    guys what is the reason of employing the capacitors at the input and output in this amplifier.
    can it take input from a TDA7000 receiver and amplify it ,i am asking this question because the output of TDA7000 is very low,so please help me guys.the schematic is here " http://www.flickr.com/photos/aj_silverthunder/4076214676/ " please assist me guys!!!! and those capacitor and resistor Cx and Rx ,what if i add them and what if i dont ,please tell me the result!!!!

    Have you got and read the data sheet for the TDA7000?

    ya i have read the datasheet,my doubt is, can the output from the TDA7000 is enough for the TDA2003 amplifier as input and will it amplify it efffeiciently.so please help me guys!

    Hello,

    The TDA2003 should be able to amplify the signal of a TDA7000.
    The TDA7000 has an AF output of about 75 mV.
    The sensitivity of the TDA2003 is about 55 mV for 6 Watts output.

    All can be found in their datasheets, just read them carefully.

    Greetings,
    Bertus
