A:AnswerThe box is tuned to roughly 40-42 Htz. You will probably need a custom box for 33 htz since the port will be pretty long in length. (Example same box to be tuned to 33 htz would need a port about 25 inches long - give or take since it's 14.5 inches tall and 1.5 inches wide) Hope this helps.
A:AnswerWell first off you might wanna say where are you gonna put it backseat trunk I have the same box that I have in the backseat of my 07 impala and it takes up the whole backseat
A:AnswerNot unless you put it on the back seat I have a 2013 rs and it's way to big. But if no one uses the small back seat like me put it on the seat just watch out for the seatbelt buckels they break real easy.
A:AnswerThe box has a size on it. I honestly don’t think that it’ll fit under the seat but I could be wrong .. I had to put a little effort into getting it inside of my truck which is a Cadillac CTS but once it got in it’s a secure fit ..
