sorry for thread jacking, but im in a similar dilemma. i was thinking about getting a pair of assassin 8s or 10s. i have an idq12 in a ported box right now and i would like to reclaim some of my trunk space back. so basically my question is..should i go with two 8s or two 10s? i was thinking about 8s, but im afraid the bass wont be as good as the 10s, but with 10s, id need a bigger box than the 8s. and so on...hopefully someone can help me out before the sale ends =D
