Just ordered my Z v.3 two weeks ago. Hopefully it'll be in this week. I'm putting 2 dual 2 15's in my 92 accord. I got D2s because I planned on running one amp per sub. I have four Planet Audio TQ1601s from my previous build so I plan on running 2 of them. I clamped one at a little over 1k before but a Z.v3 is rated 1.5k. I've seen where people dump 5-6k on them but I don't plan on using that much power. I plan to bump these daily and also do a some SPL (145-150db). How much power does it take to really get these subs going because I know my 1k per sub won't even tickle them. As of right now I'm thinking 2 DD M2's.
