I'm Looking At Building A Ported 8 Cubic Foot Box For The SSD 18. Someone Couldn't Help Me With The Dimensions And Port Size, Could They? I'd Seriously Like...Appreciate It. Also Specs For A Square Port Or A Slot Port, And How You Make A Square One. I Suppose Its Just A Hole In The Box Panel? The Sub Is Firing Up, Port Firing Back.

Ok, so my fully loaded 18" BTL should be here on wed., I want to get started on the box in the next couple of days. But I have no hands on experience with this sub, and I don't like relying on a computer program. So, I need to know what size box/tuning I should be looking at for it, all info listed below. 18" Fully loaded BTL, powered by an MA Audio HK4000D @ 1 ohm, so roughly 3500ish rms. I don't listen to THAT much rap, but still want it to hit the lows.I listen to stuff with a lot of double kicks, which I don't want to sound really sloppy/mushed together. So, cliff notes. BTL 18, 3500rms, and lots of double kick drums Also, PLEASE do not reply if you do not know what …

Big C Again, I Was Wondering Within The Parameters Of 13Hx16Wx12D Would Be A Good Match For A Q 12" In A Sealed Box? Input Greatly Appreciated. Amp Is A Sundown Audio SAE-1200D. Q Has BP Power.

Okay so I'm going to recone my Q series to a dual 1. Its an older Q d2. I'm running a mmats d300hc to this woofer in a closed box about 2.5 cu ft. I love low bass. I want a recone config good for everyday driving and music. Mostly rap. Go with flatwind? Or copper? I want some leeway to have some fun so should I go with bp options for cooling? Enclosure reccomendations? About to order this shit tonight confirmation in the forum would be optimal

12" BL D2 Daily Flatwind Cooling @ ~1200RMS. 2.25cuft @ 32Hz. Just wondering what the subsonic filter is recommended to be set at. Right now it hits all the lows with ease when set at ~25Hz. (Soundstream TRX1500D)

I have Term-Pak and am looking at the graph for a box for my BTL It looks horrible. Is it just me or does the sub just plot poorly? I used the specs off the site. I'm using a model of 4ft^3 @ 32Hz

Anyone have custom box dimensions for two 15" ssd?

Anyone have the T/S params for a fi x 10"? Team FatStig

I am pretty sure I have neither the room or the amp for 2 of the Qs but I am getting 2 of em for $260 If I did want to change amps and run 2 Q12s, how much air space would I need to do them justice in a sealed enclosure? I have started to consider using both after a day to think about it. Initially I was only going to use 1. So, I guess I have 3 questions enclosure space for 2 sealed enclosure space for 1 ported enclosure space for 1 sealed Thanks for any and all help Jman Oh, the car is my 2001 Trans Am, I kinda want to use the space available on top of the gas tank in the rear hatch and get my ttop space back. If not familiar with the hatch in a 4th gen f-body, chec…

I have an 18 SX that I would like to have reconed. What is the procedure to have the sub sent in and reconed? What would the estimated price and shipping to 30286 (Georgia) cost? I emailed Fi Car Audio about a month ago, but unfortunately, I never got a reply. I've sent a couple more emails here and there, but still, no luck. Anyone have any ideas of how I can get in touch with them? I would call, but I was unable to find a phone number. Many thanks, Mike

Umm I'm having a bit of a problem. I need someone to go into bass box pro or whatever you like and design me a box. The external dimensions are 27Hx40Wx25D. I'd like it ported. Please don't tell me to get different subs or a different car, I just can't make that happen.

So heres the deal: I bought 2 12 X's A few months back during the clearance, and I put them in a horrible prefab ported box with circle ports and after about 2 days, a blown out side panel. Supposed to get 1.6-2.2 cuft in a ported box, I think theyre getting 1 each. It sounds decent I guess, but if I get it past about 1/3 volume, I get the worse port noise I've ever heard. I just got back from Home Depot, and I bought a 4x8 sheet of 3/4 MDF. I'm planning on starting the construction of my new box tomorrow. I've decided on sealed, because to be honest, theres about 0 chance of me successfully building a ported box. Here are the stats for the X series 12's: Sealed box: .9-…

I have searched but not really found anything that really tells me what it is, how to reduce it, and how it affect everything. I figured brilliant sublike people around here would have some ideas...

Need help with deciding on building enclosure for (2) 15" FI BTL. Going for ~36hz This is the amount of room i would like to use: Width = 36" (Max width due to wheel.) Height = 24" Depth = 22" Would be sound better if the sub face up or sub face back. Also the same question apply to the port. All of this is going inside a SUV. What are your recommendation for the port? If the above measurement are small, please give me some recommendation. I would like to keep the box small but also sound good.

I am interested in two 12" BTL N2 dual 1 ohm with all options and daily coil. I have 3300wrms available but I will set gains accordingly. I would like to keep the enclosure as small as possible but within an optimal spec. What is the recommended enclosure size for my setup? Thanks edit change of plans

My enclosure is 1.3 cu ft sealed, should I add some poly-fill to soften the boom a little if so how much should I use, 1lb, 2lb, somewhere inbetween ? Thank you.

1- when are there going to be stickers 2-when are you going to make a badass hat?

The website says between .8 and 1.5 cu. ft. for a sealed enclosure. Could someone give me a more exact size? Or at least tell me what would be the difference in sound if it was placed in a .8 cu ft box vs a 1.5 cu ft box? I'm currently running an IDQv3 12 and was given an exact volume size for a sound quality setup. What do you guys suggests? I listen to rock and electronic music. Thanks in advance!

Does anyone now what happens to your cars electrical system when you strain it? cause i have not upgraded my alternator and my capacitors and lights dim horribly, only upgrade i got is a a red cap battery

I'm going back & forth between using 2 15" IB3's & 1 18" IB3, but am a little concerned about their output between 50-80hz. I'm going to use 8" pro audio midbass in my doors, but from what I've read they shouldn't be crossed lower than 80hz. Does anyone have any input they can give me on the IB3 line playing these higher frequencies?

Hey guys, my enclosure is nearly finished. The specs are.... It's 3.97 cubes before displacement, so I am guessing around 3.5 after due to the sub displacement and the bracing. The box is tuned around 33hz. I've tryed it in my friends vehicle and it pounds pretty hard. Not 100% happy yet. I'm thinking that's just because it's not broken in yet. I heard it in a Ford Expedtion, but the sub will be going in a 96 Cutlass Supreme. Hopefully it will get much louder. I'm powering it with a JL 1000/1. But what I'm wanting to know is are those good specs for the box? That's about the biggest box I could fit in the trunk. Help would be appreciated!

I have been told the 12 ssd weighs 25 pounds, i was curious what does a stock 12" Q weigh? Just curious because i might get one if i can sell my 2 12" HCCA's old schools.

What is the lowest amount of watts to feed a 12" Fi Q and still get decent/good performance? I'm shopping for an amp and want to see what my options are.

Forum, I have a unique situation and was looking for help. I have 4 FI BL subs but 2 are dual 1 ohm and the other 2 are dual 2 ohm. Can i run these 4 subs in the same enclosure and what final impedence will they have wired in series or parallel?? I have 2 Fosgate 2500-1bdcp amps that can be strapped together at a final load of 2 ohms.

Hey i just bought a 15" bl. i was looking around and everyone said a 4cubic box would do but anyone have any cut outs or exact directions. im not sure what i should tune the box to? hertz?? anyone have any suggestions!
