Okay folks.
This is a friendly tip for all users!.
I watching a movie this weekend transformers 1 and yes i know terrible movie but i was bored. I notice the sound was all distorted,so i stop the movie to check all my connections even hdmi cables. They were all plug in right? will sort of,so i hit play and the sound was still distorted and so i yelled will you probably know what words i said i was frustrated.

Any how,i stop the movie again this time i check the actual speaker connections on the back of the speakers and guess what? they were loose and were not tide down tight!. I then twist the speaker connections on all speakers even the side surrounds and once again turning up the volume and hitting play distortion sound went away what you know loose connection.

So remember if you think your speakers got blown just make sure your speaker wires are tight and screwed down. But how do they come loose? when i haven't touch them since i install the speakers? i guess the vibration can do it?. But any how thought this was a nice tip to share.
