Hey everybody...I just wanted to know what people have done in the past and see what worked best. I'm planning on putting 1-2 10" subwoofers in my trunk, and am interested in ideas for the firing direction, affect on SQ, etc. I'm trying to save as much space as possible and get great SQ.

well, I am going with 4 8" JL Audio W3v2 woofers.
It's in process right now and this is all I have, it's my getto microsoft photo draw, no skills system layout thingy. It should raise the floor of the trunk about 3-4 inches. And with space saved from not having the enclosure in the top, shouldn't be too bad. I'll have panels to put over the plexi windows and grils to protect the subs.

Right now I have two 12" subs facing the trunk. It sounds great inside but rattles a bit on the outside. I am getting ready to take out the spare and fit two 12" Solo Baric L7s in it. I highly recommend getting dynamat and any other dampening product you can get your hands on.
naw...I'm not looking for one solid frequency and huge boom. I want a really solid system in the K.I.S.S. fashion, that looks nice and is great SQ wise. I would just get a Kicker amp instead of the JL if I wanted boom...but I'm really looking for accuracy, better range, and great balance. Also...BUMP! Gimme some more ideas people!

FWIW my system should be done today and I can probably put some real pictures up tonigt
i've tried many different box designs in my pro. the 15 in a transmission line box facing forward sounded great and had some serious SPL. but i rather like the 6th order bandpass i'm using now with a brahma 10 facing back. it's got great low freq response and nice clear higher bass. if you are looking for SQ and boom, i highly recomend a brahma. or if you've got the money, check out treo, W7's, ID max, etc.
I'm really looking at the eDs right now, I'm just concerned with the placement of the box. I was gonna do a rear deck mount like on the stock msp, but firing at ass-end of the car. 1st had mentioned that this may cause some weirdness. I'm also worried that I may get rattle with it placed there, even on rubber isolation grommets. Hence the need for other ideas...I do want to conserve trunk space, as well.

Okay, I looked at it on my way into work today, and it's coming along very nice. I am starting to get excited about it. My system speaker wise will be pretty much done after this is over.
4 JL W3v2 8"s
Arc Audio 6.5" comps up front
Arc Audio 6.5" coaxials in the rear doors.
I can't wait to hear it this afternoon when it's all done and prettied up
And the two-way Clifford Matrix RS3 is kick ass too, works just fine with my HKS turbo timer

I haven't seen them yet. I'll let you know tonight when I see them out of the door. I was at the tint shop with the door panels off and if I remember correct they were silver. The fronts are actually coaxials (if I remember right), which is kind of odd since there are tweeters up behind the front mirrors too, wtf?
I'll post model numbers if I can figure it out from the speakers.

i use to install systems for a living. if you want good sq go with a free air or small inclosure style 10" subs and face them toward the rear of the car with the back of the box against the seat back. if your looking for apearance than you can mount your amps in the trunk floor with back lighting or something. and use fiberglass to create a flowing install

It's not finished yet, but it's pretty far along.

I'm finishing up an install in my g/f's 2000 Corolla which, as far as trunks and bass goes, very similar to a Protege sedan install. I've also helped others with small sedans...
There are basically 3 tried-and-tested ways to do a small sedan install:
1) remove the spare and place the subwoofers firing upwards
pros: looks cool, leaves plenty of trunk space
cons: no spare; unless you have a nice grill, you can't put anything in the space you saved; acoustical energy is lost in the trunk lid.
2) under the rear deck, facing the back of the car
pros: deep, deep bass. low freq. waves bounce off the rear and combine with waves not bouncing off the rear and double the intensity. still looks cool.
cons: very little midbass intensity. people with this config are crying for 8" mids in the doors or something to supplement it. You will contemplate over and over again if you should remove the rear speakers to let more bass in.
3) under the rear deck, facing into the cabin
pros: flat bass response, sounds great with everything except maybe gangsta rap that requires option 2 above. no intensity is lost in the trunk. your license plate doesn't rattle like on option 2.
cons: not nearly as much deep bass as above. May require more power to cut through the seat. only pratical for sealed enclosures as ported enclosures must be able to breath. doesn't look as cool as option 1 or 2 unless you fold down your seat to show others or you create a plexi back piece. passengers complain that their heart keeps jumping beats.
additional info: this option only works if the front of the box is sealed from the trunk. in other words you need to create a baffle that fills the opening between the trunk and the cabin, then you should dynomat the rear deck.
Out of these three options, I chose #3 for my g/f's corolla because she listens to soundtracks and pop music such as DMB. The deep bass wasn't as important as the mid bass. I used a single 10" Image Dynamics IDQ with 200watts from a PPI amp and it sounds great. It punches tight on bass drum kicks and has enough volume to play hip-hop the way it was meant to be played.
I'll post pictures soon.
Re: Re: Sub placement in Protege Sedan
Wow! That's the kind of answer I was looking for! The others were god...but someone picked up on my inexperience! w00t!
Now...I'm thinking of either #2 or #3...but let me get this right. In the above quote you mean if has to be set up like an IB system, except in a sealed enclosure. In other words...the front needs to fire directly into the cabin, not into the trunk? Note also...no speakers in my rear deck...so technically I could baffle it up through there...but that might cause too much rattle. Anywho...anyone have more comments on this?

Yes, it is exactly like an IB setup, only you get better power handling from having the sealed enclosure. Plus, since no bass will be in the trunk, you don't have to go to all the trouble of dynomatting everything like you would with an IB setup.
the reason #3 must be sealed off is because if it isn't...sneaky sound waves make their way into the trunk, bounce off the back (similar to option #2), but when they come back they actually cancel out the deep bass waves due to the orientation of the sub.
I helped a friend with his Audi A4 install. we had an older box that we used to test different configurations. We decided on option #3 as well even though #2 had significantly more low end. When we had the basic box completed we placed it in the car and tested it and it sounded pretty good. Once we finished the baffle to block the sides and the top the difference was amazing (with/without the baffle in place). Due to the way the opening was designed it was difficult to get a perfect seal, but when we finished the amp rack which further closed off the trunk it ended up being a great sounding system.
