    how to wire computer to car speakers??

    Hey guys,

    as you can tell by the post count, i'm new here!!

    let me start by saying visual basic is my friend and so is photoshop... I'm planning on writing my own interface to play mainly music and FM... if i feel like it, maybe add dvd, gps whatever in the future... but for now... mp3/FM that's all i want to do...

    With that said, how will i play the music in the speakers? will I need an amp? if speaker out on comp, to amp, and amp has all speaker wires wired into it?

    i'm not sure about this part...

    Thanks

    My general understanding of it is:

    Output from the PC to 3.5mm... convert that to RCAs, and run that to your inputs on the amp/amps. From there, you get speaker wire, and run that to your speakers on the opposite side of the car that you used to run the power for the amp/pc.

    Now, my only iffy part is on going from the PC to the Amp and keeping as high a sound quality as possible. PC generally outputs stereo 3.5mm... whereas amps input RCAs. There's a thread running right now discussing the best way of going about doing this: which audio cable option is better?


    Here's a guide that helped me when I was learning about amps: http://www.crutchfieldadvisor.com/le...mplifiers.html

    On the right you have the power connections, in the middle you have the speaker wire connections, and on the left you have the inputs.

    next question would then be....
    which amp do most people recommend? Something that's a good price... I'm not even looking for totally powerfull... anything above... i dunno... like 80 watts would be fine with me...

    but yeah, like the lilliput 7" screen which everyone recommends, is there an amp most recommended for our projects?

    What amp you use doesn't have anything to do with whether or not you have a PC setup. You need to choose your amp based on how much you want to invest into your car audio setup. I mean, you can spend anywhere from $100 to $10,000 on car audio, depending on the quality and amount of stuff you want and where you get it.


    How many speakers are you using, and are you putting in a sub?

    oh, heh cool then... in my car i curently have 4 speakers... I'd like to have an option to have a sub eventually... But for now it's strictly to replace my existing stereo setup with a pc system. Hence why i figure i wouldn't need a very strong amp.... I think my existing speakers and stereo is only like 15-20 watts... i'm not tooo sure... It's a 96 maxima. I was curious if theres a brand i should avoid more than others, or is an amp simply an amp, unless i'm looking for impecible quality?

    Oh, Thanks for the quick replies man

    If you're using stock speakers just go to best buy and get something cheap...stay away from that lighting audio stuff. Get a 4 channel amp that way you can hook all four speakers to one amp. Look for something in the range of 75-100watts rms. This is continuos power. Don't pay any attention to peak wattage as these are only bursts and aren't continuos. When you get your sub down the line you'll need another amp and you'll need to match it up based on the power requirements of the sub. Anymore questions just post up.

    hmmm very cool. Sounds good to me then.

    Curious, but would I notice a difference between a cheap amp and something of higher quality but with the same specs? I'm a total new to the amp world :-(

    I'll still get something of cheaper quality, since i'm not replacing my speakers for a little while... I'm don't need crazy amount of power, I just like listenning to music... lol, but i'm just curious...

    Thanks gain

    Ok. amps of less quality----they'll draw more power and give less power. So an alpine amp rated at 100rms will pull in less power to produce that 100, where as say a sony xplode with the same specs will pull in more power to produce that same amount. Also some amps will give you more options for controlling your output and this is something you want to look at when choosing the amp, that is if you have a few within the same spec range and price range. The list can go on and on, but this is the major difference. With your setup though I don't really think you'll have an issue. Now if you step it up a noctch then you may want to think about the set up more thoroughly, otherwise I wouldn't waste too much time worrying. Shop around and find you something within the range I gave earlier and you should be ok.

    Price determines the amount an amp gives off in heat vs. puts into use... basically, the efficiency. Also features like built-in crossfading, etc. And of course, brand name.

    But seriously... for your 4 stock speakers, you shouldn't worry too much. Go to your local BestBuy and explain to the car audio guy what you have and what you want. Just don't let him talk you into buying a 600watt x 4 channel amp for your <100watt speakers.

    "its a 96 maxima"

    Did it have a BOSE in it originally? If it was a bose, your speakers would have an amp on each speaker already, but I am not sure about the specs. If the car did not have a BOSE then disregard this and read all other posts
