SOURCE: i have a crown ce 2000 watt amp. channel 2 keeps turning off

Do you get any Fault indications?

Have you swapped the speakers around to eliminate them as external causes?

When the channel dies is the unit very hot and is the fan turning very fast (it should be if hot)? The fan could be defective, slow or airflow may be restricted.

Turn the amp off and examine the fan guard on the rear to make sure it is clear of dust and debris. Vacuum it out if necessary. With a small thin non-metalic object reach in and test the fan for free movement by trying to rotate it. It should coast.

How do I connect a Sony xplod 1000 watt 2 channel amp to 1 10" dual 4 ohm voice coil 1500 watt planet audio subwoofer?


Connect one voice coil to one channel of the amp. Repeat with the other voice coil. Do not bridge the amp as your only choices would be series which would be an 8 ohm final load and cuts the amp power in half or parallel wiring which results in a 2 ohm load and very few Sony amps currently made can handle being bridged to a 2 ohm load.

My line 6 lowdown 750 keeps cutting out when i play a low b on my bass


Protective circuits kicking in. You may be overdriving the preamp to a clipping condition the amp sees as a problem. If it is under warranty, contact Line 6 and see if this is normal for this amp. It should not be, but you never can be sure.

Put new pa speakers in church 2 1000 watt tied 2gether and 2 300 watt. tied 2gether. the pa amp only has 250 watts with 6 mics connected and a cd player which plays fine. every time the mics are used if...


hi,
You have to check the ohms of the speakers all spekers should be 8 Ohms or above. if not it will overload the amplifier at high level. The minium ohms impedence of the amplifier is 4 ohms. If you connect two 8 ohms speakers together then the effective ohms will be 4 OHMS then the amp will handle the speakers. If you connect two 4 ohms spekers together then the effective ohms will be 2 Ohms, this will overload the amplifier. You will be able to connect two 8 ohms speaker to left channel or right channel of the amplifier. Check the speaker spesifiction to know its ohms. Make sure all the speakers have an impedence of 8 OHMS or above
OK

I have a Jensen A600HLX hooked up to Rockford 12 and it keeps getting hot and cutting off. I have it mounted on the top of the box. What is wrong?


MAKE SURE YOU HAVE A SOLID, STRONG GROUND CONNECTION BEFORE ANYTHING ELSE!!!!!
Make sure you are using the proper gauge wiring for your amp.


Is the amp set up in bridged mode? What is the impedance (Ohms) of the Rockford Fosgate 12? If the impedance of the speaker is different from the impedance for the amp in bridged mode, it WILL get hot and cut off. Also, if you overdrive the amp, the same will happen.

The amp is stable :
  • 75 watts RMS x 4 channels at 4 ohms
  • 100 watts RMS x 4 channels at 2 ohms
  • 200 watts RMS x 2 channels bridged at 4 ohms
  • 300 peak watts x 2 channels bridged at 4 ohms

  • Also, what model is the subwoofer? What are the specs? Is it single or dual voice coil?

    You can most likely mount a cooling fan on the amp and have it turn on using the remote sensor wire. If the amp still cuts out, you're overdriving it.

    Good luck and keep me informed!

    Alpine pdx 1.000 keeps cutting out


    You are going to want to make sure all your power wires and grounds are 4 gauge as well as the wire leads to and from the capacitor-4 gauge also. make sure you have a very good ground - the power wire from the battery should hit a distribution block-from the dist. block a 4 gauge should go to the capacitor another 4 gauge to the mono amp and another to the 4 channel amp -every component should have a good solid ground even if you have to bust out a grinder and a drill and some self tapping sheet metal screws and go nuts on it- see if that helps you

    you need more batt, more amps, try new batt, capacitors are paperweights, spend on good batt.

    Amp over heating and cutting off


    sounds like the Impedance of the speakers does not match that of the amp, therefore the output stage of the amp is trying to compensate, driving the amps too hard and eventually causing the thermal cut out to activate. Check the ratings on everything are compatible before you start sending it off to be fixed.

    Channel cut out


    Stereo Tech: Sounds like you definitly have a broken solder connection on the main PC board. A bad solder connection is tricky to find somtimes if one is not familiar with exactly what it looks like (kinda like mt st helens with a ring around the top) if you attempt this yourself DO NOT MAKE A SOLDER BRIDGE you will open pandoras box. Good luck
