Did you do the installation wiring yourself? Is the lower RPM, rough idle, etc. only when the sound system is playing or all the time since the install?
I would check your alt, check your battery.
As was previously stated 120w is nothing, and should not effect your electrical in the least. Even if your Honda has that fuel saver feature...this is 120w we are talking about...unless your alt isn’t running for an hour or two, it should make no difference.
The only thing I can think of, is either a bad battery, or an alt, that isn’t doing its job. But most likely a bad battery. Is your battery the original?
Nop. I had a shop do it for me. When idling its fine, say my car is in neutral. It idles at around 600. When I move it Drive the rpm meter shifts down a little and thats where the car gets shaky/ Vibrates. The battery is original but I can say its old. Maybe that is causing the issue. Can't say for sure.
