XFL 1522 Box help needed!

[Bigwheelw]

I have a AB XFL 1522 and an execution audio 1000.1 amp I drive a Mercury Grand Marquis so I have a good amount of trunk space. I'm relatively new to the"sport" but I shouldn't have any trouble building the box.

So what's your question?

[Bigwheelw]

My question is can someone give me box build specs?

[Michael Runninger]

What year is your Mercury. I am currently building boxes for my crown Vic. They will fit in the side behind the taillight. They should be about the same. I can give you what I have so far. I WO LD get cardboard or poster board and make the box out of that first so you have templates and then build the box.

It's a 98

I looked at some photos on Google and found some nice box setups that would work for you without loosing to much trunk space. There is a big difference between the to cars so I would need to a look at the trunk in order to get dimensions.

[Bigwheelw]

I'm not too worried about losing trunk space. I'm just wondering if you could go to big for this sub and what port sizing to use. I can send you pics or dimensions of the trunk. I really appreciate the help.

So here is a suggestion, power: to sub rated, amp subsonic filter to 28Hz, minimum port clearance 3 1/2", figure is just an assembly guide:

NOTE: If building outside you need to build a cardboard dummy box to test fit in it's way inside.

[Bigwheelw]

So a bigger box isn't better then. I have always been told install the biggest box you can fit.

[Joe X]

Well that may be true but in a different way, for example you could build a larger box for multiple drivers or a larger box for a larger driver BUT you can not build a box as big as you want for a single driver without consequence, with enough power a driver in a box too big for it will bottom out and eventually fail mechanically, even if you keep the power low it will get loud only around the box tuning (speaking of a ported box) so it will sound pretty bad, a larger box is generally a good idea but to a limit.
