You should not open them at all. No need for that. Just remove front cover, gently clean the parts beneath it with magic cloth and make sure not to press membrane. All that can be inside the box is some harmless dust and that can be vacuumed out trough the bass aperture but make sure to put vacuum cleaner on lowest suction. If covers are very dirty and made of plastic or metal you can wash them manually with dish detergent in warm water.

Right speaker terminal not working - tested out both speakers and they work fine when independently tested on the left speaker terminal. Sony MHC GX45 Shelf System, 2 speakers and 1 sub.


If the sound is also dead on that channel on a pair of headphones. Then you have probably lost the main power amp for that channel. To be certain. With you headphones on, slide or turn the balance control so you can only hear the faulty channel. With some music playing turn up the volume. If you can hear "faintly" music playing then the pre-amp is OK and the power amp has gone.
The power amp will be located on a heat sink. It will consist of 4 transistors (2 for each channel) or one big device (or two) (an IC). If it is transistors you only need to replace the two for the right channel.

Do these speakers work better with an amp? I am playing them now and they sound muffled using a regular shelf system


No models given, so a guess is what you get.

If your shelf system is not producing sufficient clean audio power you'll get distortion, which can kill a speaker faster than excessive clean power. Muffling is something else altogether. Are the tweeters working?

What cables do i need to connect 2 warfdale modus cube speakers to a samsung flat screen tv.there is a L/R output on tv.


These aren't self-powered so unless your TV has internal speaker amps, they won't work without an external device t amplify them. You would run the TV audio out RCA pair to THAT device, whatever it turns out to be.

I have a gpx hm3817dtblk and i cant find out how to get the bottom off so i can hang it on the wall?


On the bottom of the removeable base, you will see 2 rectangular openings, and inside these openings is a tab, that you lift up (it will seem like you are going to break it, no, its designed this way) lift those up, then slide base out. (We just spent twenty minutes trying to force the base off, then son took a pair of scissors and did this, figuring, well, if it breaks, then it will just have to always be hung on the wall) Good luck.

Amp keeps turnning off say to check speaker wires but speaker wires all ok i think


The amp turning off means you've got a shorted output, so I'd unplug your speakers, unplug the wires, etc, then plug it all back in, paying attention to the wires and where they're going.

The back plate is definitely snap off. As teodo mentioned, do not pull the entire rubber backing off. On the bottom and sides of the back plater there are two snaps, each directly on either side of the wider ridge along each edge. The top is a different problem. The snaps are on the speaker side and clip onto the bottom of the upper edge of the back panel. To remove the back plate: Start on the bottom of the speaker at the back edge. Pull away the rubber edge carefully to expose the joint between the back panel and the speaker box. Along the center of the of this joint on the panel is a wider ridge. Place a thin flat edged tool on one side of the ridge, pry, then push forcibly until the inner edge of the back plate is apart. Do this to each of the edges on the bottom and sides of the speaker. Don't peel away any rubber on the top side of the speaker. Press your flat edged tool into the joint and lift gently the back plate side of the joint before pushing it out. This will disengage the clips on that edge. If you're looking to replace the batteries, they are 3.5V 5200maH. Take Care

House already wired up for wall speakers (2 wires) BUT


Hi...
The 4 wires are 2 for the treble/midrange 2 for the bass.
You can tie the wires in parallel ( one wire from one pair to another in the other pair and repeat) but you need to know how many "ohms" the stereo can handle.
Should say on the back of the rack system
