    Class D amps are a good thing to look for when looking at this kind of power/ More complex, but far lower power dissipation.

    Yeah, but they are only suited to the lower frequencies, e.g. Sobwoofers.. thanx anyway.. I might look into it anyway.. use a high power class D for the woofers, and a smaller amp for teh mid/tweeters

    hmm..

    Seems to me that it would cost a lot more to build than to buy, considering how common high power car amps are...

    Not true at all these days. You can get some nice amps on a chip which are good quality class Ds.

    Can I just ask why you want an amp of this power? I used a 2k rig for a "Outdoor Concert" and go noise complains from the local town (5 miles away!) and that wasn't any where near full power.

    You do mean 1K rms don't you, or are you on about peak max power generated by some weird maths just to make the amp appear good to the unsupecting public.

    I can only think of a couple of speaker which can that this kind of abuse (JBL Concert 1s, and Sherman Commandos spring to mind), and they cost big time.

    and if your going to use speaker banks your better off amping each one seperately, if only from a weight point of view, (try carrying a 1K amp more than a few feet)

    And you say people actually pay money for M$ Windows?

    Total re-design underway: on the whole progress is very slow as the car is taking up too much time :)

    Are you trying to build a sound system for a concert or something?

    why do you need 1000w?

    are you listing the power like all the "mainstream" audio companies like sony, panasonic, technics...etc. they all list amp power as # of channels X watts/channel, so my 5.1 reciever with 100 watts per channel would be called a 600 watt reciever... if you are going to put 1000 w into 1 or 2 speakers get ready to shell out some cash for new stuff....

    if you want to look into some do-it-yourself audio i suggest
    www.diyaudio.com (definately look here)
    www.harmonicdiscord.com (kinda more of high end audio, than DIY)
    www.headwize.com(just headphone stuff but they have a lot of smaller projects)
    www.headfi.com (similar to headwize)

    do it yourself audio is very expensive, especially if you want clear sound... just look around at some of the sites i have listed. plus, i wonder if you are going to be able to get a good board layout for all the components you are going to need to put in this thing.

    also, try not to kill yourself when you wire up a multirail ~60V power supply the runs off mains supply. also, get a LOT of heat sinks for the IC's. they ARE going to get very hot!!!
