ipod car dock rca

Car/Home audio question?
I have 4 channel kenwood amp. Its 60 watts rms per channel. I have it wired to 4 infinity reference speakers in my car. I want to put them in my dormroom for the schoolyear. How would i do this. I am getting an ipod dock with RCA outputs so im guessing ill treat that as my head unit and plug my RCA cables into there. I know i have to get an AC/DC converter and that i have to drop the voltage, but i dont know the best way to do this. Do the converters alter the current AND drop the voltage?? Would i just connect the amp power supply wire to the converter?? Anybody who has done this before or knows anything, please let me know. Thanks
The best way, in my opinion, would be to eliminate using the car amp and buy a home stereo receiver. The cost of buying a power supply to run the amp would be about as much as buying a stereo receiver. Your amp is 4 channels at 60 Watts per channel RMS. The fuse for that car amp is probably rated at 15 amps. The cost of a 12 Volt DC power supply rated at 15-20 amps is going to be more expensive than a cheap stereo receiver. Not only that, the car amp wants clean DC power. A power supply/converter will be somewhat noisy and that noise will probably heard through your speakers. With the stereo receiver, you are not limited to just your ipod. You will have a tuner and other inputs immediately available.
