Noisy because of old window seals so I bought a rear channel amp. Itâs a Harman Kardon CA-212. Straight forward, I thought, but I am getting no sound from the rear speakers. Itâs my first amp install, so I am not sure everything is correct. Can I get some help with the trouble, please?
Front L/R speakers still work right and are wired per schematic.
I disconnected the greens and purples from the HU that were attached to the rear speakers and attached them to the AMP- NO CONNECTION TO HU DIRECT FROM REAR SPEAKERS.
Front amp light comes on. Multimeter shows 12.6 at the remote lug on back of amp.
+B lug on back of AMP gets full 12v directly to battery (5amp fuse good).
Amp ground at chassis grounding bar â" will verify solid connection.
RCA Line connectors verified to HU REAR L/R jacks.
HU wires not used: steering remote/mute/ant control/Green L/R and Purple L/R.
All HU functions otherwise intact. I have selected 6x9 rear speakers, and ALL speakers in the AUDIO SETUP of the HU.
What am I missing?
