    whywhywhy. This post has to be the dumiest post I've seen in month. There are so many things wrong with your idea it makes me laugh.

    Just get a descent 4 channel amp and use your standard speakers. Then when you have money buy a sub/box and amp.

    Those logitechs may be high quality, but I can't imagine they'll sound good in the car. The first thought that comes to mind is the woofer. Since it'll be designed for home audio or use in a room it will not have anywhere near the sound quality of a normal car subwoofer. Think about it, it'll be in a trunk dude. Next thoughts and I believe this has been mentioned, but how the heck would you install computer speakers in a car and have them hidden from view. Anyways I'm eager to hear results so if you do it let us know how it turns out for ya.

    crosseye: i'd be very careful about wiring up a speaker set up like that inside a car. If you develop a fault and one of your speakers is shorted to chassis (if you were in a crash or something) your battery terminals might have mains voltage across them. If you're willing to take that sort of risk then go ahead, but please keep it in mind.

    Also, if that is a real 400W pure sine wave inverter and not a modified sine wave / square wave, i'd very much like to buy one because over here in Aussie land a pure sine wave inverter (like this one: http://www.altronics.com.au/cat.asp?...rp=27&id=M8022) costs about $450 for an entry level model, though i think over here we have much stricter regulations for any mains powered device..

    And you'll never get feedback buzz in a car system, because there's no microphone or input device where the signal could feed back.... :P

    I don't think this is an issue. There is a fuse on my power line at the positive battery terminal. Plus there is a fuse on the inverter. If the speaker lines shorted to the chassis I don't think much would happen to my car. The worst I foresee is the speakers' power supply or amp blowing.

    I'll check to see if these are still on sale, and verify that they are indeed pure sine wave inverters.

    I had no issues with feedback, buzz, hissing, etc when running it like this.

    There was a case here in Australia where someone was electrocuted because they wired up an inverter in a car to power a small fridge which developed a fault in an accident, and they somehow had mains voltage across their car battery. I'm not sure why their fuses didn't blow..

    Thanks..

    Ah, i was just pointing out that in someone else's post they described the noise as being feedback. It wouldn't be feedback as there's no microphone source to pick up the signal.

    I just got a super cheap 400W modified sine wave (MSW) inverter in from buying it off ebay. I tested using my Logitech z560s and it worked perfectly. There was no noise or interference or anything. I didn't have the speakers set up in the car, but just sitting outside. But the point was to see if they had a problem with a MSW inverter, and the answer is, they do not have a problem with a cheap MSW inverter.
    This is the inverter I purchased on ebay:

    (the cheapest I could find at the time that was Buy It Now)

    I really think you're going to regret using those in the car in the future. The subwoofer part is going to sound horrible in a car. Cars need 8-10" subs to sound nice, you're not going to notice the bass at all.

    I REALLY REALLY think you need to go with a 4-channel amp.
    Audio Rockford Fosgate: 900 Watt 4-channel amp, 501bd Mono amp
    Computer AMD 2400+ XP, 1 GB DDR RAM, Orbit Micro 250W DC-DC PSU

    Head units are for cheaters!
    sure some girls fake orgasms.....but it's guys like me who fake the whole relationship

    lgbr, you are a moron, did you even look up the Logitech z560s???
    Obviously you did not, because if you did, you would have noticed that the sub is 8"
    There is a 4 channel amplifier built into the speaker system
    I will notice the bass, because I can flood my dorm's hall with bass (that sounds good, unlike crap speakers) with these speakers
    I don't understand why you people don't comprehend what I'm doing here
    No I will not regret using these speakers, I will be laughing at all the people who spend 4x what I paid for a comparable sound system
    Also, everyone will be envious when they see the logitechs in my car

    PS I bet Q_gamelogic will post after me, and he's a moron too
    jeez, "never a good thing to call anyone a moron on forums" ??
    it's the f***ing internet! like anyone cares

    that SUB is long throw .... not SHORT .. look those terms up ..
    look up , you get what you pay for too ....


    im sure it wont sound HORRIBLE like you stock system maybe ... but not as good as a full blown car system...
