I intend on using a little integrated amplifier that has a USB input in order to add an MP3 feature to an existing receiver in a home system. It is PYLE PTAU23 MINI 2x40W STEREO POWER AMPLIFIER/USB, and I intend on not connecting any speakers to the amp, using in strictly as a way to play MP3 files, and connecting the REC OUT jacks to the receiver. I'm wondering if I need dummy 8ohm resistors on the speaker outputs, or is this not necessary?
