Hoping someone can help me out with this. First time I've owned an Acura and trying to figure out what I did wrong here. This is an MDX base package.

My front speakers quit working. Both of them, so I figure this is likely either the factory amp or the head unit. So I just decided to install an amp and sub along with an AudioControl DM-810. (note - I already had these items, so that's what I used) I also installed Morel components in the front about 6 months ago and they have been working fine until about a week ago. Note I'm using the Morel's crossovers and only have the door speakers powered.

The AudioControl DSP allows me to bridge any input to any output, so my goal is to simply rout the signal from the back speakers to the front speaker as well as the sub. So, essentially my amp will only be powering the front speakers and the sub, so I need to keep the rear speakers wired from the factory amp, while tapping into them. Hope all that makes sense. Here's what I did:

I spliced into the 4 wires from the factory amp to the rear speakers and sent those to my DM-810 (keep in mind, they are also still going to the rear speakers). At first I simply cut the 4 wires that go to the front door speakers. I connected the speaker outputs from my amp to those 4 speakers wires (so the original 4 from the factory amp are disconnected). Of course I ran power, grounds and remote. Sound all works great now, but I have multiple lights triggered (tire pressure, transmission, engine-something-or-other, etc). I re-checked all my connections, made sure ground was good, disconnected battery for a bit, drove it a few miles - nothing has changed. So - at that point - I disconnected the output wires from my amp and re-connected the 4 front speaker wires to the factory amp. And alerts are still there. Now I don't know what to do. Do I break something? The only thing currently different than before is I still have the 4 back speaker wires spliced into - but they aren't going anywhere - I disconnected them from my DM-810. It was a PITA to splice into those - and I'll undo it if I have to but can't see that being the issue if they are open on the other end. I've installed car audio gear my whole life and have not seen this before.

Help?

 

Weak battery, while still able to start the vehicle, can trigger multiple warning for various systems.
At this point testing the battery (load testing, cranking power, battery capacity etc.) would be my first step.
Replacing the battery solved similar issues (warning lights for various systems) for many owners of MDX.

 

Thank you - I'll test it and see. I'd hate to have to buy a new one, but at the same time I'd be relieved if that's all it is.
