Nissan Almera G15 (2012–2018) - a popular sedan with factory acoustics, which often disappoints audiophiles. Dull sound, lack of bass and wheezing at high frequencies are typical complaints from owners. Replacing speakers with higher-quality components can transform the sound of the cabin, but requires knowledge of the nuances: from the choice of acoustics to the correct connection to the standard radio.

In this article you will find step-by-step instructions for replacing front and rear speakers, analysis of typical errors (for example, why new speakers are “silent” after installation), as well as recommendations for choosing acoustics taking into account electrical features Almera G15. We analyzed reviews from owners and the experience of auto electricians to collect the most practical advice - without fluff and general phrases.

What speakers are installed in the Nissan Almera G15 from the factory?

Factory sound system Almera G15 depends on the configuration, but in 90% of cases the standard configuration is used:

  • 🔊 Front speakers: 16 cm (6.5 inches), 2 way coaxial, impedance 4 ohm, power ~20 W. Installed in door cards.
  • 🔊 Rear speakers: 13 cm (5.25 inches), 2 way coaxial, impedance 4 ohm, power ~15 W. Located on the rear window shelf.
  • 🎵 Twitter: not available in basic versions. In top trim levels (for example, Tekna) can be built into the A-pillars.

The main problem of factory acoustics is weak magnets and paper diffusers, which quickly degrade from moisture and temperature changes. In addition, the standard radio (Clarion or Panasonic) does not produce enough power for normal sound even from new speakers. This means that it may take replacing the head unit or installing an amplifier.

Important: in Almera G15 2016–2018 release with system NissanConnect speakers with non-standard connectors are used - replacing them will require an adapter or cutting the wires.

How to choose replacement speakers: sizes, power, brands

When choosing a new speaker, consider three key parameters:

  1. Size: front - 16 cm (6.5"), rear - 13 cm (5.25"). Installation of 16-centimeter speakers in the rear is allowed, but modification of the seat will be required.
  2. Resistance: 4 ohm (the standard radio does not support 2 ohm).
  3. Sensitivity: not lower 90 dB — this compensates for the weak signal from the standard head unit.

Recommended brands (price/quality ratio):

Brand Model (front) Model (rear) Features
Pioneer TS-A1670F TS-A1370F Good bass, moisture resistant
JBL GTO629 GTO529 High sensitivity (93 dB)
Alpine SXE-1725S SXE-1325S Lightweight magnet, suitable for weak radios
Morel Tempo Ultra 6 Tempo Ultra 5 Premium sound, but requires an amplifier

⚠️ Attention: If you plan to install speakers with a power greater than 50W RMS, be sure to add it to the system capacitor (1 farad) or amplifier. Standard wiring Almera G15 not designed for high loads - this can lead to overheating of fuse F30 (10A) in the fuse box under the hood.

Tools and materials for replacing speakers

To work you will need:

Torx T20 screwdriver (for fastening door panels)

Plastic spatulas for removing clips

Soldering iron or crimp terminals (for connecting wires)

Multimeter (to check polarity)

Electrical tape/heat shrink

New speakers with adapters (if needed)

Silicone sealant (for waterproofing)

-->

⚠️ Attention: Do not use metal screwdrivers to remove plastic door panel clips! B Almera G15 The clips are fragile and break easily. If one of them is broken, replace it with a new one (part number: 77010-4M000).

Also prepare your workplace:

  • 🚗 Place the machine on a flat surface and disconnect the battery (remove the negative terminal).
  • 🔌 If the radio is encrypted, make sure you have PIN code to unlock.
  • 📱 Take a photo of the location of the wires before disconnecting the speakers - this will help to avoid mistakes during reassembly.
💡

Before starting work, turn on the music at medium volume and turn off the speakers one by one (front left, front right, etc.) to understand which one is producing wheezing or distortion. This will help diagnose the problem more accurately.

Step-by-step instructions: replacing the front speakers

Front speakers in Almera G15 hidden behind the door cards. Replacing them requires care, since the power window wires and the mirror control unit pass through the doors.

