[QUOTE="hemirunner426, post: 2753966, member: 574900"] Hello I am having an interesting popping/crack sound that is repeatable in my system. When playing Metallica - S&M - Master of puppets i will sometimes get a pop out of either speaker that i can rewind to over and over again. Low volume or high volume it is very evident. This only seems to happen when the deck is set to flat/ no MX or in otherwords... defeat on, which is where i normally play the deck. Enabling MX resolves the issue, so does changing the EQ to something i define... changing either or gets rid of the problem. The only thing i have changed is adding a HC-600 battery to help with my amplifiers power needs. Other then that the system has not been touched in almost 2 years. I noticed the problem a couple weeks ago before putting in the battery, however i wrote it off as being a poor quality MP3 (same song on MP3 disk)... but with the actual S&M disk and the new battery it is very evident and seems to be getting worse with defeat on. My gear is as follows: CDA-9853 MRP-F240 MRD-M301 2 Type R 6x9 1 Type S 10" 2ohm config HC-600 The deck is set to 2-way active crossover at 100hz and i believe 12db/octive slope(whatever the number 2 setting actually is) I am leaning torwards maybe the preamp in the deck is dying a slow death... or is it possible i have a ground issue? I would figure if its anything other then the deck, then adjusting MX and EQ settings will not fix the problems. Are there any ideas which i could try before i go out and get another deck? [/QUOTE]
