Installed this in my 2016.5 Mazda CX-5 without Bose last week, to add an accessory amp (Sony XM-S400D). No subwoofer. Got everything hooked up after @theblooms showed me where to splice in for speakers.
Everything works, but there's a loud "PAP!" every few seconds from the speakers. I checked the connections I made, and there are no opens or shorts. Running clean 12V from the battery terminal with 12 AWG wire, and have solid ground. Using the remote turn-on from the amp, not the interface, and it's wired to an unused location on the interior fuse panel.
Also, did a bench test on the amp, and it's working properly. Is the interface unit defective?
