SPL & SQ / Fabrication

Hey everyone! I'm looking to replace my current set-up with something new. My amp just died today on the way home from work and so I'm in the need of a replacement. Currently I have a set of RS65.2's up front only, after pulling out the rear deck speakers. Having only a front sound stage is new to me but, after running it a few weeks, I got used to it and really enjoy it. What I'm looking for is either a new amp to power the existing set I already have (not sure how much life is left in them) or get a new amp and a set of components to match. Budget is ~500 but I wouldn't mind going a little more if I could get a nice eq in there to really dial in the system. If you need …

I drive an Olds Bravada (basically a blazer) and I drive it daily, but its a weekend warrior for spl. I have an AA Havoc 15, I'm building the box to the SSA Icon enclosure specs, and running it off a MB Quart Discus 1500. Which would sound better/get louder, facing the sub and port up, or sub and port back? If I face the sub up I can actually use some of my cargo area.. but that isn't a big necessity. It is a four door if that matters.

Just trying to figure all of this out. One site says figure your tuning dependant on port length, others say by width and height of port (square inches of port area). So what's the verdict? I have 2 SSA Xcon 18's wanting them in a 6.5 cuft (each) box tuned at 31 hz. Also, what is the difference sound quality and SPL wise between having one large port or a seperate port for each sub?

I am trying to help a friend build a wall in his '05 denali.. He has four 18" FI BLs and he's wanting to keep his second row seats, third row is gone. This system will be used for USACI SB4 and daily use to please the crowd.. Any help with a design or anything will be appreciated!

I will be soon upgrading my current sub and box setup in my F250. I am limited on space and think I can go 1.5cu without much issue or maybe even up to 2.cu if I add an extension piece. My goal here louder deeper harder hitting setup. Here is a pic of the space I can work with and my current box. 1 10in Fosgate p2 in .53 sealed. I can easily double the size of the current box or I can make almost like a L shaped box to utilize the lower section behind the pass side. Without using the the lower pass side I think I could do one that is (17in H.. 33in W.... 5in D1.....8in D2) this would be outside diameter and I will be using 3/4 MDF. This should be about perfect for o…

*hint hint My buddy is looking to build a center console box for an IA Lethal Injection 15. Looking at 3.5 cu ft ~50 inches of port and tuned to 32 Hz. Looking for suggestions and possible cut sheet. Going into a single cab dodge. From the back wall to as far forward as possible without losing cup holder is 48", between the seats is 14.75" and we're hoping to stay as low as possible for a custom arm-rest. Is this possible? How should he mount the sub? Trying to get as much SPL as he can for daily music listening. Driver displacement is 0.15 cu ft. I'd appreciate the help guys.

The magic numbers for the DCON 10 seems to be 1.25 cu ft, tuned to 32hz. Does the vehicle really have any significant play on that? I don't compete or anything. I just hear this thing really performs with little power. I've got all the components of my budget system except the sub and box. For some reason it's the hardest thing for me to decide on. I really wanted to get away with a prefab box, but they are all tuned around 38hz. What's the point of buying a decent sub if you're not going to maximize it's potential? Anyway, As far as box building goes are there any walkthroughs or step by step type guides? I can figure out all the dimensions and cuts but the assem…

ok, so i have the dimensions for everything, but i want to make sure if its all good, also if someone could do a sketch of it? 2 - 15" nightshades 1 saz-3500D 99 s10 ext cab subs forward, port in the middle firing up but along the back wall of the box. box height - 27 depth - 14.5 Length - 46.5 Port height - 6 width - 16 length - 26.25 net air space 6.68ft3. port area 96.00 in2. @32.19

Where should i put the port? This is going to be in a blazer, and if back how much room should I leave between the port and tailgate?

Hello, I have a 15" Icon sub in a (about) 4 ft3 enclosure, tuned to 30something. The port is just a 6" round PVC tube. I know I have not enough port area. It sounds good But, with the same total volume, would it be better to make an enclosure with the kind of port I can see in all the pics here ? I don't remember the name, sorry! I want to get the best of my sub. (I listen to rap, r' n b and reggae, and I have a saz 1000 amplifier).

