Hi I was hoping to get some advice on a suitable ground point for an amp please? I was thinking under the rear seat but a bit unsure as the hybrid battery is located there, any advice would be much appreciated. Thanks
Hybrid battery doesn't change much... you can still use just about any bolt head or exposed tab you want. Just take note of what is actually part of the floor and what is part of the battery case or cover panel and pick something that doesn't need to be removed for other service.
The wiring diagram has a section showing where all the existing ground points in the car are. There are a lot, so probably one is near where you would want. If I remember right, the factory ground points are secured with thread-rolling screws, as opposed to the thread-cutting screws used elsewhere for mechanical attachments, so there should be a conductivity advantage at the intended ground points. (Not to mention that you also end up with harness grounds in parallel with your connection to the body.) -Chap
