Alpine HU Earth Question

[BRUN]

does not having the extra earth cable connected do anything ?

i mean does it make the unit any less powerful with it being 60Wx4 ?

does it mean the internal 'amp' wont be operational

It mean it wont work

If its an older unit then they need connetcted directly connected to an earth and i am sure the positives need hard-wired aswell

 

[BRUN]

my positive is hard wired but my earth is currently disconnected
