I've never made a fart box before and I want to whip one up by the end of the month for a comp. Anyone have any suggestion for and 18" BTL? Power is coming from an IA 20.1 @ 1 ohm (underpowered I know) and 2 G31 Optimas. I peaked at 43 HZ last time I metered but I was tuned to 32 HZ with a DD 3515. Vehicle is a 2003 Nissan XTerra. so I guess I would like input on..
1. how many cubes
2. port area
3.tuning
4.sub/ port placement

Thanks!!

no chance of getting another 20.1 and strapping them?

Thats the plan eventually... I'm having a hell of a time finding someone with a 20.1 that will take paypal....

just build a box with external aero's, that way you can use it for daily while traveling there then switch out the aero for a fart box

4-5 cubes
2 6" Aeros external
40hz?

Since hes underpowering it, it wouldn't hurt to go a tad bigger.

hmmm... I always wondered why people did external aeros.... it so obvious now:laugh: That'd be super easy to swap... 6" aeros aren't cheap though:crap:

6 cubes, external aeros, change up as you need for daily and comps, easy enough.

they also help with smooth flow on the inside of the box, no ports messing with the air flow on the inside

and easy to change tuning

Thanks for the help guys... I think I have a pretty good idea what I'm gonna do.

If you have a sealed sub setup you could run it and play a sweep in your car to figure out where your car peaks at and then tune your box close to that to maximize your port tuning.
