Here is a cross post, It hits lows well but everything else sounds like junk. I had Boomsday build the box like everyone told me 35hrtz 5^ft was a epic pain in the *** to install and would much rather have bought a premade. So no i'm thinking about shoving a blanket in the port to get some tighter bass.... so i spent 190 on subs 200 on amp 135 on box and 70 on wiring and i hate my system would much rather bought used type r's off craigslist and nothing i can do now...
