tuned to? guess i dont quite understand the question.. It gives about a half a foot or so on each side of it, In my grand am 2002.. to give you the idea size.. If you have any specific box suggestions, that wouldnt be bad either.. Like i said, im not really limited on money, its my choice on what i spend money on.. Im just not the kind of person who wants to blow 1,000$ on there system.. I already bought some new component speakers.. Spent about 700-800$ or so total on those.. So thats why im being choosey on what route i go, to do my subs now..
But the idea of a mono block amp, running to the two type-rs, is a fine idea.. Is about the same amount of money all in all.. EVEN if i buy another box probably
