Hello.
I'm at the end of a project installing an amplifier into my rear tailgate door card to power 'a few' speakers bolted onto the door card in a custom rack I designed.
The task is nearly complete, but I just remembered as I was going to buy an 'amp wiring kit' that the distance from the amp (outside the car) to the chassis of the vehicle (inside) is over the recommend spec of 18 inches (1.5ft).
It seems I'll now have to ground the amp into the metal frame of the tailgate door, not the chassis in the car, as the swing out Freelander door, isn't the chassis as its connected by two door hinges.
The only compromise I can think of, is to run thicker 4AWG cables instead of 8AWG from the amp to a distribution block (in the boot), then 0 AWG to the battery, as I believe the thicker the gauge cable, the less it matters if the ground cable isn't a short run to the amp, and this should overcome the problem of resistance of a long ground cable.
Could someone kindly tell me if this is correct I have two options?
1) Ground the amp in a short run into the metal frame of the Freelander tailgate door
or
2) Use 4AWG long run into the boot, then upgrade to 0AWG to the battery.
Thanks for any input.
