From some kicker 10s in high school, its nice to now have the loudest bass at my college with a single subwoofer. Who needs back seats anyway? Incriminator Audio - Lethal Injection 15. Here was a video of me testing it when I got it all hooked up:

I am currently running 2 of the Soundqubed HDS 215's in the backseat of my mustang convertible. Do I like them? Yeah, but the problem is the box takes up my entire back seat and is way to small for those subs and tuned too high. I am missing a lot of low notes and I believe lots of output. I want to sell them and get a new box for a single 15. I am keeping the Hifonics 1700.1 but I need a sub to go in the box. I am looking at this box (http://www.ebay.com/itm/like/321813323806?ul_noapp=true&chn=ps&lpid=82) at 3.5 cubes total tuned at 32hz. (I can also reverse mount the sub for extra airspace) But I need a good sub to go in it, but I don't want to spend more than $200 unless it would really be worth it. So... Soundqubed HDS315 - $185 - 1200rms Sundown SA-15 - $259 - 600rms Lethal Injection 15 - $279 1000rms Or is there a better option for my money? And honestly, is downgrading to 1 sub in a better box going to be worth it? I love loud SPL but need some lower end quality.

Well, there it is. Very happy with the upgrade, I lost a little of the higher end notes as my car has low quality midbass, but I went from having hardly anything under 35hz to shaking my windows a little bit around 30hz. AND it gets way louder than my 2 15s. Love it.

The box recomendation on their website says .75 cubes, and 14~ inches of port area. Kind of small, but if you used a 4 inch aero port, it would have to be 24.75 inches long in a 1 cubic foot, after you calculate the displacment of the aeroport, it would have to be well over 30 inches. So its possible if you did an external port, you just cant fit it inside your box.

I got an email saying 10 business days, which would be today. Guess il be expecting more of end of week now, thank you.

So I ordered a lethal injection 15, with the spider option from SSA on Jan 31st of 2016. And it's now been a while and my order still says "awaiting shipment" I'm curious as to how long until I should expect to wait. I'm planning school and building the box and selling my previous system all around when I can expect the woofer to come in. Anybody know the build time?

I did set all of them to the same box and same tuning. And the picture was what I got as a result, after changing the tuning to 33-34hz on the Lethal Injection I am pretty sure I will be going with that one. The sundown is kinda wierd looking tho, not sure what happened. I filled in everything I could from their site.

Not sure how I would go about doing that? I talked to the guy about building a box, and Winisd shows the incriminator Lethal Injection topping out 125db and its the sub I am going to go with. He builds boxes allot and is convinced he can make it over 125db but in my car im not so sure. I still think ill love the improvment over my current set up. Which is its loudest at like 45-50hz and 30 you can hardly feel a thing.

^ oh wait, looking at "Gain" not "SPL" my bad. Still, im confused about the vent. http://i.imgur.com/fMpd1fc.jpg What is going on with the SA-15? and is the RE Audio SXX really a better buy than the Lethal Injection?

well im not 100% sure what im doing but i tried Winisd and im getting two very similiar graphs for the HDS315 and the Lethal Injection 15, but its showing for a 4 cubic box at 32hz, the soundqubed has a little more output. Also, im not sure about the vent thing, no matter what I change the size of the vent to the graph doesnt change.

I will do this later, I can tell just by looking that its not the best sub around but for having a 1700rms amp, whats the best Sub I can get for it without spending too much over $200? I like the lethal injection but from youtube videos im not to impressed. Sundown SA maybe?

lol, I picture some small child connecting panels of wood together by smearing glue on them with his hands. I notice the specs of the SoundQubed HDS315 are much different than other subs of that power handling. such as higher qts, and fs. I hear so many good reviews about them and their output and how they really can handle 1200rms, but why so cheap? and why are the specs so different?

Yes but as far as prefabs go, the one I saw on Ebay, the 4 cubes 32hz, has seemed far better than any other prefab iv ever seen. For one its actually large enough for the sub, and has a good tuning, also being made of birch. It also has a 1.5 inch baffle and port pannels are rounded off, and it has bracing. It actually seems to have real quality too it.

