Tuning higher does give more net volume, so Im all for that! House/Techno with strong builds is my fav music, but I do listen to rap and rock. You think 32-33 would be a good tuning?

Finally making some progress: Good news is the box will be larger than originally planned. Port area is 56.25in2, net volume is 4.48ft3 tuned to 30Hz. Is 30Hz too low? I still havent made the final cut on port length. Man I can't wait to hear/FEEL these suckers!!

Is the stinger no good? I figured it was better than the cheapo units on ebay. Thanks bass!

What is a good source for speaker wire and a Stinger display? Wire seems pricey at sonicelectronix and the like. What gauge should I use for the Xcons?

Will this be slight whistling at max volumes? I'm buying wood tomorrow. At least I can build the outside, while the guts still get sorted out I would just build it and see if it's okk for you. You might be content with it. It will surely be better than the Type Rs I have. Would 2 10s or a single 15 have been the best choice with the space I have?

Ok, Thanks! Is 50in^2 the lowest port area I should use? I have been aiming for 32Hz tuning, is that about right?

Yes, I'm going to use both 12s. So a side firing port design it is! Here is another attempt at Torres:

Yes, I have the subs. It may not be the best possible volume, but a great sound can still be had. So what is the best config for driver side focus of sound?

Yes these are the max box dimensions my trunk will allow and still be removable. So it looks like a slot port is my best option, correct? Any recommendation on which side or center would be the hardest hitting for the driver position in the car?

I wish I had that kind of space Bassink. Here's what I've come up with in Torres using 2 3" aero ports tuned to roughly 32Hz. Port length seems short, is this accurate?

After seeing the box Dave built for grayta, I plan to build one similiar. I stole these from grayta's thread, thanks! Are the honecomb looking braces necessary in the corners? Ready for gear: FInished product:

AMEN! Can't Fawwkn wait. Now would you guys please help me with the box configs? I want to start cutting stuff this week

Any foam in particular, or just the expanding type used around framing windows and door jams?

You can say that again! My wants far exceed my wallet right now. I already have the LC6i, which is only getting used for the sub amp at the moment. I'll check out the RF for the future, thanks.

Pic of the current box, which is 18x34x13.5. Door panel with factory 3 ways: Trunk lid, which needs serious deadening. Do any of you recommend any foam/filler to put inside the voids of the trunk lid?

No, I will right now. Thanks! Edit: That may be a good option in the future. Am I understanding it's function correctly: The PAC modules take the car's display outputs and coverts them to a display on a aftermarket HU? I also see a module for keeping steering wheel controls, which I am a big fan of.

Hello All! I was able to trick Santa again this year, and he kept me on the nice list. With some help from the gents at SSA, he brought me 2 new XCon 12s....WooHoo!! It's finally time for me to get building and put these suckers to use. This will be my first time building a box, but this creates a perfect excuse to buy more tools. I would like to reach out to you guys and get some experienced advice to help in my first quality build The car is a 2008 Pontiac G6 GT Coupe. It has the Bose Monsoon system, which isn't terrible for a factory unit. Unfortunately, all of the cars display features are integrated in the factory's HU display. For this reason I will be keeping the factory HU inconjunction with a line output converter. I'm using a LC6i now, but am open to getting a better unit. I know this is not ideal, but I do not like any of the replacement units offered, like the Metra. Here is my current installed gear list: Stock alt, Yellow top battery, big 3 with 1/0 wire, Audiocontrol LC6i, BC2000, 2 Type R12s, stock monsoon 3way fronts and rear 6x9s. The planned setup is: HO alt, 2/0 wire (already purchased), BC3500, 2 batteries, 2 channel amp and component speakers. I'm not sure weather to go 2 or 3 way for these speakers, as my front door is already built out for 3ways. Either way I have some time to work on that decision. Box Design: My current task at hand is to build the largest box I can fit through the trunk opening. I plan to fire the subs into the cabin, as my rear seats fold down easily. I have done a mock build, and the largest dimensions I can squeeze in there is 26Lx35.5Wx13.5H. I want removal to be easy, so the largest I would build is 25x35x13.5 as the Max external dimensions. This gives 6.6ft^3 gross. Calculating losses with a double front wall, .25 for port and .15 for each sub yeilds 4.74ft^3 of net internal volume. I am going to build a removable port assembly, so tuning is adjustable & I don't have to go through the process of building an entire box again. I have quite few question for you experienced builders/tuners: Is 4.74ft^3 a good volume for 2 XCon 12s? What is the ideal net internal volume for 2 XCon 12s? Should I double wall the face? I am building this for use with a BC3500 on good electrical. Should I build box out of hardwood (like Birch) or 3/4" MDF? I have no issue in working with either. I plan to face subs and port into the cabin with the port in the middle. Anything wrong with that setup? Thanks in advance for your advice here guys! I try to be thorough so I don't waste time & money redoing mistakes...DOH!!

Activities Rock!! I too run off the factory Monsoon amp in my G6 using an AudioControl L6i. Works well for keeping the stock HU.

Would you mind snapping a pic of this? Our trunk openings must be different sizes.

I found that if I remove the back seats and the black trimming around the back seat that I will have just enough room to slide it in there with no problem. I just have to build it and put it through the back door and then slide it in. If not.. I have metal bending tools that I'll use to get it in. It was the same problem I had with my 95' buick. I just took an inch off of each side of the inner trunk and pushed it in the back. Worked like a charm, plus it's extra snug in the back. I will double check everything with the measuring tape when I install my alternator today and make sure, I did it all by eye from the back of the trunk. From what I see, if you remove the black trim, you gain an extra 2-3" of width. I also know about that dip that you are talking about. I put that in my equation when I measured. My box is going to be at the edge right before it dips down, else the box would've been 15" h instead of 14.5". But I shall give you accurate data once I'm done. Ok Great! Glad it fits I didnt think the opening from the passenger bay was that big. I'll look at mine tom.

I would strongly recommend you at least fab up a cardboard box before you spill out $$ for one that doesn't fit. No way I see 39" wide fitting. Roughly 37" is my max trunk opening width, which does not take into account the narrowing in the bottom corners. 14" was the highest my trunk would allow for the box to slide all the way forward. Please measure yours with a tape and let me know what you find.

We certainly dig it! Keep up the good work & keep them pics coming

Thanks for taking all the time to document your incredible work!! I have learned a lot already, and now see the extent it takes to create a top notch build. I see quiet a few similarities in my Pontiac G6 with your Malibau. What did you opt for a battery up front? Our battery space configs are identical.

Hey there! I too have a Pontiac G6 I'm working on. I have an 08 coupe, so I'm not sure if the trunks are identical, but I would think they are close. I made a model box, and the max dimensions that would fit through opening are 26x35x14. This was with the spare tire mat/carpet out. I will probably make my box only 25x35x13.5 to be sure removal is easy. The headliner and rear deck are terrible rattle traps in this car, which makes subs forward is a great idea Imo.
