popping speakers - bought new receiver

I have a sony surround sound with polk speakers. It has worked very well for years. I had to take the system apart to move it because of construction in my home. I put it back together and now I have a popping in the speakers every so often. Last night one of my rear speakers popped pretty loud and a blinking light came on the amp that read "protected". Amy idea what could cause this? Oh, I found a loose wire on the rear speaker that popped. I fixed that but there is still a low pop on the speakers. Sometimes the left front, or the right front of one of the rear speakers.

Thanks for ya'll help

 

Not sure.. I think you should check your wiring again carefully, paying particular attention to any common grounding points.

The light coming on is a warning.. It's telling you that there is a fault in your wiring that is potentially dangerous for your amplifier.. Are you using speaker cables which are rated high enough for the current you are pushing through them?
I mention this because I once had an amp that would pop and cut in and out until you wound the volume up to a pretty high level. My external speaker wire was great, but inside the amp the cheapskates had used screened wire.. the same stuff as you use for signal cables, and it had deteriorated quite badly.. blackened in some places and the insulation melted in others.

 

check your speaker connection at the receiver make sure there is no wire shorting out even i strand of wire will cause this

 

I checked at lunch time and I found the ends of the wire connection on one of the front speakers was touching the connection next to it. On the rear speaker that pops, I found that the neg. connection was a little loose. I could tug on it and it came out of the spring connection. The wire I am using is the same wire I have been using for years. When I orgionally set it up, my buddy from down the street came to help and he told me to use the wire that I am presently using. He is an electronics buff but moved away. I checked the connections at the receiver and all looks tight. They are spring connections. I am at a loss.

 

another question - should the wire insulation be all the way in the spring connection are is it ok to see part of the unshielded wire sticking out from the connection?

 

Doesn't matter as long as the bare bits can't touch anything else.

 

Check along the entire length of the speaker wires, there may be a open spot in the casing of the wire, sometimes the wire can get twisted causing the positive and negative wires to come into contact with each other.

Good Luck

 

Hey guys - heres what I found over the weekend. Friday night, I took the speaker down that was popping. Saturday morning, I blew out the connections with my air compressor. I put the speaker back up and there was no more popping. Ok, that's great. Than I realized that there was no sound coming from the speaker so I thought it could be the wire. I went to the receiver and switched the wires from the left rear to the right rear (left rear was not working) and that speaker was working great. Than I tested the speaker volume and when it came to the left speaker, there was no volume. Than all of a sudden, the speaker was going on and off. There was no more popping. Sunday, I put the surround sound on all day and the speaker is working fine with no popping. I am still trying to figure what happened. My speakers are Polk M2 series and the receiver is a Sony.

 

Over the weekend, my speakers started popping again. The receiver went out and it flashed protection mode. Do you thing it is me receiver that is bad?

 

I would lean toward yes, the receiver is probaly causing the problem.
Take it to a shop and have them test it.
Without seeing it, it's very hard to say whats wrong.

Good Luck

 

I second Icanbe, most likely a bad receiver.

 

Speaker coupling capacitor breaking down anybody?

 

brasseaux, maybe you should try borrowing a receiver from a friend and see if the problem goes away.

 

A friend of mine said he would loan me his extra receiver today. Last night when I turned of my receiver, it went into protection mode as soon as it came on and will not get off of protection mode. I went to best buy last night andlooked at the Harman Kardon AVR-146 Is that a good replacement for my STR-DE635? What is HDMI?

Thanks - Frank

 

Eww, did you just ask what is HDMI?

I suggest you read up on that...

Try wiki for starters...

http://en.wikipedia.org/wiki/HDMI

But to put it plain and simple, it's an a/v connection in one cable.

 

@brasseaux

Here's a couple links for reviews on the Harmon Kardon unit, I think it would be a pretty decent replacement for the sony. Will probaly sound better also.

It looks like I will go with the Harman Kardon AVR-146. I looked on the back of it and there is one plugin for the subwoofer. On my subwoofer, there are two plug holes. On my old sony receiver, there were two plug holes for the subwoofer and I had lines coming out of both going into the subwoofer. How will that work on the new receiver with only one outlet? The only thing I am concerned about is will the 30 watts per channel be enough. Thanks - Frank

 

The two subwoofer outputs are probaly just for hooking up two subs.(not positive though)
I won't worry about the 30 watts a channel thing two much, you would be suprised how loud 30 watts rms can be.

Besides you can always take it back if your not happy, but I think you'll be more than happy with the Harmon unit.

Good Luck

 

I pulled up the owners manual on the harman kardon and in the setup it ask for the size speakers. I don't have any specs on my polk m3 series speakers. How do I answer this? I think they are 8 ohms

 

If they are floor standing speakers, you would answer "lagre", if they are bookshelf you would answer "small".

The speakers are more than likely 8ohms, possibly 6ohms, the receiver should be able to do both without a problem.
