 Noise from amp....

OK, frankly, I'm terrified, so I'm looking for some help/advice from the experts here... About a week ago, I noticed a little bit of static noise coming from one door in my car. It was only for a second while the signal was silent, and it went away once the music started. It only happened every few days at first. Now I hear it almost every time I start my car, before the music starts. It's definitely coming from the amp. I have switched inputs around and it comes from the same channel - channel one. Then I switched the outputs, and it came from the new speakers connected to channel one. My main concern here is, how much potential is there for damage to my speakers? And does this mean my amp's on it's last leg? It's an MB Quart Q4.150 pushing CDT components, so this isn't cheap stuff that's easily replaced.... Any help/advice is greatly appreciated!!

You probably had the amp mounted to a sub enclosure or something huh?
Ya I know, Jonny Bananas had his that way, and his is fine...
Did you set the xo and gain using a visual verification of the speakers mechanical reaction to a 150w channel?
No
Is this channel the problem on the speaker furthest from the amplifier?
Yes
Did the results of these 3 things provoke the speaker into a reactive manner that retarded the channel of the amp?
I haven't the foggiest idea what I am talking about.

It could be a few different things. Check the amp ground. When you swapped the rca's I hope you didn'tr hot swap them. meaning swapping them with the head unit powered. Are any of the rca's close to the power wire?

The ground seems to be as solid as ever. I had everything powered off when I swapped the rca's and the speaker outputs. The rca and power cables are on opposite sides of the car. The rca's run past the power side of this amp, but about two to three inches away and perpendicular to the power terminals. The strangest thing to me is that I've had this system up and running fine for 10 months before this noise started. I can post pictures of anything if that helps. Thank you for your input!

It shouldn't hurt the speakers. Do you by any chance have access to another amp? It sounds like you tried what i would have. And Lan is a good guy...Strange sense of humor though.

I sort of have access to another amp. By "amp" I mean a 10 year old Power Acoustik 4 channel that has been sitting in the garage for 5 years... Would there be any way to tell by looking at the board inside the amp in question? And just in case, any idea if it would be worth it to get it repaired or spend a few hundred bucks on a new amp if it is permanently damaged?

I would try the Power Acoustic and see what happens. If the noise goes away you know it's the amp. If it stays you narrow down the problem. If it's the amp....It might be worth getting fixed. You can't always tell by looking at the board if there's something wrong. Unless the thing goes up in smoke or you have a dead channel. Swap the amp and let me know what happens.
