I know the profile says Regal Limited but I also have a 93 Volvo 940. I was wondering if someone knows what would be the best way to run the power wires.
Find a hole in the firewall in the engine compartment for starts or if there isn't one you may have to drill one then when you come into the car pop off the door sill panels and run wire under there right to trunk. Be sure not to pinch wire and always run your rca's on the oppisite side off car. Also I usually run the ground to a seat belt bolt. Make sure you sand to metal where your putting your ground.
