yeah those subs are really durable. they could handle double that power easily.
I have a friend thats running 1000/1's to 8w7's daily. no problems at all, they pound!
Those w7s are actually pretty efficient when they are ported, but can still take a buttload of power. Nice setup. And get on that tint before it bites you in the ***.
X1232312 on the tint...and id lose the w7 sticker in the back so no one jacks ur stuff...also i love your box looks great and sounded sick on 600 per sub
