The Kicker box is not the correct size or tuning, I put my 7500 12s in 3.75cu/ft tuned to 34hz and they did ok, I should have put them in something closer to 4.5cu/ft with a higher tuning. I have heard they like big boxes (over 2 cu/ft per woofer if a 12) They will get loud, but they don't really like to get low.

should they be in a ported box still? and wat shud the settings on amp be? its has spl, subsonic, db. and what ohms should i run the subs? thanks for the help btw too. ill hav a bunch of questions if u wanna help. wat exactly are the dimensions you said above? like wat kind of box would u suggest and how big ? length/ width/depth/height. i want the subs to hit like there suppose too.

I'm sure that it isn't that no one wants to help you, it's simply that you have asked a blue million questions....many of which you can answer for yourself by doing some research and reading already-existing threads/posts.

Locate and read your amp's manual; plug your sub's specs into an online enclosure calculator and see how far off your box may be; decide what you want from your system before trying to set it up; calculate what your electrical can handle before deciding at what impedance you're going to wire your subs; read the Sticky on setting amplifier gains before you start running your system and take a chance on ruining subs; and etc, ad nauseum.

My suggestion is that you do all the above, spend a lot more time on here reading/listening, and find a knowledgable person local to you to offer specific advice , or even assist with your install...

first of all, all that u said didnt help me one bit with any of my questions. Basically a waste of ur time n mine. and ive looked up a lot of **** and its all hooked up legit and pounding hard enough. dude said i shud use a dif. box so i had some questions about it. n i bought my amp from a pawn shop so i dont have a manual with the subs or amp. maybe instead of questioning me y i have questions n tellin me to jus go look it up elsewhere y dont u help or not waste my time. what do u think this site n thread is for neway? i made the thread asking questions to help myself not get criticized that i should of did more research. ive done as much as i kno to do with the system. im gonna do the big 3 and upgrade on the wires but when it comes to hz n wat type of box my subs shud be in, it is a simple question that cud b answered by someone that has had a setup like mine. n asking about the ohms n stuff like that, i already kno wat ohms my subs run at but was merely asking if how i had is indeed correct. cause personal expirience is better than a manual any day.

Well, as far as an enclosure goes, they work well in 2.25 cubes a piece at 33 hz with 14 in^2 per cube.

Your amp has your gain, low pass filter, and subsonic filter. Gain setting depends on a few things, like what voltage your pre-outs are. The subsonic filter should be set around 27-28 hz in the box that I said. Any other settings like bass boost should just be left all the way down.
