4x6" Dash Speaker Replacement Kit For 1984-1991 Cadillac Seville

A pair of Kicker 43DSC4604 4x6 two-way coaxial speakers and a matching METRA 72-4500 harness turn this into a direct dash speaker replacement for the 1984 to 1991 Cadillac Seville, with the harness plugging into the factory connector so there's no cutting or splicing involved. Each speaker is rated for 120W peak (30W RMS) power on a 4 to 30W RMS recommended range, which covers a factory radio or a modest aftermarket deck comfortably. The polypropylene midwoofer and acoustic-foam surround add control to the low end that a decades-old factory speaker has long since lost, and the zero-protrusion polyethylene-naphthalate dome tweeter keeps the highs clear without sitting proud of the dash grille. Frequency response spans 50 to 20,000 Hz with an 88dB sensitivity rating, and the 4 ohm impedance lines up with the Seville's factory wiring. Because the METRA harness ships as a pair, both dash locations get the same clean, connector-to-connector install. This kit is sized and wired for the Seville's dash opening specifically, not a universal-fit speaker.
