Howdy everyone, I am looking to seal off the trunk of myv 06 impala. The box was facing towarda the rear (port/sub) facing towards the trunk hatch. But now were trying to flip it facing in. ATM I'm running 1 15inch fI bl by a 1000d sundown. I want to thrown another 1000 and strap it but from research I might have option other then Ronaldo get a btl. But for the moment, for now, I want to flip the box around. I could use some tips. Or a link robs tutoral, thanks

Hey, I am thinking of building my 1st sealed sub enclosure for two 8" Orphans from Sound Splinter. I am planning to put it in the trunk of my car (Focus zx3). The trunk measures ~ 41 wide and 30" deep. I believe a single orphan needs 0.186 cu ft (0.178cuft + .08cu ft displacement of the sub) so im assuming (correct me if im wrong) two orphans would need 2x as much, .372cu ft. What I know for certain is that the box needs to be at least 6" deep and be able to fit 2 amps on top (1 mono channel for the orphans and one amp for the speakers). And I would like to be able to easily remove the enclosure when i need a bit of extra space in my trunk, so would something lik…

2005 4Runner, looking at having 2 locations to set the box, one behind the passenger seat, one in the cargo area. I'll run 2 sets of speaker wires to facilitate. I'm 99% decided on a RLi8 or Orphan8 and here's what I've come up with. The photos are of a Costco baby wipes box for visual reference 13.5x8.5x11. If made of 3/4" MDF, I get an internal volume of 798^inches or .46^ft. If the RLi8 is .08displacement, that gives me a .38^ft box... right? I was always shit for math, but am I missing something? If aiming for .4^ft like everybody says you should for these particular drivers in a sealed encosure, I can just make it an inch longer or maybe just some polyfill? Cu…

I need an experts help, every time I try to make a box a very specific size, like certain dimensions. It automatically changes all the others I had. Example is, Say I want Side A to be 20", so I type 20. The program automatically adds numbers to side B & C. Then when I try to put in my own number in side "B" it changes A & C automatically. Even when I want A to stay the same, it changes it. What can I do?

Well it's not really a bass knob. It's just a knob but i want it to control my sub, the output level of it. And it is not in car audio it is home audio.

Not sure if im in the right section, but I emailed focal usa and asked if they could repair my 15" focal sub, and they said they no longer make any parts for it, and that i would need to get a recone kit, i emailed him back to ask if there was anybody that makes one that would fit, and no response in over a month... I don't know.. the sub kicked a$$ when it was up and goin, now the ring around the cone is broke,.. i paid around 2k a few years ago, and i can't even find a recone, something is wrong here ..lol... does anyone know where, or how i could fix my sub.? i know how to do a recone, if only someone made them.. thanks in advance.

The Big 3 Are: 1. negative battery wire to ground - just replace the negative batt. terminal and wire and ground it to the factory location 2. engine block to ground - replace the ground wire from the engine block to the chasie with a bigger wire (maybe 4 guage) 3. alternator to batt - add a fused wire from the postive post on you alternator (the one comming from the battery) to the postive terminal on your battery. DO NOT exchange wires just add a extra one. make sure it fused the same size as your factory fuse. hope thats helps Note on #2- Some cars have a batt-engine block connection stead of chassis to engine block... -------------------------------------------------…

Hello to anyone that can help me. I have the above car and I'd like to upgrade to the Big 3 to help my power. I have searched all over the internet to find the answer for this but no avail. The problem lies in the fact that the alternator is quiet hidden on the underside of the engine and the battery is under the back seat. Can anyone help me with the easiest way to do the Big 3 on this Cadi? Thanks for any help!

Well, as you can see by the title, I'm experiencing some significant voltage drop at my amp. It's an SAZ-1000d and my alternator is a 240a Iraggi. I have just one battery under the hood. It was sitting idle at about 13.3 at the battery and amp. Full tilt on music, it stays at 13.3 at the battery, maybe dropping .1v, but at the amp, it can drop down into the 11.5 range. The wiring for the amp is probably too small, it's a 4 gauge wiring kit I got pretty cheap on sonicelectronix.com, so I'm guessing that is probably my problem. The amp says it uses 4awg, but the 4awg I have might be on the small side, I'm not sure. What do you think?

Sorry for such a stupid question, but the owners manual isn't really specific about 1-ohm load with 2 subs. I have two infinity 100.9's (10" SVC, selectable 2 or ~4 -ohm impedence, obviously set to 2-ohm). I want to run a 1-ohm load on a SAZ 1000D. My question is, how do I wire them? Do I wire one to each set of speaker terminals and yield a 1-ohm load or will this yield 2-ohm? This is shown in the 2nd diagram on page 7 of sundown manual. ... or ... Do I need to wire them in parallel as shown being done with only 1 sub in the top/1st diagram on page 7 of the sundown manual, a method of wiring that I've NEVER seen before on a mono amp? If this were an old-school HCC…

So I have a 15 FI BL and 1200 watt Hifonics amp, when i turn my bass knob (volume) up to high my amp goes protect. I know it's not an amp problem because my friend had the this system for a while in his car and it didn't have this problem. But anyway i've rewired, and adjusted the amp many times and i'm clueless. any ideas? please help me out.

