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
