hey yall, i have a 1989 dodge ram150. i recently purchased two 12" alpine type-r's and two pdx1's. i'd like to fit a ported box behind my bench seat. the bottom is 4ft long, 12 inches wide (bottom) 7 inches wide (top), and 20 inches in height. will it be possible for me to make a ported box within these dimensions? if so where would the ports be? and how many? basically i'd like to know what's possible and the basic construction of the box - or if there are any companies that specialize in older dodges! thanks for the help in advance, cheers.

 

can anyone help me out?
