Looking into earth and power for the amp.
I changed the orientation of the amp so the power and speaker connectors were facing the trunk. I did this to take advantage of the factory amp bracket mounting stud. It’s basically the same as what BMW uses for the earth Combes earthing points around the vehicle. Uses an 10mm bolt so it’s 6mm in diameter. I checked it with a multimeter and it’s 0 ohms to ground so absolutely fine as a earth point.
Mobridge uses 6awg /16mm2 cable leads so just got a 16mm2 with 6mm hole lug.
Also ran a 4 awg cable through the back of the trunk pannel as mentioned in an earlier post. Used a curtain wire to pull the cable through. It’s from my last audio build so it’s wrapped in a plastic protection sheath. Also lined the entry and exit holes with Tesa tape. Note.
The short run distance is fine for 6awg to the battery. However. 4awg will have a slightly lower voltage drop.
I’ll leave as is for a few days and see if it causes any rattles. If it does rattle I’ll change the cable route to back of trunk under the trunk floor past the fuse box.
