well it depends- u can take the 15" and make it louder than the 4 12", but it will be alot of planing. Also u can take the 4 12" and make it louder than the 15". It would be better to go with a 15' i think because u will save money. Myself i have a 15" and it hits harder than people with 2 or 3 12". Its also mostly ur box. Give the 15" plenty of power and a big ported box.

The 4-12's will have more cone area. Given the fact that there won't be a huge power differential, I don't see how the 15 would be louder. As long as you are talking about giving the subs 600W each. If you are only giving them 150 W apiece, then they would be pretty close and in that case I would go with the 15, because you will save some trunk space.

if you have the money and the space, i'd go with the 12"s

Well the question wasn't for me to buy i already have a 15" i wanna know if my set up when done will be louder then this guy at my work i am competeing with i made my box to exact required size with a port and i am giving it the power its rated for rms. he just threw 4 12" in a sealed box that fits in his trunk and giving it 600W between the 4 of them . he has JDL pops i don't know anything about them and i have a audiobahn 1500x . So which would you bet on too win?

i would still say your 15" would beat him.
