General Audio

Maybe this is super simple...but could someone maybe help me with this? how do you calculate square inches of a port? is it just LxW of your port? Ive built my share of boxes and never paid attention to this rule...Thanks guys!

Quick shirt trick, then a video showing some stuff blow around. I finished deadening my doors and had a ton of little pieces of paper in my car from the deadener so I figured Id turn it up and make a video. Yes I know its dark. Oh well. The second song sucks, It was just some song on the radio. The first video would be better but I was trying to hold the deck, control the volume, and shoot a video. So I decided Id just turn on the radio and shoot a video with whatever song was on.

Ok, I don't know anything about home audio to start out with, so keep that in mind with your responses please. Ok I have 2 RE, RE 12's (DVC 4ohm) and a pair of CDT EF-61 6.5" components (05 model) I would like to make a dorm room setup, yes to make matters worse, the signal is coming out of a COMPUTER. I have a M audio 5.1 sound card (http://www.newegg.com/Product/Product.asp?Item=N82E16829121122) This is the card if you are wondering. Ok, I am wondering what type of enclosure to put (I am thinking only one of the RE's) in. I can build anthing out of wood that I need to, just don't have much experience about the finer aspects of box building, but a wood shop is noth…

What is the correct wire harness for a 2006 lincoln navigator when adding a jvc kx-avx710

Im running my 2 channel planet audio anarchy 2600.2 amp with 2 pioneer 4 ohm dual voice coil subs TS-3002d4. The subs are wired to 1 ohm and im not sure what the amp reads it as when bridged. I wanna know if i should change the wiring of the subs or if i am safe the way it is. Safe meaning that i will not blow my amp. The amp's gain isnt up too much and the bass knob is about half. The subs sound really good when i play them but i just want to be sure i will not fry the amp. Any suggestions?

Well I am getting my first vehicle soon, and am building my first sound system in it. People who know me know when I do things, I go big and get the best available to me at the time. So I just bought a Team Cactus Sounds 7KW Amplifier. Now what should I hook it up to? Assume that I am doing the build in the bed of a pick up truck with either a 6.5 or 8 foot bed. What I am really wondering is should I go with many small(10-12") subs, a couple large(18") subs, or a single large(18"), a single medium(15"), and a couple small(10-12") subs? I realize with the last option, I would need quite a few amps, but lets assume that it isn't an issue. Right now I am thinking about wiri…

Well guys, as you have probaby noticed I havent been around much here lately (or anywhere on the net). Six months ago I took a promotion and helped start up a new division with the company I work for and it's been hectic to say the least. Well, it continues to be busy and I cannot devote the time to Acoustic Visions that it needs and with great sadness I'm giving everybody here a heads up that I'll be closing shop in a month when it comes time to renew my URL. I've been in business since early 2001 so it's been a good run and I've loved every minute of it and I want to thank you guys for everything you've done. My heart just isnt in to it any longer and I'm too tired afte…

I have a ported box built for a Rockford T2 12. It has a 2.25 net volume and is tuned at 40Hz (Termpro)...Actual in car is said to be 37Hz. I just ordered a new Fi Q 12 dual 1ohm and was wondering if it will work in my current box or do I need to change the tuning of the box?? How do you know how much to add or remove from the length of the port to get the Hz I'm looking for? I have attached a pic of the box that I have. Any help on this would be GREATLY APPRECIATED!!!

First of all this is the equipment ill be talking about. Rockford Fosgate 800.2 old school (the amp that is blowing fuses) Pyle Driver Plad413 (4 channel) Rockford Fosgate Punch HX2 (DVC, 4ohm) ok I wired my subs up for the 2 channel amp like it says to do here, http://a248.e.akamai.net/pix.crutchfield.com/ca/learningcenter/car/subwoofer_wiring/2DVC_4-ohm_2ch.jpg but that amp kept blowing fuses so in the meantime I am using the pyle 4 channel I bought to drive my regular speakers until the fosgate gets fixed. When i wired in the pyle I left the subs wired for a 2 channel amp but hooked them up to the amp like this http://a248.e.akamai.net/pix.crutchfield.com/ca/learning…

thanks to Rich for the box, Steve Miller at RD for the amp, and teamquickcelica (at caf.com) for the sub

i was just wondering, how important are TS specs really? i mean if a certain number is better that others wouldn't everyone shoot for that exact number? also why don't sub companies add specs like LE? thats a pretty important spec yet you have to look forever to find it.

I want to ground 0gauge to frame on my quad cab ram.. I dont want to ground to underseat bolts or any area from the inside of cab. The shortest length from mount to frame rail is 1.5 ft to inside cab. My idea was to have a bolt weldeld to frame closest to my wire entry to cab. Is 3or 4ft ok for a ground wire at zero gauge..

Well, I been stuck behind the newbs wall for the first couple post, but YAY, im FREE!! hehe. Anyways, Im looking for some advice about my next setup. I have most of the components picked out, but is open for discussion. Im into SQ and my breaking limits is $2k. All this will be going into a 2001 Lexus IS300. This is the list I came up with so far: HU : Eclipse AVN 5510 or 6610 ($450 - $550) Front : ID CTX65cs ($180) Rear : ID CTX65 ($160) Sub : Fi Q or Si Mag v4 (12") (Both price at $250) a little unsure about which to get Stage Amp : Cadence iA4 (owned it - got it for $200 ) Sub Amp : Saz 1000D ($280, if i get it by the end of the month) Wires : Knukonceptz + Rca & …

hmmm what could it possible be....? 2 TC3K's !!!!! top view, and a shot with the Orion 2500D, stupid UPS guy delivered the first sub, two diff. trucks...? WTF? 4 houses down the block???!?!?!?! good thing I saw him drive by and checked the awfully familiar looking sub crate box, with my name and address on it!!! anyway seems like things are finally starting to roll. Next, new 2-way alarm, tint.... then alt, wires... ect. cant wait!

So I found a place that's less than an hour away with a meter. So any tips/ tricks? What sweeps/tones should I take? Never been metered before so this will be an exciting experiance for me.

Alright, so I'm trying to plan out my car system and ive ordered my subs/amps. The subs are 1x 18" FI BTL and 2x 12" FI BTL's. I have a 4 door dodge stratus and I was planning on removing the back seats where I would put the 18" in a 7'-8' cu ported box. The two 12"s would go in the trunk area in a single ported box (can do two seperate boxes if that would be better). The trunk/cab would be connected due to the removal of the back seat. My question is, would this be a very stupid thing to do? Im VERY new at these things and I apologize if it's a rediculous idea. Also, if it isn't a good idea, what would be? And last, what would be good places to have the ports/woof…

I'm new at car audio and this is the first system I'm installing in my car. I'm hoping that some of you can answer my questions. I recently bought two Alpine Type R 10" subs and I was wondering if a MB Quart DSC 1500.1D amp will be able to power both of these subs. Also I'm looking for a good 2Din headunit that has navigation, bluetooth, usb, and dvd playback. I've been looking at a few online, but I'm lost when it comes to quality and good brands to look at. Also, are these headunit usually powerful enough to handle two Alpine Type R coaxial speakers or will I need an amp for those too? Any suggestions would be appreciated! My system I'm trying to put together is going t…

I am wanting to put 4 5x5 mid-bass driver under the back seats of my SUV. The question is, will a mounting board be sufficient or should I build an enclosure that'll fit nicely under the back seat?

Has anyone had any experience with RD Audio equipment? Are they a quality company? I had Mike , who is tied in with the company, build me an enclosure for my BTL and it is ridiculously nice. If that is any indication of the quality of the company i might have to look into some of their stuff
