I just got two polk 12's with the pre-fab box this weekend for a good deal. I'll post pictures up soon.

 

I have two 15" Kicker CVR's with a 2400 watt D class Power Akoustic amp. I work at a stereo shop so its not really fair when it comes to bass comps. But on the SLP DB meter I hit 145.0 DB's. People place the meter in different places within the car but I always put mine on the passenger side of the front windshield.

 

i got 2 12"s of the old style jlw6's and i love them. Great sound quality and good spl. I want to put mine in ported boxes. It sounds good sealed but i just prefer ported. I wish i had more of them. haha. got them wired down into 1 ohm.

 

I had one of my co workers cousin go in to our work today for some parts and he was bumping music and it sounded alright so I asked my co worker ask your cousin what's he got so he said oh he has some bad 2 kicker 15" cvrs so I was let's take a look and so he was raising the volume and I was like that's good and he said what do you have or you don't have one so I was yeah just one FI BTL !5" and he said joking around bet its not loud like 2 15" speaking of his so I told him do you want me to play music or songs that are for spl and he said music DANM!!!!!! When I lowered my volume I've never heared a 1 15" being that loud and with clean bass so then I let him have it and I was playing 40hz tones and 20hz to 60hz and he didn't even bump when he left just left with his part saying danm that was loud haha but props to everyone out there with some BUMP.
