3 10's vs 2 12's?

[ShoreThing]

I recently purchased a $1300 subwoofer setup from my friends shop to be installed in my 06 F-350 Lariat crew cab long bed. while writing me up for 2 12's they didnt realize that i had a motorized back window which happens to take up a bit of space that they planned on using. The subs i purchased were the higher end series of Phoenix Gold 12'' shallow mounts to go behind the back seats. About an hour in my buddy came out to the show room and told me that there was no way they could fit 12's behind the seats. He upsold me to 3 Phoenix Gold 10's and a larger amp (got the friend discount and it was only $300 more). i was excited at first but over the past few days ive been told that the 3 10's wont sound nearly as well as the two 12's... I'm new to the game and dont have enough knowledge to know one from the other. therefore i am reaching out to you all for your honest opinion. Am i getting a better system or not? he set me up with a single 12 in an enclosed box just to roll around with but the custom box will be installed friday. lets hear your honest opinions!

Those look decent. As long as the build is built correctly that should bang pretty good.

The 10's will have more surface area 235.5 sq.in compared to the 226 of the 12's. Not enough to notice. I bet those 10's sound pretty damned good. I wouldn't let the hearsay scare you.

thanks for your input. my guy owns his shop and is the best around in the area, i just wanted to make sure i was still getting that 'BOOM BOOM POW" haha.

end result, am i losing, gaining or breaking even?

You're breaking about even IMO. In that application i dont think you could tell the difference in the small amount of cone area. You get the bonus of saying you have three 10's though.