I am starting a new kerfed enclosure for two Pioneer ts-w3002d4 subs. I am a little unsure of how to calculate the volume of the kerfed or flared port. I have two designs so far but I am unsure of which will be the best. I am gonna do two separate boxes and attach them together. Which is better?

i'm planning on running 2 orion hcca 12's and the box i'm planning on housing them in aimed at 30hz. it's dimensions are 39" wide, 14.5" in height, and 32" in depth. my port measures 13" wide, 8" in height, and 27 3/4" in depth. will these measurements yeild my 30hz goal. i'm not that good with measuring volume and everything so a little assistance will be greatly appreciated.

The dimensions are" 20" Wide x 18" Tall x 15" Deep = 3.125 ft^3 external Internal = 2.385 ft^3 - .15 (speaker) = 2.235 ft ^3 to work with minus whatever port area??? a little area in the back lost to the plexi window that will be put in, but negligible The speaker is a Fi BL 12, with flatwind and pchamfer options. Tuning is suggested to be 32 hz and box size between 1.8-2.5 ft^3 I can't go much bigger due to trunk opening, and for that reason I am building to boxes of the same size and putting them in the trunk that way. I mainly listen to Rap/ Hip Hop and Hanna Montana ( ) These will be facing towards the seat so that the plexi rear is visible when opening the trunk. I …

Ok guys, I'm gonna need some help with an enclosure. First, some background. I have a friend who everyone had him talked into buying the usual kicker stuff, but luckily I got to him in time. This will be his first setup. Anyways, I coached him through buying an AQ2200D (could have chosen a better amp, I know, but his budget was sort of limited and we didn't feel like going through the hassle of looking for used deals on others), an 18" DC Lv5, and all the other bits. Should all be getting here by the end of this week. Alright now to the enclosure: The vehicle is a 2005 Tahoe Z71 (captain chairs in the rear). Now I measured awhile back, but if I remembered right, it should…

what is a good primer for mdf boxes a link would be very helpful thanks

I am trying to come up with a good design for a ported box for a 18" BTL. Now it is going to be in my trunk but I am going to try to get a full 8 cubic feet. It can be 41" wide, 29 inches deep, and the tallest it can be is 18.5" and that is exactly right size for a 18" BTL. The only problem I have had is that I know it is going to need some kind of bracing and since I have no idea how to go about that I don't know how to calculate in the displacement of the extra bracing, and I don't know how to figuire out how big I will have to make my port to be at about 30hz. If it is under 8 which I'm sure it probably will be I'm fine with that I guess, but I need some help on how to…

Okay. So I've got very limited trunk space. And a small-ish. Budget. I'm hoping for someone to help me with some sort of box design for an FI Q 10, in a ported box. Max dimensions being 30" Wide, 14" High, and 17" Deep. Already have an Amp picked out too that i'm gonna buy from a buddy for good.

I currently have 2 15 fi Q's and want to put them into a fiberglass enclosure. I will frame the back, bottom, and both sides out of MDF, but i am wanting the top and front of the enclosure to be fiberglass. What is the recommended thickness or number of layers of mat or cloth that i should apply for 2 Q 15's. Amp using the AQ 2200D amp if that helps. Thanks

alright so i think im going to be mounting my future amp to the back of a seat. is that bad? and also what material is good so the amp doesn't rattle around.

OK I'm finally going to begin my build next week sometime. The box will be a center console going from the dash to the back seat with 4 12" RL-p's facing up. My question is should I have the port firing forward towards the dash? Or firing back under the rear seat? This setup is going in an '05 Chevy crew cab. Thx for any help.

To have a loud LOW end and the SMOOTHEST transient response (not punchy) and DEEP overall which type of box should I get.

im doing a wall in my hatch back i will be doing bass race bass boxing and meca driveby but how will the best way to place the port drivers side? top?bottom? any help please oh and ill be using my 2 18"treo ssx subs

looking for some help with the enclosure i am planning to build in the rear seat of my accord. it is not going to be a wall but a ported box reall. i was just wondering how to face the subs and ports. like subs up ports forward and that kinda junk. well i guess i should have stated what im looking for. im looking for a loud daily driver.

Whats the best way to mount an amp on a sub box and not have an issue of the vibrations messing up the internals of the amp?
