Looks like I am going to do a small blow through to be able to fit this hdc4-12 in my extra cab GMC, most likely going to have a DD M3B for power, so it'll be getting all the power it wants.
How many cubes and recommended tuning would ya'll suggest?
I was thinking about 2.25 cu. ft. with a single 6" aero tuned around 35, sound about right?
If anybody has a proven design for one would be a plus.
