Standard speaker system Škoda Kodiaq even in top trim levels it often leaves much to be desired - especially if you value high-quality sound. Weak bass, distortion at high volumes and lack of detail in the midrange make owners consider upgrading. But how to choose the right speakers without damaging the car's electrical system? And is it possible to cope with the installation yourself, without resorting to the services of a car service?

In this guide we will look at all stages of acoustics replacement - from analysis of the standard system to the intricacies of connecting new components. You will learn which speaker sizes are suitable for Kodiaq different years of manufacture, how to avoid mistakes when dismantling panels and which brands offer the best price/quality ratio. And for those who are planning a complete rework of the audio system, we have prepared unique data on compatibility with external amplifiers and subwoofers, which are not in the standard instructions.

Analysis of standard Škoda Kodiaq acoustics: weaknesses and upgrade opportunities

Standard audio system Kodiaq (even in version Canton) has several critical disadvantages:

  • 🔊 Front speakers (16.5 cm) - insufficient power and poor performance at low frequencies due to a weak magnet.
  • 🔊 Twitter — in basic configurations they are not available at all, in Canton 2.5 cm models with mediocre detail are installed.
  • 🔊 Rear speakers (16.5 cm or 20 cm depending on the configuration) - often overloaded due to incorrect crossover settings.
  • 🔊 Amplifier — the standard system does not have an external amplifier, which limits the potential of even high-quality speakers.

The main problem is incorrect load distribution. head unit (even Amundsen or Columbus) is not able to fully control low-impedance speakers, which is why the sound “flattens” at high volumes. The solution is either installing an external amplifier or replacing the speakers with models with impedance 4 ohms (standard - 2 ohms).

Sizes and types of speakers for Kodiaq: what fits without modifications

One of the key questions is what speakers can be installed without modifying the seats?. B Kodiaq (2017–2026) the following standards are used:

Location Standard size (diameter) Seat depth Recommended upgrade
Front doors (bottom) 16.5 cm (6.5") up to 65 mm 16.5 cm with neodymium magnet (eg Focal IS 165)
Front tweeters 2.5 cm (1") or none up to 30 mm 2.5–3 cm silk domes (e.g. Morel Maximo)
Rear doors 16.5 cm or 20 cm (depending on configuration) up to 70 mm 20 cm coaxial (eg JBL Club 9603)
Center channel (optional) — — 3.5–4" wideband (installed in the dashboard)

⚠️ Attention: In cars with the system Canton the rear speakers are the size 20 cm, but the seat allows you to install and 16.5 cm with adapter rings. However, this will degrade the bass potential.

For those who are planning to install a subwoofer, the best option is 8–10" models in a closed case (for example, Alpine S-W10D4). They fit into the niche behind the rear seat without losing useful space.

💡

Before purchasing speakers, check the depth of the seat in your Kodiaq — in some trim levels it may differ by ±10 mm due to additional sound insulation.

Selecting speakers: overview of brands and models for Kodiaq

The car audio market offers hundreds of models, but not all are suitable for Škoda Kodiaq in terms of price/quality ratio. We tested several options and identified the best:

  • 🏆 Premium segment:
    • Focal IS 165 - ideal for front doors, excellent detail and bass.
    • Morel Tempo Ultra 692 — coaxial speakers with titanium tweeters.
  • 💰 Average price range:
    • JBL Club 9603 — the best choice for rear doors (20 cm).
    • Alpine S-S65 — balanced sound, suitable for front doors.
  • 💵 Budget options:
    • Pioneer TS-A1670F - inexpensive, but noticeably better than standard ones.
    • Kicker 43DSC6504 - good bass for its price.

⚠️ Attention: When choosing speakers, pay attention to sensitivity (dB). Optimal for systems without an external amplifier 90–92 dB. Models with lower sensitivity 88 dB will require additional reinforcement.

If you are planning an amplifier installation, you may want to consider component systems (e.g. Hertz Dieci DCX 165.3). They are more expensive, but they give much better scene due to separate tweeters and midbass.

What to do if the speakers do not fit in depth?

If the depth of the new speaker exceeds the seat, you can use spacer rings or modify the metal of the door (a welding machine is required). As a last resort, choose a model with a neodymium magnet (they are more compact than ferrite ones).

Step-by-step instructions for replacing front speakers

Replacing the front speakers is the most time-consuming process due to the need to remove the door panels. Here step-by-step algorithm taking into account the specifics Kodiaq:

  1. Removing the door card:
    • Remove the two screws at the bottom of the door (under the plugs).
    • Carefully pry the clips around the perimeter, starting from the bottom corner.
    • Disconnect the wiring connectors (first the power window control unit, then the speaker).
  2. Removing the standard speaker:
    • Unscrew the 4 screws securing the speaker to the door.
    • Disconnect the terminals, noting the polarity (usually marked red/black).
  3. Installing a new speaker:
    • Try the speaker on the seat. Use an adapter ring if necessary.
    • Connect the terminals, observing polarity.
    • Secure the speaker with self-tapping screws (do not overtighten so as not to deform the housing!).
  4. Reassembly:
    • Make sure all connectors are connected.
    • Snap the door card clips into place, starting from the top corner.
    • Tighten the screws and check the operation of the window regulator.

