SO I just swapped the stock battery for an xs power d6500 and afterwards my headunit (DNX890HD w/ maestro) is almost completely unresponsive. A few days ago the subs just quit working also. I've checked all wires and fuses and no damage. Not sure what's going on but I'm about ready to take this slow *** kenwood out and go with something else. If anyone has some ideas to troubleshoot I'd appreciate it.

I would try a different battery (not sure why that would effect your stero). It's the cheapest and earliest way to check if it was the battery. Try interstate battery's. I've never had problems with them.

Different battery!? It's brand new and probably one of the most powerful ones you can fit in stock location....it's not the battery trust me.

then why are you tying the install of your new battery to your head unit not working...

Hell I don't know I'm just sayin it worked fine before...maybe something shorted out, that's why I'm askin cause I don't know what the hell it could be.

check the fuse would be the first step.

Have you tried lifting the battery terminals again for 10 minutes or so to give the head unit a chance to fully shut down and reboot with the new battery? If you've already done that then check all your fuses again. If they're all okay then I would start by checking the constant and accessory voltage inputs on the head unit and the voltage supply to your amp.

Unresponsive meaning it powers up or no? Since the problem appeared when you changed the battery the first step in troubleshooting would be to reverse that change. Did the subs quit working before, after, or at the time of your battery swap? Maybe something happened either to the Kenwood or maestro while you were swapping the battery out

the HU may also have a fuse in the back. check that one also.

Ok I took it to my audio guy and we messed with everything. It turns out all of this was due to 1 dang setting on the deck itself. I guess when I reset the deck it was only sending the Bluetooth signal to the front stage. I feel like a retard but there are so many menus on this thing I can't remember where everything is. As far as it being "unresponsive" yesterday, I haven't the slightest idea why it was acting like that but it's all good now.
