General Audio

can any one help and give me the equations to calculate the box airspace and tuning on the box ... bcause i want to learn a very accurate way to design boxes like calculating them by pen and paper without using a software. PLEASE HELP

I'm hoping someone can point me in the right direction. Forgive me...I'm not very knowledgeable about this stuff. I have a 2001 Chevy S10 ZR2 (4X4) I ordered off Crutchfield and they sent me my new Sony Digital Media player and a wire adapter kit. The problem is it appears to be the wrong adapter. Crutchfield only has one option for my year and make and it's that one http://www.crutchfie...ss.html?tp=2977 My GM factory plug looks like this... Next part. I start to drive off without the original factory stereo plugged in and got about a mile down the road before it started dieing on me. I deduced that this truck must have some kind of security protection (I have no clue)…

Well, I usually stay away from all the local shops, there about 5. But I was bored so I went around yesterday to see whats new. Theres one shop thats actually pretty knowledgeable/cool. A old guy at Autosoundaddiction(VERN) We were sitting around talking, this kid comes in with a 15" Team RF fosgate(sweet SPL 4hp sub) the dustcap was loose, but he was sure it needed to be sent to the factory for "repairs" Tested the coils, their fine. Vern says " I have some CA glue in the back I'll just glue the dustcap back down and you'll be good, save you a couple hundred" The kids like no"I don't want it half assed, it needs all new parts." WOW I tried to tell him, that its jus…

Well I've been away from car audio atleast 2 to 3 years. Not sure what is new if anything. I've got a system right now. A single 10 inch re sx mated to a usamps md1d set to 1ohm so about 1000 watts. I'm actually looking to get rid of it and go more towards sq but know nothing towards that. What's a sq sub? Does it matter on amps? Box wise I know sealed box is best. I've seen these soundqubed and skar are they any good? Don't really have an idea on budget but as always cheaper is better and I'm looking to sell my system probably.

Do you have to charge the agm batteries or does it run off the alternator?

What are some general rules for box bracing i dont think i braced mine enough I have a 7.6 cube box with a fi btl and im just not sure

would it sound good to have 2 12" subs in a ported box and 1 10" in a sealed box. Would that sound good together.

Can anyone tell me how I can hook stuff up so I can play music through my laptop? My laptop has 1000's of songs from CD's and what not. Any receiver on the market can't top my laptop. Any way you could help me figure this out please do. Thanks, Jonathan

So...any stories??? i've set my friends alarm off<----wasn't bein an ass, just messin around. we once threw a kid in my trunk and i played test tones for like 5 mins. @40/50 vol. (w/superbass on) he was all ^^thats the funniest thing i've ever done relating to car audio.....

I'm looking for the best way to make the audio inside quieter on the outside. if that makes sense... I want to isolate the sound so with the windows up you cant hear the music playing inside as easily. Right now im trying to focus on the midrange as that seems to be the "worst". I currently have the midrange in the stock location with damp covering 95% of both door panels. Right now im building door pods but the midrange is still going to be IB so that should help somewhat but not as well as a sealed pod. Do you think adding second skin overkill to the outer door panel would help at all? any other ideas?

i was at work last month and what did I find in a junk drawer? A brand new digital converter box. I asked my boss what was the story with it. He told me that he and a coworker had bought it cheap in 2009 to use with a tv in the pharmacy and that I could have it. Win. I'm putting the box in my center console and buy an antenna to mount either on the back deck or near the front glass by the front defroster. anybody used one of theses in a car or RV while moving? I hear reception is crystal when parked and choppy like satellite during a storm while in motion, Thoughts?

