SPL & SQ / Fabrication

Hi.. this is my first build so i have little experience right now. Im getting 1 ICON 12 with either an AQ1200 or an AP1500 amp. I drive a 2000 jetta, the trunk is about 40 inches wide. I am not really sure what type of enclosure i need, the specifications for it, or where to get one so any help would be nice.

im headin out to the store tomrrow to get some stuff well im there i wana pic up some new screws that will keep my sub down nice and thight. i did not go with a dubble baffle and with my new 15inch ssd on its way, i wana make sure that my sub does not lift out. here is the thing my last sub a audioq 2.5 was jumping around pretty hard in the same box the ssd is goin in. Can any one lead me to the right screws so i will not have a issue? I will be bolting the box down better to make sure the box it self is not goin no where as well. thanks guys Joe

first thing sorry guys ive tried posting this in the fi section didnt notice it was in the wrong place but im trying to find out the cubic feet on this box and its tunning cause i made it but in order for it to fit i had to chop it down 2 inches if anyone has any ideas or any help it would be great and its for a fi bl 15 and again sorry for the double post

I decided to finally sack up and start planning a blow through. I just can't find anything around the web that actually explains. I really want to use aero ports. Do you think, if I sent two aero ports through the bed, and into the cab, that would be sufficient? I'd like to cut the smallest holes possible. Although I said before that I sacked up, I'm still pretty scared about cutting up my relatively new truck =). So, anyone have personal experience, pictures, or even tutorials? Thanks OH. Before I forget, My goals are to sound good, but have a really nice side of spl on the side. Just a daily ground pounder that sounds good,. I'm still trying to decide on which subs, bu…

I have an old sub box that came with an RE SX15 I bought used. It is 3.1 cu ft net before driver displacement. It has 2-3" aero ports in it. 9" long. I used it before with the sx15 wired at 2 ohms on my saz-1500d. I never heard any port noise, but it didn't sound great. I later built a 4.25 net cu ft box for the RE tuned to 30 hz. It sounds great. Well I think I have a buyer for the RE and was wondering if an SA15 would work in the old box. It's about the right volume and tuning would be right about 35hz(recommended) but it's seriously low on port volume. I was also thinking I could put a third port in it for burps and bump tuning from 35-45hz. Not to mention increasing …

Alright, so iv been looking at the inside of my car lately and it makes me a bit sad. My car is black on the outside, with a 2 tone grey interior and wood trim pieces. What i was thinking is to get a bit creative and change up the looks of my interior. I wont be upholstering or anything, i was just thinking about taking off some of the pieces and painting them black... Not sure yet... Give me your opinion if youve ever done something like this. Heres a few pictures so you can see what im working with.

Just starting to get really into car audio...Bought the Fi BL 18 last year and put it in a 4.0 cubic ft box running around 1100 RMS (i know its a small box, but its in a trunk).. haven't driven in over year, but about to start back up. My question is what makes the bass sound so different.. I mean my friend had 2 12's in a smaller box and his just sounds so clean and clear, while it sounds crisp inside, on the outside the car it really isn't banging like it is in the inside. My set up however just sounded mean and powerful inside the car and fairly loud on the outside..I've heard the terms (clean bass) and (dirty bass) before, but I'm not exactly sure what is meant by t…

Long story short my friend built my box and it turned out horrible it wasent his fault he did not have enough tools or supplies but I'm getting a shop to build me a new one and I have an original design but its to wide but I can add to the height my dimensions are 22 deep 33 high 55 wide the box design is 27 high 27 deep and 54 wide wouldn't the volume even out if I went 32 high and 22 deep?

I'm currently building an enclosure for 1 Fi BL, (15") and I was wondering, which box will better suit the sub, (both will be tuned to 32Hz). 4cuft 4.9cuft See signature for car and current setup info. Thanks

Let me start off with the basics. I have an '01 Accord and I'm looking to do at least 140 on music, but the louder the better, but I want it to sound pretty good still. So, in the works is possibly a 5200, whether it will be a 15 or 18, I don't know, thats why I'm comin to you guys. I have a 170A alt, Odyssey 1200 under the hood and 2150 in the trunk. I have an RF T30001 for my amp. I'll be able to do either a 15 or 18 ported (the 18 requires 5 cubes after all displacement). THis works great for me since I fit in an enclosure that was 5.5 cubes after displacement. Whether a 15 or 18, it will fire up due to height restrictions. I'm just wanting to know what will be the di…

when building kick panels for 6.5 comps would it be better to leave it sealed or to cut a hole and vent them into the inner fender. what is the sound diff in the both. thank you.

