JVC CW-DRA8 Pre-loaded subwoofer 150 W

The JVC CW-DRA8 is a pre-loaded subwoofer designed for in-vehicle audio systems. It provides a rated RMS power of 150 W and peak power up to 250 W, reproducing low frequencies in the 35–150 Hz range. With compact dimensions of 350 mm (width) × 240 mm (depth) × 75 mm (height) the unit is suitable for tight installation spaces while delivering reinforced bass for car audio setups.

Advantages

The pre-loaded design simplifies installation because the subwoofer comes mounted in an enclosure. The 150 W RMS power ensures consistent low-frequency output while the 250 W peak rating handles brief dynamic peaks. Frequency response from 35 to 150 Hz focuses the output on deep bass reproduction. Integrated remote control allows adjustment of volume, cutoff frequency and phase without accessing the subwoofer directly.

Suitable for

• Car audio systems needing enhanced low-frequency performance
• Installations with limited space where a compact subwoofer is required
• Users who want external control of volume, frequency (crossover) and phase via a remote

How to use

Mount the pre-loaded subwoofer in a suitable location in the vehicle where the enclosure can be secured and wiring can be routed to the head unit or external amplifier. Connect the power, ground and remote turn-on leads according to the vehicle wiring and the user manual. Use the supplied remote control to set the subwoofer volume, adjust the crossover frequency within the 35–150 Hz range, and correct phase to match the rest of the system for coherent bass response.

Recommendations

For best results, set the crossover frequency to blend with your main speakers (typically near 80–120 Hz depending on speaker capability), keep gain at a level that avoids distortion, and verify phase alignment by listening to bass response at moderate volume before finalizing installation.
