SPL & SQ / Fabrication

In my progression to finish my build, some of my amps may require amp inserts for dual cables per input. Now, i have the tools here to make it, that's easy. The thing i do NOT like about these inserts is how they are secured in the amp.. just by the little set screw on the amp.. For holding a solid piece, i fear the insert can "turn" eventually and i don't like that. Instead, i thought about purchasing a Metric tap and die set to tap the power and ground inserts on the amps. There appears to be enough metal in there to do so easily. I do not know 100% what size tap i need but i got some micrometers here to find out but the question is this- If i tap the amp and die the i…

How do you guys carpet your boxes? I am going to be carpeting on saturday and was wondering what you guys think is the best/easiest way to do it.

I'm going to be putting together a new box this weekend for a 10'' BL in my reg cab ranger. First off, the box will be 1.6@36-37 with (2) 3'' aeroports (Fi recommends 1.25). Will I run into any problems with having the box larger than optimal size? How should I put my ports? Here's the space I'm working with: Option 1: Option 2: Option 3:

OK, so I've decided to try out a box using round ports for my 18" nightshade, so i can make the ports interchangeable for comps and daily. I'm using a Hifonics Brutus 1600d amp. i figure the box should be about 5 cubes since the amp isn't that powerful and i want to get a lot of output. i want to use 2 6" diameter pieces of PVC. i am going to do some testing to figure out where my port should be tuned at for spl, but my question is that if i want to keep the box at 5 cubes how big should i make it to make sure its still 5 cubes after the displacement of the ports? i have been looking all night trying to figure this out. i found that if my box is 5 cubes i should use 2 6" …

Ok, well My trunk openings are garbage, my trunk is HUGE but, I can't get a box inside the trunk from the rear or from the back seats. So, my only 2 solutions are this. 1.) I lay down plastic so I don't get anything in the back of my car, And I pre-drill the screw holes and put the box together while it is in the trunk. Only problem i see with this really, is the internal piece for the slotted port. 2.) I build the box split down the center, having a top half and a bottom half, which would be Biscuit jointed or using dowels and thenglued together in the trunk, and then over the joint external strips would be screwed into place to hold the joint together. Both of these are…

What makes this enclosure perform any better than a normal forth order enclosure? Or this old style. Just a forth order bandpass?

My boy is about to buy a 04 monte carlo. He wants something loud in there without sacrificing the trunk to much, I wont have any measurements for a few days but I wasnt sure if anyone has built anything in one these and mite know some ideas for speaker and amp brands

What do you guys think of this design? The huge ported section will be roughly 50 width, 36 Height, and 36 length all the way up to the back of my front seats. The sealed section in the trunk will have roughly 1.5-2 cubes per sub with the ported having over 30 cubes hopefully Give me your opinions of this design please Thanks http://img573.imageshack.us/img573/9628/boxdesign3.png http://img341.imageshack.us/img341/570/boxdesign.png http://img29.imageshack.us/img29/7765/boxdesign2.png does that make sense?

I wanted to paint my port chrome and layer it in plexi. What would provide me with the greatest reflectivity as far as spray paint goes? I looked into mirror finish film but it seems to be quite pricy. I wanted to spend around 50 dollars max for about 25 sq ft.

hey, i am familiar with both ported and sealed boxes. but im not sure what is better, i know that ported boxes hit cleaner and i know ported you will have more spl. but i heard that with ported you get cone distoration and the sub hits sloppier. im just wondering what your specs are? thanks

ok i have a 2002 dodge dakota extended cab, and i was thinking of putting 4 SA-8's in the back area after taking out the back seat. i will get the D4 coil configuration and run 2 off a dsc1000.1 and the other 2 off another dsc1000.1 (each sub will get 500watts) now i have no clue how to design a box, the only other ported box i made someone else designed for me and i built it. i dunno max dimensions of the box but if you tell me how many cubes it has to be i can figure out how to make that size box fit where it needs to, also for the "easy" factor id like to use aero ports instead of a slot port design, so what size and lengh aeros would i need? and where can i buy thos…

This is kind of how I want my box we will be adding some surprised but this is the basics of it. Ok for the car audio techs. What is the specs to make this port tuned at 30hz-35hz L ( ) W ( ) H ( ) I know my installer will know, but I just want to find out for myself. Oh yeah could you also let me know how you got your answer I want to learn as I go.

