So i just bought a Sirius tuner for my Alpine head unit and I'm just wondering about the power connection. I'm not sure if I should connect it to the constant 12V or should i connect it to the ignition 12V? I would just tap in to one or the other off the wire harness to my head unit. It doesn't say in the instructions so any help would be great!

 

BUMP

 

Why not just connect directly to the same pwer source as your headunit?

 

Thats what i want to do but im not sure if i should use the constant 12V or the ignition 12V.

 

Sorry, misunderstood you. Use the ignition 12V.

 

Thats kindda what I thought I should use. but i just wanted to make sure
Thanks alot man!
