that box is too small. 3.8cf NET is WAY too small for an 18" sub. I'd say at least 5.5-7cf for those, each, NET. especially when tuned that low.

Did you ever think to try 1 18" I know someone that pulls a 155+ with a single 18"... If the box has the internal volume and the port area you will get the numbers on the Mic.
