> u sure? i know the sockets are AC(we’ve plugged in subs to kill them into outlets directly), but i think the output OUT of a reciever in a speaker connection is DC. have you seen the amount of capacitors they cram into recievers?

Vot you should know this stuff!

House AC sockets are 120V 60Hz, say into a 4Ohm sub… that’s 30Amps… about 3600Watts. Most subs don’t like that :lol

The caps in an amp are for the power supply.

I dont have much time to go into why audio is AC, I actually have a lot to do today at work. Google it or better yet take a 9V battery and connect a speaker to it :lol
