Standard audio system Nissan Almera Classic: what's inside and why she doesn't play well

Standard Almera Classic equipped with audio preparation with 4 speakers: two in the front doors (size 16.5 cm) and two in the rear shelf (13 cm). In top versions, tweeters were added in the A-pillars. However, even in the maximum configuration the sound remained mediocre. Why?

The main problems of the standard system:

  • 📉 Poor quality speakers: Paper cones wear out quickly, especially at high volumes.
  • 🔊 No amplifier: The radio feeds the speakers directly, which leads to distortion in the midrange.
  • 🚪 Poor sound insulation of doors: vibrations from the speakers are weakly damped, the sound becomes “dull”.
  • 🎚️ Lack of equalizer: even in radios with CD/MP3 There is no way to fine-tune the sound.

In addition, wiring in Almera Classic is often too thin for high-power speakers, which can lead to overheating of contacts or even fire when installing speakers with lower impedance 4 ohm. We'll talk more about this in the section on errors.

📊 What kind of radio do you have in your Nissan Almera Classic?
  • Standard (cassette/CD)
  • Standard with MP3
  • Last (2-DIN, with screen)
  • Installed a radio from another car

Which speakers are suitable for Nissan Almera Classic: sizes and types

Before you buy new speakers, you need to know them exactly size and type of fastening. B Almera Classic The following standards are used:

Location Size (diameter) Planting depth Mounting type
Front doors 16.5 cm (6.5") Before 60 mm 3 or 4 bolt
Rear shelf 13 cm (5.25") Before 50 mm Snap-on or 2 bolts
Tweeters (in stands) 2.5–3.5 cm Before 20 mm Glue or screws

Important: in some trim levels the rear speakers may be 10 cm - check this before purchasing! To do this, just remove the rear parcel shelf trim (it is held on by clips).

By type of dynamics they are divided into:

  • 🔘 Coaxial (2- or 3-way) - easier to install, suitable for replacing standard ones without modifications.
  • 🔘 Component - require separate installation of midbass and tweeters, but provide better sound.

For most owners Almera Classic the optimal choice would be coaxial speakers with sensitivity no lower 90 dB and power 50–80 W RMS. If you're willing to spend time on soundproofing and wiring, a component system will give you more spacious sound.

💡

When choosing speakers, pay attention to impedance (resistance). For standard wiring Almera Classic safe speakers with 4 ohm. Speakers with 2 ohm may overload the radio or amplifier.

Step-by-step instructions for replacing speakers in Nissan Almera Classic

Replacing the front speakers takes approx. 1.5–2 hours, rear - up to 1 hour. You will need:

  • 🔧 Phillips and flat screwdriver.
  • 🔨 Plastic spatulas for removing trim.
  • 🔌 Soldering iron or terminals for connecting wires.
  • 🧲 Magnet for finding fallen bolts.

Remove the terminal from the battery (to avoid short circuit)|

Prepare new speakers and transition frames (if needed)|

Check the complete set (bolts, wires, seals)|

Clean the installation site from dust and debris -->

Replacing front speakers

1. Remove the plastic trim on the door handle (pry it up with a spatula from below).

2. Unscrew two bolts under the trim and one bolt at the bottom of the door (under the speaker).

3. Carefully remove the door trim, starting from the bottom corner. Be careful with clips!

4. Disconnect the connector from the standard speaker and unscrew the 3 mounting bolts.

5. Install the new speaker, connect the wires (observe the polarity!) and reassemble everything in reverse order.

Replacing rear speakers

1. Open the trunk and remove the rear parcel shelf trim (held on by 4 clips).

2. Unscrew the two speaker mounting bolts or press out the latches (depending on the configuration).

3. Disconnect the connector and install a new speaker. In some cases, you will need to modify the seat with a knife or file.

⚠️ Attention: If you have a radio with an amplifier (for example, Bose in top versions), before replacing speakers be sure to turn off the amplifier - otherwise you risk burning the new speakers!

