VE Ute not cranking after powered sub install

[Splen20]

I’ve looked at other posts related to this but couldn’t find solution,

I’ve installed a powered sub to my ve ute hooked it up to battery and switched it off brown/yellow cable that goes into the stereo. When I turn the key over I get accessories but no cranking? I have checked all fuses related to ignition and battery tests fine..

Anyone know what the issue might be?

Check the disable links on the positive battery terminal.

Also, the subs direct power is fused at the battery yeah? Like, it’s not a unfused cable straight to the sub?
