Hey guy's, I am new to the forums and to Sundown Audio. I have just received 3 SA8 V2's that I will be running @ 1.3 Ohms powered by a RF T1500-1BDCP (hopefully enough power). My dilemma is I drive a 93 Chevy Silverado Single cab so my options for an enclosure are limited. It will be an angled box with the subs firing down (braced 3" off the ground) and the port facing the passenger side wall. My question is..... Do the numbers below add up? I am getting conflicting calculations from different programs i.e. different cubic feet sizes, port sizes etc..etc.. So if anyone can confirm the below numbers your help is greatly appreciated.
