Hello everyone, ok Im planning on ordering 4 Q15s for my pt cruiser, it will be a single sealed box with 2 subs facing up and 2 subs facing foward, how does this setup sound? Will it effect sound quality or overall output, also there be 2 seperate chambers with 2 subs in each chamber, or should I go for 1 chamber for each sub? thanks..........Brian
