Owners Ε KODA Octavia TUR We are often faced with the question: how to improve the sound of a standard audio system? Even in top-end configurations, factory acoustics do not always satisfy music lovers - the bass booms, the high frequencies hurt the ear, and the mid frequencies disappear in the road noise. At the same time speaker replacement - one of the most effective ways to transform the sound of a cabin without a complete overhaul.

In this article we will analyze all aspects of working with Octavia TUR acoustics: from analysis of standard speakers to selection of components for upgrade. Let's consider unique soundproofing features of this model (for example, the effect of door shape on acoustics) and give step-by-step instructions for replacing it yourself. And also - we will compare popular brands of speakers in terms of price/quality ratio especially for Octavia TUR.

Octavia TUR standard audio system: what's inside?

Depending on the year of manufacture and configuration, Ε KODA Octavia TUR equipped with different audio systems. Basic versions (eg Swing or Bolero) receive 6–8 speakers with an amplifier with a power of up to 20 W per channel. Top (Amundsen or Columbus) - up to 10 speakers + subwoofer, and in Octavia RS the system may stand Canton with digital processor.

The key problem of standard acoustics is uneven frequency distribution. For example, front full-range speakers (usually 165 mm) can't handle lower bass 80 Hz, and rear coaxial (130 mm) β€œflood” the high frequencies. At the same time, the doors often lack proper sound insulation, which aggravates the situation.

  • πŸ”Š Front acoustics: full range speakers 165 mm (sometimes with a separate tweeter in the mirrors or on the dashboard).
  • πŸ”Š Rear: coaxial speakers 130 mm (in a shelf or door).
  • πŸ”Š Subwoofer: only on top trim levels (usually under the trunk floor).
  • πŸ”Š Amplifier: built into the radio or external (in Canton).
⚠️ Attention: B Octavia TUR 2018+ included Style and Sportline the system may stand BeatsAudio with branded speakers. Replacing them will require adapters for connection!

How to choose replacement speakers: key parameters

When choosing new acoustics for Octavia TUR take into account three critical factors:

  1. Size: front speakers - 165 mm (6.5"), rear - 130 mm (5.25"). In some modifications it is possible 178 mm (7") front.
  2. Type: coaxial (2-3 way) or component (with separate tweeter). For Octavia TUR Component systems are optimal - they give the best scene.
  3. Sensitivity: not lower 90 dB (otherwise you will need an external amplifier).

Leading among brands Focal, Hertz, Morel and Alpine. For example, Focal PS 165 (component system) fits perfectly into the front doors, and Hertz DCX 130.3 - to the rear. For bass you can add JL Audio 10W3v3 (10-inch subwoofer) in the trunk.

Brand/Model Type Sensitivity (dB) Power(RMS) Price (β‰ˆ)
Focal PS 165 Component (6.5") 91 80 W 22 000 β‚½
Hertz DCX 130.3 Coaxial (5.25") 93 100 W 15 000 β‚½
Morel Tempo Ultra 602 Component (6.5") 90 120 W 28 000 β‚½
Alpine S-S65 Coaxial (6.5") 88 80 W 12 000 β‚½
⚠️ Attention: B Octavia TUR with the system Canton The standard amplifier has non-standard connectors. Connecting new speakers will require a lineman or amplifier replacement!

Before purchasing, check the depth of the seat in the doors - in some modifications Octavia TUR it is limited to 60 mm.

Step-by-step instructions for replacing speakers

To replace the front speakers in Octavia TUR you will need:

  • πŸ”§ Screwdriver set (TORX T20/T25, Phillips).
  • πŸ”§ Plastic spatulas for removing trim.
  • πŸ”§ Soldering iron or terminals for connecting wires.
  • πŸ”§ Speakers with transition frames (if needed).

Algorithm of actions:

  1. Remove the door card (start with the clips at the bottom, then unclip the top latches).
  2. Unscrew the stock speaker (4 bolts).
  3. Disconnect the connector, solder new wires or use an adapter.
  4. Install the new speaker, secure it and test the sound before assembling the casing!

β˜‘οΈ Preparing to replace the speakers

Done: 0 / 5

For rear speakers the process is similar, but in some modifications Octavia TUR You will need to remove the trunk shelf. In models with BeatsAudio Connectors may be non-standard - use the connection diagram for your year of manufacture.

What to do if the speaker does not fit?

In some cases, the door seat Octavia TUR has a depth limitation. Solutions:

- Use speakers with a neodymium magnet (they are more compact).

- Install spacers (but this will worsen sound insulation).

- Modify the metal of the door (requires welding).

