Little bit of misinformation there. ARPA of America owns both Zapco and ARC Audio. Robert Zeff is the main engineer for both companies and has been for years. Zapco was, and still is among the best of the best when it comes to car audio amplifiers. Their DC Reference series is a feature packed amp whose performance is very very good.
As for the OP's question regarding I-Force components. They are my go to line for bang-for-the-buck type installs. They sound very good. They (Zapco I-Force Speakers..as well as their higher end lines of speakers) are manufactured by ESB in Italy.
