you should have no probmlems with that setup nismo. its ok to overpower your sub. its better than grossly underpowering it. im probably going to start a war on this one but here goes. mostly what happens with blown subs is underpowering and distortion. that is when you bottom out the voicecoil and get perminent damage. just make sure you gain is at the right level (not to hot dont want to clip your amp) and you be fine.
