SPL & SQ / Fabrication

Hey everyone, been a member here ever since I bought my saz1500D last summer, and I Love it! been running it at 2 ohms to a pair of the older type r 12's in a sealed box since then. Around the time I bought the amp I got 2 of the new R 12's and now its come time to try and build a box for them, this is the first box I'll ever attempt so I dont really know how to get proper dimensions, ive tried the re calculator, but im still unsure if im right....so I figured I'd ask. but anyway vehicle is 98 gmc jimmy so space isnt a huge factor if need be, i can take some measurments of max size subs Type R 12 dual 4's x2 amp sundown saz1500D@ 1 ohm I'd like to have subs firing up slot…

Hey guys, I have been talking to a member on here about some calculations I used from BCAE1.com, and something just isnt adding up right.. here is a pic of the box I HAD DESIGNED by a member, so I trust this will work, but I just wanted to enter in the info on BCAE1 to see if they would give me about the same specs.. NOPE....>>>>>>>> This is the box I want to build... but when I put the specs into the BCAE1 site... it tells me to build a 1.3" port... what am I doing wrong here with this program????????? Height? =15 Inches Width? = 39.5 Inches Depth1? =26.5 Inches Depth2? = 26.5 Inches If the above dimensions are OUTSIDE dimensio…

i have 3 300amp breakers now... im popin one of them somtimes.. the onw between my amp and my rear cells,.. i know that once thay pop thay pop easyer... i bought a new one on ebay... i was stoned and bought another 300 amp!..... so now im looking for a 350 amp or a 400 amp CIRCUIT BREAKER... any ideas?

just wanted to get some thoughts on bass box 6 pro..is it user friendly for a noob box builder like me and if so does n e one have it avail for a small fee

guys im building a box just for the hell of it..its going to be a sealed box and i just want to see if i can do this because im sick of paying $250+ to have others do it for me..the size of the box will be 2.5 cu.ft..so if you guys can list what i will need to get this done besides nails,hammer,glue, also what kind of glue do you guys like? i really hope i can pull this off...thanx guys

I think i wanna run a buss bar only across the ground terminals of 3 batts in the rear of my vehicle. I can't safely run one for both power and ground if you are wondering. Anyway, the reason why i would want to run one for ground is so i can just run all 3 of my amps ground out to the batt's ground buss bar. This way i can run multi runs of ground wires off of the buss bar, let's say 2 runs of 1/0 off the left and 2 runs of 1/0 off the right. Where exactly do i go to get one and how do i know if it's thick enough... if it'll fit on my batts, etc... they are for kinetiks so i know i can take the posts out of the batt to bolt it back down. I found a site that was selling a…

Whats up guys. I am going to try to build my own box. I have only built like 2 before, but I want to give it another try. I was wondering who can I Pay to design a box for me for 2 15" Type R's... If you are interested, or have worked with these before please let me know, or send me a PM.. Thanks. Steve-o

Getting ready to do a little sound deadening this weekend. This is going into an 07 Altima. Do I need to remove any factory deadener that is glued to the floorboard or any other place. I'm not talking about any jute carpet or material that can be easily removed with my hands. I know that some cars have factory carpet/rubber like padding on the floorboards, does this need to get removed or can I just deaden around it? Thanks. Thanks!!! :drink40:

Anyone know if there are any major/non major SPL competitions in NJ area. I would like to go up and watch and maybe participate in the future. But mostly just watch in awe. Curt

i have a question i have an 1.25 cubic inch pvc tube for 1 15" and i want to tune it to the peak freq. of my car. i dont know what frequency is best for spl in my car i have a 4 door mitsubishi mirage and im going to use aeroport 3" and the woofers are RE XXX thanks in advance im new to this of port is there any advantage using larger aeroports in sealed i measured in the 58 thanks

I was thinking about to the standard square ports, but last night I thought about doing one, maybe two, larger round ports using PVC. Has anyone tried this. I was thinking something like 8" diameter ports, maybe two of them. Since it is going in a blowthrough, is it also okay to extend the ports out a little, maybe almost into the blowthrough to ensure more pressure from the port goes directly into the cabin of the truck.

