ok, i'm gonna risk one hell of a flamming here and ask you guys. i was nomeened R-tard of the month on CA.com for saying this so chances are it's gonna happen here too, but what the hell K my question is can you guys hear the difference between a 4 ohm and 1 ohm load? now im not talking about sitting in someone else's car and knowing it, but if you have a 2x2 sub and wiring it to 1 and 4 ohm load. i have tried it with a two different amps(a 2 channel in 2 ohm bridge) and my current RF bd 1000.1. although on a 1 ohm load and lower it ponds like a bastard it just sounds too off, sort of muddy... this all applies if the amp is stable on those loads of course just curious...

i have a 1991 mustang convertible with a shoe box for a trunk. the dimensions are 10h x 9-11D x 40 width. i've been hearing great things about how the sa 8 is a great spl small woofer and wanted to know if i could really fit more than one into a box with such small max dimensions. i also need amp suggestions to run the one or two i will be getting thanks!

if your going see you there,,,cars still not ready but im taking it out anyway

The guys at kicker said to tune to 39hz for 4x12" CVR's in a 9sq foot box. I don't see many people tuning much higher than 35hz though. So should I take their word for it and tune for 39hz or drop down to 35? This is my first ported box so, I'm somewhat at a loss.

Does anyone have the specs for the Fi BTL 15" subs. I am installing 2 of them for a customer, but he doesn't have any perameters for the subs. He is putting a Hifonics Brutus 2600 watt RMS d class amp on each sub. It is going to be in an old school s-10 2-door Blazer walled off right behind the front seats. Built for competition only, wanting to hit the biggest legal spl number at USAC competition. Any help would be appreciated. Thanks

Well, because i will be removing the weight issue in my car soon, nothing stands in my way now for my next build so i need anyone's opinions on the strongest build u can think of. Any negative thoughts about any methods is 100% welcome as i don't want something that will fail. Here is one method i have been thinking about but remember, i'm looking for the best option(within costs, hehe, dont wanna spend several grand on an enclosure) Option1- Lay 2x4s on their side(so 3.5" thick) all the way around the car. Then inside of this chamber, lay 1 layer of 3\4" Oak inside. Install Angle Iron outside of the enclosure and weld 1\8" thick steel bars to all corners of the Angle Ir…

Hey guys, trying to get an enclosure made for me, but im not sure where to start. the jl stealthbox (http://mobile.jlaudio.com/products_stealthbox_detail.php?fit_id=1620) is exactly what i want, except i dont want the w3, but they wont sell just the enclosure. Does anyone know someone who could make something similar for me?

Went out to a Texas Bass Productions event today with the Sebring wit 1 12" Soundstream SPLX Quad 1 ohm.. All 3 runs it did a 151.3 Got 1st place in my class(no one was close to me). Brian(Lord Baccus) did a 151.2 with a set of bad RCA's with a Pierce Audio Products 1 off(specially made for him) 15" MOAB subwoofer, ...sorry bout that Brian..we'll et em' next time! Every ones asking about the Sundown Audio amps that me and Brian are kicking butt with....most people haven't heard of them...they are getting a ton of attention... Hoping to get higher on this single 12"...

I am looking for a good place to go to learn about building crossovers. Not only how but what components to look for, theory on how different setups affect sound, anythng and everythng.

Hi, I would like to here opinions on Subwoofer designs, Setups, And enclosures for a Convertible to produce traveling low hertz bass with the top up and down. I have built many design in my 98 Mustang Convertible for Soundoff Contest and have hit as high as 154.3 DB's in a Usaci competition.

So Im collecting parts to do a blowthrough in my fullsize chevy regular cab. 1988 k1500. Just bought a crescendo 3500. gonna get a singer 250a alt and a couple 3100s and one up front. multiple runs of 0. okay so now for my question. i have been pondering ideas on sub/box setups. I have been set on 2 18s for a while, but got to thinking about 4 15s. and idk whether to a 4th order or just a regular ported box. i can do the rregular box tuning but would need some help designing a 4th order as i have read and have yet to wrap my brain around it. My goals: Daily, Hairtricks (move air yo) not super low. 30-32 (in regular box tuning terms) not sure where that would be in a 4th o…

Im new to building enclosures and would like to know the correct type/brand of screws and glue that i should be using. Thanks for the help!

So im building my first box out of 3/4 mdf...what size bit and screw should i use? Also whats the best glue i can get...money aint really a problem right now so give ur .02...

I want to try out a transmission line box or quarter wave, whatever its technically called, and want to know if im off to a good start... I want to use a 10" Fi BL Dual 1 so 41.5fs with an sd of 310cm^2 = 48in^2 1130/41.5/4*12 = 81.7 inches... so my design looks something like this... I dont know much about these kind of boxes it just sounds like a fun project, If it turns out horrible I only lose a few hours and a little off my wood stockpile...What do you guys think about this design and these measurements?

I want to put 3 batterys in the back end of the car. I have a lot of 1/0 wire. Which is better/correct?

You can see what Josh (funny guy ) drew up, and then you can see how I tried to tie it all together so all I need to do is lay out the components just like a picture. I used circles and boxes to save time I think the only thing I am unsure of are the woofer -'s and the mid +'s (keep the reversed polarity + (2x) driver in the tower) ... I don't know where I'm supposed to tie them into the neg path - don't know if I have it close to being correct or not, as I just threw them in there. I could always move them right to the main neg lead coming from the binding post if it makes a difference.

I plan on walling off my 00 Grand Am soon with 2 18XXXs (05 model) and I was wondering if anyone could help me out. I have a couple measurements... 41w x 34d x 34h That's the external (gross) measurements. I plan on tuning it around 30hz. I was also wondering where to put the port. This will be my semi daily driver (I have 2 vehicles), and I am not looking to hit any high numbers. I want this thing to get loud and low. Also any kind of tips/pictures/diagrams/explanations/ect. for a wall and dancefloor would be greatly appreciated. And yes, I have put some effort into this by reaching out and contacting many people so please do not respond in here if I have already …

Its been a while since ive been on here... but i need some help... I'm building an enclosure for my new car (02' focus ZTS) which will house 4 10" woofers firing towards the rear of the car at a slight angle with the deck lid..
