It's still a "how-to properly install" question. When mounting amps/lights, do you first mount the light/amp, and then run the wiring? Or do you run the wires, and then mount the light/amp?
I have a loose "routine" for doing installation work:
1. "Lay out" the vehicle; get an idea of where everything is going to be mounted to help with logistics;
2. Get all the wiring/supplies you'll need. It's easier to run one long piece of wire than to splice it six times and add resistance across the board;
3. Mount all your equipment, lights, boxes, speakers, trunk trays, consoles, etc: this
does not include things like partitions or transport seats that could make it more difficult to run wiring or mount other equipment;
4. Run all your wiring, cables, harnesses, and whatnot to the equipment requiring it, and make your connections at the load/receiving end (i.e. hook lights up to wires at the light-side of the circuit);
5. Mount partitions, transport seats, gun racks, and anything else left over;
6. Finish making connections and complete the wiring.
Some people run the wiring first, and mount second, but I have always found it infinitely easier to mount first, and deal with wiring second, as running wiring first may end up limiting how (or where) you mount your equipment.
