1. Read these instructions.2. Keep these instructions.3. Heed all warnings.4. Follow all the instructions.5. Do not use this device near water.6. After removing the product from its packaging, keep the packaging out of the reach of children. It poses a suffocation risk.7. Never use chemical products or abrasive detergents to clean the device. Clean with a dry cloth only.8. Do not obstruct ventilation openings, as this may alter the sound quality of the device.9. During storage, the device should not be exposed to temperatures below 20°C or above 80°C. The operating temperature range for the device is between -10°C and 50°C.10. If the product emits smoke or an unusual smell, immediately turn off the power supply (turn off the ignition and remove the key) and stop using it. Contact your retailer as soon as possible.11. Do not turn on any function likely to distract you when driving. Functions or settings that require prolonged attention should only be used when the vehicle is at a complete stop. There is a risk of accident.12. Do not listen to the loudspeakers at a high volume, so that you can hear external noise when driving.13. If cords or connectors are supplied, use them properly as described in the user manual without replacing them or modifying them.14. If the kit or connector includes a fuse, it must only be replaced by a fuse of the same rating.	15. Do not attempt to repair this device yourself. Opening the device may expose you to dangerous voltages or other risks.16. All maintenance tasks should be performed by a qualified professional. Maintenance is required in case of any kind of damage to the device (spillages or objects inserted into the device, exposure to rain, if the device malfunctions or is dropped, etc.).17. When replacement components are needed, make sure that the maintenance technician uses the components recommended by the manufacturer or components with exactly the same technical features as the original product. Using non-compliant components could cause fires, electric shocks or other risks.18. After any maintenance or repair work on the device, ask the maintenance technician to test it to check that it is working safely.19. If a subwoofer is installed in the vehicle, it is essential to secure it by attaching it solidly. We recommend attaching the subwoofer to the floor or chassis of the vehicle for safety. If it is not properly secured, it could become a projectile in the event of an accident. This is even more important if the subwoofer is installed in a hatchback, a station wagon, a utility vehicle or a van.	20. Some users who are not self-sufficient enough to use the product on their own without danger. In particular, children under 14 or people with some types of disabilities must be supervised and/or accompanied when using the device.21. To avoid damaging your hearing, do not listen to loudspeakers at high volumes for long periods of time.Listening to loudspeakers at high volumes can cause damage to the user's ears and may lead to hearing problems (temporary or permanent deafness, buzzing in the ears, tinnitus, hyperacusis). Exposure to excessive volumes (over 85dB) for more than one hour can cause irreparable damage to your hearing.

The methods of installing and mounting loudspeakers to any surface (bracket, ground anchoring, etc.) depend on the conditions and standards of installation, refurbishment, safety and cabling in force and applicable to the surfaces and/or brackets involved. In addition, the products may vibrate and damage the brackets onto which they are mounted. For this reason, the installation operations must be performed by a qualified professional who is familiar with installation and safety standards. Focal does not provide any end-of-use warranty for a given bracket or installation, as installing the loudspeakers is the customer's sole

responsibility. Focal is therefore not liable in any capacity whatsoever in the event of incident, accident and/or any other result or damage of any kind related to the installation of loudspeakers.

Thank you for purchasing a Focal product. Welcome to our High-Fidelity world. Our values are innovation, tradition, excellence and pleasure; our one and only aim is to bring you a sound that is rich, pure and true. To get the most out of your product, we recommend that you read the instructions in this booklet, then store it in a safe place to refer to in the future if needed.

Important recommendations

First of all, check the space available for fitting the speaker drivers (refer to the plans on the packaging) then proceed with the cutting required. If mounted in the factory location, check that there is sufficient space between the speaker driver and the protective grille.

• Keep the speaker drivers clear of any metal shavings and dust particles during the cutting process.
• Clean thoroughly before fitting the speaker drivers.
• Ensure that there are no objects positioned across the grille, as this could damage the speaker drivers.

Choosing an amplifier

It is not an excess of amplifier power that can damage your loudspeaker and drivers, but rather a lack of power. It is recommended to use an amplifier that delivers 20% more power than the system's total power to avoid a surge or damage to the products. Your dealer will be able to guide you, depending on your tastes and budget.

Ensure that you follow the recommendations for your amplifier in order to correctly connect each product from the K2 Power line.

Pre-installation wiring

You will only be able to begin fitting your products once you have connected them using the terminal block on the speaker drivers (fig. 1, 2). We recommend using a cable with a marker to ensure the polarity of the speaker drivers is respected (+/-).

Bi-amplification cabling

In a bi-amplified 2-way kit (4-channel amplifier), make sure you follow (fig. 3, 4). In a bi-amplified 3-way kit (4-channel amplifier), make sure you follow (fig. 5, 6, 7).

Installation

Please use suitable screws to avoid damaging your sub, your vehicle trim or any of its other components (fig. 8).

Loudspeaker positioning

The loudspeakers in the range have been designed to deliver the most faithful sound reproduction for any style of music. Nonetheless, a few simple rules should be followed to optimise their performance and to guarantee good tonal balance and a realistic sound image.

SUB 25 KXS / SUB 25 KXE / SUB 30 KXE

It is essential that the subwoofer is contained within an enclosure of suitable dimensions, to create an appropriate internal volume that will maximise the performance of the selected speaker driver (fig. 18). Please use suitable screws to avoid damaging your sub, the floor of your vehicle or any of its other components (fig. 20). Connect your subwoofer to the amplifier using the terminal block located on the side of the speaker driver (fig. 20). Ensure that the subwoofer is pointing towards an open space in order to achieve the best performance.

SPECIAL PRECAUTIONS

Maintenance

To look after the K2 Power speaker drivers, simply dust using a dry cloth. If the grille is marked, we recommend that you use just a damp cloth. Never use solvents, detergents, alcohol or corrosive products, scrapers or scouring utensils to clean the surface of the speaker drivers.

Running-in period

The speaker drivers used are complex mechanical components that require a running-in period to operate at their best. This running-in period varies depending on the conditions in question and may take several weeks. To reduce this time, we recommend operating your speaker drivers for about 20 hours at a moderate volume. Once the speaker drivers' characteristics have fully stabilised, you will be able to enjoy the performance of your K2 Power products to the full.

Warranty terms and conditions

All Focal loudspeakers are covered by guarantee drawn up by the official Focal distributor in your country. Your distributor can provide all details concerning the conditions of guarantee. Guarantee cover extends at least to that granted by the legal guarantee in force in the country where the original purchase invoice was issued.
