Slightly, just because you'll need a power and ground. But its just 18 gauge wire, so you can basically tap into any power in the vehicle. Not bad at all. See the problem is, doing it the way you want it'll sound decent at low volume, but factory stereos as you turn the volume up the bass cuts out to preserve your factory speakers. The LC2i pro gives you back full bass at higher volumes.Would that be more difficult to install?
