I have it all wrong?

you're overcomplicating this

if you can get about 2.25 cubes @ 35hz with 36 or so sq in of port, you're good to go

Does 2.08cubes @ 35hz with (13x3) 36sq in of port (34.59 in of port length) sound good?

Edit: How does 2.24 cubes @ 35.5hz sound?

x2 that would be a good box to hit the lows with an HDC. How much power do you have?

Once I do my Big3 and get atleast a run of 4ga, around 1500wRms, lower until then.
