Owners Skoda Octavia A7 Often faced with the fact that the regular audio system ceases to suit as you accumulate experience of listening to music. Standard speakers installed from the factory are usually designed for basic playback, but fail to unlock the potential of quality music files or modern genres requiring deep bass and pure high frequencies. The problem is exacerbated by the age of the car, when under the influence of moisture, temperature changes and vibrations, the magnetic system and diffusers begin to degrade.
Understanding the design of door cards and the location of acoustic elements in the body Octavia A7 This is the first step to creating a system that will keep you happy for years. In this article, we will discuss in detail what speakers are on different trim levels, how to choose the right replacement and what nuances of installation should be taken into account so as not to damage the door cards and electronics.
Analysis of the regular acoustic system Skoda Octavia A7
The factory configuration of the sound system in Skoda Octavia A7 It depends on the level of equipment and the year of release. Basic versions usually have simple broadband speakers with a diameter of 160 mm in the front doors and 100 mm in the rear. These components are often made of cheap plastic and have minimal moisture protection, which is their main vulnerability.
More expensive equipment can be equipped with a system Chicco or Vaillant (depending on the delivery region), where the number of channels is increased by adding high-frequency tweeters in the windshield racks and a central speaker on the dashboard. However, even in these cases, the frequency range remains limited, and the power of the standard head unit is often insufficient for high-volume sound quality.
The feature of the front suspension of speakers is that they are fixed directly in the door map, and not in the metal door. This creates an acoustic junction, but requires the installation of special parcel rings when replaced with heavier aftermarket components to avoid vibrations and rattles of plastic.
The critical point is the lack of a moisture cap in many regular speakers, which leads to oxidation of contacts and rotting of the diffuser after 3-4 years of operation in a harsh climate.
Common malfunctions and diagnosis of sound
Before running to the store for new components, you need to accurately determine the nature of the malfunction. Often the problem is not the same. Skoda Octavia A7 dynamics, and in wiring or amplifier. Common symptoms include wheezing at low frequencies, a complete lack of sound in one of the doors, or distortion at maximum volume.
One of the frequent problems is the oxidation of the contacts in the detachable pad, which is located behind the door card. Moisture penetrating through drainage holes can accumulate at the bottom of the door and rise up, causing soldering to corrosion on the speaker itself.
If you hear foreign knocks, this may indicate the magnet is peeling off or the diffuser suspension is breaking down. In some cases, the problem lies in the wrong phasing of the wires, especially if the wiring was reconnected by previously inexperienced masters.
For accurate diagnosis, it is recommended to use a multimeter to check the resistance of the coil and visually inspect the diffuser for cracks or deformations. Do not ignore the check of the standard amplifier, if it is installed in your version.
- Basic (no tweets)
- Chicco/Vaillant System
- Canton system (premium)
- Don't know/No sound.
Selection of speakers for replacement: criteria and compatibility
When choosing a replacement for standard components, it is important to consider not only size, but also sensitivity, impedance and power. For Octavia A7 2-band coaxial systems with a diameter of 165 mm with a sensitivity of 90 dB are ideal, as they require less power for loud sound.
Many owners choose component systems where the tweeter is placed separately in the rack or headrest, and the LF speaker stays in the door. This allows for a significant improvement in the scene and the detail of the sound, especially in the high frequency range. However, this approach requires more complex installation and configuration.
Pay attention to the diffuser material: paper speakers give a warm sound, but are afraid of moisture, and polypropylene or composite models are more resistant to external influences, which is critical for car doors.
- ๐ก Sensitivity Choose models with an index above 90 dB to work from a regular head unit.
- ๐ Power Focus on rated power, not peak power, to avoid overload.
- ๐ Impedance The standard for autoacoustics is 4 ohms, which corresponds to the output of most amplifiers.
The installation process and nuances of installation in the door
Installation of new speakers in Skoda Octavia A7 It requires care when removing door cards, as plastic clips are quite fragile. Start by removing the screws hidden under decorative plugs in the door handle and under the armrest, then gently tuck the card with a plastic spatula.
After removing the skin, you will see a metal door with technological holes. If you are installing deep magnet speakers, you may need to refine the hole or use a plywood or plastic parcel ring to keep the diffuser from touching the metal.
It is important to run wires through the rubber corrugated in the door rack to avoid rubbing the insulation when opening and closing the door. Use quality connectors or soldering followed by thermal shrinkage for a reliable connection.
Donโt forget to install noise insulation on the metal part of the door before installing the speaker โ this will improve the quality of the bass and eliminate the resonance of the metal. It is the lack of high-quality vibration insulation in the doors that is the main reason for the โflatโ sound even after installing expensive speakers.
โ๏ธ Preparation of the door for installation
Noise insulation and acoustic preparation of door cards
Simply replacing the speakers is not enough to get a high-quality sound in the Octavia A7. The door of a car is not a closed drawer, but an open structure that works as a resonator. Without proper preparation, low frequencies will โwalkโ around the cabin, rather than being given away to the listener.
