thought I was immune to noise but ...
since day 1 I installed my system never had any noise whasoever. For the last few weeks I started hearing a little bit of high pitched noise coming from speakers. I thought it was more or less ok but... I also started hearing a very low frequency hum when I put the car in drive or reverse but once rpms go up a little and I start moving the low freq hum goes away. I thought it was my exhaust or something... and then when the engine is on and volume on the deck at zero I can clearly hear the subwoofer humming but not as loud as when the car is in drive or reverse. And I am not 100% sure on this one but I think I am hearing it randomly poping (not loud) a little bit when playing music. Weird stuff... I didn't start checking everything yet but how the f#$% would it appear all of a sudden?? I recently changed to a 12" ID sub running at 2ohm on alpine mrd-m605. I have a cheap line driver, maybe it is starting to go therefore bringing noise to the system. I thought I would never have to touch this stuff again and just enjoy the music but looks like that's not the case.
Anyway, did anybody have similar symptoms?

Go through your system cleaning all of the heavy cable points: amp grounds, battery connections, and make sure the battery is topped up (if it is a servicable type)

and now I'm screwed
well as I was driving yesterday I hear my speakers make scratching noise all of a sudden and then boom no sound, only the subwoofer going. I opened the trunk and noticed the ground cable came off the speaker amp (Alpine MRV-F540). It didn't really look like it coud've touched the positivie when it popped off. I turned it back on and sound is there and as a matter of fact the noise isn't there anymore as well. So I was happy and all that it was as simple as that. But.....
Here's the problem. I turn my deck volume up over 14 (out of 35 on an Alpine CDA-9857) and the amp goes into protect mode. The light turns red on it. I turn the volume down and sound is back and light is blue again. I noticed this is happening on lower volumes with songs that have more power to them. And when music is playing before shutting off it comes from all 4 channels.
Does my amp need repairing now? Is it blown?
