Thanks Yes, only one coil is hooked up. The second coil isn't powered. It is used to adjust the Qts of the sub with resistors.

This is a continuation of my work this weekend. I took out the amps and subs and started off my fitting in the factory carpeting and paneling back into the trunk. I marked off the clearance holes I needed to put in the trunk floor carpet to mount the amps. This is a shot of the panels and carpet in place. Nice and clean I say. Remember this is a daily driver. I use the trunk to haul anything from groceries to engine parts. This is where I wandered off the beaten path. I had bought the carpeting already at Wal-mart. It was like $10 for a 36" x 72" piece. Not bad. Later in the week I was at home accessory / craft warehouse with the wife when I came across some pre-cut fabrics on sale. They ranged in size from 36" -54" wide by 2-3 yards long. They had all sorts of prints and patterns. They even had vinyl. I choose this. Not bad for $6. Others might disagree on my taste. This is the first time I upholstered with fabric. Normally I use canned adhesive spray and layout the carpet. That's it. This time I had to also had to stretch and wrap the material plus staple it. It was pretty fun. I used an electric staple gun. I worked ok. The staples were T50, 1/4" long. I didn't want to tear through the fabric so I used a low force setting and tapped the staples flush with a hammer. Okay, okay, I'll admit it. I was just being a wus with the stapler. It was loud and it made me nervous using it. Here is a pic of my work. This is the finished baffle board. Back in the day I heard these called boom boards. Hehe. Here is the baffle and carpet in place. I ditched the nuts holding the baffle in place and went with some acorn-nuts and washers Here is an up-close shot of the acorn-nut and the fabric around it. I got the amps in place and cleaned up the wiring. I decided to mount the cross-overs underneath the rear deck. I was looking a little busy before, with the amps, subs, crossovers, and wiring. This will also help keep the wiring to the mids and highs out of sight. I love the optics of this pic. Looking through the speaker holes and seeing that back of the front seat gives this illusion of the seat not being straight. Seeing the door frame just enhances the illusion. Here is another shot of the crossovers. Also installed are the enclosures for the mids. The subs are finally back in place. I'm liking the contrast. Here a few shots at different angles. The sound is a little bit sweeter. There's nothing like a little pride to make the final result a wee bit better. Here is another pro for an IB system. No goofing around with a heavy box to get the spare out. Like I said, it's a driver and meant to be used. Thanks everyone.

Thanks everyone. The trunk lid seals up with the factory weatherstripping. Nothing fancy. Air tight? Not really. There's more on the way.

I cleaned up the install over the weekend. I started off on the mids. Here is a shot of what I started off with. These are the enclosures I made. They are ABS thermal-formed plastic. My flange was a little short so I had to modify the u-nuts. Here is the finished enclosure. Here is a test fit. Let me know what you think.

Thanks to everyone for you appreciation of this build. I know that it gets tough to here how people want to have their cake and eat it too regarding big output in small systems. Here I am wanting as big as I can get sounds without a box. Thanks for your gentle use of the flame throwers. I did clean the build up a bit. Here are some teaser pics. Let me know what you think.

I'm not too sure on the math, I'm still figuring all this out as I go. I know for sure my trunk isn't the recommended 10 times Vas. I don't know about venting the trunk, I don't think I have ever heard of that done.

These are the USB models. I'm not sure if Zed built the USB models or not. I've never opened them up to look at the board. For the youngsters wondering, no, these do not plug into computers. USB is part of the model number. They did the USA, then later USB. Cool, I did not know that.

Thanks. They've been bumping hard since '07. I'm starting to think about just reinforcing them with some 1/2" all thread. Who knows maybe it's time for a rebuild. Any suggestions?

They sound awesome. Gobs of out put. Boomey on rock music. I EQed them a bit using a Behringer DSP1124 eq. I got measurments using the Room EQ Wizard software from the Hometheater Shack forum. Night club levels, no problem. Poor cabinets, at full tilt you can hear the wood flexing. They're only 5/8" thick particle board. It's only a mater of time before one ends up splitting. Till then, no mercy. Muahahahahah!

Here are some bigger pics. Sorry for being such a noob at this. Let me know what you all think. Thanks for looking.

Check out my sig Check out my build here

I've seen these out there. The price is right. The specs are about par with my current Atlas. The AE15IB would make and excellent replacement if I ever burn the Atlas. I'm looking to make a step up. I have heard that AE offers a car version of the AE15IB. I think the VAS and the Qts are lower. That along with a 18 cubic foot trunk would give you and overall system Q closer to .7. I'm not the authority on any of this mumbo jumbo, but some say that a overall system Q of .7 make for a pretty good sounding system. I'm just not too sure on the AE sub because, they are still 100 watt subs with an X-max of 18mm and a sensitivity of 86dB. Which is what I currently have. On the other hand. The IB3 is a 500watt at 20Hz, 30mm x-max sub with a similar 86dB sensitivity. In theory if I get a pair of these and a 1000 watt amp how close to scratching 140dB will I get ?

These are the USB models. I'm not sure if Zed built the USB models or not. I've never opened them up to look at the board. For the youngsters wondering, no, these do not plug into computers. USB is part of the model number.

Yes, the seats are going back in. I was a little concerned that I would be losing output putting almost 4" of foam directly in front of the subs. Surprisingly the bass migrates through the foam without noticeable degradation in output. Granted my ears are human and it all gets interpreted in my head.

