SPL & SQ / Fabrication

Well, It's been a while since I've been on here. Graduated college and disappeared from the scene to start a career, which lead me to 3 states in 3 years. Finally got a vehicle I've always wanted: an SUV! Picked up an Alpine MRX-M100 on Craigslist for $50, and just bought a new Fi Alpha v2 15 yesterday (hopefully that comes in before the new year). Definitely won't be as heavily involved in the SPL scene as I was years ago, but I think I might just make something to have some fun with at a couple of competitions next summer. Here is my plan so far, and I would like input/feedback for anyone that has worked with a Renegade before: 800-900 wrms realisticall…

I have made a ported box just over 1 cubic foot. This is for a 400rms, 10 inch sub. For a 2.5 inch wide pipe, I need 11 inches long for a 32 hz tune. IS IT OKAY TO USE 2 PORTS? and what type of pipe do I get? Can I just run to home depot, find a strong looking 2.5inch wide pipe, and go from there? and are 2 ports okay to use, even if there the same length?

Okay, I will be finished up my box tonight and had a few questions before I close it all up and get it hooked up. *I've seen online that it says to put weatherstripping around the hole for the sub before putting the sub in the box? This true? *And I've seen people use resin on the inside or their boxes to help the structure? This true aswell? Thanks for the help and thanks to everyone that has helped throughout my first build!!

I'm in the process of starting a new install in my '95 Probe. Purchasing a DD 3500 series 15 and RF 1000a2 from a friend. Initially I plan on running the box he was using in his Explorer which is around 5cf. with 3 4" aero ports, can't remember the length. I'd like to build a new box to better fit the Probe, and I'd like to see if I can't get a little more out of the setup in the process. In the Explorer this setup has metered at 147.?db and I'd like to see if I can't manage 150. Any suggestions on box design would be appreciated. I'd like to keep it tuned low ~30-32hz.

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.

We are having a meca sponsered show, and should be a blast , there was about 50 cars here last time, and everyone had a blast. if you have any questions feel free to call us at 269-426-0009 ask for kyle here is the link to the flyer for the show. http://www.mecacaraudio.com/flyers/5-20-07MIv2.pdf

i have a 12" FI Q w/ BP option in a 2001 jeep grand cherokee. powered by a SAE 1000D @ 1ohm. right now it's in a 1.5cuft (external before displacements) enclosure that i had the (horribly stupid) local audio shop make for me. i was short on time. i'll let you know dimensions of the room i have to work with. but there is basically as much room as you could ever need for a single 12. or i want it ported tuned to anywhere close to 32hz. so yea, have fun, keep in mind this is my first box. and i don't want it to be over (i believe) 16 inches. i just want it to stay below my rear window level. thank you so much i know it's not really hard. it's just a temp box to get some prac…

Hey guys I made this box for 2 audioque 12 hdc3 subs and i want to know if this is an optimal design and if you guys have better ideas give me dimensions i want 36-37 hz thanks guys heres my design the slot port is going to be the bottom so the height is actually the width

okay these dimenions that i have for this sub box say the front and the top are the same okay thats where i get confused with it because i thought the top was the top of the sub box and the front where the ports at is the front not the other way around. 2cubes35hz2925sqin6tn.png i hope that the picture worked because i do not know how to put them on here if it doesn't work just tell me. because this is really confusing me really really bad.....

What has been your favorite show you have attended, not necessarily competed in? I would say the best show (besides SBN) would be the first show at Ft. Drum, NY back in July of '00. It was a smaller IASCA show hosted by Terry Floyd. There were maybe 25 or so SPL cars and about 10 or so SQ cars. I met a lot of people at that show that wound up being good friends. Highlights from the show. I had the high SPL for the day at 151.0 I caught my car on fire! 2 of my other buddy;s got 1st in their respected SQ classes Here is a buddy's truck that won one of the pro classes. He went on to IASCA Finals that year. Real sweet truck.

I'm going to be purchasing a table saw in the near future. My question is: how big do I need? The only local place to buy MDF in my area only sells in 4x8 sheets, so I'd have rinse this saw with that initially. I found a nice looking one at lowes for $150. It's a 10". I don't know what the 10 inches refers to.. Would that be big enough to get the job done on a 4x8 sheet of MDF? If not, what about 4x4? I think lowes can cut the sheets in half for me.

