Make sure the surround is off. Also, there is a setting on the remote that changes the volume on certain speakers. I think its 'CH.SELECT'. Just lower the front speaker and raise the center channel.

What ohm and watt speakers can I use with a craig CM402 cd am fm player? It came without them


Speaker requirements are likely to be 8 ohm, most modern hi-fi speakers are. A few low-fi systems have used special high impedance speakers and the old hi-fi standard for valve amplifiers was 15 ohm and 3 ohm or lower has been used in televisions a lot.

4 ohm speakers are commonly used where a higher power output is desired at the cost of some quality of sound reproduction but depending on how the sound is listened to can soon overload some amplifiers primarily designed for 8 ohm as it will try and deliver more power into the lower impedance speakers and perhaps exceed the rating.

8 ohms is a safer choice. The lower the wattage rating of the speakers the more efficiently they tend to be able to reproduce sound at low volume levels so for background music in a small domestic environment the average power requirement will be in the order of half a watt so even with a high powered amplifier the volume would rarely be turned up above 1 - 2 on the typical scale of 10 and ten watt speakers would be more than adequate. It is unfortunate that it is almost impossible to obtain quality speakers rated at such an unfashionably low power rating.

With the stiffer cones of a higher power rated speakers the volume has to be turned higher before the speakers become efficient and listening at low levels can be difficult. In a domestic environment a 50 watt rating is perhaps the best compromise as if there are neighbours to consider a ten watt average power output will be sufficient even if the amplifier is capable of higher powers. Just don't turn the volume up more than necessary.

The greater the power rating the more power will be required for efficient reproduction. For electrical and mechanical safety of the speakers the rating should exceed the maximum output of the amplifier but listening at low levels with quality of sound can become virtually impossible.

It is all a matter of taste and environment.

I ended up with one piece of a Teac model CD-X8 MIcro Hi Fi System. you can see what the whole system looks like at http://www.amazon.com/Remanufactured-CD-X8-Wall-Mountable-System-Subwoofer/dp/B000B65GV6...


Yes - you have the sub-woofer. It is a powered sub-woofer with a built in amplifier for both itself and a pair of small satellite speakers. Frankly, given the low cost of the whole system it may not be worth selling on ebay due to the high shipping costs of such an item, but I imagine you could get $30 for it or so on local craigslist or something, assuming you have no use for a sub-woofer...

My left speaker is loose


The symptom you are describing is exactly what is known as a "BLOWN" speaker or the voice coil has "shorted", this is caused from the volume being up to loud, heating up the voice coil and frying it, in the future if the bass/sound is distorted then turn the volume down just enough to stop the distortion and this will save the speaker.
As far as getting a replacement speaker, you will have to contact the manufacture to get a replacement.
Good Luck !

Hi, I have a rumbling noise coming from the sub woofer on my surround sound system. Any ideas?


Is it only at high volume or all the time? It could be that your input from your DVD may be bad.

My gpx karoke machine will not play at all power is on, shows cd number but no sound at all


Here are some things to try:
  1. Take the cd out, turn off the power, unplug the machine, plug it back in, turn on the power, put cd back in and try again.
  2. Check whether other cds play in it or if is it just this disc. Perhaps the disc is not compatible with the player. Might wanna check on that.
  3. Is the volume knob turned up?
  4. Does the mic work or is it just the cd? This will tell you if it is the disc or the machine that is not functioning properly.
  5. If no compatible disc works and the mic doesn't work and the volume is turned up, it "sounds" like the machine is defective.
Hope this helps. I'm a singer, so I wanna get you singing! Good luck.

My left speaker to my Sony HCD-GX450 stereo is


Make sure that Loudness switch is turned off & bass is not boasted up. Most cars have small cheap speakers that can't handle the bass. also its better to cut the low frequency from the woofer using a passive or active crossover. Most nowadays head units have got some sort of built in crossover. Refer to your head unit manual.

Harman Kardon go + play problem


Hi and welcome to FixYa,

Appreciate the direct "Ask Me".

Initially, pls try cleaning the battery terminals. In some instances, it may be necessary to scrape them to remove corrosion. Still there are times they may have to be bent or stretched to ensure that they provide more pressure to the batteries. Alternately, pls try to confirm that the AC adapter is working by checking for the presence of voltage on the plug/connector with the use of a voltmeter.

Should the above not address your concern, then it is most likely that the problem is internal electronics and the unit is simply going into protective mode. You then have a choice of performing a DIY (do-it-yourself) or seeking the services of a qualified professional.

Good luck and Thank you for using FixYa. Happy Holidays.

If the unit stays on at a low volume and cuts off when volume is raised, then fan motor maybe defective. If it cuts off no matter what volume level it's on then output IC maybe at fault.
