Hello!

I own a 2018 Altima SL and am trying to run power wires to the trunk. Just a red and a black for a radio installation. I have seen a few posts about the "grommet" be hind the D/S inner fender. It seems there is quite a bit of sound deadening material in the car (on the inside) is this an SL thing? I'm trying to be as unobtrusive as possible but it looks like I may have to do some hacking on the deadening material. I have not peeled up the carpet at all yet. Another question: seems there is a wire tie of some sort on the grommet, is there one on the inside, outside or both?

Also, would it be easier to remove the airbox as well?

thank you!
Bill
