ahh... didn't notice thnx.

Max Dims are W=50 H=25 D=30. I guess I don't really understand. The bl gets louder with the same power handling and cone area? If the XmaxX is greater on the Q then shouldn't it get louder due to more air movement? You guys definetly know more than me though so I will get the BL's then. I'm sure I will not be disapointed with either one. Thanks for the input.

If you could explain why, I would like to know.

I only really listen to rap. From the floor to the ceiling it is 39". I was thinking of making the box 25" Height. Is that enough room from sub to ceiling? Should I keep the box lower? To answer your question a little better 11-12" above where my back window starts.

Ok, measured again and I came up with 15.7 cuft internal volume after speaker displacement but without figuring bracing or port. Should I still tune the port to 32hz BKO?

What would the difference be in having 14 cuft or 20cuft?

That's what if been hearing. That's why I want to use them. So for the 2 Q 18's, does anyone have enclosure size suggestions? I guess I will make whatever size box that will sound the best on those speakers. If 10cuft a piece is what they need to sound right then I'll do it. I wanted the port tuned to 28hz right? Or would you suggest a higher freq.?

I have a 04 expedition. I guess what I'm going for is something that sounds good but will still hit the lows hard. From reading around I thought that the Q series sounded good and still had the ability to get somewhat loud. I could be wrong. What dimensions were you running in your expedition for your box? That seems like alot to me. I really wanted to try 18's out. I have never seen nor heard a 18in woofer. I'm pretty sure I won't be dissapointed. I do care about everyones opinion and I really appreciate you guys taking the time to try and help. Bare with me, this will be my first big install so I'm trying to make sure I have everything planned and set in stone before I start spending G's. Well big to me.

I might be able to pull off 13-14 cuft before displacment. I'm trying to avoid lossing my back seats considering it a expedition.

I think I'm just going to get the 2 18's. I had one older alpine type r 15 in my 97 eclipse one a lanzar optidrive 2500 and I thought it sounded pretty good.

Okay, so start pointing.... I'm open to any and all suggestions. Don't forget my main goal though, the cleanest and loudest low end bass in 12 cuft enclosure on 3000watts rms

Sweet, what kinda power were you feeding them? What kind out electrical did you have?(atl size, how many runs of 1/0, how many batts)walled or not

I'm sorry that you couldn't understand. Is this better? It's not like I'm writing an paper for school. I would still like some feedback please. I thought this was a reasonable question. Either you have 2 18's with 6 cuft a piece or you have 3 15's with 4 cuft a piece. The 15's are rated at 2.8-4 cuft @ 28-33Hz per speaker. The 18's are rated at 6-10 cuft @ 28Hz per speaker. If I only have 12 cuft to build a box then I need to know if 3 15's in optimal conditions would be louder than 2 18's with less then optimal conditions. THANK YOU to everyone that helps me out.

yes spl as in im not going for 160db just whatever will be the loudest but still sound clean and hit LOW so i will be running the subs with 3000watts rms ported enclosure tuned to around 28hz in a expedition i and tuning with a audio control DQXS so in the same cubic feet and with the same watts with the box in the same location 6-10 inchs from real tailgate subs firing up port firing back