The guy im talking about works in a shop, and the best one around here, they work with high quality stuff and iv seen it in competitions, I was just worried about price. I am going to go there and see what I can get for my money.

Alright, well I did meet somebody my age who builds these boxes for competitions and for fun, and can give me one for $200 but it doesnt seem any different than this: http://www.ebay.com/itm/SOUNDQUBED-HDC315-15-Hand-Crafted-Birch-Ported-Subwoofer-Enclosure-/281889670394?hash=item41a1ef04fa:g:To4AAOSw5IJWdTzu But as a last resort, should I spend the $200 on that, or the $160 on the soundworks?

indeed, thank you. I'll see what I can get out of the local guy around here for $200 and get the best 4 cubic box I can. Thanks

Well the only guy around here that does custom ones will charge me @200 for the exact same box that i found online for $160. which is this: http://www.ebay.com/itm/4-CU-FT-CUSTOM-VENTED-15-MDF-CAR-AUDIO-SUB-WOOFER-BOX-ENCLOSURE-TUNED-32Hz-/360485922339 I know $160 for prefab is a lot but it looks like the best I can get for that money, and honestly I dont see anything wrong with 4 cubes at 32hz. Versus $200 for this: http://www.ebay.com/itm/SOUNDQUBED-HDC315-15-Hand-Crafted-Birch-Ported-Subwoofer-Enclosure-/281889670394?hash=item41a1ef04fa:g:To4AAOSw5IJWdTzu Which appears to have a larger port and wont go as nicely into my back seat but is it worth the $40 extra?

any objections to this? http://www.ebay.com/itm/SOUNDQUBED-HDC315-15-Hand-Crafted-Birch-Ported-Subwoofer-Enclosure-/281889670394?hash=item41a1ef04fa:g:To4AAOSw5IJWdTzu

Just got a reply from SoundQubed through email, I sent 3 options with links. 3 cubes with slot port, 4 cubes with slot port, and the 3.5 cubes with aero ports I have in the first post, and they said any of them would be fine but suggested the 3.5 cubes with aero ports. Not super specific but I guess that will work. I just hope for more low end without loosing much output. (which wasnt a huge upgrade over my 12s)

haha, yeah but it being where it is, its very hard to get to, and im at college and surprisingly dont have a measuring tape on me. I will try soon though.

39 x 18 x 16 (LxWxH) Not sure of wood thickness, but im pretty sure its 3/4 And I cant really measure the port but it goes towards the back and doesn't turn so its pretty short (under 16 inches) and pretty wide. Doing some test on music and tones, I am getting it to peak out around 40hz and maybe a bit higher. My subs are also reversed mounted to get extra airspace.

http://www.amazon.com/gp/product/B00C92PBHO?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00 This is my current box, with 2 HDC215s reverse mounted on top. I would love more output and low end. Does the new box look much better?

Currently running 2 HDS 215s (600rms, 15 inch) subwoofers in the back seat of a mustang convertible. Not much of an improvement over my previous Sundown E-12s. The problem I believe is the box. being obviously small to fit back there. Around 2 cubes per sub. Would I be better off getting a new box to put back there, say the QBOMB15VL where there is 3.85 cubes (4.2 total) for A SINGLE 15 rather than my 2 15s now. Also found on ebay a 4.0 box (5.33 total) tuned at 32hz. Also I could upgrade the subwoofer to something that can take my 1700rms amp better. Any help appreciated.

Well, I found a good one on ebay. its $150, and im in military college right now. Very little free time, no tools and no place to store anything. And being far from home im very limited with alot of things but shipping something here is about all I can do. I want to sell my box and maybe both 15s with it and buy a new subwoofer. Maybe make $200 for my current subs and box

ok, so I can get a 4.0 cubic box at 32hz, might upgrade the subwoofer too. I don't care for it to be perfect, just want some SQ improvement and to hit the lows better..