For me, making the video was an exercise in using video editing software. In my case Windows Movie Maker. It's hard to imagine that in this day and age there are some who have no experience uploading their own vids to youtube, I am one of those. I figure since I'm going through the effort why not show it to some of my pals and those who might be interested here, hence a pointless video of IB subs wanging. LOL on the sludge. It looks it, but its not. It's the factory jute insulation/deadening material. I don't how to describe it, it's like recycled jeans glued to a thin plastic sheet. In my car it extended from the floor up onto the seat bottom, then up along the seat back, terminating where the set back met the rear deck. I keep it on so the seat back frame would rattle against the baffle and angle irons. Thanks for looking.

After a little crash course in Windows Movie Maker I believe I've actually have something. Now don't go wigging out. These subs are rated for 18mm X-max one-way. Per the amp manufacturers specs, there's 240 watts going to each sub. Hehe. Now we're cooking. Let me know what you think

I bet. Your avatars keep getting better and better. Thanks

Here it is, a rare appearance of a classic, nuff said. The money shot. Another money shot with all the pieces in place. Please excuse my mess. It take a real artist to make all this wiring look good. A young grasshopper such as myself still has a ways to go. An up close a personal of the subs and amps. Stay tuned for vids, a clean up and maybe even some testing on a meter.

It's funny you say that, because I feel that is the most overlooked detail in trunk systems with mids on the rear deck. Kid's these are the details that makes a system worth while. Good thinking Impious, and thanks for bringing it up.

Thanks, no sound deadening yet. Definitely a next step in my quest for more with less. Now moving on to the subs. These are pics of my prep work. This is a shot of the trunk and what I have to work with. The center brace is going to come out. Here is a shot of the inside with the factory deadening material in place. It's just a layer of jute material with a layer of plastic. I thought I would have been more. Any ways, here it is. Some carnage. I cut out the center brace. I also trimmed the corners to maximize surface area. This is the foundation for the baffle. I started by welding some angle irons in place to reinforce where I took out the center brace. I followed up by bolting in some strips of MDF. These will act as spacers, spacing the baffle away from the rear seat giving the subs some space to stretch their legs. The MDF strips will also be the foundation that the baffle will bolt onto. The baffle, two layers of 3/4" MDF glued together with the sub to be flush mounted. Everything seems to be divided pretty good with the baffle and the factory design of the rear deck. There are a few large windows in the rear deck that I neglected to do anything about. From the factory there is a 1/4" thick piece of carpeted fiber board that goes over the rear deck. I think for now that will suffice until I get some deadening material.

"6th-order to the world" LOL! This is going to be good. I myself wander this world infinitely baffled. I am curious to see what this monster meters and at what frequency. Keep it up.

Thanks Lithium. It's nice to have the deep reaching bass without the box. The low power requirement is the icing on the cake. None of this big alternator , second battery, runs of 0 gauge wire, yada, yada, yada. Don't get me wrong, I myself have built the multi-kilowatt multiple 50 lbs sub system and loved it. It's the simplicity of this setup that I'm loving. So much for so little, what bliss. So if I add a little more? Will I get more bliss, or should I say bass? I'm eyeing theFi IB3. Almost double the x-max and almost triple the power handling but 3dB down on sensitivity. To be further investigated. Any thoughts?

Here are some pics of what I did at the rear deck The rear deck originally housed some 6 x 9's I opted to hack out the original mount and make some space for some adapter plates. Here's a pic of my hack job. I took the easy way out and had my adapter plates CNC plasma cut out of 16ga sheet metal. This is a shot of the adapter plates in place. Here we have the plates in place and painted with the components installed. Time for some reflections, words of wisdom by a lurker. I welded the adapter plates in place. Why? Because I'm a badass with a Lincoln Welder. In hindsight I should have just riveted and siliconed them in place. I would have simplified things if I decided to step up to something bigger. As for why the 5-1/4's to begin with? I scored these bad boys from and outfit called Deal Tree on ebay. They sell all sorts of stuff that has been returned or the packaging has been distressed and items of the sorts. Since everything is sold auction style I was able to nab these for $4 with $17 shipping. True story.

So I've got this build log going on. You can check it out HERE. It involves, dare I say, some old school Ascendant Audio Atlas subs. Taking it a step farther, I installed them IB style. Lastly, this is a, get as much bass as I can with 500 watts without losing any trunk space because I'm a sensible family man with financial limits, build. If you're interested check it out and let me know what you think. Here is a couple of teasers. Thanks for looking.

Let the rumpus begin. Here are some pics of the easy stuff, now that I finally learned how to post pics. Hehe This is the Cream Puff, in all her glory. It's my daily driver, very inconspicuous. It lays low from the law. Exactly what an outlaw such as myself requires. Here an up close and personal of the head unit. No flip down face, million button nonsense here. Just your basic CD player with RCA's. OK you caught me. It does have a seven band eq and built in HD tuner. Also the car requires unleaded fuel only. They don't build'em like this no more. Just to let you all know. That center cup holder / CD organizer was custom installed by yours' truly. A must when returning from my corporate lunches with an iced tea to go. Don't mind the mess, like I said this is my driver. Neglected and abused Here's a shot of my front stage. 3.5" Powerbass co-ax from e-bay, $30. True story. Thanks for looking.
