Hey all. I'm going to build a sealed box for my 10" Fi Q woofer. It says the mounting depth is 6.5" for that driver. How much clearance should I have behind that woofer in the box to ensure adequate ventilation? I want my box to be as shallow as possible to save on some trunk space. Thank you.

Whats the best kind of wood I can use to get the full preformace out of a 18'' FI.BTL with these specs? Dual 2 Ohm,Cooling,HiXm Coil,Induct heat ring,And Daily option. I plan on buying four!!! Also the recommended option is 2000 Rms but Steve Meade told me he gives his 5000 Rms each he has four also. ''audio-neon'' told me ''meade knows how to build enclosures to compensate for overpowering the woofers thats why he gives them that much power''. If thats true how will I make my enclosure inorder to do that if I plan on overpowering the subs. Is that a good thing if I have a enclosure do that or just stick with 2000 Rms each (or maybe 2600 rms if so). FI.BTL Specs (BTL18) …

Hey guys, I have an 18" BL running at about 1200 watts and this thing moves air. I've had some problems with my rear deck flapping up and down no matter how much I seal it off. It seems air is always getting into it. It will even start shaking my rear seats and moving them in and out (they are foldable). My rear speakers currently are a sealed speaker. In such that they are an older JBL pair I got from a friend's lincoln. So the cone isn't being moved or anything by the air. I don't ever use rear fil, i just threw them in there to help seal up the rear deck and so on. My question is this though...by attempting to seal up the rear deck (dynamating it, covering all the hole…

Hello everyone If anyone has the free time and could come up with a simple box for me that would be great. Id like to run them sealed and i will be giving them plenty of juice. ab 400.1 @ .5ohm. I have the electrical to back the amp up. The box will be going in a mazda 3 hatchback. Thanks for the time. Give me a email address and ill send over a few bucks via paypal. Thanks again.

Hey guys So here goes Have my two Fi Q18's off a JBL BP1200.1 When i first installed them they moved in phase perfectly it was actually awesome to watch ! Now they dont and output is down noticably, So.. .. I pulled each speaker out of the box and checked for physical damage, none, no burnin smell AT ALL and no loose glue that I can see, second i Tested each speaker on its own, works fine, i checked coils, fine they all show up the same. Im runnin dual 2 ohm in series parallel and am getting 2.2Ohms on the VMM for my final load , fine.. Speakers were making a funny noise sort of a raspy sound right after they stopped working in phase... Unhooked em right away , checked, …

I have a 94 cadillac fleetwood I am trying to find the best way to put 2 18" btl fully loaded in the trunk I have 2 t40001d rf amps and enough juice to run it all I just need to find out wat everyone thinks will be the best way to due it. Also is it ok to put the ports on the outsid of the box so that way i can keep the cubic foot in the enclosure at the max

Is it ok to run 3 subs off 1 amp without any major worries. I was thinkin 3 15" BL's off 1 RF4000.1. What do you think? Or maybe I should just shut up and run 3 SAE-1000D's.

ok today i was playing my woofer while driving for about 1 hr. after i got home and parked, i went to the rear and touched the dust cap of the woofer and it felt warm. i was wondering if this is normal and is there anything i should be worried about? my d2 18" bl is being ran on a kicker 1200.1 @ 1 ohm. head unit gains are set to 0 and amp gain is about 40% turned up and bass boost aswell. woofer is in a 9 cube ported box tuned to 32 hz.

i have a 01 saturn L300 4 door. i pulled the back seats out and throw a bl 18" back there. now, im going to be getting another bl 18". this time the 2 will be in the trunk. how should i have the subs firing and where should the port be located. (firing). the backseats will remain out for my amp rack.

Ok, I am a ported enclosure built from pound that sound for 2-12" Fi Bl subs. I built a cardboard box like he asked as big as possible to fit in my trunk. It ended up being 39" wide x 13" Tall x 15" deep. This was sitting on the ledges on each side of the trunk and the spare tire hole being empty on the center. The box has to be dropped in from the top and has about an inch and a half gap on the top, and the side facing the rear of the car. Will this be enough space for those subs? I notice it asks for 1.8-2.5 per sub so I think I am a little small unless I would extend the bottom center of the box down into the spare tire well. HMMMMM?

I would like to get a replacement gasket for 12" SSD,is it possible?........Also whats a good size sealed enclosure for 12" SSD ?

Alright guys im new here and don't know if this is the right place for this but i have an old box for 2 15's. Its 10 cu.ft tuned to like 33 hz. Im wanting to get some new Btl N2's. But im not sure if i want to stick to 15's or cut the holes out bigger to hold 2 18's. What do you think i should do? Never had 18's. So Im trying to squeeze the most spl's out of it as i can. Also i will be using my Memphis Mojo 4kw amp.

I'm planning on a new system in my 1970 oldsmobile cutlass. I wanted it to include 2 btl subs with my. rockford fosgate t4000bd amp. I was wonderng if amlnyone has any sugestions on any aftrmarket alternators. I was also wondering if Im able to just add a second alternator to my car or would that increase the voltage were it would screw up the cars electrical as well as burn up the amp. -Thanx, Jack

after beating my subs for 8 months it appears my spiders got real soft. if i pust the cone its not as stiff as it used to be. so i was wondering. if i recone my subs, how much increase in output will i see. a rough estimate will do. thanks in advance.

So i have a friend who has two sp4 15's. He is trying to run them in a box that is roughly 4 cubes net after displacement. I keep telling him this is small for them but i could be wrong. His port is external. running it on a bc3500 Any recommendations to help him out would be appreciated.

Here is my problem/hold up. I am getting a new truck, one for pure audio fun, full size of course. I will be doing a cut through, so the entire bed is game. I want tons of SPL, enough to make your stomach almost turn. I want 4 15's and am not sure what to go with BTL or BL. I know I need some good amps to push them. What all power wise (wires, alt, extra batteries) would I need and about how much/where can I get a alternator from. I have some crap P3's now and want to do a massive jump up. I got addicted and my friends are killin me, want to destroy them. Thanks

I have a BL 15 dual 2 ohm wired to 1 ohm. How would I find the resistance? On the specs page it says it is 1.5 ohms, but since I have it wired to 1 ohm would it be different? I am kind of lost as to what my target voltage should be. Sorry I am just starting in the car audio scene so pardon my noob question

I'm running an SSD10 in a ~.8cuft sealed box with 400W from a PDX. I'm mostly satisfied but it seems to lack the very bottom end...just doesn't have any oomph and sounds like response rolls of pretty sharp. I only notice it once in a while on certain tracks where I expect to get a low hit. I've had this sub for a couple of years but I swear the enclosure specs used to call for a larger enclosure compared to the .2-.6 I see now. That's why I'm in the bigger box. Can this thing really perform well in .3-.4cuft?