New to car audio here. I recently purchased a SoundQubed HDS312 and SoundQubed Q1-1200.2 amp and plan on building my own box. It will be wired to 1ohm and installed in a 2006 Trailblazer. My question has to do with port firing direction, this is a work truck constantly filled with tools and I would like the sub to be facing up so it doesn't get damaged, and have the port facing the rear or both facing up. I've created two boxes both 2.49 cubic feet at 33.48hz: Any input would be greatly appreciated.

I am doing box plans for free (technically). All that I request you do is sign up for my free ipod link and do an offer. I do everything by hand and I will design a rough outline, cut sheet, and assembly instructions for you. Think of it as trading my time for your time. You can do that offer for free by going through the ancestry.com site.

The guys at kicker said to tune to 39hz for 4x12" CVR's in a 9sq foot box. I don't see many people tuning much higher than 35hz though. So should I take their word for it and tune for 39hz or drop down to 35? This is my first ported box so, I'm somewhat at a loss.

I'm going to be building a box for my friends Ram. Aero ports seem to be the only way to port this box but I've never used them before so im looking for a little help. Box will be going under the rear seat. The sub is a JL 10v3v3 Box will be about 1.33ft after sub displacement Tricky thing is I only have about 3 inches of height for the areo.(Rectangle box with wells on the bottom) The Rectangle part of the box will be W54.5-D13.5-H3 JL Recommends 32Hz 84.7 Slot Port Area

im looking a good online site to buy some epoxy resin along with some 4 or 5 inch wide 18oz.(or so) cloth tape...anyone know of any good sites?

What are the advantages and downfalls of fabricating the vehicle below for a SPL vehicle. http://www.we-todd-did-racing.com/browse/g...oud/51586_mp6d9 Playing with the idea and would like some feedback. Much appreciated.

alright guys i was just wondering if someone could either link me to or explain the pro's / con's of tuning higher and tuning lower? and how to figure out how enclosures should be tuned in regards to diff subs and scenarios? thanks for any help guys! (i ask because im not new to building enclosers, ported/tuned, just want to understand the tuning aspect better because i plan on building some enclosures locally for some friends and friends of friends - just want to make sure i make the best enclosures that i can...i need the extra money..lol)

4 Sundown Sa 15 W 36 In H 20 In D 40 In Port Width 20 In Port Height 9 In Tuned 32hz Sub Up Port Back Max Dimensions Are H 33 D 54 W 38 It's Going Into A Scion Xb 2008. This Is My First Shot At Designing a Box So Any Helpful Input Will Be Appreciated.

Anyone know of which programs professional fabricators use...?

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.

today is a little local show..nothing big, again sponsored by stereo one (yay )...so i'm going up to see what i do on a audiocontrol mic let ya know later!! wheeeeeeeeeeeeeeeeeeeeee

I have a DC XL m1 18 that i am wanting to put in my truck (02 Silverado 1500HD). I am thinking about taking the 60 part of my 60/40 back seat and making a box above my amp rack. I am wanting to tune to 30 hz or lower and would like to possibly do a hairtrick. Is it possible to do in my truck with a single 18? Here is what I have right now: 1 DC XL m1 18 D2 1 Crescendo BC2000D 1 Mechman 270 amp alternator 1 Stinger SPP1500D battery under the hood All 1/0 for big 3 and running to amp This is a box I come up with Would I need more port? Should I change anything else? And where should I place the port? the sub will either be facing up or forward. Should the port face forward…

im looking at my max dimensions and it looks like its going to be around 8 cubes and its most likely going to be tuned to 33hertz and i was wondering if thats too big? its a shared chamber subs and port up(going in a pickup)

I was messin around and just seein where the power wire would go through, and i realized that the firewall already in use for the factory wires was pretty much full, and i don't see how 1/0 is going to squeeze in there. But a couple inches to the right and one or two inches above it, theres what i'm guessing is an unused firewall hole. Its a rubber surround with a rubber filling. I tried to see where it came out on the engine side, and i couldn't find it. Does anyone know if i could (once i find the hole, as it was a little dark when i did this) puncture the rubber filling and take it through there? If not, what should i do?
