They are pretty good with the power they are getting now, i imagine they are getting around 150 the way they are wired up. They get pretty loud, they way they are right now....If you want them, You can have them for $90, you pay the extra shipping...PM me if you want them....but I like them, I am just getting 2 12's because of the price they were. The kickers are in a sealed box, They get pretty loud the way they are, but It would be alot louder with the 300rms they are rated at....
