maybe you have not install a sound card in your system. the device that attaches to the PCI slot on a motherboard for the computer to input, process, and for you to hear a sound from your speaker.
If there is no sound and there is no light, then it is an electrical power problem. Make sure all the wires are connected and make sure the it is still plugged into the wall. Maybe change sockets see if that helps. If none of that works, then something died and cannot provide you with power any longer.
I hope it's working.
The job of a battery is to power the torch. if the circuit is not complete then the bulb wont light up and if the batteries arent the right way round the bulb wont light up either.
A number of things. Is the audio cable plugged into the green jack tightly? Is the power pack plugged into the wall and into the speakers? Is the "volume" control on your computer muted or turned all the way down? Is the sound card working properly? Good luck.
Speakers generally work when they are connected to the radio and not shorted out. You can test the terminals with a multimeter to see if its getting power.
You can power two 400W speakers if you have Peavey PV115 using a 2000W power.
If the left light on your Pintara has stopped working, but the globes and fuses are okay, the wire may have a problem which causes it to lose power. To determine the problem, trace the wire to check for a break.
You are having fan belt problems.
That would be short for "generator" light. If that light is on while the engine is running, the charging system is not working and you are running off of battery power only.
Ohms is a measurement of resistance between the amp and speakers. Most home audio is 8 ohm, if you run 4 or 6 ohm speakers you cut resistance down and get more power out of the amp. Say your stereo is 100X2 @ 8ohm, if you use 4 ohm speakers you should get 50% more power BUT the amp is working twice as hard and can burn up.
they depend on the tide and arent very realible
There arent any.
The output power of home theater speakers can vary by a significant amount depending on which speakers are owned. It can range from 30 watts to 150 watts.
