Can you attack a Quad speed CD rom drive with the car battery and then attach the headphone output jack to the car speakers? This CD-drive has audio play/pause/advance/eject buttons on it. The CD-drive specifies this: +5V - 1.0A +12V - 1.5A I am not an 'electronics' guy - do the above specifications mean that the drive CAN be attached to the car battery? CAN the CD-rom drive actually play music satisfactorily from an audio-CD - how do u think it will handle the track skipping? Is any of this POSSIBLE? :) I would appreciate any help. :) Thanks in advance folks. Usman.

I'm not sure about the power conversion but I wouldn't do it if I were you. As far as the CD skipping, it WILL. Ther eare no dampeners like indash or changers have so you will get bad skipping from the player. ------------- Jeff

Thanks Jeff! But I have some questions - WHY wouldnt you do it? I thought it was pretty straightforward as the car battery is a 12 volt one. About the skipping question - isn't it even worth a try - to attach the CD drive and see if it works smoothly (without skipping) or not? 
Thank you for ur help! Usman.

I may be wrong, but I'm assuming you're talking about installing a CD_ROM drive for a desktop PC into your car, correct? If so, it definitely won't work for another reason besides the skipping problem. CD_ROM drives are equipped to translate the digital information they read from a disc into an analog audio signal. The computer takes the digital audio and processes it, sends it to the sound card, where it is then changed into sound. The way to make this work is to install a computer in the car to operate the CD drive and output sound. Not cost effective at all. I'd reconsider......maybe a AM/FM/CD radio or component CD player isn't so expensive in comparison. Dave CT Mobile Media

I'm sorry, typo. I meant to write "CD_ROM drives are not equipped to translate the digital information they read from a disc into an analog audio signal. ". Dave CT Mobile Media

If your talking about a computer cd rom like CTMobileMedia said there is no way it would work. With out the rest of the computer. The computer tells the cd rom what to do. The drive is not like a portable cd player where it can process information and send it to the output. The drive itself is just capable of reading the data while the computer processes it and then sends it to the soundcard and headphone jack.

I'd like to add - It also would need a +5v supply, which is going to be a trick to get ahold of, and then there's the fact that a car runs at 12v nominally - most cars usually run at about 13-15v when running. A cd-rom drive will want very clean, controlled powere - not like you get in a car. Your best bet is to go all out if you actually want a computer, or just a inexpensive headunit. BTW CTMobileMedia : Many cd rom drives DO have their own analog convertors in them, and have headphone (front) and line outs(rear) that go directly to the sound card and then out with almost no processing. ------------- /NyxBass

Wait! I just re-read the post!: "Can you attack a Quad speed CD rom drive with the car battery " Hell yes you can attack it with a car battery! In fact, I think I'd even pay to do that to a few choice drives from my past! Hmmm...old car battery vs broken cdrom drive...CRUNCH! :) ------------- /NyxBass

OK Nyx, I gotcha. Guess I'm mistaken. I was told that CD-ROM drives differ in that they lack the processing of a typical audio CD drive unit (ie - car radio or home stereo). Good point on the power supply. I think we all agree that Mirus would be creating more problems than he's solving by using the CD-ROM drive. Unless of course, you use an entire PC system and keep all your audio files on a HD and process everything with software (vs. 12V hardware). Yeah, that'd be cool.... just kidding. We already discussed this in another thread. Bad idea. Dave CT Mobile Media

Yes it would work, but it would only spin up to speed ie 12v. You would also need the 5v for the logic of the cd-rom and it should work ASSUMING the cd-rom has front panel buttons for play.

yeah the cdrom is a good option for cars too.... i have tried n tested it and it has worked satisfactorily, i.e. no skips n all.. now i want some one to give me wiring diagrams of kenwood cdchangers n kenwood head units. so that i can try it with my kenwood head unit too!! Utopia

You can do it, but you can't. blah blah blah...
Actually, if you are really serious about doing this, and wanna have something that is original by you. Go for it!! I did it once, and I loved it, but I didn't do just the Cd-rom.....I did the whole damn computer!! All you really need to do this is, a 12V to 120V converter ( hid mine in the glove box), a slim line case ( or equivalent), and a nice lil Bare bones kit from Tiger Direct. ( www.tigerdirect.com) just make sure the motherboard doesn't have on-board audio! you wanna get one of the new sound cards that support 5.1 or 6.1 sorround. ( the best thing about those is that you can make individual adjustments to the channels.). For the monitor, most of the new LCD screens for mobile theater can easily be adapted to a video card. Assemble the puter as you normally would....but the best part is you save some cash by not having to use the latest Operating System (OS). I'm sure you know someone who has win95 laying around. hide the case somewhere in the car.....or if you're feeling frisky, make your own case ( it sounds weird, but I know a guy who made a computer case completely outta legos!! I wouldn't recommend it for a car, but it goes to show, computer cases, like car audio has no limits!) All you might need is a lil fiberglass and/or plexi. Please note: you can get by with a P1 133 with 32megs of RAM and Win95 and a lil 3.2 GB Hard Drive.....in fact that's all I'd use..it's cheap!! After you got the case mounted and such hook the speakers up to the sound card, or the amplifiers to the sound card...however you're running them. Viola'!! you can use a CD-Rom drive and have the whole damn puter in your car.....The best part is....Not only can you play cd-roms, you got mp3's. and for those long and annoying stops in traffic, you gotta a video game system (emulators Guys!!! I play PS2 games on my lil machine)....and if you get a DVD-Rom drive you gots the movie part taken care of. Befriend a Computer Programmer, and someone killer in Electronics and car audio (if you yourself aren't any of the above), and the possibilites are endless. Just be picky on the CD and DVD drives....I think Pioneer makes a few for the puter, and they seem to handle up to the bumps.....Yes I have done this, and I love it....Plus I always gotta RTA with me!  I know this was long, but hopefully I helped some out, and gave ideas to others....Mobile Electronics: 1/4 knowledge, 1/4 theories and laws, 1/2 imagination!!!
