ALPHASONIK NS46 4x6" 2-Way Car Speaker Pair 120W 40W RMS 3 Ohm

Pair of 4x6" 2-way car speakers

The Alphasonik NS46 Neuron Series supplies a pair of 4x6" full-range speakers rated at 40 watts RMS and 120 watts peak power. They present a 3 ohm impedance and a sensitivity of 80dB with a frequency response from 70 Hz to 20kHz. A polypropylene cone and PEI tweeter combine with an integrated crossover for consistent playback. The heavy-gauged stamped steel basket reduces vibration and distortion.

Upgrade from factory single-cone units

These speakers replace basic OEM drivers that lack a dedicated tweeter and crossover network. The jump is worth it when you want clearer highs and better midrange definition without adding external components. The 3 ohm impedance can draw more power from many factory head units than standard 4 ohm replacements. Buyers who need deeper bass below 70 Hz or higher output for competition use will need larger drivers or a subwoofer.

Check mounting space and wiring

Verify the mounting diameter of 5 3/4" and depth of 1-3/4" fit your vehicle's door or dash openings. Confirm the overall diameter of 6" clears any interior trim or window mechanisms. Ensure your head unit or amplifier is stable driving a 3 ohm load per channel. The pair connects with standard speaker wire; no proprietary connectors are required.
