Stereo help

[gus 08 mobius lsv]

I have no power to head unit or amps...my first thought would be fuse. I have power to everything else as far as I know.I've had very little free time. Any idea to location or places to check or any other ideas ? I have someone scheduled to look into this issue tomorrow. Any help would be great.

When you say no power, do you mean that the head-unit will not come on or you have taken a volt meter to the head-unit and amps there is no battery B+? From the factory, the amp(s) and head-unit would each have their own circuit protection, whether its a fuse or breaker. Also, the head-unit needs a switched turn-on 12V trigger on the red lead. Amps will not wake up until the head-unit turns on.

Is the system was installed aftermarket, things could be different. Have you checked the battery levels with a meter?

I've pieced my system together over my first few years and was installed professionally. I have an on bank charger I keep on the batteries but haven't put a tester on them. No power at all at headunit. Dual battery system as well

Headunit won't power on at all

Theres 3 circuits at the back of the head-unit that would prevent it from turning on. Amps wont wake up until head-unit does.
