SOURCE: sw 300 powered sub woofer

It sounds like your subwoofer acts as a receiver in its own right. Many low-budget home theater systems act this way, and it may in fact have a Dolby Pro Logic II encoder in it. Your best bet is to hook up either the speakers it came with, or purchase speakers from your local audio visual store. Check its power rating per speaker (in watts) in your manual, and purchase speakers that are rated for it.

The "red and white" input you mention are RCA connectors, and should allow you to connect a source to your system. If you have any more specific questions, please post them here.

SOURCE: amps and sub-woofer not working

Enter into the Audio Setup mode(press and hold volume button for at least 1 second). Next, repeatedly push the volume button until the display shows "2 ZONE". Make sure this feature is turned off. Hold the volume button again for at least 1 second to leave Audio Setup mode.

Now you need to make sure the Subwoofer Output is turned on. Do this by holding down(AM position) on the control knob(toggle stick) for at least 1 second. Each time the button is pressed, the Subwoofer Output is turned ON/OFF. the display should show "SW ON".

Next, you can go into Audio Control mode(press but do not hold volume button). Keep pressing on the volume knob until "Sub-WLevel" is displayed. Here you can adjust the amount of gain for the Subwoofer ranging from -15 to +15.

I hope this fixes your problem with it.

Cheers

SOURCE: amp light is on but no power to my subs!

Hi There.

When you say the 40 Amp fuse blew. Was it your mains battery fuse or was it the fuse on the amplifier? If it was the fuse on the amplifier then you may have hurt the amplifier. The Kenwood KAC-8101D is a 1000 Watt monoblock amplifier. Therefore if you say that 1 of your woofers is not playing, then it is almost certainly blown if you are sure it is connected correctly. Try disconnecting it and only running the woofer that tries to play. If this woofer is still working correctly, you will notice a drastic drop if the sound of your bass. The reason for this is because you have changed the impedance load on your amplifier due to the fact that the other woofer is not working. Have your working woofer checked and replace the faulty woofer then you should be banging again.

Hope this helps!!

I wired my dvc sub woofers to 4 ohms and bridged my pioneer gm-5400 amp and it cuts off when i turn the volume up.


1. Check if your power cable is of adequate Gauge 2. Try turning the volume down from the amplifier gain level 3. You could even check to see if your battery is on it's way out and just cant feed the amplifier with the power it needs. (very rare case) do the car lights dim when the volume is not really that loud? 4. There could be an error on the way the subs are connected, double check that you have absolutely configured them to run @ 4OHM. could be checked with a multimeter before connecting to the amplifier. 5. Another rare case is sometimes the fuse block expands when it heats up on loud volumes and can have contact issues so try tightening the socket that the fuse goes into. 6. It could also be a problem with one of the sub woofer or even the amplifier. more details might help me better understand the problem, but i hope this helps. dreamsystems

My subwoofer doesn't receive power, all amp fuses are fine, amp powers on, remote wire and rca wires are connected and intact. Before it stopped working all together the woofer would cut out and after...


If you are getting power to the amp, try this....Find a small speaker, unhook your sub and wire speaker to amp. Turn on your system at a low volume....If the other speaker is playing through amp, then your sub is shot.....If the small speaker doesnt work, then its either your channel is gone on the amp or the rcas have quit off off your head unit.

Car subwoofer just past half volume cuts off the amp


Assuming there is no short, or lose ground wire somewhere inside the box, diodes( in the amp) are fine, you might be overheating it by not allowing it to get good ventilation. This can be a big deal on some low end Chinese amps. Or the speakers are blown , or your Resistors (in the amp) are bad, but for arguments sake.
Most people don't use the proper size and or conductivity types of wiring, for pushing high amperage Think about it like this, Watts (power) =.Amps (energy) x Voltage (pressure) Resistance or Ohm's (amount) determines how much Wattage will go in or out, Ohms = Volts x2 / Watts.
What gauge wire are you using on your setup?

YAMAHA AV receiver RX-V861 I have the message 'Vol-fix' appearing on Zone 2 and no sound. This was working fine until then


Setting the RX-V861 remote control to operate Zone 2:
  1. Using a ballpoint pen or similar object and press the [CODE SET] button RX-V861 remote control. The[TRANSMIT INDICATOR]on the remote should flash twice.
  2. Using the [NUMERICAL KEY PAD] on the remote and key in 9992, the [TRANSMIT INDICATOR] should flash.
Assigning the receivers internal amp for Zone 2:
  1. Set the remote control selector to [AMP]. (Located to the right of the volume buttons on the Remote.).
  2. Press the [SET MENU]button on the remote control.
  3. Arrow down to Manual Setup and press the Enter button on the remote control.
  4. Arrow to the [SOUND MENU] option and press the [ENTER] button on the remote control.
  5. Arrow to Speaker Set and press the [ENTER] button on the remote control.
  6. Arrow to the EXTRA SP ASSIGN and select ZONE2
  7. Press the [RETURN] button on the remote control to exit out and return to the Manual Setup.
NOTES: There is an option for setting the Maximum Volume and Initial Volume in the Zone Set menu.
  • Max Volume: This is an optional feature but isrecommended to prevent the accidental change in volume levels thatcould damage the speakers and receiver.
  • Initial Volume: This is also a great feature that would seamlessly start the volume level for the second or third zone at the desired level.
We do not recommend using any Speaker Selector boxes to enable more than the recommended number of speakers per terminal.
Controlling Zone 2 using the RX-V861 remote control:
  1. If the Main Zone on the receiver is on, press the [POWER BUTTON]down and while holding that button down press the [PHONO]/[**] button on the remote. The [TRANSMIT INDICATOR] will light up.
  2. You will not be able to use the following buttons on the remote: (Pressing any other button will cause the remote to exit Zone 2 mode. [POWER], [STANDBY], [VOLUME], [MUTE] and the [INPUT SELECTOR] buttons [DVD], [CD], etc.)

My power pyramid sub is smoking i think its the jl 1000/1


If the sub is new, they need to be broken in.

All sub woofers need a break in period of about 5 to 6 hours at medium volume.
The reason is because the glue needs to be cured. This is done by the heat from working.

If you are giving it too much volume too soon, you are burning the glue.

Back off the subs and only play them at medium volume for about a week.

Speakers cut off when bass goes up...


it might be that your wires from your amp to your subs are too thin. since they were relatively new the first three months, they were probably undamaged, but after pushing them too much, they probably have broken wires, and can't get enough power to the subs when turned up, i suggest getting thicker wires before investing in a capacitor, it could save you money.
