Series tune 6th order for sundown x12v2

[coach k]

Been following all of the avid 6th order connesiers for about 3 months and I decided to start with a small build on my work truck.sundown x12 series tuned 6th order on roughly 1200-2k watts.I've been modeling taking in strong consideration the findings of a 6th order port area experiment a member did but I wanted to compare my specs with other more experience members.Rear chamber:2.5cubes@28hz/35insq of port.Front chamber:7cubes@56/111insq of port.Again these specs were designed around the findings of the experiment Mr T.A. conducted as I wanted a wider bandwidth.Thank you fellas in advance.By the way I forgot it's a blowthrough so I'm going to need about 4-5 inch long front port for clearance from the bed to the cabin.
