I have a DC XL m1 18 that i am wanting to put in my truck (02 Silverado 1500HD). I am thinking about taking the 60 part of my 60/40 back seat and making a box above my amp rack. I am wanting to tune to 30 hz or lower and would like to possibly do a hairtrick. Is it possible to do in my truck with a single 18?

Here is what I have right now:

1 DC XL m1 18 D2

1 Crescendo BC2000D

1 Mechman 270 amp alternator

1 Stinger SPP1500D battery under the hood

All 1/0 for big 3 and running to amp

This is a box I come up with

Would I need more port? Should I change anything else? And where should I place the port? the sub will either be facing up or forward. Should the port face forward, up, or in some other direction?

I would do sub forward and port up. I would also not worry about doing a hairtrick. It either will do one or it wont. I have seen setups that hairtrick like a boss and sound like complete ass.

^^^ he's right.

you might be able to do it, you might not. there is only one way to find out.

but don't expect crazy hairtricks!

Oh i dont expect anything crazy. I just want something to say i did one pretty much. I wanna move some air

go for it, its the only way you'll ever find out if it is possible.

good luck and show us the results.
