2 18s Groundpounder 4th order

[Notoriousj76]

Ok, so I'm looking to get some really thick lows and need some experienced 4th order people to throw some opinions at me.

Astro Groundpounder that is my daily driver.

200 amp Excessive Amperage alt

4 C&D 75 ah batteries

Kinetic 2400 Racing front battery

Sundown Saz3000

2 Obsidian 18s

That's all you need to know about it.

I've been given advice from Hank (48 sundown 10s on youtube) to go with 6 cubes sealed 12 ported w/ removable port tuned 40-45.

Obviously 2:1 ratio.....

There is a guy I just found on youtube who was running a 4:1 ratio and tearing up the lows all the way down in the 15 hz range and I really like the way that was looking as far as air movement was concerning. He was running 3 18s (MA I believe) and 2 Sundown 3000s.

I am into cyclone bass and I'd like to sport Obsidian proudly by tuning really low, I just have limited knowledge about 4th orders. Opionions anyone? Sorry about making you read so much, and please keep the posts to informative things only. I don't wanna hear anything but relative information.

I'd go with what Hank mentioned. He knows a little about Astros. 3cubes per sub on the sealed side and 12 cubes on the ported side @ 40Hz will slam the lows. Not sure if it'd get down to 15Hz, but it more than likely would.

Ok... cool, It just seemed a bit.... cookie cutter sounding.
