2 door. I ran the wiring on the inside. Power on the left, audio on the right. This reduces the risk of interference ( which your amp will amp)
There's a rubber grommet on the left side of the car just above the passenger footwell ( also the batt is on the left ). I stretched a hole in this carefully with a screwdriver & followed it with a file. My mate watched the engine bay side in case I was going to kill a wire.
The covers by the doors clip off upwards. There's just enough space for 0AWG Wiring. I poked the wires behind the rear panels & out under the seats. Then under the backrests to the boot.
If you've got a single din head unit, allow time to keep pulling it in and out until the wires get out the way & it slides in freely. ( it's a bit tight behind the CD player )
