two of Ill's sub boxes, one on each side. this will allow for two 10" subs and plenty of room for the t-tops. I have an awesome 10W6 in a Powerwedge box right now and am going to either pull it out of the box and use that along with another 10W6 or just buy two 10W6's. But, the 10W6's are awesome subs. I don't remember the price, but I used to have this single 10" sub in my trunk in my 240SX conv. and it was good base from back there, so 2 of them in the hatch will be huge base. By the way Ryan, I'm going to need some help with an install of my Kenwood media system next month if you're free. :-) Also I was using a mono channel Kenwood 816, good for 400 watts I believe. Great amp, I'm either going to look for a matching amp or a replacement that can handle both subs.
