Right now I have (1) 18" MT off 2 JBL 1200.1's, and I want to get louder. Right now it is loud with music but I want it to be painful when I listen to it. It is painful to people who aren't used to it already, but I listen to it everyday, and I am used to it now.
I want to do this by adding only subs. I am keeping my same amp setup, because if I add much more, I will have to spend more $ in electrical upgrades, which I don't have right now.
My first thought was to add another MT 18", so I would have 2 with one amp to each. I know they will be underpowered, but I heard they are very efficient. I also am thinking of using my Circuit City accomindations to get 4 12" L7's or 4 15" L5's. I could also get 4 type R 12"s for very cheap. I have an Isuzu Rodeo by the way, and I don't care about going over the window line. I will do subs up ports back.
What would you guys do? I am leaning towards the 2nd MT idea at the moment.

with that power id sell the MT and get a Pair of 12" L7's. you can get extremly loud with l7's its all in the install. the 2 12's would slaughter the 1 mt due to power taht u have. its always better to overpower a sub then underpower. example i actually got louder from down grading my subs same box and amp. The cheaper less powerful speakers are way louder than my High powered sub woofers. i know its because i only have an 1300rms amp. and the higer brand subs are rated 800 rms Each. so they are way underpowered. But my cheaper subs are only rated 150rms each. im really pushing the chapers subs but they take it daily and are louder. if i were you id lean towards the l7's or Type R which ever is chaper hope this helped you alot. i speak with Experience, just trust me on this 1

wooooahk! I know you are trying to help, but most of what you said is off base. Im just going to go point by point and explain why. Not trying to be an ass, but rather just help our friend who posted above.

No they wont. 2.6kW is a lot of power, and if he tried, enough power to blow the MT. And why wont the L7s "slaughter" the MT? Reason being, you have roughly equivalent cone area, the mt has WAY more excursion displacement, but the L7s would have a motor strength advantage. Honestly with the right box they'd probably be within a few tenths of each other on the meter, which is something you can't hear.

If you have to do one or the other, I guess so, but neither conditions is ideal. Its best to give the sub its RMS recommended power. About the MT with 2400w rms, Im pretty sure that after about 5 minutes of quadding out, that the dustcap on that MT is hot and the coil is stinking. If so, he's at that sub's thermal capacity right now and should be looking at the subs excursion to see if he needs a larger or smaller box.

Putting them in the same box means nothng though. I take it you have access to a termlab meter? Put the more expensive subs in a larger box to get full excursion with the power you have and guess what? They'll probably be louder than the cheapers subs are!

As do I, on my own termlab. Tell me with 8.8kW rms what will be louder, 4 12" L7s or 2 DD 9915's? Truth be told the 9915s got louder than the 4 L7s did....by 0.3dB.
Install makes the difference and is the great equalizer, and is why we actually meter in the lanes instead of just looking and saying wow, that's gotta be louder than that. lol It is also why we say its all in the install - cuz it is!

If you dont care about going over the window line, wall it off behind the rear seats. This way you keep cargo capacity with the back seat, but you will gain a LOT of spl to the ear by walling it. Secondarily it also gives you a lot more room for the box. What size box do you have right now, port area, and port tuning?
I say wall it, MT it, and call it a day!

4) 12" L7's have alot more cone area than 1 18" MT, does that mean it would be louder?? maybee maybeee not.
your kinda in the situation that im in, I was pretty loud with a pair of 12" L7's and I want more but power has become a Issue, I upgraded to 2 15" RE SX's not done building yet so I dont know if its louder or not god with all this work it better be.
good luck with what you do, I know the L7's can be loud I also know that the MT's are Very loud with the right power.

I would get another MT 18 and put the jbl 1200 on each woofer. It will be louder than what you have. if you go with the kickers, when you get used to that your going to have to add more subs. with the MT's you can just add more power.
