I have a friend that gave me a set of speakers for my home sterio. I found out after I had been using them for awhile, that the subwoofers were 4 Ohm Car Audio speakers and not for the home sterio. I have a Kenwood full stack (tuner, cd, pre-amp, amp, digital eq) with Dolby Pro Logic.
My question is, will thoes speakers do any harm to my sterio? If so, what?
