Sorry about the lack of images previously, anyway I have a diagram of how I am going to lay the wiring for my 380 fit out.

please see the attached image for the diagram. This is a good clean upgrade and save the custom mount can be fitted in under an hour.

The other option is of course to rewire the whole engine bay, expensive and over the top. I would recommend only upgrading the factory engine and battery grounds to the same gauge as your amplifier wiring.

Note: for those that have grounding issues in the 380 add a second battery ground on one of the suspension hats/swaybar, this should help.

Thanks guys will post again soon when I am fitting my amp (mount is still undecided).

ill be watching this with great interest......i have to do the same shortly and am a little stumped atm as to how i will plan it all out.....

make sure you inform us how you go routing your cabling, i see that the 380 has a very well moulded floor carpet, my aim will be to route the cabling so as not to make the carpet want to lift....

touching on your other thread, you say you have lost no functionality with your h/u install, were you able to retain the audio display in the LCD screen?

i am unsure yet as to whether i will upgrade the factory h/u or just go with a rockford fosgate 360.1........the latter option will probably be cheaper, dunno yet..

Sorry I should clarify I have lost the audio display on the lcd, I wasn't aware their was a rockford option for the 380. I will deff try my best to provide detail on my routing for you.