Acoustic preparation includes two stages: metal vibration insulation (a layer of bitumen material with aluminum coating) and plastic noise insulation (a layer of porous material that absorbs high-frequency noise from wind and road).
When using noise insulation materials, it is important not to overdo it with weight, so as not to increase the load on the door hinges. It is enough to process the zones around the speaker and the central part of the door, creating an improvised โacoustic bodyโ.
- ๐ Vibration isolation - is applied to the metal, reduces resonance and gives rigidity to the structure.
- ๐ฌ Noise insulation glued to the inside of the plastic card, absorbs foreign sounds.
- ๐ง Waterproofing - mandatory for the protection of wiring and new speakers from moisture.
Integration of external amplifiers and subwoofers
If the standard power is not enough to pump new speakers, you will need to install an external amplifier. V Skoda Octavia A7 The amplifier can often be placed under the seat or in the trunk, hiding the wiring under the flooring.
To connect the amplifier to a regular magnote (especially if it is a multimedia system) Amundsen or Discover Media) a special adapter is often required which converts the high-level signal to a linear signal or provides control of the switching.
Adding a subwoofer to the cabin allows you to compensate for the losses in the low-frequency range, which are inevitable when installing speakers in open doors. Compact active subwoofers under the seat do not take up much space and complement the system perfectly.
โ ๏ธ Warning: When connecting an external amplifier, be sure to use a fuse on the power supply wire near the battery to prevent fire in the event of a short circuit.
โ ๏ธ Warning: Incorrectly configuring filters (crossovers) can overload speakers and fail them, especially at low frequencies.
Difficulties of connecting to the regular Discover Media head unit
Discover Media uses a digital signal that requires the use of a line output converter to produce an analog signal to the amplifier. Direct connection can result in no sound or distortion.
Tuning of sound and setting the equalizer
After the physical installation of the equipment, the adjustment stage begins. In the menu of the multimedia system Skoda Octavia A7 Basic balance, fader and equalizer settings are available. The correct setting allows you to adjust the frequency characteristic to your preferences.
To begin with, set all the sliders of the equalizer in a neutral position and adjust the balance so that the sound is directed towards the driver. Then gradually increase the low and high frequencies until the sound is balanced and natural.
Do not get carried away by excessive bass amplification, as this can lead to distortions at medium volume and overload of speakers. The best sound is achieved with moderate settings and a quality signal source.
If you have installed an amplifier with your own settings, use them instead of the equalizer of the head units to avoid double signal processing and loss of quality.
| Component | Recommended size | Power (RMS) | Sensitivity |
|---|---|---|---|
| Front doors | 165 mm (6.5 inches) | 50-80 W | 90-92 dB |
| Rear doors | 130 mm (5.25 in) | 40-60 W | 88-90 dB |
| Tweeting | 20-25 mm | 20-40 W | 92+ dB |
| Subwoofer | 10-12 inches | 150-300 watts | 88-90 dB |
Conclusion and final recommendations
Modernization of the acoustic system in Skoda Octavia A7 It is a process that requires not only financial investment, but also technical knowledge. Properly selected components, high-quality installation and competent tuning can turn a standard car into a real music salon.
Donโt forget the importance of noise insulation and moisture protection, as these factors directly affect the durability of your new acoustics. Experiment with different speaker models, but always prioritize reliability and quality of materials.
Remember that sound is a subjective experience, so the best way to find the perfect solution is to listen to the speakers before you buy, if you have the opportunity.
Before starting work on dismantling door cards, be sure to turn off the battery's minus terminal to avoid short circuits in the car's electrical wiring.
High-quality vibration insulation of the door is the foundation for pure sound, without which even the most expensive speakers will not reach their potential.
Can you install larger speakers in the door of the Octavia A7 without modifications?
Most speakers of the same size can be fitted in regular 165mm holes, but if you want to put a 160mm or 165mm deep magnet, it often requires making a parcel ring or fitting the seat so that the diffuser does not touch the glass or metallic elements of the door.
Do I need to make noise insulation when replacing regular speakers?
While technically not necessary, without soundproofing, you wonโt get quality bass and pure sound. The door works as a resonator, and vibration insulation will greatly improve sound and kill extraneous noises, making the music more detailed.
What is the power voltage of the standard speakers Skoda Octavia A7?
The standard radio transmitter produces a high-level signal that is directly fed to the speakers. Voltage varies depending on the volume and power of the amplifier, but the standard impedance of the speakers is 4 ohms. When external amplifiers are connected, signal conversion may be required.
Where is the best place to place a subwoofer in the Octavia A7?
The most popular seat is under the front passenger seat for compact active subwoofers. This saves space in the trunk and ensures good sound integration. It is also possible to install in the niche behind the back of the rear seat or in the box in the trunk for more powerful models.
