How to Bypass Relay on Sub Amp?

[synthsayer]

My subwoofer amp will not stay on. I have tried to bypass the relay switch but must not be doing it right.😕
Attached is the sub amp schematic and the Goodsky relay schematic.
Seems like it should be so simple... I have tried shorting across different points by the relay but the amp will still cut off. The power light stays green but that seems the only change.
I turn the amp off and wait a few minutes; turn it back on and get sound again.
Ughhh!!!! Please help???
Thanks in advance

Hi.

The relay is part of the protection circuit. It would be best to find why the protection circuit is activating the relay and put the fault right IMHO. Note A dc voltage across the ls for any length of time could cause a fire

Thanks for the safety warning.

Thanks for the safety warning.

When I short across one section of the relay the power light goes from green to orange, or from red to orange.

I used the same amp with another 4 ohm woofer and it worked properly.

???

Thanks again.

If the amp works properly with another speaker, then perhaps the original speaker is damaged in some way. The protection circuit senses the excess current demand of the damaged voice coil. Just a possibility.

I have tried the amp with 3 other speakers -both 4 and 8 ohm and the amp shuts off. THis happens when the sub amp is connected to Harman AVR 154 sub output.
When I connect the sub amp to a small Tascam TM-D1000 digital mixer the amp stays on. Using -10db outputs on mixer.