Im Helping a friend design a box he kinda wants a half wall. Two subs inside the cab ( no rear seat) and two in the trunk area. My idea is 3.5 cubic feet per sub about 55 cubic inches of port per sub. It will b one big box but inside it will be like each speaker has its own box and they all have their own port. So i suppose 14 cub ft internal after sub and port displacement and overall about 220 cub inches of port how does that sound any advice is appreciated. He has none of the equipment yet but he wants 4 cvr 15s and for power either two kicker kx1200.1 or one zx or kx 2500.1?

I got 4th in 139.9 after busting out against alpine. But I got to take Bill out in round 1 so that made my day 1-6th place finishers in 139.9 all qualified with a perfect score My scores for the day, 145.0 windows up 145.8 windows down 146.6 drivers down All on music (jeezy, ~40hz) Thanks DC for making a lvl 4 strong enough to hold 2800w rms -Derw

Was wondering if anyone on here could offer me a reaonable design for a btl 18 for free. I have a guy at the car audio forums that has always done mine for a small fee (they are reasonable). BTL 18 Tuned to ~30 hz. ~ 5-6 feet ^3 48 inches wide... and max of 24 inches high.

Im tired of my setup so i sold my 4 15's but now im stuck with the box..so im really looking for some advice on how much should i sell my box for.. Specs: 4 15's, 15ft^3 tuned to 35hz via a 45"x4.5" port. The overall dimensions are 48" wide x 25" tall x 34" deep. The entire thing is double layered, except for the bottom..its bare mdf on the outside but the whole inside is coated in fiberglass resin.. http://i1223.photobucket.com/albums/dd509/Elrey7698/de7c216c.jpg http://i1223.photobucket.com/albums/dd509/Elrey7698/fe895540.jpg http://i1223.photobucket.com/albums/dd509/Elrey7698/abd78364.jpg

i have a 96 s10 reg cab and in order to have a bigger system im forced to build a blow-thru. ive decided that my best option is to do a 4th order bandpass with the port coming through the back of my cab. i like the idea of having a single octo-port (just because i think they look effin b-a). ive done read just about everything you can find on the net and also talked to a few guys who have them....but everyone says something different....my question is how do you tune these things??? "golden ratio/theory"??? i plan on using 4 Lanzar Max Pro 15's (yes i know what your thinking) but they dont need a ton of space and power

I'm having my enclosure built for an Fi BL 15 that I'm ordering. Im getting the enclosure 3.5 cubic feet. Ported of course. And tuning at 35 hertz. I listen to mostly bass songs. though i do like listening to my spanish too. Bass rap/hip hop music like Young Jeezy, Gucci, Lil Wayne, and so on. Its going in my Altima trunk. Please give me some input, shed some light. Thanks all.

hey guys, im purchasing 2 12" Fi ssd Im looking at a ported box, I was just wondering if i need the divider in the middle of the box giving them their own little chamber? or can i just make one bigger port rather than 2 smaller ones ? also aeroport? Is it worth the try ?

Im about to do a build for someone and wanting help with the enclosure design. They are wanting a c pillar wall with port across the top. Its for one 21" warden on a sundown 4500. High output alt.

ok so i believe my sub box is about 1.08 cuft or very close to that. if i was to add this kit here... http://www.madisound...products_id=711 you think that would fit my application? in order to get 34hz with a single 3" inlet im going to need a "13.06364" long tube. if i got this kit i could cut it to length? what do you think? with a box of that amount of cuft do you guys think i should tune to a different setting aswell? let me know what you think!!

alright so im building a box for 2 15" LI's. the box would be 33" in depth which gives me 3 inches from the hatch on my jimmy. i think i read on here somewhere that there should be a least 6 inches for it to load off whatever the ports facing. the subs would be on top and port on bottom.

When building a box inside the trunk whats the best way to start? im getting a box pre designed with all the cuts i just need to assemble the box inside the trunk

I want to start this off early....give me some ideas on how to make it better.....Chad^2 don't even mention payment....the next time I see you I will pay you personally......start from the bottom guys....food?....music?.....type of judging??? I want to hear it all....

this is kind of a silly question, but im in need of a little help. im starting my box tomorrow for my FI BL 15" and curious what kind of screws and glue i will need... OR any other materials i should get together. the box should be just under a 4 cu ft. i picked up a huge sheet of MDF today. just felt like asking you guys what you would recommend before i buy. THANKS!!
