well i dont have one amp hooked up right now and as far as the different subs its built like its 2 different boxes i have it split inside so that shouldent matter too much i had 2 smaller boxed and it hit pretty good so i thought if i made a bigger box it would make it a lil bit louder but its not as loud here are my old boxes

ahahahahh...first post ever, that has to be the jankiest shit I have ever seen. Getting over that-I would say that by the looks of things, you dont have a real amp, you probably ran 10 guage power, and they are probably wired out of phase...not too mention that, and oh yeah, you matched two totally different subs. What is the tuning frequency of the enclosure? You would be much better off to just get one good 15 than 4 mediocre 12s and underpower them. Sorry to laugh, but do a little research before you jump into something. Hell, one Type R 15, Titanic 15, or Diamond D6 15 would be better, and I dont think any one of those drivers are over 200bucks on the Intraweb. Do yourself a favor and cut loose of all that shit, simplify, get some room in your full size SUV back and start over. Build a proper box in the 3.5 net range for a halfway decent 15 inch sub, and you will be miles ahead in every facet. Please make sure you are running quality power of at least 4Guage if you are trying to get 1000 watts.

You say you have 7500 watts, well lets just get a realistic picture of that....you would need probably 2 LARGE alternators, 5 or 6 batteries and multiple runs of ZERO guage power to feed that. If you have a flea market amp...which is likely, you probably have in the neighborhood of 800 watts-If you are lucky. Start over. There is the cold hard truth.
