I recently got this PYLE PFA300 amp in the mail and i plug everything in and i plug the speaker in the positive and negative clip and trys to play audio through my aux an no sound so i switch to negative and negative still no sound then i switch to positive positive and my song plays through the speaker.

Quite weird here is a link to the manual i found online https://www.carid.com/images/pyle/amplifiers/pdf/pfa300-users-manual.pdf

OK so if i've understood you correctly your saying you get no output when wired like this:

but you do like this

aud1.jpg.91d7550513af12575e0e0068fd050bcd.jpg

 

 

If that is the case there is something very wrong with it

 

technicaly you could mix-up the "+" & "-" on each channel and get sound but "+" & "+" no way. if its new return it

send it back something is either not wired correctly in the device or something has shorted out
