i found a 7 inch dual stacks ki, and i was just wanting some oppinions. I've always been intersted in getting stacks, and i always figured i would go with a 5 or 6 inch. however i came across this 7 inch kit. i know that 7 inch is huge, but in your oppinion, is it too big? i think it would look pretty good bellowing out the smoke. what about sound? is it going to be too loud behind the cab? I've never seen a set of 7 inchers on a pickup, and was wondering if it would look to rediqulous. anyone have them or seen them? what do you think?
