SPL & SQ / Fabrication

So basicly, box in trunk, 2 18's and 1 amp. for whatever db and iasca i guess, but for iasca i would have 2 amps

say you have a box with the cuft you want to port it with but this box has a reallly strange shape will that change the port size,length, or anything at all? its going to be for a ssd 12 the box has 2.12 cuft going with a round port

okay, so I drive a 1995 honda prelude. I just got my nightshade 12 about two weeks ago =], I am running it with the saz 1500, I have also done my big three. I feel my nightshade isn't at the full potential but, it could just be my box. Off the top of my head I can not tell you my demension, all I can tell you is that its 2cuft at 33hz. I am planning on building another box very soon. I would like to know what input anyone has on they're 12" nightshade and there boxes and how they sound, also anyone with a prelude and where the have there sub mounted and the port faceing. Thanks, Jordan

Hey all. Im looking for a design for 2 12 Sa's in my PT. My max dimensions are 39 W x 15 D x 20 H. i will be running them off of a saz 3500. Im looking for a cross between daily and burp if there is such a thing. Ive been told in the PT to run port up subs up with slot port inbetween the subs. I had someone making a design with cut sheets flake on me and I have to have a design by Monday when i have a shop to build in. I know this is asking a lot but if anyone can help me out it would be appreciated. the design can be basic as i dont have much room to work with. I just need cut sheet list and I should be set. Tuning should be right around 33-35 hz. and box should be righ…

I posted under another topic but calculated the wrong numbers so here is the updated version. The other post topic is misleading so that is why i posted a second time.

Hello all . Im in beginning stages of design for my 2002 PT Cruiser Enclosure. This will be my first year competing in the lanes for SPL. I know its correct to have a daily box and a burp box, but I would like to get as close of a mix in one box as possible. My initial thoughts would be to have subs facing up and slot port facing up as well because of the lack of room. So far I am just looking for any advice I can get. Max Dimensions: 39w x 20h x 14d. Would prefer port in between subs but If it doesnt make a difference, im flexible. Am I on the right track? Any help would be appreciated.

Hi folks. I just picked up a pair of L7 10's to go in my single cab 06 Sierra. I would like to go ported if I can make it play loud and hard enough over a sealed setup to be worth while, however I am not sure as to what my best bet would be in terms of porting for this. The enclosure dimentions will be18"Hx57"Wx7D which is good for 2.91 cubes if my math is right. I've been running 1 12" powerbass L12 in a 2 cubic ft ported enclosure with the sub behind the pasenger seat and one 4" port firing up from the top on the oposite end and it has sounded pretty decent, but I want to run more power and get louder and due to mounting depth issues a more substantial higher power ha…

Okay, from what ive read over the past few weeks ive decided that i want to go with an active frontstage. My DEH-7800MP is capable of this from what ive read. I plan on glassing the front doors to accept a well acoustically matched woofer and tweeter combo, i was hoping someone here could give me some suggestions on what woofer and tweeter to use so that i have little flatspots in my sound. Also for reference i hate harsh pingy tweeters, i don't particularly like all my highs to sound like crashing symbols! lol.... With switching to an active front stage this also means i will be completely losing my rear audio am i correct? Thats the only thing ive been confused about! T…

i need a box build for my sa-10's

can someone help me, im going to home deopt today, need some dimensions. can anyone help, i would greatly appreciate it

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

Im in the process of a biulding a new setup which will consist of a 12in FI BL fully loaded with a Hifonics Brutus BRZ1700.1d. My last setup was a 12in FI Q with a Hifonics HFI1000.1d and i had a box i built myself that was 2.5 ft cubes tuned to 33hz with a 2.5 in slot port width. I had it in a chevy blazer and i could hear the air coming out of the box? How do i limit that noise so it sounds clearer? Vehicle: 2006 Nissan Altima Location:Trunk Space Available:30x18x15 Sub: 12in FI BL Music:Rap and Dubstep Goal: I want it to have the best SQ while doing well with SPL

this is going to be my layout for a new box ports gonna be up top they will be coming through the decklid and the subs are gonna be firing towards the trunklid.what do yall think of this setup?

I need help with an enclosure I'm building my enclosure is 2.51 cuft after displacement it will hold one fi Bl 12 ran off a T1000 amp I would like to tune it to 32 HRZ with what info I have come up with in order to tune it to 32 HRZ if I go with a 4"port 10.3" long it should be around 32HRz does this sound right my enclosure is 16" deep 54" long 9.5" tall in the front and 7.25" tall in the back it will be up fire and I would like to run the port off the front witch is the side that is 9.5" I'm working with very little room so I can not change the die mentions of the enclosure much if you have any suggestions on how to do this right please let me no add if …

Just finished an install on my 95 probe. Put a DD 3515 in 3.5 cubic foot (after displacement) box with 2 - 4" aeroports at 17.75". Hooked to a RF 1000a2. Box is a standard CRX design. I've been toying with box placement and right now its sub up port to the side. Sounds decent, but a friend had this exact setup in his 98 Explorer and it was quite a bit better in there. So I'm assuming the problem is related to box design, tuning or placement. Any suggestions??

want good LSQ setup one si bm 12

I just had a box built for my 2 icon 12's tuned at 30hz.I had it metered at my local shop.they said it was peaking at 40hz.is this normal?is it cabin gain etc.

Hey guys, I was messing around with some box plans, and for the recommended box for two rl-i 8's (.6 CF @35 hz) the port has to be over 106 inches long. That is almost a 3 CF port! Anyone know how I can get the length down some? Check my math, but I'm pretty sure this is right.

On the Termlab im hitting a 144.3 sealed up at the dash with a sweep. its in a trunked cavalier. i just want to know if i can get that score a little bit higher? would holding the trunk lid, sunroof, or doors down during a run help? would more room for air to get into the cabin help? does subwoofer box placement help, meaning how far away from the trunk lid it is, also how about rear seat folded down half way help? how about front seat positions? kind of just trying to get as much of an edge as i can. with the 144.3 run it was all set up for daily driving, not much tuning done at all, as in i didnt play with box position, or seat position or anything like that. i just k…

ok so the car is a 98 Dodge Stratus. I have to have access to my spare tire and would prefer a removeable enclosure but thats probably not happening. What i have now are two boxes 3/4" MDF 3.13cubes each tuned to 36hz. i want something that'll look more custom and less amateur. I've considered finishing my boxes and what not but its really not worth it to me, i'd rather just toss the boxes (not actually throw away) and start with fiberglass. I'm pretty good with fiberglass but never tried it in cars/audio, i think i can manage though. what i really need from you all is ideas on how to make this look good, i'm wanting front firing subs like they do now, and my amps a…

where did it go!?!?!?

Anyone wants to donate some blueprint of boxes that could fit here sub is 9515 w/ strapped saz1500 amp Length - 31.5 inches Height - 18 inches Depth - 22 inches These measurements are the space left to be exact, no box yet. Assuming 1inch MDF will be used and I'm eyeing for 4.5cu.ft. or 5cubes plus port tuned to 40-42hz. Sub is facing up and port is facing the rear hatch door. With the given depth, there's a 4inch gap remaining before the box/port would hit the rear hatch. Id appreciate your suggestions. Thanks
