AF you can defiantly build your own box it's not too hard. Granted I might have a different view of it, as i used to ruin my own stereo biz when I was in high school and college and was also MECP cert.

Aas far as materials and cost for the build... it all depends on how fancy you want to get. For country music (as well as rock and well anything but rap) I would suggest that you stick with a simple sealed enclosure. they are the easiest to build and will give you nice tight bass. If you want to go fancy, go fiberglass, it is easier than you think. if you want to go quick and simple, go MDF. Either way you can build a box to your specs and make it look the way that you want.

If you go with glass, you will need MDF rings (to mount the subs to cause you can't mount directly to the fiberglass it will crack with the vibration) some fleece fabric to get the base mold, glass mat, resin, bondo, and paint or carpet.

the MDF rings can be purchased prefabbed (kinda expensive for all they are) or you can make them with a router and a flush cut bit.



Now you can go with a MDF base and go from there, or you can put tin foil down on the floor boards and mold to the contours of the floor for your base, and build up from there. just figure what base type you want and use dowel rods to position your MDF rings.



Once you have the position nailed down strectch your fleece over everything and soak it with resin. Onoce this hardens, a layer or 2 of glass mat and your ready for bondo and paint/carpet.

If you go MDF, it would be a lot less time consuming. take your measurements and go. Just make sure that you seal the inside of your box well with caulking (a lot of companies use a black tar type sealant, because it will remain flexible through a wide range of temps). being that you are not going to have a large box bracing should not be that big of a concern, so I wouldn't worry about it too much. Build up you box to fit how you like it, and carpet it with some automotive carpet adhered with carpet spray adhesive.

I have done several fiberglass enclosures as was as a lot of MDF boxes, it all depends on what you want. Let me know if you have any questions and I will do my best to help you out.

Thanks nate. If I do build my own, i'll be making one that goes under the rear seats.

Whats up with the cheap ones on ebay? Are those any good? Could I get one of those then tear it apart and make sure its sealed real good?

 

I don't know a whole lot about the ebay boxes quality, but when i was wheelin and dealing a high quality box would only set me back ~$50 for a 3/4" MDF carpeted box. There really isn't a whole lot of material in them and MDF is pretty darn cheap (~$20 a sheet) so they don't cost much to produce. If you go with the ebay box, just check to make sure that it isn't dinged up and there is minimal flex. Flex is your primary enemy on any sub enclosure. If they use 3/4" or maybe even 5/8" MDF it should hold up pretty well. if the box flexes you will get a lot of rattling and just overall crappy sound.

As far as making sure that it's sealed up well I've never had an issue with a prefab box not being sealed up. Nowadays everything is CNC so you don't have the minor imperfections in cutting out the pieces (like you might get if building by hand) that can leave gaps and or uneven surfaces that cause sealing problems. if your still concerned you can add a little extra caulking on the inside seams, there really isn't the need to tear it apart (cause you probably damage something in the process and have a fubar box)

I can tell you this af, you will be real happy with the RF P3, My box isn't quite prime for my P3, but its still a good box, and its only a single, but it sound wonderful! I love the way mine sounds, I almost had my local stereo store build me a custom box that would go in the same spot that would be larger and ported, it would have been 1.3 cubic ft airspace with whatever port they find works best. But then I decided to take care of other stuff on my truck. But whatever you find for your P3, it will still sound good as long as it is still a quality box with a reasonable amount of airspace. I think my box that I have right now has .9 cubic ft, and most people are pretty impressed by it.

And whoever the guy is that doubted that a single 12 can hit 140, you obviously dont understand sound systems, I have seen single 10's set up right hit 140. I have seen dual 8's hit 145. It can be done, has been done, and will still be done. For dbs its all about matching airspace with airspace with correct porting. whether you have a hatchback or a suburban, its still about matching airspace.

 

Yeah I've got a single 10" P2 now, and it hits harder than a lot of 12's i've heard. Ive been real happy with it until recently. I hate hitting the limiter that kills the sound completely when too much juice is pumped through. I want more subs and way more watts to be able to support the 2 subs.

 

dual 10 and dual 12 foxboxes will be available at the end of this month or beginning f june. said hed have them shipped by end up june/early july

 

no thanks. thats forever to wait, and only for the worst customer service anyone could have. he can keep his boxes and the lessons learned about how customer service is the most important thing when running a business.

 

haha AF, you should go over to d-talk and see the e-mail i sent him. its in weed's post in the 3g ram general section titled "fox acoustics gone as a sponsor" or something

 

yeah i guess it got his attention, but perhaps in a negative way. So the soonest he'll be shipping them is next month? How much does he charge for a dual 10"? I didnt see prices on his site.
