zv4 tuning question

[turnt up 0]

Hello all, I'm in the process of designing a box for my 99 grand Marquis.

One zv4 15 d1 running of a bc3500 @2 ohm for now, until I get a new alternator soon, then will do.5 ohm.

The two options I have with the space available would be 3.5 cubes net with 60"port volume and 36.5"length. This would give me ~32 hertz...I think.

Or 3.75 cubes net with 38.5" port length to give me ~30 hertz.

So my question is, if I go with the bigger box with the lower tuning, will I lose allot of output in the top end?

The sub will be firing up with the port firing back.

I also cut out behind the arm rest and took the speakers out rear deck to let more air flow Through

Why is that the only 2 you can do?

Well this was what I came up with so far and I'm just learning. if I go bigger I need more port area, and length and it just gets too big. I want to have access to the amps which are mounted up on the hump
