^This! I am running a 150 Watt Rockford Fosgate P1 in a Rockford Fosgate P1 "Custom ported box" or w/e and it is crisp and can be decently loud. (Not the blow your eardrums loud tho cuz that isn't my style)It will sound much better if the back of the sub box is against the back of the rear seat. Only amateurs face it toward the passenger compartment.
One 10 in a well built ported custom box is just as loud as two 12's in a store bought box and the 10 is much tighter too. In the last place I worked we had a display setup to prove it.
By well built I mean that the port volume is calculated to the sub specs, the box is reasonably thick, glued together, with fiberglass resin on the inside of the joints and the plug for the wires.
Amen to that...my 10" alpine is in a custom box facing the rear of the car and depending on what i am listening to and how loud the sw level is...can be deafening.. most the time i keep it low (5 on a 15 scale)It will sound much better if the back of the sub box is against the back of the rear seat. Only amateurs face it toward the passenger compartment.
