Puzzled ! How do I wire these Kenwood w112S? I looked in the manual & they show series & parallel why can I just put each + to + & - to-, when you wire series or parallel you only end up with a left & right not 2 lefts & 2 rights. Please answer! Need help trying to install system for my niece FYI they are wiring to a ATA 2600.2 amp has 2 left & 2 right posts for speaker hook up.
