audio power reduction

i have a car cassete player with an output of 20w rms.I`d like to put the output of the player to a audio amplifier but the amplifie has no hight audio power input.So i need an "reductor" of audio power.Anyone has a schematic or a link to a site?
the variant with a resistor sucks because the signal is distorsionated

thanks

Resistors should work, but you will have to use a value near the speaker resistance ~ 8 Ohm to prevent distortion. Try to use a divider with 8.2 Ohms to 0.33 Ohms.

try with ina105. its a differential Amplifier. the Output you must design ~1 Vss and output resistance ~47Kohm. (with resistor divider it doesnt work.) :cry: :lol:
