SU2 install, lost front speakers

Post by JonathanR » Tue Jul 03, 2018 10:14 am

Hello,

Last night I installed the SU2 (v1.4)+ Maestro RR + Kenwood DMX77042s. The car has the 7" Starlink system with NO Harmon Kardon, so no amp. All is working great except that I lost audio on the front dash tweeters and door card speakers. I tried swapping front/rear speaker wires, audio still only came out in the rear. This eliminates the Kenwood as a cause I swapped out the old stereo (stock) and it still didn't work, this means it's not the SU2/Meastro. I also tried bypassing the harness altogether and going direct from Kenwood harness to the pins in the 10-pin harness, also did not work.

I know this isn't idatalink/maestro problem, but I'm wondering if anyone has any ideas as to what I screwed up? Maybe I shorted something somewhere during the install? Is there a ground point anyone knows of that I may have disturbed? Any ways to trouble shoot?

My next step is to pull out the front 4 (2 in door + 2 in dash) speakers and check their resistance, but it seems odd that all 4 could fail. Can one failing cause all 4 to go haywire?

My last resort is to try and run new wires directly from the stereo to speakers.

thanks!

The starlink unit needs to be put back in. The front channels run through it.
