Technical Info & How To's

Im wanting to build a hybrid woofer but have never tried this before. i have two 3 bolt Memphis MOJO motors and i want to know if i can recone them with either some 15" SSA or Sundown recone parts and run on an SAZ-3500. What do i need to know about these motors before to know what parts i can use and what parts should i use? I know the motors have 2 magnet slugs that are iirc 1" x 8.5" and the oem voice coil is a 4 layer 3" coil. can or should i use an 8 layer coil and can i use the same basket as the soft parts im using use and redrill it to fit the three bolt style?

I just ordered 3 knu fleks 4g power wires for the big 3 upgrade, one thing, it doesn't say how long the wire is which is kind of annoying but anyway: My battery is a superstart 550, don't know if that means 550 amps or not but i doubt it. Alt is just stock, i drive an 01 sonata gls, so im guessing its probably like 90 amp alt. Im running 1/0 knu klm for power and grounds to my fi bl 15 (09 version) off of 1 ohm, and i doubt im getting near even 1000w, and prolyl mad voltage drop too. My question is, about how many amps will my electrical be putting out after the big three upgrade? Will it be enough to get 1000w+ out of my shit? Thanks.

I just found this link, you guys should check them out if you get a chance, lots of cool differnt tones and sweeps Test Tones Link

I drive a 200 Honda accord and was wondering if i need to do anything special to put the alt in. of course disconnect the battery + and - and let the car sit for a while. the alt is a 200 amp dom iraggi alt and it looks awesome. cant wait to get it installed tomorrow, props to dom, and i hope it is as great as he explained it to be. any tips or tricks to make the install any easier will be very much appreciated. i am mainly wondering if i will need to change anything computer wise to get voltage to where it is supposed to be, or will the computer detect this and regulate it automatically. thanks again. mike.

im trying to achieve 2 things. for the port, where it ends (inside) i'd like to know what size router bit to use when i make a pass from each size to make it a perfect half circle. also, where the port turns 90* what size bit should i use to get a full turn on 1 piece of wood. im going to start my box build without my gf's dads tools this time. im going to buy a router and the jasper jig and the 2 (or 3) bits i will need

hey guys im kinda new to wiring subwoofers so i need some help. i hear now a days people are using these speaker pins and banana plugs to wire up there subwoofers, how do you use both of them? and which one is the better to use? one more thing, what gauge wire would u use to wire 2 18" fi btl's? thanx

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…

So there isn't a topic on isobaric mounting, I figured I might as well create an advanced discussion on it to answer any questions. We might have an idea that isobaric mounting allows us to use smaller enclosures, but why? The important parameters are: Re Le Bl Mms Cms / Kms Rms Sd from these we can characterize a driver/system using Vas, Fs, various Q's and so forth. When we mount two woofers isobarically the Electrical parameters Re, Le, and Bl will change - but it's like wiring a dual coil driver, we dont really change much here. The Mechanical parameters Mms, Cms, Rms, and Vas will change while Fs and Sd will not change. Since Mms and Kms have both doubled, and ther…

first thing this system is going in a 2014 Jeep rand cherokee. I already have some pieces and Iam looking for some addition recommendations. I already have the box which was ordered from high output enclosures tuned to 33hz birch box, with kerf port just received my sub 18” XCON, the amp I will be using is a Crescendo symphony 1500.1. I plan on upgrading to a nice set of components which I will be using the crescendo 800.4. need some component recommendations. I plan on using the RF 360.3 for my processor I want to keep the Uconnect system in my jeep. My biggest concern at this point in time is Electrical advice... Batteries? wiring? Will I need a second Batt for the bac…

I'm getting some measurments together to do a ported box for 4-SA-8's in a 4cu net ported enclosure. Using 2 of the 4" precision ports I would need each to be 11.90" to achieve my desired tuning of 35hz. I have no clue how to figure the displacement of the ports at their desired length. If someone could give me the formula or better yet just figure it out for me that would be outstanding . I have plenty of time since the subs won't be out till feb.

