Home theatre system?

Question

ok.. whenever i play the system it starts off nice and loud...the crackles and goes to a very quite sound. then every once in a while they get loud then go back quite again without me even touching the volume...one person thinks the speakers are blopwn but i took them out and checked them and the didnt seem to be even close to being blown.....on slower parts of songs like the beginings and stuff the speakers work but once the singing or bass part comes they go back to that quite sound....

Answer 1

Check all you sound settings. Like if your in Surround mode with only two speakers.
