Why isnt my system loud?

Im running a memphis pr 12d4v2 with a memphis mc1000d at 2 ohms so 600 watts and it does rated at 12v. My sub is in a long slot ported truck box about 49in long 5 in wide and 14.5 in tall.

Vehicle 1998 ford explorer sport

Type of amplifier you're running memphis 16-mc1000d

Whether or not you're running a factory head unit ,aftermarket pioneer

Box volume idk long truck ported

Box tuning unknown
just glancing at the specs, you are at 1 cube of it were sealed, you said it is ported, so you can deduct from there...and I am assuming 3/4" wood thickness. The sub calls for 1.5 optimum sealed and 2.35 optimum ported.

 
I have a memphis mc1000d at 2 ohms so about 600 watts running to one 12 memphis pr d4v2 in a long truck ported box.Why isnt my system loud if i have 600 watts playing.

OP- Please follow the advice everyone is putting in on the box (thats your weakest link). With a well tuned box and the correct airspace even entry level POS subs can sound good and get loud.

If your not up to designing/building the perfect enclosure there are a few guys in the enclosure forum that will design you a box tuned to your specific car/truck + there are lots of generic plans that will fit in back of alot of SUV's. I just had Mobile Enclosures hook me up with a sick box for 1/2 of what shops charge.

 
Just buy another PR 12 D4v2, get them in a good slot ported box with adequate port area and tune to mid 30's. Drop the impedance down to 1 ohm, then you will be doubling cone area, doubling power AND getting the gains from a ported box vs sealed....you could realistically expect at least 12+ db in output. Possibly more at the listening area depending on sub/port/box placement. Major gains in output, bro.
