Hey, I have a Kenwood HTB-455 system, as soon as I got it I upgraded all the speaker wires to 16guage monster cable. I have a good monster coax cable from the DVD player to the receiver. Anyways, I find that when I turn it up to about 5 (max is 0) sometimes I hear a few pop's in certian movies. I am just wondering if this is normal, am I overworking the speakers? or could there be something wrong with my dvd player or something else in my setup? I was just wondering, those who own this system what do you turn it up to.
