Replacing speakers with ŠKODA A5 (including models Octavia A5 and Superb A5) is a problem that owners face after 5-7 years of operation. A standard speaker system loses clarity at high frequencies, wheezing or a complete absence of sound appears in one of the channels. The reasons can be different: from natural wear and tear to moisture ingress through the door seals. But regardless of the problem, upgrading the acoustics is one of the most effective upgrades for cabin comfort.

In this article we will look at all stages of replacement: from diagnosing faults to fine-tuning the sound after installing new speakers. You will find out what brands and models suitable for ŠKODA A5 without modifications, how to avoid mistakes when dismantling and why even budget speakers can sound better than standard ones if installed correctly. And for those who are afraid of damaging the wiring, we brought unique connector pinout diagram specifically for the A5 platform, which is not in the standard manuals.

Signs of bad speakers: when is it time to change them?

The first signal about problems with acoustics is sound distortion at medium and high frequencies. If you notice that the voices of announcers or vocals in music have begun to “mumble”, and the bass has disappeared or, conversely, is too loud and “dirty” - this is a sure sign of wear on the speakers. They suffer especially often front full range speakers (size 16-17 cm), since they work in the widest range.

Other symptoms:

  • 🔊 Wheezing or crackling when the volume increases - indicates damage to the diffuser or coil.
  • 🔇 No sound in one channel (for example, the left front speaker does not work) - the wire may break or the speaker itself may fail.
  • 💧 Constant humidity inside the speaker (visible through the protective mesh) - a sign of a violation of the door seal.
  • 🎛️ Spontaneous sound change when driving over uneven surfaces, this indicates poor fastening or wear of the suspension.

It is important to distinguish between speaker problems and malfunctions head unit or amplifier. For example, if distortion appears in all speakers at the same time, the radio is most likely to blame. And if only in one channel - 90% probabilitythat it's a matter of dynamics.

Choosing speakers for the ŠKODA A5: sizes, brands and budget

On the platform A5 (including Octavia A5, Superb A5 and Yeti) speakers of the following sizes are used:

  • 🔈 Front wide: 16.5 cm (6.5 inches) is standard on most trim levels.
  • 🔈 Rear wideband: 13 cm (5.25 inches) or 16.5 cm (depending on year of manufacture).
  • 🔊 Twitter (high-frequency): 2.5-3.5 cm - installed in the A-pillars or mirrors.
  • 🔇 Subwoofer (optional): 20-25 cm - in the trunk or under the seat (in premium versions).

When choosing new speakers, pay attention to planting depth and power. For example, for front 16.5 cm speakers, the maximum depth of the basket is 60 mm (for Hertz DCX 165.3 or Focal Access 165CA1). If you take the speakers deeper, they will rest against the window lift mechanism.

Brand/Model Size Power (RMS) Frequency range Price (average)
Hertz DCX 165.3 16.5 cm 60 W 55 Hz – 22 kHz ~8,000 rub.
Focal Access 165CA1 16.5 cm 60 W 60 Hz – 21 kHz ~9,500 rub.
Alpine S-S65C 16.5 cm 80 W 65 Hz – 29 kHz ~7,200 rub.
Pioneer TS-A1670F 16.5 cm 30 W 35 Hz – 32 kHz ~4,500 rub.
Morel Tempo Ultra 602 13 cm 70 W 70 Hz – 22 kHz ~12,000 rub.

Suitable for budget replacement Pioneer or JBL (series GTO). If you strive for studio sound, pay attention to Focal or Morel - they require a high-quality amplifier, but provide incredible detail. And for lovers of powerful bass, we recommend a combo: front Hertz + subwoofer JL Audio 10W0v3 in the trunk.

💡

Before purchasing, check the compatibility of the speakers with your radio. If its power is less than 20 watts per channel, choose low-impedance models (2 ohms instead of the standard 4 ohms) for better sound.

Tools and preparation: what you need for replacement

For dismantling and installing speakers on ŠKODA A5 you will need:

  • 🔧 Screwdriver set: cross (PH2), flat, torx (T20, T25).
  • 🔨 Plastic spatulas to remove the trim (so as not to damage the clips).
  • 🔌 Soldering iron or crimp terminals (if you have to repair the wires).
  • 📏 Vernier caliper for measuring seats.
  • 🧲 Magnet (so as not to lose the screws in the doorway).
  • 🎧 Tester or multimeter to check wiring integrity.

Also prepare new speakers, sound insulation (for example, StP A2), sealant for compaction (if you modify the seats) and heat shrink tubing to isolate connections. If you plan to change tweeters, take wire with a cross section of 1.5-2 mm² to connect them.

