I myself believe in 12 12" Funkypups powered by two JL 1000/1's Make sure the pups are 8ohm. And then put them in a 5th order bandpass. Then make sure you have one sheet of dynamat on the trunk lid. finally, since they are slash series, use at least 4 g power and it is ok to use 12g ground. after all, it is only ground wire, not like current is going through it. BTW, it is fine if you run the power, ground and rca's together in the same split loom.
