I have recently installed JL Audio c2 350x & 525x in my '03 Z. The sound is better than stock but now I want to upgrade the head unit. I am not ready for the double din bezel, touch screen, amp and sub yet so I'm thinking an Alpine CDE-172 BT with a Maptech faceplate. The Bose woofers are still functional in the doors. Has anyone done this same setup and are you happy with results? Is there anything else that I need. Any pics of single din installs would be appreciated. Thanks in advance. Save the wave.🇺🇸

you'll see some with custom lettering on the kit, but not sure if those are available anymore.
I did that when I had my C5 and it was a good improvement. Especially with added features such as BT and MP3 playback via USB.

@glfrmrk So you recently upgraded your speakers and now want to upgrade your HU with a single DIN and a Maptech faceplate
You will need an interface to properly replace the OEM headunit, keeping the rest of the system intact. This interface is not a simple wiring harness, and it is needed because the C5 Bose system doesn't use standard signals.
This system is based on a modified Delco head-unit, a Bose DSP box and subwoofer amps that use pseudo-differential low level signals along with fully differential speaker level signals. The common signals are not standard and have a DC offset, so they cannot be grounded.
The 2 most commonly used interfaces are:
AXXESS XSVI-2004
PAC AUDIO ROEM-VET1
Either one will perform well when correctly installed, although the Axxess offers better system integration as a result of interfacing with the Serial Data Bus. That's why the difference in price.
interfaces with the Serial Data Bus, in addition to preserving the Retained Accessory Power (RAP) feature, it does not need an external "Accessory" switched power connection.
doesn't interface with the Serial Data Bus, it doesn't preserve RAP and requires the extra switched connection mentioned above. The headunit's OEM harness lacks this connection, but it can be easily brought from an unused harness (except '04) in the passenger's footwell that has 3 wires (yellow: switched via Fuse 11, orange: always hot via Fuse 7 and black: ground).
The Retained Accessory Power (RAP) Feature allows the radio to continue playing for approximately 10 min or until a door is opened, whichever happens first, after the ignition switch is turned off.
These adapters take care of all necessary interfacing and make the process plug-and-play, while preserving the OEM wiring.
Here is a diagram showing a replaced headunit while keeping the rest of the system intact (the diagram is the same for AXXESS or PAC adapters).
If I remember well, the Maptech face plate includes the installation kit.
The lettering can be above or below the head unit opening, there is also a non illuminated version with the head unit located in the center of the mount.
The main lettering illumination available in red, blue, green, yellow, white LED’s and also red mini lamp illumination.
Thank you GCG! Do you know if there is room behind/on top of the Alpine head unit for an Alpine KTP-445A amp? Would that amp drive the four twiddlers?
You should be able to accommodate it
Yes, it will handle the 4 twiddlers. It's plug-and-play and it is just inserted between the new Alpine headunit and the required adapting interface I mentioned in my previous post.
Since the Bose sub woofers have their own amp is there a way to use the Alpine amp to provide the additional power only the JL Audio speakers or do I have to remove the Bose amps from the subs and let the Alpine amp provide power to all six speakers? Or remove the subs entirely?

The Alpine amp, is inserted (plug-and-play) between your new Alpine headunit and the required interface harness, as I mentioned in my previous post (see diagram above).
You don't have to do/change anything. It will provide upgraded power only to your JL Audio c2 350x & 525x speakers.
Single din in c5 z
