There's no way you can fit (2) 12's ported in a sonoma without a blow through. I'd suggest you sell them and use the money to beef up the electrical and buy the beefiest 10'' you can find and a big amp. A 10'' in a well built box will get much louder than a 12'' in a box that is choking it.I have two Mach 5 SPL-12s....
