Take a look into what everyone is saying and do you have anymore goals besides I want two subs that can take 3-4000 watts a piece. If that is the case then look into the: Sundown Nightshades (Nightshades v.2 will be out within the next few weeks), Fi BTL, AA Mayhem, IA Wardens or AA SMD's just to name a few.

Do some reading and searching on this forum as well since there is a lot of information that may answer the questions you have such as this one (by the way there is no best 3000 watt sub if that was the case there would only be one of them).This is your system and you can do it how you want just make sure you do it right, make sure you have a well-constructed enclosure, wiring on par, electrical to back it up and sense on how to run the system so you know what your doing. Ask a lot of questions to make sure everything is right even if you have small doubt, now that you got a plan all you have to do is execute it.

Hey, thanks man.

But for everyone else, After reading this I am planning on a single 18 and an AudioQue 2200D. Would a DC Lvl 4 XL do fine? Yes I will have the electrical to back it up. And I'll make sure its clean power

Find out what Jon is asking for his NS.

I just like watching this vid you might learn something you can have a decently loud daily driver and have a loud car as another. But you never need a very loud daily driver one your never going to be bumping so loud why because cops and stuff.

sold !

Okay, thanks everyone that actually helped

I'm looking at doing 2 15" XL's starting on an AudioQue 2200D. Again, thanks everyone that actually helped me out.
