I went to get my truck tested and they take it out back to set it up. I'm walking around the store and a salesman comes up and says "They are testing it, wanna go see?" Of course i go see and talk to the guy testing it. So i tell him to turn it to 25, they do the test(in my friends prefab ported box it hit 135), and i leave. I put the sub back in my box and it just doesn't sound the same. Maybe it's just me, but it doesn't sound as loud or good as it used to. Did they f*ck up my ****? Because if they did i'm gonna snap on them.
