Guess I'll go with a single ixl ported then. Aren't you like the mach 5 owner(I'm a noob lol, correct me if I'm wrong). If so I'm happy to know that the company I'm gonna be buying from has such great people backing it. Thanks for all the help man.

Well I have 10 or so cubic feet of space. So I could pretty much do ported or sealed with w/e I choose. I'd kinda prefer sealed for a bit more sq but I could go either way. Thing with the ixl is that I could always add another if I ever wanted to get louder. Problem is that with two ixl 18's I'd be cutting it pretty close space wise. What's the reccomended box size for two of them(ported and sealed).

I've got around 300 to spend on a sub and am looking to get a decent s ql setup. I don't plan on upgrading my electrical so I'm trying to stick around 1000w. I want sq so w/e I choose will be put in a sealed box in the back of my extended cab toyota t100. I'm very interested in the mach 5 subs. How would say a ixl 18 compare to a fi q 18? I'm considering a single mach 5 ixl 18 or 15 with 1000w or 2 mach 5 mj`8's off of 1000. Which setup would get louder? Which would have the better sq? I'd really like to get to the 140db range but I'm not sure if it's possible with only 1000w sealed with these subs. What do yall think? Any help is appreciated.
