Hand-Drawn Radio to PAC Adapter & Amp Wiring Question Sketch - 2008 Jeep Wrangler

This is not a printed factory wiring diagram; it is a rough hand-drawn sketch (apparently made in a paint program) illustrating a question about a car audio installation. The sketch shows three labeled boxes: RADIO, PAC (a line-output converter / interface module), and AMP. A wire runs from the RADIO to a small unlabeled connector marked 'to speakers,' which connects onward to the PAC box. Several parallel lines (a multi-wire bundle) loop from the PAC down toward the AMP box, with a hand-drawn arrow pointing back toward that bundle annotated 'not here right?'. Across the bottom the uploader has written the central question: 'Where does output go?'. The drawing appears to be a forum-style query asking where the output of a PAC adapter should be connected relative to the radio's speaker wiring and an aftermarket amplifier. The document contains no part numbers, wire colors, fuse data, pinouts, years, makes, or models, so it cannot confirm or contradict its attribution to a 2008 Jeep Wrangler. It is useful only as a discussion aid, not as an authoritative wiring reference.
