Are the 2008 L7's 2ohm better than the older ones. I was planning on running two 10" L7 2ohm in my fx4 with i seat lift, but dont really have that much money. I can afford the 2008 subs if their better. And then also is it no going to sound as good if i run the zx1000.1 over the zx1500.1, or do you guys have a better option that is cheaper. Because with the subs, amp, seat lift, custom box, install, im going to be looking well over a grand. Any ideas on maybe the older L7ls or amp??