Disconnect the battery (remove the negative terminal)|

Take a photo of the wire location before unplugging|

Check new speakers for resistance (should be 3.5-4.5 ohms)|

Prepare a workplace (preferably in a garage with good lighting) -->

⚠️ Attention: On ŠKODA A5 with the system Parktronic In the rear bumper, when removing the door trim, the door open sensor may be triggered. To avoid errors on the dashboard, before starting work turn on the ignition → open/close the door 3 times → turn off the ignition. This will reset the error in the comfort unit memory.

Step-by-step instructions: how to remove old speakers

Let's start with front speakers, since replacing them is more difficult due to the need to remove the door trim. Follow the algorithm:

  1. Remove the decorative door handle trim (pry it off with a plastic spatula from the lock side). There's a screw hidden underneath Torx T20.

  2. Unscrew the screws:

    • 1 screw under the door handle;
    • 2 screws at the bottom of the casing (under the plastic plugs);
    • 1 screw in the door pocket (remove the pocket cover by pulling up).

  3. Detach the clips along the perimeter of the casing. Start from the top corner, carefully prying with a spatula. Be careful - the clips are fragile, especially after 10 years of use.

  4. Disconnect the connectors:

    • speaker connector (white or gray);
    • power window control unit connector (black);
    • backlight connector (if available).

  • Remove the speaker. It is secured with 4 screws Torx T25. After removal, check the condition of the rubber seal - if it has hardened, replace it with a new one (for example, from Dynamat).

    • For rear speakers the algorithm is simpler:

    1. Remove the plastic cover in the trunk (it has clips).
    2. Unscrew 3 screws Torx T20holding the speaker.
    3. Disconnect the connector and remove the speaker.

    How to remove door trim without damage?

    If the clips do not yield, heat them with a hairdryer (temperature 50-60°C) - the plastic will become more elastic. Do not pull the trim sharply: first release the upper part, then the lower one. The Door A5 has a hidden screw under the speaker trim (if it has one) - don't forget to unscrew it!

    After dismantling, inspect seat. Dust and moisture often accumulate there, which accelerates corrosion. Clean it up alcohol solution and apply a thin layer anti-corrosion lubricant (for example, Liqui Moly Kupfer-Spray).

    Installing new speakers: nuances and mistakes

    Before installing new speakers check their resistance multimeter. It should correspond to the standard one (usually 4 ohms). If the resistance is lower (for example, 2 ohms), make sure that your radio can support this load - otherwise you risk burning the amplifier.

    Installation procedure for front speakers:

    1. Connect the wires to the new speaker, observing the polarity (+ to +, − to −). On ŠKODA A5 red wire - positive, black or brown - minus.

    2. Install the speaker into the seat and secure with screws. Do not overtighten them - a force of 1.5-2 Nm is enough, otherwise you can deform the basket.

    3. Apply sealant around the perimeter of the speaker for sealing (for example, Soudal Fix All). This will prevent moisture from entering and improve acoustics.

    4. Reinstall the trim in reverse order. Before fixing the clips, check the operation of the window regulator and control buttons.

    For rear speakers the process is similar, but there is a nuance: if you install 16.5 cm speakers instead of the standard 13 cm ones, you will have to modify the seat. To do this:

    • Widen the hole Bulgarian or hacksaw for metal (leaving a margin of 1-2 mm).
    • Strengthen the edges epoxy resin or metal profile.
    • Use adapter rings (for example, from Dynamat) if the speaker does not fit tightly.
    ⚠️ Attention: On Octavia A5 with the system Canton (optional 9V6) the rear speakers are connected through an amplifier in the trunk. If you change them to more powerful ones (over 50 W RMS), necessarily check whether the standard amplifier can withstand the new load. Otherwise, it will have to be replaced or an additional one installed.
    💡

    Even budget speakers will sound better than standard speakers if you properly seal the seat and use sound insulation. For example, Pioneer TS-A1670F after installation with StP A2 they sound no worse Focal without modifications.

    Sound adjustment after replacement: from balance to equalizer

    After installing new speakers don’t rush to turn on the music at full volume. First do running-in for 10-15 hours at medium volume (no more than 60% of maximum). This will allow the diffuser and suspension to “break in”, which will extend its service life.

    Next, start setting up:

    1. Balance and fader. In the radio menu (Settings → Sound → Balance) set neutral values (all sliders in the center). Then adjust by listening to music from different places in the cabin.

    2. Equalizer. For ŠKODA A5 optimal settings:

      • 60 Hz: +2 dB (for bass);
      • 250 Hz: 0 dB (mid frequencies);
      • 1 kHz: -1 dB (to remove “dirt” in vocals);
      • 10 kHz: +1 dB (for high frequency clarity).

  • Crossover (if any). For a component system, set the crossover frequency to 3-3.5 kHz for the tweeters and 80-100 Hz for the subwoofer.

