SAFETY PRECAUTIONS

• Prolonged exposure to sound pressure levels above 100 dB can lead to hearing loss. Use common sense and practice safe sound. Be aware that prolonged exposure to high sound pressure level can damage your hearing. Safety while driving is first and foremost. The manufacturer is not responsible for hearing loss, bodily injury or property damage caused by misuse of this product.
• Safe Limits of Operation
  Damage to speakers can happen when a car amplifier, regardless of its rated power, is developed to play at higher listening levels than it can produce at low distortion levels. This in most cases is beyond the “noon or 1 o’clock” position on the volume control. Work at this level can cause very high levels of audible distortion originating in the amplifier, which can add a harsh, distorting sound to your listening music tracks. Versus to popular belief, a speaker is highly likely to be damaged by trying to get too much volume from a low-powered amplifier or receiver than from a high-powered one.

Proceed with the installation only if you are qualified installer, otherwise contact a professional installation center.
Always wear safety goggles when using tools.

Before proceeding with the installation, turn off the car radio and other electronic devices.

• Disconnect the negative(-) terminal from the car battery before starting installation.
• Store the speakers in their packaging until you have started installing them, and always place the speaker with the cone up.
• Never use excessive force when installing speakers.
• Determine the location of the fuel line, brake pipe, oil line, and vehicle electrical wiring before proceeding with installation.
• Check that the installation site has sufficient air circulation on both sides of the speakers before drilling holes.
• Check that nothing obstructs movement of the cone, otherwise the cone will be damaged.
• Use a utility knife to cut off excessive carpet near the hole where the speaker will be installed before you start drilling. It is very difficult to achieve high-quality isolation if the carpet (fabric) and a gasket are between the speaker and the acoustic enclosure.
• Use an insulating sleeve for the speaker cables when pulling through thin metal sheet, otherwise the cable may be damaged by the metal edges of the hole.

EXAMPLES OF CONNECTION AT 4 OHM

• Your midrange speaker has a single voice coil and is rated for 4 ohms .
  You need to know the maximum power of your amplifier to optimize your sound.

• You can vary the impedance parameter by connecting midrange speakers: in series, in parallel or mixed. Please select a suitable midrange speaker connection scheme depending on the number of speakers to be connected through the speaker system and the stability of the amplifier impedance.

• The most important thing when connecting speakers is to make the connection so that none of the speakers is overloaded. Overloading will damage the speaker. It is important to understand that a speaker can be supplied with power either less than or equal to the rated power for which it is designed. Otherwise, any speaker will fail due to overload. Before connecting the speakers, you need to determine their rated power (W), the active resistance of the voice coil (Ohm), which are indicated on the magnet or in the technical specifications in the attached instructions.

INSTALLATION

The installation of ACV HYBRID midrange speakers requires the help of a professional installation center. This user manual only presents the basic rules for connecting midrange speakers and technical specifications.

SELECTING SPEAKER LOCATIONS
The choice of places where the speaker system will be installed has the greatest influence on sound quality. It is necessary to think carefully about where the speaker system will be installed. Places for installing acoustics must be of sufficient size.
It is necessary to check that due to the selected installation locations of the acoustics there is no interference in the operation of the mechanical parts and electronics of the car.

PREPARATION FOR INSTALLATION

Note: You may need the tools listed below:

• Hacksaw, electric hacksaw
• Standard screwdriver set
• Insulation stripping pliers
• Crimping tool and needle nose pliers
• Silicone sealant (for acoustic cabinet), sealing pad (for speakers)

INSTALLATION IN A DOOR
Before proceeding with the installation of speakers in a car door, please check its design and window operation. The car door has a stabilizing lock bar, which is located between the door and the door arch. The locking bar prevents the door from being opened unnecessarily.

INSTALLATION IN A REAR CAR BODY
Before installing speakers in the rear car body, please check the operation of the trunk suspension springs or tension rods. The rods drive in while opening the trunk. Do not install the speakers too close to the rear glass, otherwise it will have to be removed when you screw in the screws.

INSTALLATION OF MIDRANGE

1. Choose a place to install the speaker. Make sure the mounting surface is flat and fits the speaker’s mounting dimensions. Installing the speaker on an uneven surface will damage the speaker.
2. Make sure that the selected location for installing the speaker does not interfere with the operation of the car.
3. Cut the template from the package. Place the template on the mounting surface where the speaker is to be installed and trace around it with a pencil.
4. Make a hole for the speaker. The hole can be made both with the help of tin snips, and with the help of an electric hacksaw.
5. Speaker wire (not included) must be connected to the speaker.
6. Use an insulating sleeve for the speaker wire when pulling through thin sheet metal, otherwise the wire may be damaged by the metal edges of the hole.
7. Make holes with a 1/8″ (3mm) drill bit.
8. Pull the speaker wire through the hole made and connect to the speaker. Observe polarity when connecting speakers. Mount the speakers using the screws (not included).

RECOMMENDED CROSSOVER SETTINGS

For optimum performance, it is recommended to adjust the crossover as recommended below.

NOTE: CROSSOVER SETTINGS VARY BY SPEAKER SIZE

For the NF-165HY (165mm) speaker, set the crossover high-pass filter to lS0Hz and the low-pass filter to SkHz when connected to 3-way, or set the crossover high-pass filter to lS0Hz when connected to 2-way. The slope of each crossover should be 12dB per octave or higher.

For NF-200HY (200mm) speaker, set crossover HPF to 120Hz and LPF to SKHz when connected to 3-way, or set crossover HPF to 120Hz (HPF) when connected to 2 lanes. The slope of each crossover should be 12dB per octave or higher.

RECOMMENDED ENCLOSURES

The electro-acoustic parameters of the ACV HYBRID series are optimized for installation in a car door. You can also install the speakers in a closed acoustic enclosure.

WARNING

1. Recommended speaker cabinet volume (Vee) 5.5 liters = true total volume 5.5 liters;
2. We recommend using an ACV carpet to cover the body.
3. If you will be installing multiple speakers, use only speakers of the same model, each speaker must be in its own separate enclosure.

Dimensions: it is necessary to choose a small acoustic enclosure in accordance with the recommended data in the table. This will save space in the car.

Features: If you follow our recommendations, you will achieve optimal sound quality.

SELECTING CORRECT SPEAKER WIRE

Power wires are of great importance because they directly affect damping factor and sound quality; The table below lists the recommended power wire diameters for speaker connections, which should match the applicable power and connection length ..

The table above shows continuous power at a load of 4Ohm. When the load decreases, the wire size (AWG) must be increased in proportion to the load.