Here is the low down of what my system consist of Double Din tv with nav kicker ss 5.25" componet set kicker ss 6.5" mid bass zapco 1000.4 4 channel amp 2 zapco 10s cadence a7 ( for now) my a7 or whatever amp i get will be hid where it cant be scene. these pics below will just show the center console where my zapco amp will be. my truck is an 04 f150 extended cab with a center console already, i just made a piece that conformed to the back of my existing console to extend it all the to the rear of the truck. Here is some of the pics i have so far, not done but you get the idea Using cardboard to get the templet from around my cupholders test fitting one of the panels st…

can someone tell me what are the benefits or any of building a kefed box..they look good as hell but is all the extra work really worth it..jus wanted some opinions

what is the better year for spl? I think that they changed body styles in 88 so before or after then. Since I'm looking for another car that's good on gas this would be an option. Just lookin for for suggestions and maybe a tip or to too get them loud. thanks

my question is im trying to make a box for 2 18" btls dimentions are 49"L x 24"T x 27"D here are some rough sketches from paint how should i go about bracing it i know that i need to(or do i?) since im planing on running them on 2 SAZ-3000D and i will doublebaffle the top where the speakers will be mounted would simply corner bracing like in this pic be enuff and also placing a small block of mdf on 1 or both sides of the port to support the middle of the box

due to the complexity of the sides of my box, its going to be kind of hard to build a slot port on the top of the box. i was thinking, instead of a slot port, should i do like 4 6" aero's? (or whatever i need to get the right amount of port area) which leads me to my questions. -if you have 200 (example) sq in of port area, with a slot port, if you switch to aeros, do you still need a ton of aero's to get 200 sq in? or does less aeros equal out to the larger port area of a slot port? -aero ports in a wall. how will this work? i know one con is i dont get the natural bracing a slot port would provide, but ill deal with that, and add some extra bracing. -difference in sound…

im looking if you have some photos of pvc tube with aeroport im looking forward to prove this on my car thanks i have some photos and i wanna see if you have som more for the experiment thanks something like this but i want to put 3 aeroport per pvc tube some smaller aeroport to check if this is better than sealed pvc ohh its for 15 RE XXX

Looking at sub manufacturer recommendations, box sizes for each sub can vary by quite a bit. I'm just curious what the difference is. I know that a larger box decreases power handling of the woofer, but is there any difference in sound? Is a smaller box more susceptible to peaking? Sorry for the newb question - I'm trying to decide what will fit in the trunk. Thanks guys.

First off, i know i already posted this in general car audio, but i just wanted to get as many opinions as possible, and i always seem to more replies in here than anywhere hahah. Sub: Fi BL 18 with flatwind and p chamfer Amp: Hifonics bxi2006d (again, its not sundown or anything, but it should get the job done for now and even if it is overrated, i think 1800 should push a bl just fine. Wiring: Knuconcepts.. look Not included in the kit are RCAs and the speaker wire. Also should i get 10 or 12 gauage, and what do i need to fit it into the terminal on the sub? Enclosure: 6^3ft after all displacement and port, and tuned to 34.4xxx hz. I guess what i'm looking for is the O…

I am planning a box design in which I am using two 3" aero ports. The ports are supposed to be 7 inches long. My question is when using aero ports does the actual tube have to be seven inches or does the entire port assembly (flares included) need to be 7 inches?

I am building my first box for my 4 aa's ported to around 25-28 hertz and about .75 cubes per chamber any tips its going in a 1994 gmc serria reg cab.

This is going to sound awfully newbish, because...well it is. I see all over this forum and various others about what to tune a ported box to. Well it dawned on me a while back, what does it mean if you tune a box to, ah lets say 32 hz? Does that mean that the subwoofer can only play notes above this frequency, or what? Also what particular specification(s) point you in the right direction on what to tune the enclosure to (besides the obvious manufacturer's recommended boxes, as I see a lot of people that don't necessarily stick to what the company provides.) Please go easy on me, as I am really clueless when it comes to ported enclosures (as I personally like sealed …

What is everyones definition of Sound Quality?

Knuconceptz 'Knucar' This guy might have an ssa membership, idk, but has anyone seen this? Everyone says 45 degree angles help airflow, so what would a perfectly round one do? It'd be near impossible to tune if you wanted to port, but if you could, would it actually work? Trust me, i'm not thinking of doing this because i can't make a sphere out of play-dough, just curiousity here.

Just letting you local guys know April 12 is the crutchfield show in Harrisonburg Va. and there will be another show the next day in Charlottsville Va, both are 2x MECA shows. Ragnaroksq and I will be making the trip. any other SQ guys going?
