I’ve seen a few folks lean toward a hardwired setup since it tends to give more consistent power and avoids the battery drain headaches that can come with some plug-and-play models. With a hardwired install, if you’re comfortable with ripping into your vehicle’s wiring, it’s doable DIY, but having a pro take a look can help avoid any unforeseen issues with your car’s electrical system. I’ve had a friend use a well-reviewed model that integrates seamlessly with their car’s fuse box, and it seems like a solid balance of reliability and safety.
