I am going to use my 12" in a room setup for listening to music, it will be on a 500 watt dayton plate amp. what size sealed enclosure would you recommend, looking to keep it under 2 cubic feet.

Would you recommend multiple ports are a large single port for 2 Q 18 D1s with cooling and the extra spider on an AudioQue AQ2200d, in 20 cubes after displacement tuned to 28 Hz? Car is a 2004 Tahoe with the max box dimension limits being about 27 H x 49.5 W x 36.5 D. I had a few designs floating around, I think one was with 4 8.5" round ports, one with two slots along the bottom of the box, and one was a rectangle in the center measuring 15.5 H x 19 W, so 294 in^2s area and was 22.35 in. long. The dimension limits leave about 7-9 inches between the box and the rear, 7 at the top and 9 at the bottom. I was thinking the large port might not have enough port speed, but …

So I just bought my new car, a toyota celica, and I am going to have a custom box built for my q 18. with a kicker zx750, how many cubic feet should I go for? I am looking for a flat frequency responce and a good balance of sq and spl. I know these are all really rough terms but I just could use some advice.

hey guys i have a single cab s10..i plan on running a single 10 between the seats inverted. i have came up wit 2.42cft...would 2 4in aero ports be big enough?? the guy i am buying it from said with that little of power i can build a 2.0cft box and gain a lot i plan on porting it out the side...would 3 in from the wall be enough room for the port?? my back wall is 52in. and my box is 49x13x6.5x10...also i am goin to use 1/2 MDF..any suggestions??

i have been working on my box design this would work real good with my trunk space. http://www.soundsolutionsaudio.com/home/bo...ideboxcalc.html is the box good to build or is there way too much port, fi recommends 12-16 per cubic foot of enclosure area? crap it only posts the default box... my box is the following: box width 35, box height 17, box top depth 19, box bottom depth 19, box thickness .75, square port width 4, square port length 2-16

A buddy of mine has an Orion amp, I'm not sure on the model of it but it's a 2400 watt amp and the yellow ecp light I think it is comes on and there is no output from the sub so I'm just kind of wondering what the ecp light is for and why it is on.

So I just recieved my 15" SSD with copper coil in the mail Thursday. I originally planned to go sealed in about 2cuft, but I have about 3.1cuft after all displacement to play with, so I was thinking about porting it. I wanted the install to be strictly sq, so I was thinking about 28Hz or so. My question is, has anyone here tuned it that low? If so, how's the sound quality? And if no one has, what tuning would you recommend for a sq setup?

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.

Guys I have purchased some ssd 15's from a guy and was wondering if I could send them in to get the bp power upgrade or if if that is something that has to be done at the time of the first build

Nevermind, PM sent... thanks. Delete this is you like... Joseph K.

Hopefully someone can help. I found a 3hp motor, but it only has the 4 bolt layout where the basket secures. I've seen a few of these motors rebuilt w/ fi softparts so i know it can be done. My question is what cone assembly, or coils and spiders should I get (assuming I use FI) to make it perform similar to an eclipse TI? Also, what basket should I use, or is there one that I can use with a four bolt pattern? I need some guidance and am a little knew to this so bare with me please, and maybe a price range so I know what I'm getting into. Thanks for the help. Also, when do the new woven tinsels come into production, and will all products be switched to this? It's …

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

I was banging it at mid level volume (25 out 0f 60) for about an hour. Its getting 1200 watts rms from a 9.1 at 1 ohm, my gains must be set a little to high. I bought an old bass mechanic cd from circuit city yesterday, this morning I put it in just before I left my home, by the time I made it to work I was at the end of the cd and was listening to test tones, they went from 20hz all the way to 99hz, I only listened up to 35hz before I cut it off. I felt my amp before leaving the vehicle, it too was warm, I have never been able to get my 9.1 warm before. I then checked the BL in the trunk, the dust cap and surround were warm as well. I never once smelled any coil or glue …

How much power should i put on a BTL 18 if i plan on running it for fairly decent lengths of time, 15-30min, at high volume. Is 4.5kw too much for that kinda usage... It'll be in a rather tight ported box

Approximetely 1-2 weeks ago, I decided to I needed a new sub. There was a big upcoming sound competition in my town and I needed something to beat a rival of mine that had more money, and more time,haha So I knew Fi was a good place to go. At this point, i was extremely focused on beating my rival and so I decided to go all out with my power options (JBL BP1200.1) and get an 18" BL fully loaded. This worked pretty good for the competition. Didn't do as well as expected, but we tuned the box way to high in a poor guess on our part of the cars freq. it was around 41 and we were tuned for 47-49hz. still, we managed to hit 141.6 at the headrest with 1400 watts of power, stoc…
