Need help Designing Box for HDC3 18's

[genocide747]

Hey so I just got two AudioQue 18's and I currently am going to be running 3000-3500 watts to them daily. I want to be as loud as possible so I need a little help with the box. I need to know idea's for the size, deminsions, and port size and tuning. This is my third box but I thought I'd get a little input to help make this one the best it can possibly be. Thank you

do about 12 cubes after all displacements, with tuning around 37hz....3 8" aero's should be plenty port area.

8" aeros will help with that.

What vehicle?

How much room do you have and electrical. What amp?

Hopefully someone with actual hdc 18 expirience will chime in. I Know the 15's sound great in the reccomended enclosure size of 4.5 feet, single 8" aero and 35hz tuning. So if they say 6ft go with that. But if you only have 1700 a piece for them Id go 10% larger. like 6.75 ft per.

I'd do 12net 36-40hz depending on what music you like to listen to. 36 if you listen to a bunch of chopped & screwed crap. I prefer to use 38hz...

2 completely difrent vehicles dude

Ive got 2 HDC3 18's on 3500 in an suv, exact box as listed first, 12 cubes after displacement, 3 8" aero's, tuned @ 32 and 40hz (plug a port for 32 hz) and its crazy loud

Slams the shit outta me, and my amps not even running full bore because Im lacking electrical hard dipping low 11's.

Mines a wall though
