firstly let me say bsw make some very nice upgrades and there a perfect fit.
however by being a bit adventures you can get a baffle plate made to fit in the ski hatch and fit a nice 10" powerfull sub in there.
id max makes the perfect sub for this and almost any amp will run it.
or you can get cheaper subs and still keep your bootspace completely

Dave,

This bracket will accept ANY subwoofer upto 12". All you need to tell me is the cutout of the sub which is always smaller than the actual sub diameter (you can measure this or look in the manual that comes with the subs, they all have a dimension sketch.).

If you are hooking up only a subwoofer and using a dedicated amplifier (mono or one channel amp is all you need), YOU DON'T NEED a crossover.

I think BSW's solution is overpriced and underpowered. You are paying for the plug and play and nice fit in your trunk, but for $400 which is what they charge, you could easily install at least twice the power that they offer and with better components (they don't use any known subwoofer brand such as JBL, Infinity etc... and they use paper cones vs. glass fiber on Infinitys or even better materials on JBL's etc...)

Best place to start, is call Crutchfield, they'll educate you for free. Then go on amazon and buy the stuff, then order your bracket from me

I'm sure there's plenty of wiring guides and speaker comparisons in the ICE forum. But vert-specific subwoofer suggestions that could use this bracket, or links to them, would be a nice addition here.

It will depend on the amp if you need a seperate crossover, if the amp has a built in sub crossover you will be fine withought a seperate one.

garrafa,
I see two problems with your solution.
1) it is surface mounted. Which probably means the sub will hit the rear seats, and you can probably not run it with the center section in place.
2) it looks like it leaks like a sieve. You can't have a proper IB sub unless the back is isolated from the front. Looks like your solution leaks above the sub, and, through the triangular cutouts behind the sub.
Just starting to look into sub options for my vert. so I welcome your comments on my comments. For now, just duct taping the HK sub door shut helped a lot. I'm thinking I want something that sits flush (so I can use with center rear seat in place) and seals trunk from cabin so at least I can simulate an IB. Or, I might just build a small box. Or just buy BSW (when you think about it $50-100 for box, $150 for sub, $150 for amp and you are pretty close to what they charge. And they they've taken care of R&D - might be worth it. . . )

I had the same concern about the sub not being totally sealed and was planning on sealing it with Dynamat but after initial testing, found that it sounds very good without the Dynamat. I went ahead and sealed it with Dynamat and found that the sound was not particularly better. I'm personally very satisfied with the way the sub sounds (note that this Infinity Kappa sub is a "free-air" design which is made to work in not airtight compartments such as in this application). I think your comments would be more valid for "regular non-free-air subs". Again, sealing is just an extra step and easily done with Dynamat, but I found it was not necessary in this case and given the free-air design sub.

You can run sub with center section in place without it hitting?

A decent 10" sub, amp, and wiring will run you $400, plus $75 for this bracket. Yes BSW is expensive, yet compared to similar quality its not that expensive. Sure you can cheap out on a sub and amp for $200, yet you get what you pay for.

To be exact, BSW costs $659 vs. about $385 for your own custom setup below:

Now, compare power: BSW does not even disclose how much power their sub can handle on their website (correct me if I'm wrong). If you buy the setup I recommend below, you get a 12" sub guaranteed to fit your car with 350 Watts RMS/1400 Watts peak and an amplifier to power it adecuately. I doubt BSW has that kind of power and they only offer a 10" sub. There is a big difference between a 10" and 12" sub, you will surely notice it. I also know that BSW uses paper cones on their subs.

The suggested Infinity sub below uses glass fiber weave, which is much stiffer (for better sound) and even looks better. One more question, what brand of amp does BSW use? They don't say. By going custom, you can have full control of what amp and sub you buy, JBL is the best and for less money than BSW. With BSW, you are stuck with what they sell you and unknown output specs.

My recommended shopping list:

AMP= MTX TH350.1D (350 Watts RMS, 750 Watts Peak at 2 ohms)=$135 on Amazon or Crutchfield

SUB= Infinity Kappa 12" (350 Watts RMS, 1400 Watts Peak at 2 ohms)= $175 from Amazon (less expensive and great subs available too, or you can go all out on a JBL sub)

Bracket Kit (includes metric bolts, washers and instructions)= $75

-----------------------------
Total $385
(compare to $659 for less power and smaller & paper cone 10" from BSW!)

Does the 12" Kappa take up as little space? How does it sound? Quality of bass, not quantity. How does a 350w sub integrate with a system driven by stock amp and speakers that is surely much lower powered? Would someone who is interested in the top to bottom quality of sound rather than window-shaking bass be content with that setup?

Both the BSW and the Kappa protrude into the "tunnel" to the trunk but don't actually protrude into the trunk, so no, it doesn't take up significantly space than a BSW. Look at the posted pics and compare with BSW pics.

This 350 W amp or similar sub needs its own amp, any OEM amp will not work (BSW also includes an amp with their sub, they don't run it off the OEM amp)

It is nice to have the capability to create monstrous bass, but you can keep it low as well, either way, it sounds incredible, but only you can be the judge of that given that each person has specific tastes. In my experience, this sounds great with all types of music (from classical to country to rap to rock) and at all levels (recall you are using name brand components which are higher quality than BSW and more powerful).

It has now been advertised in the classifieds section. For $75 you get more than a piece of wood, you get a Kit. The wood has been precisely cut and designed to fit your car and any sub up to 12". You also get metric bolts and washers to install it as well as instructions.

I found a post where you're advertising it for $50, why the change of price?

Also, could you post up close pics of the sub with the seat installed. Most that have installed a sub in the ski pass have built a triangular box with the front recessed from the metal so that the sub does not hit the seat or removable section of the seat.
