yeah its a kitDo you know what the minimum voltage requirement is for the color organ to activate? And does it use SCR's (silicon controlled rectifier) or triacs to switch the AC? If you have access to the preamp output you may get better performance, but you may need to change a part. If this is a color organ kit, most come with 3 volt triacs. If you're trying to run more than ~200 watts of lighting you should replace it with a 6 volt triac. You may also need to upgrade the variable resistor that sets the sensitivity level to handle the higher output.
