Box Guidelines

Jensen recommends that you have your subwoofers professionally installed. If choosing to do your own installation, please note the following:

Make sure all moving parts and factory electrical wires are cleared.

Leave slack in the wire to prevent pulling or stretching.

Tie down wires to prevent them from getting caught or shorted.

Do not mount subwoofers where they might be subjected to moisture.

Correct subwoofer polarity must be used. The polarity positive side is marked by a (+) sign or red dot. Subwoofers out-of-phase will have little bass output.

Speaker frames will be twisted by installation on uneven surfaces. This occurs when the surface is carpeted/padded and screws are over-tightened.

If using more than one subwoofers, be sure that the combined impedance values cannot damage the amplifier.

Speaker wire should be isolated from the vehicleís electrical system to avoid noise being picked up by the amplifiers.

Speaker wire should be large enough to carry the full power of the amplifier. 14 gauge or larger sizes are adequate.

Be sure to give your ears a break if you listen loud. Listening loud for extended periods can damage your hearing!

JPW410, JPW412 specifications

The Jensen JPW410 and JPW412 are innovative two-way speaker systems that have garnered attention in the audio community for their impressive performance and user-friendly design. Both models embody Jensen's commitment to quality sound reproduction and aesthetic appeal, making them suitable for both home and professional environments.

One of the main features of the JPW410 is its robust 10-inch woofer, which delivers powerful low-frequency response. This component allows the speaker to produce deep, rich bass tones, ensuring that every note is felt as much as it is heard.

Both models employ a high-quality tweeter that complements the woofer for a complete sound experience. This combination ensures that users enjoy a wide dynamic range, with crisp highs and well-defined mids, making them ideal for various music genres. Whether it’s rock, classical, or jazz, listeners can appreciate the detailed soundstage that these speakers provide.

In terms of technology, Jensen incorporates advanced magnet structures within both models. This innovation not only improves the efficiency of the drivers but also minimizes distortion, making for a cleaner sound profile. The speakers’ designs also feature durable cabinets built to reduce resonance, ensuring that sound purity is preserved while also providing an appealing look that can fit in with any decor.

Jensen has also integrated modern connectivity options that allow for seamless integration with various audio systems. With capabilities for connecting to both wired and wireless setups, users have the flexibility to enjoy their favorite music without hassle. Additionally, thoughtful engineering includes built-in protection circuits that safeguard the speakers against overload, ensuring longevity and consistent performance.

The JPW410 and JPW412 stand out not only for their sound quality but also for their sleek design.