Noise insulation: why is it important for sound

B Ε KODA Octavia TUR factory door sound insulation is often absent or made of thin material. This leads to the fact that the speakers β€œplay” not into the interior, but into the metal of the door, losing up to 30% of the sound. The solution is to install vibration absorbers (for example, StP A2) and sound absorbers (Bitoplast).

Optimal sound insulation scheme for Octavia TUR:

  1. Paste StP A2 (2–3 mm) on the inside of the door (vibration absorption).
  2. Add a layer Bitoplasta (10 mm) to the outside of the speaker (sound insulation).
  3. Seal all service openings in the door (for example, with sealant).

Soundproofing effect:

  • πŸ”Š Improvement of bass by 20–40% (they stop β€œmumbling”).
  • πŸ”Š Clearer high frequencies (no metal resonance).
  • πŸ”Š Reduced external noise in the cabin.
⚠️ Attention: When covering doors with sound insulation, make sure that the materials do not block the drainage holes - this will lead to moisture accumulation and corrosion!

Adjusting the sound after replacing speakers

Even the best speakers will sound bad without the right setup. B Octavia TUR with systems Amundsen/Columbus An equalizer is available, but its capabilities are often insufficient. Solutions:

  • πŸŽ›οΈ External processor (for example, DSP from Helix) - allows you to more accurately adjust frequencies.
  • πŸŽ›οΈ Amplifier with adjustments (for example, Alpine KTA-450).
  • πŸŽ›οΈ Software setup through VCDS (for systems Canton).

Basic equalizer settings for Octavia TUR:

  • 60 Hz: +2 dB (for bass).
  • 250 Hz: 0 dB (mid frequencies).
  • 10 kHz: -1 dB (high smoothing).
πŸ’‘

After replacing the speakers, be sure to check the phasing (polarity) - incorrect connection leads to β€œdips” in the sound.

Audio system tuning: from simple to complex

If replacing your speakers isn't enough, consider a comprehensive upgrade:

  1. Subwoofer installation: optimal - 10–12" in a closed enclosure (for example, JL Audio 10TW3).
  2. Replacing the radio: on Pioneer AVH-Z9200DAB or Alpine iLX-F411 (with support Apple CarPlay/Android Auto).
  3. Multichannel amplifier: for example, Audison AP 8.9 bit for a complete system.

Example budget for a full upgrade:

Component Model Cost (β‰ˆ)
Front acoustics Focal PS 165 22 000 β‚½
Rear speakers Hertz DCX 130.3 15 000 β‚½
Subwoofer JL Audio 10W3v3 30 000 β‚½
Amplifier Alpine MRV-F300 25 000 β‚½

For Octavia TUR with the system Canton a β€œsoft” upgrade is possible: replacing only the front speakers + adding a subwoofer. This will give an increase in sound without losing factory functions (for example, 3D sound).

Typical mistakes when upgrading an audio system

Many owners Octavia TUR make mistakes that spoil the sound or lead to breakdowns:

  • ❌ Ignoring polarity: Incorrect connection (β€œ+” to β€œβ€“β€) results in unbalanced sound.
  • ❌ Saving on wires: thin cables create power losses (use copper with a cross-section of at least 2.5 mmΒ²).
  • ❌ Lack of customization: Even expensive speakers will sound bad without the right EQ.
  • ❌ Overload of standard wiring: Amplifier power >100 W requires separate battery power.
⚠️ Attention: B Octavia TUR with the system BeatsAudio When replacing speakers, an error may occur in the on-board computer. The solution is to flash the radio firmware or install a load emulator.

FAQ: Frequently asked questions about speakers in Octavia TUR

Is it possible to install 178 mm (7") speakers instead of the standard 165 mm ones?

Yes, but the seat will need modification (boring or spacers). In some modifications Octavia TUR (for example, RS) the front doors are already adapted to 178 mm.

Do I need to change the amplifier when replacing speakers?

If the sensitivity of the new speakers is higher 90 dB, a standard amplifier may be enough. But for powerful systems (for example, Morel Tempo) it is better to add an external amplifier.

How to check speaker polarity?

Connect the battery 9V to the speaker terminals - if the cone moves forward, the polarity is correct. B Octavia TUR standard pinout: red - β€œ+”, black - "-".

Which is better: component or coaxial acoustics?

For Octavia TUR optimal component system (separate tweeter and midbass) - it gives the best scene. Coaxial speakers are easier to install, but lack quality.

How to improve sound without replacing speakers?

Options:

  • Add soundproofing to the doors.
  • Install a sound processor (for example, DSP).
  • Replace the radio with a model with a better DAC (for example, Sony XAV-AX5000).
