SPL & SQ / Fabrication

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.

I am doing (2) Sundown Sa 8v2's on a Cresendo B2000. The box is going to be a little over 1 Cubic foot and am looking to do an aero port. I want the tuning to be around 30-33hz and need to know how i would calculate the dimensions for the port. PLEASE HELP!!!!!!!!!!

1st run 150.7db 2nd run 150.1db charge batterys a few min. 3rd rub 151db got 1st place

not sure if this is the right spot but anyways any of you guys try to fit 1 or 2 of these under the seat of a pick up before? the truck actually is a 2006 F 150 super cab.....dont get it confused with a super crew. Im gonna try and figure out the box today and i just thought of using these i was going to run two 8's ported off 1 SAZ 1500D. im also considering two RE 8's too but i figured the AA would handle the power better than the RE's. Anways the other question i have is how much room is good to have between the cone and the floor of the truck. cuz i know i should beable to fit the RE's in there but the AA's are going to be tight as they are a bit taller in depth t…

I have my 3/4 thick mdf cut. Took me about 3 hours just to cut it. The only thing im confused about is putting 2 pieces of wood together. Would i have to apply wood glue to the 2 pieces, attach them together, and wait till it dries, then predrill, then screw? Im really confused. This is my first box. I dont want the edges to crack.

Vehicle is 2door hardtop jeep wrangler. I'm going to put 4 12" icons in, I can either have the drivers face towards the dash or up, port can face any direction (guessing i'll do rear, but perhaps front would be better for semi wall?). If I have the drivers facing the front towards dash, the box will not be a wall (there'll be ~15 inches on sides and top, around the box). This is what I was envisioning for upfiring, or just rotated and move port for front firing. Also, The box will be directly behind driver and passenger seats, and will have about 15inchs of space from rear of box to tailgate (gotta have some storage )

Iv been doing some research in advance of me competing next year. Although I will be doing a ton of testing on the termlab once I start building my setup, I wanted to get a starting point as it will obviously make things a bit easier. Basically my main question is going to be if anyone has actually tested the correlation between vent mach and spl readings. Iv been reading that best results come out of about a 0.05% vent mach in a build, but on the other hand you see high powered, high sd setups only using 8" aeroports that are putting up huge numbers. I may be over-thinking this, I'm just trying to grasp as many concepts as possible before I start testing so that I ca…

whats a good tuning for a subwoofer box using 8" for sq purpose and would bring out the best musicality beats for new wave songs? swing out sisters, bizzare love triangle original track, gona get your love, godfinger, reasons, etc etc i was thinking of using a sealed box, but the 8" on a sealed box would just produce hard beats.. i was thinking of 38hz on a 1.0 cubic feet? any suggestion? im kind new to SQ system, and im having a hard time deciding on how should i tune the box or go with a sealed.. i would want the output to produce hard beats when needed at the same time could produce long bass when needed.. :puzzled:

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

For those with hatchbacks and/or hatchback experience. Folding rear seats, so large enclosures will work. What enclosure has worked best for you? CRX style? Sub up, back, forward, or angled towards glass? Port up, back, forwatd, or angled towards glass? Daily driver. I'm tempted to try something in the Mazda for the uberwoofer. Can be pretty large, so uncommon enclosures can work as well. It'll boil down to having the sub and port firing forward between the seats or any of the above ways.

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?

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.

Who are the reputable box builders hanging out on this site? Going to be needing a box sometime soon.

Ok guys i have a 2006 charger. It supposedly has a 180 amp alt in it. Over the past few weeks i have done everything i could possible think of to get rid of this alt whine. Change grounds on the HU and the AMP.Changed RCA's. Ran an isolated ground to HU from the battery. Gave the HU an isolated power to an external battery. Seperate ground to the alt with the stock wiring in. New alt power wire with the stock wiring as well. Took the serpantine belt off the pully's to see if there was any catching in the alt(no catching nor was there an play in the alt shaft). Went and got the alt tested today its a good alt. Got the battery tested and its a good battery. The only time th…

Most people who made them have stopped. Who makes the best ones nowadays?

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

i know pretty much nothing about mids and highs just to throw that out there. Is there a big enough difference between running mids/highs on 2 ohms vs 4 ohms that is actually worth sacrificing the power to run @ 4 ohms? or is 2 ohms going to be good enough for a daily driver? edit: by the way if anyone has a good place to educate myself on mids/highs that would be greatly appreciated.

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.

me and my friend made a ported box tuned to 28 hz ... we followed the volume according to the specifications of the subwoofers (2 12" pioneer premier ts-w3002d4) ... we made 2 separate 1.4 cu ft boxes ... the output is not what we thought it would be ... we want it to be louder and maintain sound quality ... what size cu ft box should we make to get more output? .... should we combine them into a single box? ... if so how do you do the portwork insde?

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???

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?

i hope this is the right section butt.... Im still a nexb to box building and I want to make a ported box. It will house two sound splinter Rl-p 12s. I still need to find an amp so i dunno the exact wattage ill be giving them, but i want to give them like 600-800 a piece so thatd be 1200-1600 total. I want kind of an LSQ tuning so would 34hz be alright? (thats what the site suggests) If not then just tell me what you guys would think the best LSQ tuning would be. Then how do I figure out the dims of the slot port once i kno what hz i want??

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?
