[QUOTE="Jeffdachef, post: 8645273, member: 650438"] Get any kind of home theater logic out of car audio completely and never ever link the two together again. Home audio you dont deal with cancellation and rear waves anywhere as close to what happens in a car environment. Home theater is literally EZ sound for dummies vs Car audio which has a lot more acoustical challenges going on in it. Whatever you think is good is basically complete garbage in actual real world results purely due to cancellation aka ZERO bass. The only way any of this would even work would be to go down to two 10s and do a 4th order blow through. Your first idea of porting 15s with already a tiny sealed box is already beyond stupid because ported literally needs a box 2-3 times the size of your sealed to even properly perform. I'd highly recommend reading up on ALLLL the basics of car audio enclosures before screwing up your system even more. A proper ported box for two 15s would be around 7 cubic feet to 9 cubic feet NET meaning subtracting all the space the wood, bracing, subwoofer and port takes up. thats pure 7-9 cubic feet of airspace alone just for the sub to properly function and breathe. Your port needs to be big enough as well. for two 15s, you need at least a 6-8 inch aeroport. So yeah man, just leave sh*t as is. Or actually sell everything and do things right because all you are doing is shoving things that dont work in a small space like a big noob.
