Hi, this is my first post in the forum, and it may be naive. I have a pair of car speakers that I got free in a deal but don't need them for my car. Here are the details from its manual - Model - Dual XP65i 6.5" 2-way speakers Peak Power Handling - 120 Watts IPP Recommended Power Range - 2-50 Watts RMS Frequency Response - 75-20K (Hz I suppose) Sensitivity - 87dB Can I connect them to the sound card in my computer? Is it compatible? What is IPP and RMS watts?
