I just opened the boxes for the HU and amp. Not so sure I can complete the install this weekend....
The HU outputs audio, to the amp, via RCA female connectors. The amp has RCA to receive, but also female. I gather that's normal, but news to me. So, I need a four short male/male RCA connectors.
Looks like I also need a mic to use handsfree calling. Makes sense, but I didn't realize that until I saw the back of the unit...
I'd like to connect everything to the back of the HU that I plan to use, or even might use so I won't need to access it again. Assuming I can get a replacement surround bezel, I'd prefer to not have to remove it again, and risk breaking it.
Oh, as Mike pointed-out to me earlier, if I want the ability to retract the antenna while keeping the unit on, I'll need a switch of some type. Also, it seems that the diversity antenna is lost too with a new HU. So, these two items will do the trick?

Filling-up the Amazon cart again... Thanks for the help.
EDIT/ADD: To connect to the cross-overs, I need those type of connectors too... I should have opened these boxes earlier.
