About the Kicker 49ST3TW
From our tech experts at CEN
The Kicker 49ST3TW is a single 1-inch (25mm) Street Series bullet tweeter rated at 50W RMS, with a horn-loaded aluminium diaphragm and 106 dB sensitivity. It covers 3.5kHz–20kHz and is built for competition-level SPL car audio systems. An in-line 6dB high-pass crossover and mounting hardware are included.
Who it suits
This is a specialist tweeter for high-output SPL builds where clear vocals need to cut through heavy bass. It suits experienced builders pairing it with a powerful amplifier. For a simpler door speaker upgrade, a 2-way coaxial from the Kicker DS Series may be more practical.
Our tech experts advise
The 49ST3TW is sold singly — buy two for a stereo pair. Mounting diameter is 58mm with a 30mm depth, so measure your chosen location before fitting. Keep amplifier power between 15W and 50W RMS at 4 ohms; the included crossover handles high-pass filtering. Car audio installation is priced per vehicle — contact us to discuss fitting.