    • If after replacing the speakers the sound becomes "metallic" or too bright, the problem may be:

    • 🔊 Wrong polarity (check the wire connections).
    • 🔧 Lack of sound insulation (add StP or Accent on the door).
    • 🎛️ Uncalibrated amplifier (you need to configure gain control).

    For fine tuning, use test tracks:

    • 🎵 "Sweep Tone" (from 20 Hz to 20 kHz) - to check the frequency range.
    • 🎵 "Pink Noise" — to balance the volume between channels.
    • 🎵 "Bass Test 30Hz" - to assess the quality of bass.

    Common mistakes and how to avoid them

    Even experienced car owners make mistakes when replacing speakers with ŠKODA A5. Here are the most common:

    1. Ignoring polarity. If you confuse + and −, the sound will become “flat” and the bass will disappear. On A5 Polarity can be determined by the color of the wires or markings on the connector (a dot or stripe indicates +).

    2. Poor sealing. Without a speaker seal, air will “walk” between the passenger compartment and the door, which worsens the sound. Use entrusted rings or sealant.

    3. Overload of standard wiring. Powerful speakers (over 60W RMS) require thick wires. If you heard crackling noise at high volume, this is a sign of a voltage drop. The solution is to lay new wires with a cross-section of 2.5 mm².

    4. Failure to take into account the acoustic volume of the door. Doors ŠKODA A5 have a small internal volume, which affects the bass. If after replacement there are fewer of them, install podiums (for example, from Dynamat) or modify the door cards.

    Another typical problem is noise when the speakers are working (for example, crackling noise when driving over uneven surfaces). This talks about:

    • 🔧 Poor fastening (check the tightness of the screws).
    • 🔌 Short circuit in the wires (use a multimeter in the “test” mode).
    • 💧 Moisture ingress (you need to blow dry and process WD-40).
    ⚠️ Attention: On Superb A5 with the system Dynaudio (optional 9V7) replacing the speakers without modifying the amplifier will lead to automatic mute in 5-10 minutes. This is protection against abnormal load. The solution is to flash the amplifier or install linear converter.
    Is it possible to install larger speakers than stock ones?

    Yes, but with modifications. For example, instead of the standard 13-centimeter rear speakers, you can install 16.5-centimeter ones by widening the hole. However this requires:

    • Strengthening the metal (so that it does not vibrate).
    • Replacing the wiring with a thicker one (if the power of the new speakers is above 50 W).
    • Amplifier settings (if any).

    Best options for upgrade: Hertz DCX 165.3 or Alpine S-S65C.

    How to check if the speaker is working without removing the casing?

    There are 3 ways:

    1. Connect tester with signal generator function to the speaker connector (remove it from the back of the casing). If the speaker makes sound, it is working.

    2. Turn on the music and press your hand against the speaker through the casing. If you feel vibration, the speaker is working.

    3. Use endoscope (or a phone with a flex cable) to inspect the diffuser for damage.

    If the speaker makes no sound, check:

    • Integrity of wires (multimeter).
    • Radio settings (the channel may be disabled).
    • Fuse (on A5 it's in the block SC29, 10A).
    Do I need to change the tweeters when replacing the main speakers?

    Not required, but recommended. Staff tweeters at ŠKODA A5 have a limited frequency range (up to 18 kHz), while high-quality models (for example, Morel Maximo) reproduce up to 22 kHz. This adds detail in vocals and instruments.

    If your budget is limited, you can leave standard tweeters, but:

    • Disable them via crossover (if the new speakers have it).
    • Or reduce the treble level on the radio (EQ → 10 kHz: -2 dB).
    Which amplifier is suitable for upgrading the acoustics on the A5?

    For ŠKODA A5 4-channel amplifiers with a power of 60-100 W per channel are optimal. Top 3 options:

    1. Alpine KTA-450 — compact, connects to the standard radio, power 45 W × 4.

    2. Hertz HDP 4 - 75 W × 4, supports high-impedance load (suitable for component systems).

    3. Audison AP 4.9 bit — premium version with DSP (digital sound processing), 100 W × 4.

    To connect you will need:

    • Interconnect cable (RCA).
    • Power wire (cross section 4-6 mm²).
    • Linear converter (if the radio does not have RCA outputs).
    Is it possible to repair a speaker yourself if it wheezes?

    Yes, but only if the problem is:

    • Dust on the diffuser - gently clean with a brush.
    • Suspension wear - apply rubber glue (for example, Loctite 406).
    • Oxidation of contacts - clean and solder the connections.

    If damaged voice coil or diffuser, repair is impractical - it’s cheaper to buy a new speaker. The average cost of repairs in the service (replacement of the suspension + centering) is 3,000-5,000 rubles, which is comparable to the price of a budget model (Pioneer TS-A1670F).
