    This forum is reserved for those users who are looking for the best sound possible. These users have different needs, wants, and desires from the rest of the users on this forum in regards to audio."

    this is the entrance title to this forum. if you read it, my questions were in the right place. dont call it a high end audio forum if it is for only p.c.'s. even if audio is all you want from you car pc. my question is why not just buy a nice deck that interfaces with your ipod like my kenwood? i control my ipod right through my deck never needing to touch my ipod at all. unless you guys have huge E penises the 160 gig would do most just fine.
    This Is a car-pc forum. So it is high-end along that side of the track. Also, the high-end section is a sub-section to a subforum of this COMPUTER-BASED forum. But to answer your question anyway...... Different people, different needs. With a pc you got way more options than with a deck of any kind. Besides that..... iPods (or whichever mp3-player you pick) and high-end is 2 things that don't go along

    Also you wont be getting good sound out of your ipod. The chips inside run off of such a low voltage to get the most out of that cruddy battery that the headroom is no where near the full human hearing spectrum. No matter how good your components are, your sound is only as good as the weakest link which is the iPod.

    But back to the point, this is a CarPC forum.

    but, is that not the point of a mp3. that is why they are so small in size. the conversion to mp3 from your original disc or recording takes out all sound frequencies that humans cant hear. unless you have the ears of a dog, you would never know the difference.

    and back to my point. were dose it state it is a car pc forum? it dose not. it simply states high quality audio.

    and even with a low voltage, the wire is so big out of the digital out (not the normal headphone jack, i am talking about the port out of the bottom of the ipod.) it would carry most electronic signals without much distortion at all. i am sure from reading else were in this forum, you still have to wire your pc to your deck in some way to get sound out of it. so whether you use an ipod or a pc the level of signal alteration is about the same.

    You might want to look for a car audio forum dedicated to just audio. This whole website is about car computers and this small section is about integrating the car PC with the audio part. Sticky right at the top of the page of this very subforum:

    Have Car Audio Specific Questions?

    IMO, the amount of power you have does not necessitate the use of a cap, and the extra batteries are good if you plan on jamming with car off but will put more strain on your alternator while the car is running. I've got over 2000Wrms divided up across my entire setup and I don't use caps or extra batteries.

    Not at all true. The actual rail to rail voltage of the audio processing chips in an ipod, is so small, that the normal human hearing spectrum is cut almost in half. So I am not talking about all frequencies, just from 20hz-20khz. They only go from around 100Hz to 10khz before the bandgap starts to degrade and there is noticeable distortion.

    Also the first few generations were bad, and the newest ones are worse with the best being around 5th gen for input response settliing. Send in a very small "blip" to the audio circuit, you should get a very small blip but bigger out ideally, and realistically you should get a sinusoidal hump that is very close to flat everywhere but the blip and then a sharp rise and a quick fall. Yeah that doesnt exist in the ipods. They take forever to settle, bouncing all around. And that is 1 blip. Now put in music which is millions of different blips and all you want is for it to become larger to play through speakers/headphones, but instead it is made larger, and there is random interferance adding or taking away parts of the wave that gets worse.

    And sorry to burst your bubble, but the headphone jack and the lineout jack are powered by the same circuit! Only difference is the output impedance they shove in there to drive different devices, and the output from both ports are pretty much equal.

    Now you dont have to wire a PC to a deck, you can go straight to a real amp. But the quality of sound is much much much much better even with onboard crappy chips like the AC'97. Reason? They have more headroom. Take a 5v supply, and you can swing your little audio signal anywhere you want without reason and no worries about wasting power because it is either plugged in, or in a device where the battery will last a long long time and is replaceable when it fails. Now put a device like the x-fi in the PC, and it is even better by a mile.

    So to sum up... ipod = crappy output nomatter the port

    well my bad. if you just go to mp3car.com, not the forums. there it is. but if you search anything on google about audio it seems to bring up this site allot. thats were i discovered the site. so i never, till now, went to there home page. sorry for that. but still if you do know anything about my problem would you lend a hand?

    by the way, wile you are using the digital out on the ipod it is being charged. thus boosting the ipods crap battery, with the one in your car.
