my father just bought a bunch of rockford fosgate subs so today we decided to test a few of them out. well first we tried out a 10 p2, and we were little speechless how one sub could be so clean and loud. then we got adventrous and tried a 10 p3. all i can say after that experience is p3 ftw!!! one kid who was there also noted that it was louder than his two 12" xplodes

 

xplods suck lol.. but i've never heard rockford i know a few people with them though, but i'd bet my 10's would beat it.

 

i don't have experience with the sony xplods but of all the subs, they look pretty damn nice

 

the subs always depend on the encloser!
most people dont realize that...
ported boxes... always louder than sealed boxes and box size also makes a difference.. as well as firing direction...
and even more most the time is the amplifier.

 

ya the box we had for the tens was 1.25 cubic feet and slot ported. my dad had the backseat down with the sub firing into the car b/c he thought it would be louder. we turned the sub around so it was firing to the rear and flipped the seat up and it was alot louder. alot more clarity aswell.
