    Is it the wattage or the Amp I need to care about? I think, I need 12V / 20 amp power supply with regulated output for this amplifier. Do you think PSU can handle that?

    Power = Voltage x Current.
    The voltage is constant for most DC stuff like the amp at 12V
    So for a 20A amplifier at 12V you'll have 240 W in total that must be supplied by ur power supply, whether its a ATX psu, or AC-DC PSU.

    So, this will hopefully work as an alternative, I guess: http://cpc.farnell.com/PW01559/batte...onics-rs-25-12

    That unit does not have remotely enough power to drive the kenwood amp. Absolutely no way it could. If you were to go with the kenwood amp, u'll need at least 200W

    Just get a 100 watt amp and a 10 amp power supply. That's 120 watts, total. 100 watts is plenty for a kitchen install.

    ATX psu powering a car amp is overkill for a kitchen setup, in my opinion. It is going to take up alot of space and the wiring will be messy. Why not just get a decent set of computer speakers, like the Logitech z2300. The sub and satellite speakers are going to be much easier to hide. Or if you are more focused on quality, a cheap but high quality Sonic Impact T-Amp + set of bookshelf speakers will do just fine.

    I know, 100 watts should be enough, but I don't seem to find one. Any suggestion? Cheers!!!

    The problem with computer speakers is most of them are not wall mountable and I don't have the scope to use a separate sub-woofer. I did look for Sonic Impact T-Amp, but they don't seem to easily available in the UK anymore. If you happen to know one retailer, pls let me know. Cheers!!!

    the reason why i suggested the ATX psu is because its a relatively easy mod to do for under $50 and it gives you a lot of power.

    Yeah, I was discussing the various power source for my project to the guys (those who do that kind of stuff) at my Lab and it turned out that modified ATX PSU is the easiest, most cost efficient and the lightest solution. I'll keep you guys up to date. cheers!!!
