yea but its actually was just a temp install for my fun car so i wasnt too serious, im lookin at for next summer fiberglassing either 1 18 or 2 12 into the back hatch ported
No need to make the box bigger if you want SPL....if you want more out your daily box id go to around 35-38hz...still get some lowend and have less peak at the higher end
I know when i had my R15 in 3.5cu and 32hz it peaked at 36-37hz and dropped off fast after that....but when it was at 35hz it was alot better around 40hz and less peaky