I just installed a HID kit today that i recieved for my bday... instalation was alright. It came with set of bulbs, set of ballasts, and some small 1x1.5" black cube with power and ground and stuff... but my right bulb flickers alot.. and sometimes just dosnt turn on. And the left sometimes dosnt go on. But i believe i need a relay switch.. not sure where to get that.... if any other questions to help me fix this please ask!

So I ordered a new tool for the tool box, and received it in the mail today. And the tool of the day is: a Vellman HPS10SE O-scope Now how exactly do I go about using it? (altough it has an auto fucntion) I'm pretty much going to be using it to set gains at work and at home on my own projects. I have all the test tones one could need thanks to AutoSound 2000. Basically I need to know how I hook it up to the amp to measure the wave and what should I be using as a load? I've heard/seen of resistors (dummy loads) or reactive loads (speakers). I would assume that using the reactive loads would be better, but I have been known to be wrong before. There is a centre pin and wire…

Im sure most of you know the trunks in these cars are terrible for bass. Looking for some ideas on what i can do. I have sound deadener on the trunk lid an sides and a little bit behind the back seat. I don't wanna cut out the top of the back deck supposedly doesn't gain much. was wondering if cutting the metal out behind the back seat helps at all? BTW im running 2 xcon 15s with a crescendo 3500

So I’m getting pretty sick of free handing all my boxes, jigsawing and using screws, my question is what size table saw does a guy need to do basic boxes; like max 24” cuts. Also, what kind of nailer and gauge nails do I use to replace screws? bonus tip* routers? Which one is a good buy to do cutouts and round overs? Thanks ALOT!

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…

Ok, so I'm very curious on learning about electronics, and repairing/diagnosing. First, I want to get opinions on where do I need to start. I've read a pretty good bit of info so far, but seem I've limited to what I can learn without doing it. As I'm a more hands on type, only way I can learn and understand is if I do it. And or if I'm confused about something, having somebody connect the dots I'm missing, then it clicks and I understand. So far I haven't found much on actually repairing car audio amps, most is just electronics in general. Which I guess is the same, just seems I get over my head easy because I don't know the basics yet. Basically I'm looking for pointers…

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…

I was asked by Denim to repost this for our SSA family. Original post is here: http://customizeyourvehicle.org/viewtopic.6481.html but anyways, here we go. I'm gonna seperate the sections to make it easier to read. If you have anything to add please do so. I am going to break it down into seperate post just to make things easier to read. What is the advantage of dual voice coils? The primary advantage of the dual voice coil speaker is wiring flexibility. A single dual voice coil driver offers the user three hookup choices...parallel, series and independent. In a parallel hook-up the drivers impedance will be half that of each individual coil (a dual 4 ohm speaker would…

When building a sub box and putting pieces together how long do you clamp each pieces with glue until you pre drill and then put screws in and move onto next side?

I will be breaking down the tools/supplies for putting a bass system into my car So what i am anticipating is tools, and making it so that i can turn my sub on and off when i am driving. Tools i have-Wrenchs, drills Tools i think i need-Soldering iron (voltage help needed) and a heatgun dunno much about these two Now for a sub on and off button or knob, this is so not ALL the time i have bass, some people may want this do not. I will be having a mono amp and i dont know if il have to solder. Now for wires: 0ga, RCA cables, i dont know if ill need 1/2ga Subs i will be getting-15" Fi BTL Amp-Undecided but either a audioque 2200D or Sundown Audio Electrical- Possibly a seco…

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 …

So im helping my buddy hook up his little system but ive come to a blank.. he wants an amp for his sub then an amp for his speakers. ive done this type of installation only once and i think i got lucky but ill get to the point, um how do you wire two amps in one car ? so to my knowledge, pos and neg from battery to distribution block, then two pos and neg to the two amps. right? for the headunit im also a little confused, both amps only have inputs so how do i split the rcas? im guessing some type of wire splitter for those and both amps have two inputs? and for the remote, do i use a distribution block for that or is it possible to put it in one amp and then to the o…
