definitely, would be the easiest way. in the trunk, remove the left trim panel and you can clearly see the harness entering the amp. on the harness is the *thick" white wire - that's what you tap into. let me know if you need anymore help; i'm working on posting pics of my upgrade..cut and labelled every damn wire on that harness..seeing it in my sleep..
To see where we tapped into the factory harness. Yes, the wire is white, but there are several of them. You're probably going to have to test with a multimeter turning the key on/off unless you tap in right next to the wire blocks.