Hello, I would need some help on wiring two amps. I have Sundown 50.4 for fronts and backs, and will order Sundown 125.2 for 2 8'' subs in the back. I need wiring info on which things to buy to wire those two amps. I was looking at knukoncepts and wasn't sure which items to grab to have complete parts. This kit seems good for the 50.4 and I should have enough power wire to run it to the amps 4 Gauge Amplifier Installation Kit and then I got info that I should run distribution block to split the power wire between the two amps ? If so which distribution wire would be a good one ? I don't think I would need another amp kit but just additional rca's, another ground wire, c…

I wana know if I can fix my jl w3 everything is fine with it. But the wire that comes of the cone and goes to the pos or neg I can't remember witch one I will have to look I can post a pic later to I'm just wondering if I can replace that or just buy a new sub

So i was trying to find some good information about how to properly install components. I was reading through build logs (including Shizzzon's 25 page one) and every time it came to their set-ups, it seemed as if they gave only 1/2 the information. I have a Boston Acoustic Pro 60se set i would like to use as my front stage. I also have damplifier pro from Second Skin. My question is rather elementary and i apologize for that... but what's the best way to put them in? I would like to avoid the speaker pod approach. I've heard so many different things. Should i make a 3/4" MDF ring and mount the speakers to those? I just honestly have no clue here. And tweeters should be mo…

Hello I am having problems with the JBL GTO 1514D. I have made the enclosure to the jbl specifications. It is in a 3.45 cube box with a 4 inch PVC port that is 13 inches long. However I am getting a LOT of port noise, which makes the audio very dirty. I am using this subwoofer in a home audio application. When building the box i used liquid nails to seal the joints of mdf boards, and I also used 1 5/8 coarse thread drywall screws. After this was completed I coated the inside with fiberglass resin to fortify the interior. The sub is recessed and down firing with a back facing port the amplifier is also on the back. These cutouts have been sealed with silicone, as well as…

What is sensitivity? The sensitivity of a driver is typically defined as the sound pressure level of the loudspeaker given 1 watt of power input, measured at a distance of 1 meter, measured on-axis with the loudspeaker and measured in infinite space with the loudspeaker mounted to an infinite baffle. While the later part is typically assumed but not stated, the former part is the reason you generally see “1w/1m” or “2.83V/1m” stated along with the sensitivity specification. But wait, is 1w/1m equal to 2.83V/1m? The answer is only for an 8ohm impedance driver. We know this because of ohms law, where Power = Voltage^2/Resistance. If the load is anything other than 8ohm the…

This may sound a bit noobish, and it may be.. But I am trying to enter these boston acoustic 4.5" woofers into WinISD, and it keeps saying it fails in many different areas,so am I entering something wrong, or are these bogus specs on these woofers? These woofers do sound good for $15, but I think the specs listed may be wrong please help me?

Do crossovers really making your bass louder? If so, any suggestions for a good one?

I have two 100watt rms Floor house speakers, they are 3-way and are 12" in size with a 4 inch midrange and a 2 inch tweeter. they are sanyo AVS 500 series, there is no info anywhere for these speakers. They sound great except at high volumes they do not have a crossover in them at all, which I think is kind of dumb on the company's part, these are good sounding ported house speakers that bump pretty good, they can get the walls rattling and there from the 90's. I would like it if anyone had any ideas to what frequency crossover I should get, as in what frequency's should i aim for, for these speakers? they can hit down to 30hz very nicely, and you can even slightly hear …

Hey Guys, I am new to this forum and throught I would try to contribute. If anyone is looking for reapir manuals, owner manuals or service manuals for virtually any type of car, there is a FREE ebook at the address below. I asked him could I download and share it, but he said he prefers to have people come to the website. The site itself isn't the best, Sometimes there are annoying ads and surveys. The ebook is only a couple of pages, but it gives a list of places online where you can find almost any service and repair manuals, even for very old models and trucks. I would highly recommend to download it and keep it on your computer. Website - 1000’s of Free Car Van a…

well after about a month or so of driving with no rear view mirror i decided to get a new one. this is the second one i've had to buy since i already broke two. both times the mirror's arm has snapped from window flex/vibration. i have a nissan and they use the same mirror components basically in all their vehicles. one being the arm which is that same on every one. i don't know how familiar anybody is with the material used on these arms but to me it looks like a metal of some kind and plastic. feels strong but obviously snaps easily from all of the vibration. my theory is that since the mirror moves to a certain point and can't move any longer. the arm is the focus of a…

Not that newbie’s are dumb. But there have been a lot of posts on here lately that if they read the pinned thread about them. It would make the post end a lot sooner or not even start Some of those threads are what is my tuning frequency? I like reading book and proving if they are wrong or right. So one I like is a book by old colony sound labs called loud speaker cook book. It’s a good book on the general subject of box tuning. And hay you may learn a thing or two about alignments. More then what a box calculator will teach you. Another subject is what components should I buy? I do not know because it is better to listen to them yourself. I for one prefer a…
