Even the most basic car audio system involves multiple speakers peppered across the length and breadth of the vehicle’s interior. The painstaking process of routing wires through roof liners, panels, and conduits will be time-consuming. A wire puller makes this task a lot quicker and frustration-free.
Also known as a wireworm, this tool is typically a flat length of plastic with hooks or eyelets at both ends. Snaking it through tight spaces is easy thanks to its inherent rigidity and slipperiness, which allows it to pull wires through conduits that are otherwise too tight and long to feed cables across the usual way.
It is tempting to save money on a wire puller by disassembling the interior panels and liners instead, but even that might not help in some cases. Most notably, routing wires through tightly packed conduits such as the one found on the tailgate is a nightmare without one. The tool also pays for itself if you must tackle challenging cable runs, such as the one for trunk-mounted subwoofers.
If you’re on a tight budget, a reasonably thick solid-core copper wire will also work in a pinch. A suitably thick (approximately 6 AWG) length of bare copper wire is rigid and slick enough to be pushed through tight spaces. The lack of insulation also prevents it from snagging against the plastics, carpeting, and rubber conduits.
