The concept is pretty simple. Tuner outputs connect to inputs on the preamp using common paired or stereo red/white analog interconnects often referred to as RCA or sometimes even phono or phone cord/plugs (obviously not all the correct term). Look for either tuner or aux inputs on the preamp.
Then the pream is connected to the amplifier using a similar stereo interconnect, going from the front left and right outputs of the preamp to the left/right inputs of the amplifier.
Your preamp should have a single subwoofer output that connects to your subs input using a similar but single interconnect.
Then simply connect power amp to speakers using common speaker wire, "zip cord", or whatever other name you may find attached to insulated multistrand 12 to 16 gage paired conductors.
Is that what you were looking for?
