I have plenty of tuning capability with the alpine pxeh660. It is more than just a line output converter. I can move the crossover frequency on each channel independently as well as change the crossover slope. How much more do I need?

The QTS of these subs is high enough to effectively work in an infinite baffle installation. With the trunk sealed off from the cabin the back wave will be completely isolated from the front wave negating any possibility of cancellation. The subs will effectively just be seeing a large sealed enclosure. Since I have no bulky enclosure I am only losing about 1.5-1.75 cubic foot of space in my trunk.

Also with the 8" in the front doors playing down below 50 hz the subs really only need to be used for the notes between 10 and 50 hz. There will be a lot less roll off below 20 hz than in a traditional sealed and definitely ported enclosure. If i so desired I could run these subs up to about 250 hz without any real roll off as well.

Plenty of Sound Quality built cars utilize infinite baffle. I have used it before in my own car so I'm trying something different this time around. Not every installation has to be done exactly the same. I'm sure my car will sound just fine

WOW! That's loud! You're in Florida and I heard it all the way up here in Maryland! ;-)

Really the hope is for the quality rather than the loudness. I still have a lot of work to do before I can turn it on.

Sounds like you know what you're doing, it just seems like your subs will bottom out on anything under 30-40hz. I've never seen free-air setups like that lol.

I've done a bit if research on it. The subs will only be receiving about 200 watts total, as they would bottom out with much more than that, since there is no enclosure to support the suspension of the subwoofers. That is another good thing about an IB setup. It is extremely efficient. That means I didn't new as much power, I won't be putting as much of a strain on my charging system, and I really won't need to turn things up as loud. There are a lot of positives, but the work that goes into it will not be as easy as just throwing an enclosure into the trunk. It will require tuning and additional work to get it to sound right. I'm okay with that because it will be worth it in the end.

Lol yeah. I use to run two 15" L7s on 2600w rms in a 10 cube net box ported tuned to 33hz with about 13sq in of port per cube. Got down pretty low and moved plenty of air, sold that and now got this 06 gt. Never really heard a good sounding system, but this one was the loudest I ever heard.

looks like its coming along nice man hope it turns out like you wanted

Some work done last weekend. I went out to changed the oil and ended up working for 8 hours or so. I got the trunk completed (all wired up), wiring run through the cabin, interior put back together, and under hood wiring done. All that is left is to mount the PXE-H660, cut the RCA cable to length, solder the RCA heads on, mount and wire up the under dash horns, install the 8" in the doors, and tune everything out.

So, I finally got around to doing a bit of work. I've been working on a five week battle with bronchitis. Today I mounted the passenger side horn. It was much easier than I thought it would be. It is mounted by three points. Two on the front attached to the dash under the glovebox, and one on the rear where the motor is. This is so solid it does not move when I try to wiggle it. I'm getting so close.




Driver side is mounted. There was an opening where the OBD plug went. I used a small piece of plastic and some CCF to fill the hole. Now there is a pretty smooth transition to the dash from the mouth of the horn.

Working on the driver side mid now. The mid is in the door without much of a hassle. The difficult part is getting the factory trim ring to sit over the new mid. I think I have some ideas for it.
So, all speakers are installed. Got the 8" peerless in each door. Made my own grills with grill cloth. I separates the chrome trim from the main ring, then applied the grill cloth. I think it looks so much nicer without the factory waffle grill.

All that is left is to put the speaker wire on the subs and to install the processor under the front seat.
