sorry if you have already read this on my other thread....I'm panicking a bit at the moment!
crap...something just went awry with my system. I was listening to Kraftwerk (their most recent release), a record with a ton of sub-bass and highs but not too much in the mids, trying to break in the SR-6500's. I had my Alpine PDX-4.100 (channels 1 and 2) set at about 2 o'clock gain( I think that is 0.5v?) and my Pioneer p6900ub head unit with all settings flat and volume at 45-50 out of 62. There seemed to be no obvious clipping even with the midbass drivers working hard to pump out the electronic kick drums (it almost sounded like I had a sub!).
THen all of a sudden there was a very loud POP....and a pretty loud buzzing noise ensued. I turned everything off for a couple hours, and started the system again at low volume. The buzzing sound commenced as soon as the head unit powered on and only went away after turning it off. I tried turning the volume up slowly to see if the speakers were blown....but there seemed to be pretty much a full range signal coming through both tweeters and drivers...except the buzzing was actually as loud or louder, so I could not turn the volume up too high before the buzzing was unbearable. Then the popping sound hit again, so I quickly turned the head unit off again.
What the hell is going on?! I will begin troubleshooting tomorrow, but if this scenario sounds familiar to anyone, please fill me in! If I had blown a fuse either in my power chain or on the Alpine amp, there wouldn't have been any signal at all right? And if I had blown a tweeter or driver, there would be either no sound or very distorted sound right? So I'm thinking it might be either somethin to do with the head unit or the SR-6500 crossovers.
I rad that the crossovers' tweeter protection circuit causes a popping sound when it kicks in....is it a very loud one? Also, after it pops off, how long does it take for the tweeter to run normally? I hadn't read anything about buzzing though, relating to the protection circuit.
Can anyone shed some light on this before I go ripping my car apart for the umpteenth time searching for the problem?
