Answer to this question is I still use my back seat for an extra passanger, and for the position i like my sub in i cannot put it on the gound because of the position of my amp, if i had more movement with my amp i would remove my seat, guess i just need to play with it more just really dont have the time
And thanks anyway dalton, glad you tried, and the box the guys buildin is around 4-4.5 cubic feet tuned to 35 hz, he kept tellin me i shouldnt go below 38 but i said fk you put it 35 lmao..
-will gladly post pictures after its installed, should get a call sometime this week about the box
