i have the v.2-400 system with the upgraded control pod. I'm pretty good with not blasting it too much, cause let's face it, the sub kicks booty. i realized awhile ago that i'm getting a poping sound from the sub when playing a song with heavy bass parts. i can still play it pretty loud on most songs, but i can deff hear the diff in the system as opposed to when i got it. Also, occasionally one of my front speakers will go outrear one a couple of times), and i will hear static when the beat is hitting in the song, it usually goes away pretty quickly, usually.... ok, my questions are; 1)does the staic form the front speaker mean the amp is screwed up? 2)has anyone ever sent their sub to klipsch to get fixed, and if yes, how much was it and how long did it take? 3)did they fix it, or just give u a re-furb? 4) can u buy a new sub from them? 5)are the monster cables worth it? can uhear the diffrence? any help would be appreciated! THANX!!!!!
