16journey Posted January 20, 2017 Report Share Posted January 20, 2017 I have a 2016 journey with the 4.3" radio screen. I decided to upgrade the speakers by cutting the speaker wires behind the radio and useing a lc7i processor to feed my amps. The radio powers up and seems to work fine however does not send audio signal. My wiring was fine and checked by a store. There is no factory amp and according to the dealership the car is showing "open speaker circuit". Any ideas what's going on and what the fix could be?

bramfrank Posted January 20, 2017 Report Share Posted January 20, 2017 (edited) The fix is simple enough; wire 5 watt 8 ohm resistors across the speaker lines (which is a common value though I believe the factory speakers may be even lower impedance) and the radio will think it has speakers connected.

16journey Posted January 21, 2017 Author Report Share Posted January 21, 2017 I knew it was going to be something stupid lol. Is this only across the positive side or do I need to do both positive and negative? Quote Link to comment Share on other sites More sharing options...
yyz Posted January 21, 2017 Report Share Posted January 21, 2017 (edited) You would need to wire the resistors across the positive and negative leads to simulate a speaker load.Not sure how warm they might get though if the volume was up loud I took a quick look at a lc7i processor if it accepts speaker line level inputs you would think it should simulate a load to the factory system but the specs I saw said input imedance was 20k ohms Edited January 21, 2017 by yyz Quote Link to comment Share on other sites More sharing options...
