Car Audio? Answered

First off, this is a question about speakers sound quality loudness and all that stuff, it doesn't really have to do with any math or equations, just experience.  So I want some sub woofers, and after looking around I have determined that there are cheap ones, and very expensive ones.  Now, if I get a fairly affordable 15" (med quality) will it be louder/better than a 12" one that costs $900

Car Audio Kludge

I recently bought a used car. It has a radio, but no faceplate. While I could probably find a replacement faceplate or even install a new radio myself. I want to see if I might be able to DIY my own stereo out of the bits of my radio I do have and maybe an MP3 player or something. I figure the amplifier and power systems are all hanging out in the box there. So all thats actually missing is the part that acutally makes the audio to send to the amp. Anyone out there know enough about car stereo to confirm/deny my thoughts on this and maybe provide some advice?

car audio installation

So I have recently purchased an 8 inch subwoofer from a garage sale, wich was already mounted in the box. It has 2 inputs, a red and a black. I currently have it hooked up in replacement of the stock passenger side rear speaker in my 1999 ford ranger XLT, and it works well, but is not very loud. My question is 2-fold. 1: how would I go about wireing the speaker so that it could be used in addition to both the stock rear speakers without decreasing sound quality or volume, and 2: How could I increase the volume of just the subwoofer without affecting the other speakers? I have heard that there are "bass amplifiers" that i could hook in line but have not seen where I could purchase/ build one. Schematics and links would be very helpfull! Thanks, Iloveairsoftstuff

Bluetooth adapter for car audio

Dear all, I have a Skoda audio system integrated into my Skoda which has a cd reader plus a cd changer, but  only a CD button(no AUX available). I would like to stick inside the audio system a Bluetooth receiver so I can listen to music stored in my phone. The goal is to solder a Bluetooth receiver to the audio system without loosing the cd functionality. On top of that I would like to be able to change from one source to the other without having to use an external button like a 3PDT switch. Thanks in advance, Pedro

Car sound system?

Hello! I am new here. I want to know if i can connect this type of speakers ( http://m.jbl.com/products/GTO609C_JBL_US ) to this amplifier( http://www.sony.ro/electronics/amplificatoare-auto/xm-n502 ) or with this one ( http://m.jbl.com/products/GX-A3001_JBL_US?skuId=GX-A3001_JBL_US&searchMode=regularProductOnly&sCatId=cat140033 )? I want to mention that i want to buy two pairs of speakers. If no, what amplifier do i need (may i increase the impedance of the speakers instead of changing the amplifier?) Thank you!

car speakers troubleshoot

Ok, so my back speakers of my car aren't working properly... they were working good for a while but aren't as of today... I brought both of them inside and connected them to a household stereo and they both work perfectly in that scenario but one works a lot better than the other in the car. speaker A works well when it is place on either the driver side or the passenger side, speaker B sounds weak and tinny when on either the driver side or the passenger side... Please help me out, i've been racking my brain trying to figure out why they arent working correctly in my car when they play perfectly in my house... and they are car speakers not house speakers

PC speakers to car speakers?

Hi everyone, I am at a dilemma, I have 2 old PC stereo speakers, and since the rear set of speakers in my car are broken, I was thinking it was an easy transplant. However, when I took them apart, I saw that these speakers are 9V, and the car ones are (obviously) 12V, so I was thinking if it is going to fry them right away, or is it going to sing for some time and then fry them OR if it is going to be just fine. Also, these are a bit smaller (65mm in diameter) than the car's original ones, and since they are a generic brand and have no wattage rating inscribed on them, I am thinking that they require less W to power. Since the car ones are about 50W and my stereo can supply 4x50W, would that cause a problem one day if i uknowingly cranked up the volume, would that fry them aswell? I am not using anything big, just a simple stereo, with a simple output, no special equipment whatsoever. Thanks ahead everyone! EDIT: I just looked and found an inscription on the transformer in the back of the main speaker: I/P 240V ~50Hz O/P 9V ~500mA That gives me like, what 4.5W? Is that each or altogether? I am thinking these are too old/weak for this :o

Car Battery Powered Portable Audio Cooler?

Ever since i've seen this portable audio cooler, ( www.addictronics.com/projects/stereo-cooler ), I've always wanted to make one. But unfortunately the person who posted the article never clearly had instructions posted on the blog. I've been looking around for a long time, and have not found other sites that have decent enough instructions to follow along. It has to be able to be powered through a car battery, and the speakers will have to be directly powered through an amplifier or right through the car stereo. I have the specific model of stereo in which i plan to use, and it had a 10 CD changer with it. But I want to use the Radio on its own, as well as somehow wire an RCA cable to it, for use with iPods or other mp3 players. I believe the model is     [  KE-2303QR  SUPERTUNER  ]

how to wire an amp from the rear speakers of my car?

