[QUOTE="Bassphreak, post: 1746673, member: 567783"] How many subs total will you be using,2 or 3? Unless you can fit a box that is wider than 42" to 44" the don't count on being able to have three. What are the measurements of your trunk? Measure between the wheel wells and from the front of the trunk to the back of the trunk and how tall it is from the trunk floor to the rear deck. Three can probably be done depending on the size of your trunk or space. If you are for SPL then a bigger ported box is the way to go from what I have learned. Crutchfield recommends a 2 foot ^3 ported box tuned to about 33Hz and Alpine's 500w RMS Type R's manual recommends a 1.7 foot ^3 ported box tuned to 33Hz. I would say bare minimum 1.6 cubes per sub but for more SPL go with a larger box like 4 cubes or 4.5 cubes or even 5 cubes all tuned somewhere between 30Hz and 35 Hz. I am going to be building both Moe Lesters 4.5 feet ^3 tuned to 30Hz and the 5 feet ^3 tuned at 34 Hz. [/QUOTE]