I'm gonna be helping a friend build a box for 2 cvr 15's. It will be in the trunk of a 4 door saturn ported through the rear deck. I haven't played with cvr's much so im not too sure how to get the most out of them. Space is limited so i was thinking maybe 7 cubes with 112" of port tuned around 50. Starting it this weekend and could really use some help. Anybody have experience with these subs in different boxes?

Hey everyone, Long time lurker here, finally decided to pull the trigger on a 12" ICON and would like recommendations for an enclosure. Given my driver choice I'm obviously going for sound quality. But who doesn't like a little bit of output? It will be going in an IS300 and run off of a PDX M12. My ICON will be seeing anywhere from 500-1k watts depending on where it blends best with my front stage. Anyway, I noticed that on the product information page for the ICON there are two different optimum enclosure size recommendations. Under the "Enclosure Recommendations" tab it lists ported optimal as 2.25 ft^3 @29-34hz whereas the "Pre-Designed Enclosures" tab has a l…

Do any of you know what software 'HexiBase' is using to make his enclosures? https://www.youtube.com/watch?v=5VFx37kz5Ww It would be awesome to have a bit of a play around with it to see how my current system stacks up. Thanks in advance

I have a beautiful box that was built specifically for my vehicle. Now im going a different direction with my setup and I want to lower the tune on the enclosure. I have done a little research and I know that decreasing the port width will lower the tune of my enclosure but i will have to sacrifice a little port area to do so. What are the pros and cons of doing this? By the way the enclosure is tuned to 35 hz and i would like to change it to about 30 or 31. I currently have 100 in squared port area.

Basically those bars connect the hinges from the left and right of trunk lid. They are bent in that way to accommodate the 6x9 speakers. I am going to remove the speakers this week. Could I replace them with some straight bar???

ALright so i want to do a kerfed port on my next box... i read a thread and i am almost ready to give it a shot. However i have one question. when you do the kerf, do you use the port piece to kerf and then attach it to the front piece on the box or is the port piece and front piece one seemless piece with the kerf in it? if this doesnt make sence i will try to expalin better.

Ok basically I had an ok box, performed well'ish, ported 2.4ft3 60sq" port @ 33hz, then I made an adaptor to sit over the front and channel the ported box into the cabin via the skii port. This worked a treat and made it much cleaner sounding and changed my tuning down to 27hz. Now, I have a new box finished I payed some $$ for and its 2.8ft3 tuned to 32hz with 50" inch of port, the concern is pretty much straight away below 32hz the sub seems to sort of get stuck in and doesnt excurt properly and have stuff all output also, what is this and what can cause it?? I know it could be a lack of backpressure in the box but the new box I thought was a much better design than m…

Originally I thought my enclosure specs were very close to these, tuning and volume wise: 42W" x 22H" x 22D" - outer dimensions= 9.84961ft3 gross volume 7.3ft3 net volume tuned to 32Hz 6W" x 20.5H" for 123in2 of port area port 1-14.5" + port 2- 7" = 21.5" port length After reading through Chops end correction thread, Ive decided to do the math myself and find out what Ive really got. This is what Ive come up with. Im way off... The port length is actually 27.5". I had no idea how to measure the port. The tuning is more like 30.3Hz port volume calculation: 6W" x 20.5H"=123in2 123in2 x 27.5"=3382.5in2 3382.5in2/1728in2= 1.96ft3 of port volume 9.84961ft3-1.96ft3(port volume…

i have been working on not using the stupid ass re calc and doing everything on my own. how does this look. height 16 width 30 depth 20 with a 4 inch wide port 33.80839511415706 inches long tuned to 32 hz.

Subs:2, Sundown Audio E-12 v1, 400rms Amp: Hifonics 1700.1 wired to 1 ohm (so 850rms per sub) Box. Custom mustang vert box, .9 cubes per sub sealed. Right now the E-12s are reversed mounted to get the most usable airspace. Is there a subwoofer that would better handle the power such as the soundqubed HDS 200 or 300. Also, should I stuff the box with polyfill or something? I can't turn my volume up to even half on some songs before the subs start to distort or bottom out. So what can I do to improve my setup?

I was bored so I went & picked up 2 12s from a flea market this past weekend to experiment with. Made my first box throughout this week & tuned it to 32hz. If I wanted to tune it to 30hz would I add or cut off some wood to the end of the ports behind the subs? I can do the math but need a starting point. Also another separate question, would more port area equal a lower tuning or does it depend on the box?

looking around for some round tubing to fit an 18 inch sub, i had seen someone who has done this befor on the Mach 5 Audio test bed site but I cant find that site any more. If any one has done any thing like this befor tips and how to measure air space would be a big help. Thanks.

I was wondering if anyone has done builds on a 97-00 Honda crv and how much space I should leave between the box and hatch?