I have an oem navigation cd/dvd radio head unit in my 05 Dodge Magnum that I just installed and I want to wire in an amplifier and run a 12" or 2 10" Subs with the existing system. I was fortunate enough to grab the ear of a tech that works at the local Dodge Jeep dealership and asked him what I needed to do and he said that at the dealership they tap off the rear speakers a piece of equipment that they can then hook up an amp to. Does anyone know what piece of equipment he was talking about?

What potentiometer to use as audio control in car stereo?

Hello all I am working on installing a tablet into my car instead of the original head unit. But since the tablet will be permanently mounted inside the dash, I have no way of turning the volume up or down on the tablet, therefore I need to install a potentiometer into the audio cable that goes into my amplifier.  I have tried with a dual LIN 100kOhm potentiometer, which worked to an extend, but not as well as I had hoped.  It did turn the volume up and down, but it couldn't turn the volume all the way down as I had hoped it would be able to. I just want it to be able to turn up quite loud, but also turn all the way down, so I don't have to pause the music everytime I want it to be quiet.  Cheers! Mathew

Can the male end of an iPod dock connector be adapted or spliced to take in plain 3.5mm audio input? Answered

I'm aware that this might not work on the technical level but I'm willing to try it. I've got a car stereo that I've used for about 8 years and it works fine. It uses a proprietary cable (Alpine), kind of like this (http://ak.buy.com/PI/0/350/203086658.jpg). It plugs into my iPod that closes up in the glove compartment and then it allows me to select artists and change tracks through the knob / buttons on the face. Since this stereo deck doesn't have any other inputs, I was wondering if I could build a cable to accept audio coming out of my cell phone or any other device. I know that the 30-pin iPod dock connector has various lines for power, data, audio, etc. and I was wondering if anyone has experience with this. Maybe I could split the wire in half or get an adaptor with a female iPod plug to a male 3.5mm adaptor. I've tried Googling these things but it's too hard to describe what I want in keywords.

How to wire a new head unit in my car?

I just got a new car (04 Sebring Touring Sedan) a week or two ago and i've decided that the stock stereo doesn't do what i want. So i bought a Pioneer DEH-1300MP online. Then it didn't come with a wiring harness so i got one from ebay that fits. Anyways.. my question is how i would go about connecting the new harness to the old one so i can install the new deck. Here's a wiring diagram if that helps.. http://i55.tinypic.com/2054ksx.jpg (the new harness is on the left and the old one is on the right) I tried pairing up what i thought went together, can anybody confirm/deny it?

How to connect 2 audio sources to one speaker?

Hello, I'd really appreicate if someone could help me out here. I have a Samsung Bluetooth Car Kit which outputs the sound though a seperate speaker. What i'm looking to do is connect it in some way to the cars owm drivers door speaker. The Head unit mutes automatically when a call comes so there would be no sound going to the speaker from it when a call was in progress. The simple way to do it in my eyes would be to just connect both sets of speaker wires to the one door speaker, but i'm concerned that the 50w RMS that the head unit can blast out would be feed back into the bluetooth control unit would in some way damage it, and vice versa when I was talking on the phone. What could I use to prevent the sound getting feed back, some type of diode or something? Like I said any help would be really appreicated as the speaker is a big ugly thing which I'd rather not use if possible. Thanks Davy

proximity car key ??

Ok so I work at a car audio shop as an installer and I see so much different stuff and do a lot of custom stuff on cars.. Ive seen a lot of cars that are keyless.. its just a key fob. when you have the fob in your pocket the car knows you are there and lets you start the car with a push button... that stuff is at least 5 years old.. now the other day a new z07 corvette came in for work and the guy handed me a fob to bring it in the shop,, nothing new at first,, but as I approached the car I heard the locks click,, so I stopped and walked back a few feet and I heard them click again... this thing is unlocking and locking on its own as I get near and away from it... And it still gets better.. after walking to and from it a few times to confirm my suspension I finally opened the door... the dash was flashing and it said welcome technician. the key I had was a valet key.. the other key fob I had welcomed the owner by name... this is really cool... I needed both fobs because I was putting a remote starter on the car and both keys are required to program it.. the valet key I had also turned on the traction control and the car wouldn't go over 40 mph... that's a lot from just a key fob... NOW FOR MY QUESTION HERE.... Is this done with rfid or some sort of proximity sensor on the fobs?? I want to build one for my car but just for the locks and push button starter... but I want to retain the factory key also..any ideas or maybe a link to an instructable?? ive searched them but cant find one for my purpose.. lots of rfid stuff though..

A Homemade Bluetooth Speaker using an extra car speaker?

