Avic install

[Rex Ruby]

Not a ZR1 install but all C4's are the same inside!
I was thinking about upgrading the stereo in my 1993 but I’m a complete novice when it comes to audio. As I did my research and ultimately the installation I took the following pictures and write up to document the process. Hope it helps someone! I had put up a post or two asking some audio questions, did a fair amount of reading and called on some members the vette community that I knew had audio knowledge. This research got me to a basic understanding of what I wanted to accomplish. In putting my questions out there a forum member offered me an Avic D3 for free. Thanks TIM!

So I have a nice head unit, I decided to do 6X9 3 way speakers up front and 2 8” subs in the back. From looking at pictures of other C4 installations using 5.5” speakers, researching measurements of some 6X9s and taking apart the front speaker area to take measurements I felt I could make that work. Also my thoughts were the 3 way would give me mid and tweeter. I used the Rockford Forsgate RF R1693. Others had done 8” subs but I still checked the rear areas to make the 8” JBL GTO804 subs fit. I came across a free Alpine MRV100M for the subs. I used a Rockford Forsgate Prime R 150-2 to power the 6X9s.

Here’s the start, always disconnect the battery!
