Hi, i just bought a 12" hdc3 and a powerbass xa3000 amp...i have an 04 avalanche and im looking to build a box into the factory midgate but am having problems finding the right way to port it. Im looking to build it round 30" wide, 15" high" and 13" deep so i still have room to fold the midgate down...that is roughly 2.5 cubic ft before displacement....i am wanting to tune it to round 36 hz or so being that i read that 38 is best for that sub.
Right now it is in a prefab box which is only 1.5 cubic ft and supposed to be tuned to 40hz yet it wont pick those signals up for some reason but hits lows hard!?
So what i am wondering is do you think that would be a good size? And if so what size should the port be? im gonna be doing a slot port so wondering how wide it should be and how far back it should go. Thanks for any help guys!