Okay fellow instructables friends, here's the deal.  1) I don't really want to pay $50 for a bluetooth speaker.  2) I ended up with an extra 5 1/4" speaker due to one being dysfunctional out of the box and the company sending me replacements.  3) I've got a basic background in electronics projects, but am by no means an expert.  That's the gist of it. I've seen some bluetooth/FM/USB modules on DealExtreme that looked worth getting (around $14), but I'm not so sure of the Audio amplifier circuitry and whatnot. I figure I can figure out an enclosure and whatnot, but does anyone have any expertise/knowledge about the mixer and amplifier stuff? Can they be salvaged from other thrift store finds perchance? Look forward to the answers! Thanks!

'02 Prius: Create AUX audio input

My Prius is still cruising along fine. But, I tire of messing around with FM transmitters to get my audio into the radio/audio system.

No thanks.]I see all the newer cars with an AUX audio input jack. I'd like to put in such and/or a Bluetooth input.I went to a local car audio store and they said $450 to add it in.

Is it possible to use a old mobile as a bluetooth audio receiver?

I have seen several tutorials outlining use of old mobile as an mp3 player especially hook it up with an car audio player (via aux in port). I have a sony ericsson w700i walkman cell phone lying with me. I already am using it as an mp3 player in the car. I wanted to know if i can extend its use further and pair it with my new mobile to play music wireless. If it's possible it might well be used for making receiving calls via car audio too. I know there are several cheap stereo bluetooth receivers out there which can be used for the same purpose but I am interested in knowing if an old mobile can be used for this purpose somehow or not.

How can I make a filter in the audiocable between my laptop and car stereo to avoid the noise I now get.? Answered

When I connect my laptop to my car stereo  I get a lot of noise. I suspect there is some kind of loop between the laptop power supply and the amplifier.

iPod Cassette Adapter Help?

Hey so I used to use a $30 Dynex Cassette adapter to play my iPod in my tape deck. My deck is a Pioneer KEH-P1010. Anyway, it was a real pain to get it going at first, but then it worked perfectly. I broke the adapter and so I decided to buy a cheap-o $5 "iWorld Cassette Adapter". The three instructions are (literally): 1 - Place the cassette into your car's cassette player. 2 - Insert the audio plug into your iPod®/MP3's headphone jack. 3 - Press play and enjoy your music. Sounds simple enough, right? I've tried it numerous times with my iPod Touch 64gb (same iPod as with the previous adapter) along with my mom's iPod Nano (the newer generation from last year), putting the cassette in both ways (text facing up and down). Each time I try, I can hear the deck spinning as it tries to read the cassette (with a "(---)" flashing on the display), but it always kicks back to the radio. Any thoughts on why this happens or how I can get it to work? A friend of mine had bought the same model (from the same store) and said it worked great (hence my purchasing of it), so I'm sure it should work on some level.

Should I put sound deadening/dampening material in my car?

I've just spend a little over a grand and blown the majority of my budget on new speakers amp wiring and a headunit for my car. I haven't bought any subwoofers. I'm happy to go over this budget if sound deadening will make a large difference. Anyway, I was just wondering- road noise and all of that aside, will sound deadening make my stereo sound noticeably better? As in, sound quality alone Should point out that the speakers are 300 watts rms all up. 6.5" "woofer" 4" midrange and a tweeter that's under an inch each side. Thanks heaps!

Trying to create my own car head unit.. Sorta.

So i enjoy electronics, so i thought of an idea that would really benefit my life. I enjoy listening to music in the car. Like really enjoy it. Currently i have the original head unit that came with the ford focus mk1. Its terrible, and the speakers distort at loud volumes. Plus there is no way currently for me to listen to my own music apart from a CD. Which come on.. no one uses anymore.So here's my idea that im finding difficult to bring to light. I was hoping i could create some sort of botch head unit. But i want to create this using components that are not end products. So no i do not want a £100+ amp that does this for me without the DIY. It should be a lot cheaper to do this DIY.So my idea was 1 amplifier circuit board, which is difficult to find to power 4, 4 Ohm speakers. So my idea was to have 4 separate amplifiers for each speaker. I can't find a single channel amplifier to power a 4 Ohm speaker however. The signal the amplifiers would receive would be through an auxiliary cable or bluetooth reciever.Any ideas to point me in the right direction would be awesome. If there's a loophole in my idea then please let me know. Still a lot to learn, but that's what were here for right.Thanks in advance.

Is it possible to DIY an ipod car adapter. (one of the ones that plays through the cars radio)

If you're not sure what i mean, It takes the ipods audio signal and broadcasts on a radio frequency that is then picked up by the car and played through the cars sound system. I really would like one but dont want to pay $50 Some note: -I have a limited but understanding knowledge of electronics and can learn new concepts easily -It would be best if this could be made from parts from around the house as i tend to have a limited supply to electronic components (i do have access to old machines like printers and an old computer tower and then a bunch more that i can scrap for parts) Also, I could probably find an old radio somewhere as im sure that would help
