Car speaker JBL Marine 6 — 180 W peak, 4 Ω impedance, 90 dB sensitivity, weather-resistant

The JBL Marine 6 is a 6.5" (16.5 cm) car/marine speaker designed to provide clear audio with robust power handling. With a rated speaker output power of 60 W and peak power up to 180 W, the speaker offers a wide frequency response from 60 Hz to 20 kHz and a sensitivity of 90 dB. Built for marine use, the enclosure and components resist moisture and environmental exposure, making the speaker suitable for outdoor and onboard installations. The unit is finished in white to blend with marine and vehicle interiors.

Advantages

The speaker combines durable, weather-resistant construction with JBL audio engineering to deliver consistent sound in damp or variable conditions. Its 4 ohm impedance and 90 dB sensitivity allow efficient power use from common car and marine amplifiers. The 6.5" driver provides balanced midrange and treble reproduction across a wide frequency range, while the white finish offers a neutral aesthetic for installation on boats or vehicles.
