shared power , ground wire

Hi,

I am currently in the progress of adding an indash monitor to my car alongside my Headunit.

I wanted to ask if there would be any issues caused by splicing it into the same power and ground wires currently connected to my head unit?

I have tried searching through the forum for the answer to this, but I could not find anything.

Both headunit and monitor have fuses on their power lines, is this enough to protect them?
Also, if I connect both the head unit and monitor to the same ground wire will I get noise/interference?

Basic picture of what I mean:

No, you'll be fine.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

thank you for the quick reply, and sorry if its a stupid question.

So there wont be a ground loop caused by having the two grounds connected?

No. That's not what a ground loop is. A ground loop is caused when there is a lower return resistance between electronic devices OVER THE SIGNAL cable, causing the introduction of noise. You aren't doing anything remotely close to anything that could cause a ground loop. You are creating a STAR ground, and is preferred to multiple grounding points.

Interesting article regarding ground loops...
