Excuse me if I sound like a novice but I've never experienced with audio before. I recently purchased a set of Skytec SL6s 150w loudspeakers, however when I connected them using a 3.5m to 6.5m audio cable to my laptop or iPhone the audio is very quiet which leads me to believe they require more power. If I were to connect them to a home stereo would they deliver louder audio? Any advice is greatly appreciated.

Is plugging both speakers directly into the home stereo safe? I am using standard 3.5m audio cables. When tested it delivers loud and clear audio.
