My factory HU does not come with Remote AC for amplifier.
I am planning to tap on the fuse box.
Problem is ACC (10amp fuse) is taken by the Car camera setup.
Can I use REM Remote power to tap on Cigarette lighter fuse (20amp)?

alternatively I am think of tapping on the ACC existing wire, by spitting and joining the 1 wire to 2 . Can?

Temporary solution now, I bypass/loop the REM with the amp power B+ , and added a switch to manually on and off amp for short term solution.

Thanks for suggestion. This way saves me trouble of getting a piggy back adaptor.
Would you know if theres any issue when fuse is 10 or 20amp? or as long as it is not below 10?
