Update and long term results...
Just wanted to update this thread with my latest mod- I added the PIE Mazda-> Alpine adapter box combined with the Alpine-> RCA adapter cable for a seamless line-in for my RCA 40gb Lyra mp3 player, and my system sounds fantastic. Details on that mod can be found here:

Also, I'm still running without a line-level or line output converter and have had no problems whatsoever.

Id like to see your plans in GIF format. I have a pair or Kappa Perfect 10.1s and Id like to make them fit. the 65degree slope is great to know. How many cf is each section of the box? mine need .60 each. i have a 600W JBL powering them, did you need a cap?

i must have missed that, thanks.
as for remote on: many amps have auto on from high level inputs... if you use speaker level inputs instead of RCAs , your amp should turn on only when it recieves an audio signal, this eliminates the need for remote leads.
Does anyone know how much watts go to the 6x9s? I dont want to mess up the inputs with too much power.

As for the power to the 6x9's, probably depends if you have Bose or not. I think you'll find the signal cleaner if you tap into it before the amp instead of speaker level.

Still no word on whether you would make one of these for sale. Honestly I'm completely audio retarded and didn't understand 1/2 the things you guys were talking about here, but I do want to learn and am trying to piece things together. I just know I want a sweet system, and you have the best looking one I've seen so far. Thanks

Hey i got a question that probably was answere somewhere else but im lazy....Ive been wanting to install my 10" Type R's but i stoped by a local shop and they said that with the bose system you would have to replace the wireing and **** to hook up the amp! Two places have told me that now...is this bullshit or what? If it is true then is there a not horrible explensive way of getting around it?

Rca connections?
[QUOTE=G8rboy]Nah- that's BS... tap into the pre-amp wires I showed in the pics on page 3 coming from the head unit, and run those into the amp's line-level input. I've been running this setup for almost 2 years now with no problems... no line level converters or other wiring... nice and cheap [/QUOTE
i want to use this setup but the amp i want doesnt have speaker lvl connections only rca imputs. How do i wire it with rca connections?

Preamp input into Line-level vs Speaker-level
I just installed an amp and a sub today. Initially, I was taking the preamp (Bose) input into my subwoofer amp (which is a Profile HA700M) high-level input. The result was very weak bass. It does add some overall but not what I was looking for. Then I redo it by hooking it up into the line-level input, the difference is the world. I would just like to share this experience with you, so that you don't freak out when you got weak bass coming out. Thanks everyone for contributing to this thread, it was very useful and assuring.

So I'm a little confused now after all this..... all I have been reading on here says that you must use a summing LOC such as the Audiocontrol LC6i or such....now you're saying I can use any ol LOC or even directly into the amp (if supported)? What would be the advantages to using the LC6i? Just more adjustability? Not worth $100-$200 and pain of installing IMO.
EDIT: Also found a similar box on Ebay. Looks a little better even. No offense, but it's fitted to the RX8 perfectly.

I have a base stereo, how should i go about getting RCA output, ive already found a remote signal turn on that runs from a speaker signal, but do they make line converters from regular speaker wire signal to RCA output?
any help is greatly appreciated

Question for you all. Getting a remote turn on for your aftermarket amps. I realize you can tap off any acc power plug, but those with the Bose system should have some other easier options correct? Measuring with my DMM at the Bose harness, I noted that the yellow/white and pink/black wires are hot only when the key is in the acc mode. Makes no difference if the headunit is on or not. Anybody know what exactly these two wires are for?

i'm suprised this thread is still going after over 3 years LoL..
Try going on ebay and search for "RX-8 Sub" and check out this box i found...
it's a lil too small to add ports (if you don't know, most ported box volumes should be almost twice the volume of sealed boxes) and i wanted to build a box with a rear center-firing slot port with a custom port mounted on that rear center access panel going straight from the interior to the rear of the box. I'm working on designing and then building a deeper box with a custom fitted baffel that will add about .75 cubic feet to the volume..
Most likely i will just buy a box and modify it with the added port and baffel.
unfortunately i will have to add that on after i put the "main" box in the trunk so removing it is gonna be a pain in the *** if i ever have to, let alone installing it in the first place.
With it i will be installing a pair of MA Audio HK120xc subs and powering them with a MA HK1998 1200 watt amp...
but first things first... buy the wood and a spiral saw. I'll post pics next month or whenever construction starts.
For those of you who want a sealed box, that ebay listing is worth checking out

Already way ahead of you. Got one with a single 12" hole justified to the driver's side. Cut a 4 1/2" circular hole and added some 4" PVC piping. Tuned to 32Hz and sounds awesome. Not only is it louder than it's sealed counterpart, I get much better low frequency extension. The subwoofer I choose plus the semi-low tuning freq makes for a pretty evenly flat roll-off at all frequencies. No annoying overly-powerful thumps at certain parts of certain songs.
