Updates:
The Hertz 165's are installed with custom MDF adaptors while still utilizing the factory adaptor brackets.
I also got the floor deadened in the section under the seats and rearward. Closed Cell Foam (CCF) and Mass Loaded Vinyl (MLV) sheets is what I used here. The forward section of the floor has some factory vibration dampener and the floormats actually act as a sound deadener on their own as well so no need to do more there.
Before:
After:
I finished the door sound deadening which included CCF/MLF sheeting between the door card and the inner skin as well as some 3M Thinsulate Acoustic foam on the door card itself. I also utilized the Thinsulate Acoustic on pretty near every interior trim panel that had large air gaps behind it that could lead to buzzing sounds with bass and allow road noise in. This stuff is super light and extremely easy to work with. It also eliminates any chance of panel vibration from contact with other panels. It is actually used from the factory on several of the panels in small quantities and a thinner grade.
CCF Test fit:
Thinsulate Acoustic:
MLV hung on door:
Thinsulate Acoustic on trunk and interior panels:
I got the trunk finished up with CCF/MLF sheeting in the worst sections (bottom floor and back flat section).
Finally, I did some more work on my new Radar Detectors and other countermeasures installation which included a fused distribution block in the back for all my CM related accessories. The mounting platform I used for the MS8 provided a great spot for it.
Next steps:
The Tweeters have FINALLY shipped so once I get those and the Solen 91uF capacitors in (used to protect the tweeters from DC and any turn on pops, etc) then I can get them installed. The rear speakers (now going with the 3.5" DCX 87.3's) are still on back order, so it could be a while longer until those are done. My main gauge cluster hat is wrapped and on the way back so I can hopefully get that all back together soon at least.
A couple smaller items that need to be done are installing the time delay relay to turn on my CM board, finishing up some of the wiring for my new radar detectors and wiring in permanent USB charging/audio cables for the phones that I'll have in the car. Hoping to have everything finished up on spring break!
