hi, i’m going to buy the k4003 stereo amplifier, but i would like to know something more. How many inputs does this amp have? is it only one input or are there two? I think there’s only one, and in that case, is it possible to connect RCA jacks to the amp so you can add a tuner or CD-player? If you can connect RCA jacks, can you tell me how to do this? Do you have a white RCA jack for the left speaker and a red RCA jack for the right speaker?
Hoping for a quick reply 
No, it has two inputs: left and right. You can buy female rca plugs for cable or chassis mounting, depending on how you wish to use the module. You connect these female rca plugs to the inputs by means of SHIELDED audio cable (see Velleman PUC2025 or similar).
Thanks a lot, your response was very useful
With 2 inputs, i meant 2 cd-players, but you’re right, it has 2 inputs 
Ah ok . In professional audio we do not count left and right we just count channels .
You can use a small mixer to combine your two cd-players or use an audio switch box. Linking the two outputs directly together is not good for sound quality.
Okay, thanks, i only need to cennect one cd player so i know what i have to know 
Perfect! Enjoy!
