Hey guys,

I have been into car audio for about 5 years now and I believe I am fully ready to to do what I would consider a high end setup. I currently have a 2002 Hyundai XG350L with my 2 mtx 4500's, alpine amp, and rockford fosgate p1 components and 2 ways in the rear deck, with a P300.2 powering them. I am getting ready to move into my parents new house within the next month and will have a full size garage to work in. This will give me the place to let my mind expand and come up with ideas. I have been looking around at some new subs, I Have a couple of ideas in mind but am open to any suggestions as I havn't heard any system bigger then 2 cvx's on a JL 1000. I am going to be doing the system in peices due to being a broke college kid and having to work my way from nothing starting in may. I know that the first bit of info I should give you is what I have for equipment and what I have for space. The trunk in my car is fairly big IMO. But the max dimensions that I am looking for are 38"w,17.5", 22" deep(max). The kicker is I want to seal the box from the trunk and have the port firing through my rear seat armrest console. I would have to to some mods too it (cut the port hole out of the seat) but I am very handy with shop tools and have confidence in myself. I essentially want to take the 5 seater and turn it into a 4 with the center arm rest permanently mounted. This would require having the port extended outside of the box to get to the port hole in the seat. I have come up with some sketches in google sketchup but am not sure if they are one hundred percent. I am asking for advise on sub's to fill the gap, I want good sound quality with the ability to hit the low notes. I was originally thinking 2 AA havoc 12's. The box with those dimensions would yield 4.9 cubic feet after displacement, including 4 1" dowels for bracing, which would be right at the top end of what AA recommends for enclosure size. I have read many positive reviews about these subs and think that they seem to be what I'm looking for. They have the sq and the spl which makes for a all around sub in my opinion. I was thinking of getting either a sundown SAZ2500 or 2 SAZ1200's depending on the pricing at the time of buying. I am willing to do a HO alt if needed but I want to first see what my car can take. Big 3 has been done already in 4ga. but I plan on redoing it in 0ga. I am gonna get at least one big battery in the engine bay, was looking at the XS d3100. If I need a second one after that I will go down that road but like I said I want to see what my vehicle can take, so a voltmeter will be needed. I have also been looking to upgrade my front end which is where I want to go active. I have a couple of amps that I can use to start and will need another one. I have a rockford fosgate p300.2 and a RF p250.2. Both of these are solid amps, they have been put through the paces and never let me down. I was thinking of using the p300.2 for midbass(SA 8"neo's when they come out). For midrange I was looking at these: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=264-889, I can run them off my P250.2. The tweeters and amp are still up in the air, I am open to suggestions. I was looking at the Audiocontrol DQSX, I would run as the description says, i would just daisy chain the audio from the midrange amp to the tweet amp, which I believe would work. I also have an Alpine CDA-105, and I plan on doing sound deadening throughout most of the car(cabin floor, doors) I guess what I am looking for is if I missed anything important. I am open to any criticism (good or bad), just let me know what you think of this plan. thanks. I also cant figure out how to upload the box design picture, any help with that would be great.

I'd ditch that mid and get something more sensitive to keep up with those Sundown neo midbasses. Not to mention those midbasses are more PA style woofers, so you should be able to run them higher than what you'd normally think of with an 8" woofer...there's no need to use a midrange that adds more mass so that it can be crossed lower, in my opinion. I'd look into the cheaper version of what you linked to, the ~$65 one. It's more efficient and still has a 1.5" coil. If you're bandpassing it in the 500hz-5khz area you'll be able to dump a lot of power on it. Don't be thrown off by the 35 watts power rating, that was done full-range with no crossover applied.

As far as tweets go you can go with high efficiency there as well since you won't need it to play but 5khz and up. There's some Vifa semi horn loaded tweets that were for sale cheap at madisound. They were 93db or something like that.

This is all assuming that you want high efficiency to keep up with a loud sub setup, and that those Sundown mids are clean up to 500hz.

You are assuming correctly that I want to keep the efficiency up with the subs. I like crisp clean highs, but want that punchy midbass that the neo's will create. With the neo's should I fiberglass an enlcosure in the door for them, or should i let them run free air in the door cabin space? I havn't read much about them I just know there gonna be good haha. The horn tweets sound good to me as far as I know. Do you think the Audiocontrol will be the proper eq for this setup?

I'm not familiar with what kind of crossover points you get with that particular AC unit, but being an AC unit I imagine you'll have a ton of flexibility and any kind of frequency/slope combo you'd need to properly execute this setup.

Ok yeah thats what I figured, it has everything available from what I see on their website. What about the question pertaining the neo's? free air or fiberglass enclosure? Im assuming that an enclosure would work best so that they have something to resonate off of.