⚠️ Attention: B Kodiaq 2020+ door shock sensors are installed for the system Side Assist. When removing the panels, do not damage their wiring - this may cause an error on the dashboard!

After installation, test the sound at different frequencies. If there is no bass, the speaker may be installed out of phase with the rear speakers (change the polarity on one of them).

💡

The most common mistake when replacing is ignoring sound insulation. If you do not seal the holes in the door after installation, the bass will “go” into the body and not into the interior.

Rear speakers and tweeters: installation nuances

Rear speakers in Kodiaq It’s easier to replace, but there are pitfalls here:

  • 🔧 Available with Canton rear speakers 20 cm, but they can be replaced with 16.5 cm with adapters. However, this will reduce the bass potential.
  • 🔧 Tweets in Canton located in the front door pillars. To replace them, you will need to remove the plastic covers (carefully - they are fragile!).
  • 🔧 There are no tweeters in the basic configurations at all. They can be installed in standard places by drilling holes for the wires.

To connect Twitter use capacitors (for example, 2.2 µF), unless they come with speakers. This will protect them from low frequencies.

If you are installing coaxial speakers (such as JBL Club), tweeters do not need to be mounted separately - they are already built-in. However, the component system will give a better scene.

Connecting an amplifier and subwoofer: diagrams and recommendations

If you want maximum sound quality, you can’t do without an external amplifier. B Kodiaq There are two connection options:

  1. Via high-level input (from the radio):
    • Use a converter LOC (Line Out Converter) to convert the signal.
    • Connect to the rear speakers (the signal is cleaner there).
    • Adjust the input level on your amplifier to avoid clipping.
  2. Via low-level output (if the radio supports):
    • B Columbus There are standard RCA outputs (must be activated in the service menu).
    • Connect the amplifier directly, bypassing LOC.

For a subwoofer it is optimal to use monoblock amplifier (for example, Alpine MRV-M500). It can be hidden under the seat or in the trunk. Power wiring (+12V) pull from the battery through the fuse (80–100A), and the signal cable - along the standard wiring.

⚠️ Attention: When laying cables, avoid crossing wires CAN buses (they run under the center console). This may cause interference with electronics.

💡

To configure the amplifier, use test tracks with pure sine (for example, 50 Hz for a subwoofer). This will help avoid distortion.

Adjusting the sound after replacing the acoustics

Even the most expensive speakers will sound bad without the right setup. B Kodiaq this is done through the radio menu:

  1. Go to Settings → Sound → Equalizer.
  2. Disable all factory presets (eg "Jazz" or "Rock").
  3. Manually tune frequencies:
    • 60–100 Hz: Boost +2-3dB for bass.
    • 1–3 kHz: Reduce by -1–2 dB (this is the “dirty” midrange region).
    • 10–12 kHz: Raise +1 dB for air.
  • Activate Time Alignment (if available in your radio) to adjust the sound delay between the front and rear speakers.

    • If you have an external amplifier installed, additional configuration is carried out via gain (input signal level) and crossover. Recommended for front speakers HPF 80 Hz, for the subwoofer - LPF 80–100 Hz.

    Check the phasing: turn on music with clear bass (for example, a track "Bass I Love You" from Meghan Trainor) and alternate the polarity on one of the speakers. When the bass becomes as deep as possible, the phase is correct.

    FAQ: Frequently asked questions about replacing acoustics in a Škoda Kodiaq

    Is it possible to install larger speakers than stock ones?

    Theoretically, yes, but the seat will need modification. For example, instead of 16.5 cm can be entered 18 cm, but you will have to cut off part of the metal of the door and strengthen it. It is much easier to use adapter rings for 20 cm speakers in the rear doors (if standard 16.5 cm).

    Do I need to change the wiring when installing powerful speakers?

    If the power of the new speakers does not exceed 100W RMS, the standard wiring will hold up. For systems more powerful 150 W It is recommended to lay separate cables (cross section 1.5–2.5 mm²) from the amplifier to the speakers to avoid signal loss.

    How to avoid electronic errors after replacement?

    The main problem is the error triggering "Speaker short circuit" on the radio. This happens if the impedance of the new speakers is lower 2 ohm. Solution:

    • Use speakers with impedance 4 ohm.
    • Connect resistors (4–8 ohms) parallel to the speakers (temporary solution).
    • Update the firmware of the radio (in some cases this clears the error).

    Is it worth installing soundproofing?

    Definitely! Without sound insulation up to 50% bass will be dampened by door vibrations. Best option:

    • Vibroplast (2–3 mm) on the inside of the door.
    • Splen (10 mm) to the outer panel.
    • Sealing all holes mastic.

    This will not only improve the sound, but also reduce road noise.

    Which radio should I choose for a full upgrade?

    If you're replacing the entire system, consider these options:

    • Pioneer AVH-Z9200DAB - supports Apple CarPlay, Android Auto, there is RCA outputs.
    • Alpine iLX-F411 - compact, but with excellent sound and equalizer settings.
    • Sony XAV-AX5500 - good screen and built-in amplifier 4×55 W.

    To preserve standard functions (for example, Virtual Cockpit) adapter required Maestro RR.
