if i put a 800w sub with 1000w amp in the trunk will it hit pretty decent where you can feel it and hear it or is it a waste of time? and how to you have your box set up. ive see the most common where i guess they take the jack and stuff out and put a box in there so it sits flush with everything back there but i would like to fit two 12s in there like i had in my accord but how small it is back there i cant even fit a shoe box back there. pics would be cool as well. just trying to see my options. thanks
