Unhappy PCB with Chip Amplifier STK 4142II

I have Main PCB with STK 4142II, it is working,,,the problem is I have removed all the connections for tape, tuner, CD player. I get only main amp board together with power supply and speaker output.

This is Aiwa. At pcb board..it is Model No.AC-MX115A(Main PCB). I want to know where i will connect input signal. And what to do to power it on?

You have to search for the schematic diagram of the AIWA model no._____? and proceed as required.
The board model no. is of no use.
