Install Car Alarm "FIRST" or Car Audio?

Question

Alright so i'm not very sure whether i should install a car alarm or an audio system FIRST... The thing im confused about is the wiring.

Do either of these effect each other in the process of installing one another? or is the wiring to both in totally different places that they won't come in contact if i choose to do one over the other first?

PLEASE REPLY!

Answer 1

Separate wiring, doesnt really matter which one you do first.  

Answer 2

neither will effect one another.... go alarm first... always protect your stuff, and your ride... getting sounds first can tap you out of cash fast, then you will be pushing off your alarm
