Dual Speaker to Amp Wiring Diagram - Series vs Parallel Subwoofer Hookup

This document is a hand-drawn (computer-drafted) car audio speaker wiring diagram, exported with an 'Unregistered Preview Conversion' watermark. It shows two side-by-side wiring arrangements, each depicting a pair of round speakers (drawn as circles) connected to an amplifier, represented as a rectangle labeled 'AMP' with '+' and '−' output terminals. In each layout, red lines indicate positive-side wiring and black lines indicate negative/return wiring between the speakers and the amp terminals. The left diagram appears to show one wiring configuration (likely a series-style hookup based on the single wire path linking the speakers), while the right diagram shows an alternative configuration with separate wire runs from each speaker to the amplifier terminals (a parallel-style hookup). The diagram contains no fuse ratings, wire gauge specifications, part numbers, model years, or vehicle-specific information; it is a generic aftermarket audio reference. The companion file in the album (2_4ohmSVC_2ohm.gif) suggests the diagrams relate to wiring dual 4-ohm single-voice-coil subwoofers to achieve a 2-ohm load, though that is not stated on this image. A reader can learn the basic polarity and terminal connections for hooking two speakers to a single amplifier channel in two different ways.