Heres my status. I just sold the kove armageddon and the planet audio tt2250D that I had sitting around. I am in the process of selling my Planet Audio VX3002, and I will be ordering my Orion 2500D tomorrow. Once I sell the PA, I will order my 400.4. I also have some wheels on ebay so I can have some money to spend for christmas shopping. I am also about to buy a pair of EQT's for $115. Finals this week too. Fun stuff. Getting the car back hopefully friday or so. For those who don't know, I had a blowout and went off of the road messing up my axle shaft and a few body parts. The car has been in the damn shop for almost a month now. The dealership is absolutely pathetic. …

This is just something i have been wondering since i found out how a ported box works. I know that IB separates the front wave from the back. And I know that a port acts somewhat like another speaker above and at tuning. But what if you were to build a ported box, and seal off the port from the front wave entirely. like, the woofers face forward, and the port faces the trunk but you seal off the baffle from the trunk entirely. I googled it, but came up with nothing.

So can i run a Kinetik battery in the back of my car wiht no other upgrade? I mean i dont need an isolator or anything like that? Back in the day i had a stinger gell in the front and one in the back and had to run an isolator and was a pain in the ass. any help would be aprreciated, i got a civic with a tiny ass alt and i have a cap but i heard they dont help any and was wondering about running one of these batts in the back, thanks civicman07

If using an outboard EQ and a seperate outboard crossover, which should come first in the signal path? The EQ or the X-over?

i have 97 gmc yukon and i was wondering if anyone know where to get a good high output alternator for under 300. i would like it to be 250 amps

Hi again today ! I just want to know why so much people here run there amp at 1 ohms. Isn't it to hard for the car electrical system ? I have heard it is better to play at 4 ohms than 2, and 2 ohms is better than 1. What do you think, because I would like to buy an amp for my next sub. I need to choose between the DVC 1 or DVC 2 on a SSA Icon 15, and only after that, I will be able to pick a Sundown amp. Do you guys know how to have a good deal on a package sub + amp ? (SSA Icon 15 + Sundow, or other). Thanks for your help

Anybody ever ordered anything from here before? Its a store on ebay. I'm about to order my Zx750.1 from here and I was hoping for a little feedback.

Well first sorry for making a somewhat new thread, I thought it wasnt reasonable to keep my questions going on the Fi Technical zone. Maybe I can get more help here I have a problem which Im trying to solve. Basically, Im trying to set my gains right, however, I dont have DMM or O-Scope so I have to do it by ear. Pioneer TS-W3002D4 @ 2ohms 1k RMS 12" Sundown 2000D @ 2ohms 1k RMS Rockford Fosgate 4-gauge kit Factory HU using RCA with Line Output Converter. Stock amp, no Big 3 No Bass Boost on Amp. No Bass Boost on Headunit. Everything Flat.

So i read that in can causes fires as to why you must use a fuse but will it do anything else? Such as fry other electrical componets in your car?

Just bought another truck to mess around with and looking into doing a blowthrough. I figured if I'm doing a blowthrough I wanted to do 4 15s. I'm gonna purchase a h/o alt of course. My first option is 4 sundown sa 15s running off of a crescendo bc3500d or a sundown saz 2500d. Looking to only spend about $800 on the amp. Would the crescendo out do the saz for the same dollar pretty much? 2nd option was to get a lil louder. 4 sundown zv4 15s running off of 2 crescendo bc3500d or 2 saz 2500d. Or would that not be enough power to call it good? Would the much higher power subs My question is with the power I'm thinking of giving the 2 options what would be more ideal. I wa…

Okay so here are my plans new enclosure for my rebuild. Below is a picture of the single icon 12 I currently have and it's enclosure which is 14x14x34... 2.4 cubic feet. , tunned at 29.5.. I plan on adding a second 12. And building a Aero ported enclosure ..and the box specs also shown in the link below.. View Album, http://s1244.photobucket.com/user/jjzickowski1/library/box Now that box volume and tuning is what "I think" is ideal.... based on my desire to get louder and more SPL... but I am often wrong..this will be my first tunned enclosure build. So I have a few questions. Does anybody see anything that looks like a bad idea.? Those are the max…

o what could it be