What should I do if the new speaker does not fit into the seat?

B Almera Classic Sometimes a problem occurs when the diameter of the new speaker is slightly larger than the standard one. In this case:

1. Carefully file the edges of the hole.

2. Use an adapter frame (available at auto stores).

3. If the speaker is deeper than standard, modify the inside of the door (remove any interfering plastic ribs).

Adjusting the sound after replacing speakers

Even the most expensive speakers will sound bad if they are not tuned. B Nissan Almera Classic There are several ways to improve the sound:

1. Setting up via radio

If you have a standard radio with CD/MP3, go to the sound settings menu (usually the button AUDIO or SOUND). Here you can adjust:

  • 🎛️ Balance (front/back).
  • 🎛️ Fader (left/right).
  • 🎛️ Equalizer (if any): increase 100–150 Hz for bass and 10–12 kHz for tall ones.

In aftermarket radios (for example, Pioneer or Sony) advanced settings available, including Time Alignment (delaying the sound to create the scene) and Crossover (frequency separation).

2. Setting up with an amplifier

If you have installed an amplifier, please note:

  • 🔊 Gain level (do not set it to maximum - this will lead to distortion!).
  • 🔊 Crossover frequency: for front speakers usually 80–100 Hz, for subwoofer 80 Hz.
  • 🔊 Phase: If the bass booms, try changing the polarity on the subwoofer.

⚠️ Attention: If, after installing an amplifier, the speakers begin to “wheeze” at high volumes, check on-board voltage. B Almera Classic drawdown is common 11–12 V when the air conditioner is turned on, which leads to distortion. The solution is to install a capacitor or a second battery.

3. Sound insulation of doors

Without soundproofing, even expensive speakers will sound empty. Minimum set for Almera Classic:

  • 🔇 Vibroplast (pasted on the metal of the door).
  • 🔇 Splen (to absorb sound).
  • 🔇 Bitoplast (to seal the speaker).

Work order:

1. Remove the door trim.

2. Clean the metal from dirt and rust.

3. Apply vibroplast to the inside of the door (especially around the speaker).

4. Cover the holes with splen.

5. Place the speaker on the bitoplast to seal.

This procedure will take 3–4 hours on both doors, but the result is worth it - the bass will become deeper and the sound cleaner.

Common mistakes when replacing speakers and how to avoid them

Many owners Nissan Almera Classic encounter problems after replacing the speakers themselves. Here are the most common mistakes and their solutions:

  1. 🔌 Wrong polarity - if you confuse “+” and “–”, the speakers will play in antiphase, the sound will become “blurred”. Solution: check the polarity with a tester or battery (the diffuser should move outward when connecting “+” to “+”).
  2. 🔊 Using impedance speakers 2 ohm — the standard wiring and radio are not designed for such a load. Solution: take speakers from 4 ohm or install an amplifier.
  3. 🚪 Poor speaker seal - if there are gaps between the speaker and the door, the sound will be “dull.” Solution: use sealing rubber or bitoplast.
  4. 🔧 Ignoring soundproofing — without it, even expensive speakers will sound like “tin cans.” Solution: at least minimal treatment with vibroplast.
  5. 🎵 Lack of equalizer settings — many people install speakers and don’t adjust the sound. Solution: Spend 10 minutes adjusting the balance and frequencies.

Another common problem is noise when the speakers are working (crackling, whistling). This may be caused by:

  • 🔋 Poor contact in connectors (check all connections).
  • 🔌 Overload the radio (install a capacitor or amplifier).
  • 📻 Interference from the generator (try installing an interference filter).

Additional upgrades: amplifier, subwoofer and processor

If you want to receive really high quality soundRather than simply replacing burned out speakers, consider installing:

1. Amplifier

For Almera Classic A 4-channel power amplifier is suitable 50–70 W RMS to the channel. Popular models:

  • 🔊 Pioneer GM-D8604 - reliable and inexpensive.
  • 🔊 Alpine KTA-450 - compact, can be hidden under the seat.
  • 🔊 Focal FPA 4.320 - for audiophiles.

