jl 12w7 subwoofer w7

Hi, my name is Tanner (or Tan Tan), im not a pro by any means, but I like my car audio, and audio in general. So, I bought this sub off a buddy, a JL 12W7AE3, built the box, powered it with a 1000 watt JL amp. sounds amazing, no complaints. Worked good for a couple years, then one day I went to...

I toyed with the famous JL w7 12" The box specs was just under 4cu.ft tuned to 26hz Hits pretty low and of course clean. Not as loud as expected tho.
