Pair KICKER 46CSC464 4x6" 300 Watt 4-Ohm 2-Way Car Audio Coaxial Speakers CSC464

The 46CSC464 is a pair of CS-Series 4x6-inch two-way coaxial speakers built to drop straight into factory 4x6 openings in dashes and rear decks. The oval format is common in older domestic cars and trucks, and the replacement options that actually fit are limited, so build quality matters more than usual here.

These use a heavy-duty motor and magnet structure with EVC Extended Voice Coil technology, giving longer, more linear cone travel than the stock driver they replace. The cone is rigid polypropylene on a stamped-steel frame, wrapped in a ribbed, UV-treated poly-foam surround that handles years of dash-top sun without breaking down.

Near-zero tweeter protrusion is the detail that makes the install painless. The 1/2-inch PEI dome tweeter with a neodymium magnet sits flat against the cone plane, so factory grilles reseat without contact. Top mount depth is 5/16 inch and bottom mount depth is 1-11/16 inch, which clears most shallow dash cavities.

Each speaker takes 50 W RMS and 150 W peak, with 88 dB sensitivity and response down to 50 Hz. That low-end reach is unusual for a 4x6 and comes from the large magnet and controlled excursion. Run them from a head unit for a clear improvement, or from a small four-channel amplifier for real volume in a factory-shaped hole.
