I made wiring as it shows in the installation guide which followed the product. Yellow to fuse 27, Black - ground behind a glove box, Blue - 'connect remote line to the head unit' ( I made a connection to quad lock's red power cable). It is working fine like this just draining the battery (I think amp is not switching off). I was trying to connect to fuse No47 or 48 (15A fuse on the lower right hand side which was empty and has power from ignition), but amp is not working then.
