Added the cabling for the sub.. I ended up using epoxy putty only because I happen to have some laying around. Seems like it will work well.
Also started installing the amp. When I installed my boost gauge I had the foresight to run an 8ga cable from the battery compartment into the cabin at the same time... just left it coiled up behind the kick panel in the passenger footwell for a rainy day. Likewise when I installed my headunit I hooked up an RCA to the sub preamp and ran the remote turn-on - left it coiled around the base of the shifter.. Thanks Jay-From-The-Past.
I'm off work tomorrow so I should have it up and running at some point! Pretty excited to finish this one up and move on to the next project of installing some catch cans in the engine compartment.... That will be the last Z project for a while as we are moving into our first house in a couple of weeks and remodeling projects will take up most of my free time for a bit.
