https://www.audiforums.com/m_318162/tm.htmi just found a great thread on this topic, anyone else having problems similar to mine should definately check it out , thanks for all the help, i'm about to go give it another go, i'll let yall know how it turns out

 

I used the hood latch cable grommet. Just use some silicone sealant so you dont get wet carpet when it rains. I runnin 0 AWG through there and the interior so i guarentee you can run your cable with no prob. this is 1.8 though but the firewall looks pretty similar in both.

 

is that the one farthest to the right? i was thinkin about just using the ecu hole

 

try going through the grommet above the battery. youll have to take off a black trim piee uder the hood i think its 2 screws, cut the boot and your through... thats what i did, a little difficult to find the wire because it comes out behind the glove compartment but this orks the best. Another piece of advice would be to try run the RCA cables on the opposite side of the power cable-this will reduce satic and limit the possibility of alternator whine. Ive done my share of car stereo installs(use to own my own shop) so i know a couple tricks... Dont be afraid to ask... Happy holidays

 

alrightyy, well i got it through last night. i ran it in through the ecu box, it was pretty straightforward. and i ran the rca cables on the opposite side of the car to avoid interference issues, i'll try and post some pics

 

sounds good man look like your heading in the right direction