It is better to install the amplifier in the trunk or under the front seat. Don't forget about power wire (section not less 4 mm²) and fuse (calculated by the formula: amplifier power / 13.8 V).

2. Subwoofer

For deep bass Almera Classic A compact subwoofer in a housing is suitable:

  • 🎵 JBL GT-BassPro12 - active subwoofer, does not require a separate amplifier.
  • 🎵 Pioneer TS-WX120A - flat, can be installed in the trunk without losing space.

For the subwoofer you will need to lay a separate power cable and a signal wire from the radio (usually used RCA).

3. Sound processor

If you are using a stock radio but want to improve the sound, install DSP processor (For example, Dayton Audio DSP-408). It will allow:

  • 🎛️ Set the equalizer for each speaker separately.
  • 🎛️ Set audio delays to create the right scene.
  • 🎛️ Filter out interference from the generator.

The processor is installed between the radio and the amplifier. Setup takes time, but the results exceed expectations.

💡

If you're on a budget, start by replacing the front speakers and soundproofing the doors. An amplifier and subwoofer make sense only if you have high-quality speakers and want to listen to music at high volumes.

FAQ: Frequently asked questions about speakers in Nissan Almera Classic

Is it possible to install 16.5 cm speakers instead of the standard 13 cm ones on the rear shelf?

Technically possible, but it will be required serious revision:

  • Enlarge the hole in the metal of the shelf (you need a hacksaw or grinder).
  • Strengthen the mounting location, as vibrations from large speakers can damage the plastic.
  • Check whether the speaker is in the way of the trunk (in some cases you will have to sacrifice useful space).

We recommend staying at the standard size. 13 cm or consider installation 16.5 cm coaxial speakers in the front doors And tweeters in racks.

How to check if the stock speakers are working if there is no sound?

Follow this algorithm:

  1. Check the balance setting on the radio (the sound may have gone to the rear speakers, which are turned off).
  2. Disconnect the speaker connector and connect it directly to 9 volt battery. If the diffuser moves, the speaker is working.
  3. Check the wires from the radio to the speaker for a break (with a multimeter in 200 Ohm).
  4. Check the audio system fuse (in the fuse box under the steering wheel, usually 10–15 A).

If the speaker does not respond to the battery, it is burnt out and needs to be replaced.

Do I need to change wires when installing powerful speakers?

Yes, if:

  • You install speakers with power more than 60 W RMS.
  • Are you planning to connect an amplifier?
  • You hear distortion in the sound at high volumes (this is a sign that the standard wiring is not coping).

To replace use copper cable with a cross section of 1.5–2.5 mm². Do not skimp on wires - poor contact can lead to fire!

Which amplifier is better to choose for Almera Classic: 2-channel or 4-channel?

Depends on your system:

  • 2 channel suitable if you only want to connect front speakers + subwoofer (in bridge mode).
  • 4 channel needed for a complete system: front and rear speakers + the ability to connect a subwoofer (if the amplifier supports bridge mode).

For Almera Classic optimal 4 channel amplifier, as it allows you to flexibly customize the sound stage. Example: Alpine MRV-F300 or JBL Club A600.

Is it possible to install a radio with Apple CarPlay/Android Auto without losing sound quality?

Yes, but there are nuances:

  • 📱 Standard wiring in Almera Classic not always compatible with modern radios. Will be required ISO adapter.
  • 🔊 Sound quality depends on the built-in DAC of the radio. Budget models (up to 10 000 ₽) often have mediocre sound.
  • 🎛️ Settings: After installation, be sure to calibrate the equalizer for your new speakers.

Recommended models:

  • Pioneer SPH-DA130DAB — with Apple CarPlay and good sound.
  • Sony XAV-AX1000 - with touch screen and support Android Auto.
