The new Q's get super low and load as hell doing so. Mine is in 3.6 cube tuned at 29hz and the output and clarity on the low notes is amazing! I am sure the Xcons are great too, but your fist choice will do exactly what you want in an impressive manor.

I had two 12's back in the late 90's that were very nice!

You are probably gonna need more airspace and tuned lower. I am not familiar with those subs but 1.6cu seems small for a ported 12. 2.5cu at around 28-30hz would be better I would think.

I cannot imagine how this will sound! You will have to keep wrenches and tools in the truck just to tighten things up every few days, lol.

Well, after many questions and research I guess its time to start a build log. I havent done this in over 12 years so its alittle slow going. This is going into my daily / work truck. I am not necessarily going for "SQ" or for "SPL" but something that sounds good to me. Not a big build or anything. Here is the truck it is going into. What is being replaced. Center console will be coming out. The equipment that will be going in and some that was already there and will be staying. * indicates new equip Power and wiring *30ft of 1 /0 KNU Kolossus OFC Power *20ft of 1/ 0 KNU Kolossus OFC Ground *5ft of 4 gauge KNU OFC power *5ft of 4 gauge KNU OFC ground *Tsunami main fuse holder up front and distribution fuse box for back. *Kicker ground block *KNU 10 gauge speaker wire for sub, 16 gauge for speakers RF rca's, etc 2 Optima Red tops *Monster Cable...

I may even replace the front Alpines and put in a 6.5in component set with a sealed pod to help with that. I can say that the upper range is very clear, crisp and as loud as you want with the 4.150 running it. I have made some great progress and have had a couple late nights. Amp rack is done and will try and carpet it tonight, most of the wiring is done, tweeters are mounted and upper range speakers are wired and sound great. I plan on building the box this weekend then maybe next week laying vinyl or leather on it and testing sub out. The box plan I will post more pictures of progress tonight.

Sounds like he screwed up, If you have that sub firing up at the back glass in a halfway decent box it would hit hard. Much less a FI recommended ported setup. Something sounds wrong

I am done with it for now. I will add the leather arm pad when I get time. I simply cannot say enough about this sub, I am very pleased. I will try and post some vids at some point.

Thanks I did the cooling option and the spider option. There is no BP option anymore it justs comes that way on the new ones. BTW, I turned the freq cutoff up to around 80 or so and stuck Mudvayne in there and it rocks.

3.5 cubes is small for a ported 15? ): Mine is in 3.6 cubes ported and it destroys the low notes but is tuned to do so! I thought you said u had 3.5 before port area and displacement? That will leave you with 2.8 or maybe alittle more if you do a slot port. Its on the lower side but should be plenty to do what you want. Just be aware of what you tune it to. Too high and you will lose low end, tune too low and you will lose the punchy higher notes that you said you like. That why I said go sealed. I had had 3 different sealed setups and they all sounded good with alot of output. 2 of those were trunk cars. Just ask FI what they recommend and they will lead you in the right direction.

If you want it to play 30-80 with decent output I would still do a sealed setup. The Q15 will have plenty of output on 1k. I have mine ported and tuned low, but I could care less about 50+hz being very loud. At 50hz mine sounds very clear and has decent output, but at -40 is where mine starts to shine. Nick would tell you best though

I would not be hard at all to do what Ram said. Unless you sell it I would give that a try and recarpet.

Awesome, I wanna see pics

My opinion would be to go sealed then. Sounds like you want a strong midbass as well. If you want a decent output from 20-200hz I wouldnt even consider a ported setup. Thats a huge range.

I do have room for a second baffle but I am gonna wait on that to make sure the current screws hold the sub in place. I want to be able to add a second baffle later just so I can use longer hardware if I had to. Thanks it turnout better that I thought it would and the sub is just amazing!

Shit is banging!

Just need to wrap it now

I personally would much rather have one 15 then multiple 8's. But in the end its all up to what you want.

I have a beltronics radar / voltage meter in dash and it is staying between 13.5-14.2 with it playing but again it doesnt seem like I am really putting much to it just by sub excursion. I will try and play with the gain settings, I just didnt know if it was ok to go full tilt with it the first day which is basically what I will have to do in order to do it by ear. Thanks!

All I can say is Holy Shit! This is the best sounding sub I have heard. It destroys the low notes and is super clean. Dont have any updated pics but curiosity killed me and I had to put the sub in and test fit the box. The measurements were perfect! I feel like I am not really even pushing it though. Gain is set about 35% and with the remote knob all the way up I can tell it will take more to it easily. Would it be ok to have the gain about 1/2 way up? I will leave it the way it is for a few days before messing with it. and see how it loosens up. I am very pleased with how this turned out!!

Thanks guys I am thinking maybe filling, sanding and doing it in a gloss black lacquer finish, then just wrapping a 1/2in board in leather on top. I have the stock pad but it is awfully narrow compared to this beast.

I have breifly looked but can some please tell me how to wire my saz1500 v2 to my FI 2ohm sub for a 1ohm load. Also does it matter which way the rca's are in? (They are not colored red and white on the amp) Pics would be awesome. I know these may be dumb questions but its the last thing for me to do.

Thanks so just do positive from one side and negative from the other side on the amp? Also what does the "phase" 0-180 do and where do I want that set at?

Box is done, All I have to do now is figure if I want to carpet or try leather/vinyl. I'm too tired to hook it up and get it in the truck tonight so I will have to wait till tomorrow to hear it. This will be my first ported box. I have always had sealed. I have about 16hrs in this box. I know that may sound like a lot to yall experienced people but I wantet to try and do it right. Anyway here are the pics. Bracing Test fitting sub I know one thing, this SOB is stout

Thanks, 3.55-3.60cu after all displacement and bracing tuned to 29hz.

My friend let me use his small wood shop Some good cuts made piecing together, fits good straight cuts This is a bad mofo starting on bottom first now top using Locktite wood glue and 1 5/8 screws every 4-5inches or so, then sealing the deal with liquid nails deck glue/sealant. 1 inch dowel bracing, top to bottom and side to side Only thing left is to put top on and round over the outside edges, Inside has heavy sealant smoothing out the corners. I am really happy how its turning out seeing that I designed and built the thing and havent done anything like this in years! I cant decide if I want a double baffle on front, doesnt need one for strength but may use it for added screw length and hold with the sub in place. Depends on clearance in truck, I may leave it alone. Now I just hope it sounds good.
