ok i am seriously considering getting a wall built for street bass system not spl but a really loud system. Now what should i tune this to? also is having a wall in my car going to be louder , less louder, or the same as if it was in my trunk same size box and everything but in trunk. I am hoping for it to be louder. one main reason for wall is showing off/trying to kill base rattles outside and saving trunks space for tools/spare tire shit. But what i want to know is what should i tune it at and will it be louder or lower since its a wall. This car is a 2003 toyota echo sedan going to be ported box and will be using 3 jbl 12s gti's powered by a zapco 9.0. Now how i was thinking about getting the wall built was like this. Since it is a wall and i have 3 12's i should put 2 12's on the top with the port in middle and another 12 right under the port more the the bottom i guess how does that sound? I want the subs to be more in the middle and port in the middle of my box and middle height i guess right where my head sits on my head rest is where i want the port to be and the 3rd sub right under it or above it doesnt really matter how does that sound though?
