1) Make sure the amp is properly connected to +12V power source. 2) Make sure the amp is grounded well, directly to metal - if you have a voltmeter, an easy way to check the first two is to see if there are 12 volts across the power and ground wires. 3) Make sure the speaker output wires aren't touching each other. If none of these are the case, there is an internal problem with the amp and it should be serviced or replaced.

If the amp is in protect mode, it probably has shorted output transistors.

What model amp is it?

If you power up the amp with the RCAs plugged in, does it go into protection mode.

If you power up the amp with the RCAs plugged in, does the woofer pop?

SOURCE: lanzar amp 1000 watt stays on protect mode

Hello snow11879,

I haven't been able to locate any support information online about your product, other than the email contact for support questions:

support@lanzar.com

If the amp stays in protect mode all of the time, I would suspect a short in the speaker wiring or speaker(s) voice coil(s), or perhaps a faulty ground. If it plays for a short period of time and then goes into protect mode, it is most likely overheating. First check all of the wiring. Test your speakers on a known good amp and make sure there are no places in your wiring where the insulation may have been damaged, causing an intermittent problem.

Many owners have reported that this particular amp has a tendency to overheat. Also, when run in bridged mode, the speaker impedance needs to be at least 4 ohms. It will overheat if the impedance is below 4 ohms.

Hope this helps.

The unit will need to be repaired by a technician. Most likely you have a bad transistor that is causing the protect mode to turn on. The only way to get the protect mode to turn off is to remove the bad part.

Hi monmax,
I hope you are aware that in bridged mode your amp will become monaural (single channel, double power). If you still wish to bridge it:
Switch of power.
Set mode switch behind amp to "bridge" position.
Connect speaker positive to CH1+ve terminal of amp output and connect speaker negative to CH2 +ve terminal.
Be aware that now, in bridged mode your amps output power delivery is 1100 watts for a 4 ohm speaker and 900 watts for an 8 ohm speaker. Make sure your speaker can handle that.
Peace
Jango.