1. Removing the door panel

Algorithm of actions:

  1. Remove the plastic plug from the door handle (pry it off with a spatula).
  2. Unscrew two screws Torx T20 under the plug.
  3. Remove the power window control button (carefully pry it from the side).
  4. Remove the screw under the speaker trim (if equipped).
  5. Use a spatula to pry off the clips around the perimeter of the panel, starting from the bottom corner.

⚠️ Attention: At the door Almera G15 There is a hidden screw under the decorative speaker trim (in some trim levels). If the panel cannot be removed, check its presence!

2. Removing the old speaker

After removing the panel, you will see the speaker secured to a metal bracket with four self-tapping screws. Disconnect the power connector (it may be secured with a plastic clip). If the connector is non-standard (for example, in machines with NissanConnect), use an adapter or cut the wires, leaving a margin for soldering.

Tip: If the speaker is sealed to the door, carefully trim it with a knife to avoid damaging the plastic housing of the new speaker.

3. Installing a new speaker

Before installation:

  • 🔧 Check the polarity of the wires with a multimeter (plus is usually marked in red or white).
  • 🎯 If necessary, use spacer rings (if the new speaker is deeper than the factory one).
  • 🌧️ Apply a thin layer of silicone sealant around the edge of the speaker to protect it from moisture.

Secure the speaker with self-tapping screws (do not overtighten so as not to deform the housing) and connect the wires. To ensure a reliable connection, use soldering or crimp terminals - the “twists” oxidize over time.

What to do if the new speaker does not sound?

If the speaker is silent after installation, check:

1. Connection polarity (swap wires).

2. Integrity of fuse F30 (10A) in the block under the hood.

3. Radio settings: the corresponding channel may be disabled (in the menu Audio → Balance/Fader).

4. Quality of contact in the connector - sometimes cleaning oxidized wires helps.

Replacing rear speakers: nuances and mistakes

Rear speakers in Almera G15 located on the rear window shelf. Replacing them is easier than the front ones, but has its own characteristics:

  1. Access: To get to the speakers, you need to remove the shelf trim. It is attached with clips and two self-tapping screws under plastic plugs.
  2. Wiring: The rear speaker wires run through the corrugation along the rear pillar. Be careful - they can be easily damaged when removing the trim.
  3. Sealing: After installing new speakers, be sure to seal the joints with tape or sealant to avoid squeaks.

⚠️ Attention: In some versions Almera G15 rear speakers connected via decoupling capacitor (located under the shelf trim). If you are installing component speakers, it must be removed - otherwise the high frequencies will be cut off.

Tip: If you are replacing the rear speakers with more powerful ones (e.g. JBL GTO629), make sure the rear window shelf can withstand vibration. Strengthen it if necessary vibration absorber (For example, StP Vibro).

Connection and configuration: how to avoid mistakes

After replacing speakers, it is important to set them up correctly. Let's start with the connection:

  • 🔌 Polarity: All speakers must be connected in phase. You can check this by connecting the battery and turning on music - if the sound is “smeared”, change the wires on one of the speakers.
  • 🎛️ Radio settings: Reset the equalizer to factory settings (Flat), then gradually adjust the bass and treble.
  • 🔊 Sound test: Listen to tracks with a wide frequency range (such as "Boom Boom Pow" from Black Eyed Peas for bass or "Hotel California" for high frequencies).

Typical errors after replacement:

Problem Reason Solution
Speakers wheeze at high volumes Weak radio power Install an amplifier or capacitor
Sound is dull, no bass Leaky speaker mount Check seal, add vibration absorber
One speaker is quieter Broken wire or incorrect polarity Test the circuit with a multimeter

💡

If after replacing the speakers the sound becomes worse than it was, in 90% of cases the problem lies in wrong polarity or bad contact at the connection points of the wires. Always check the circuit with a multimeter!

Additional improvements: amplifier, noise isolation, tweeters

Replacing speakers is only the first step to good sound. Consider the following improvements:

  • 🔊 Amplifier: even a budget 4-channel amplifier (for example, Pioneer GM-A3702) will significantly improve the sound. Installs in the trunk or under the front seat.
  • 🔇 Noise insulation: door treatment StP A2 or Bitumast will reduce vibrations and improve bass. Pay special attention to the inside of the door card.
  • 🎵 Twitter: If they don't come from the factory, install them in the A-pillars (eg. Focal TW 25). To do this you will need to run wires from the radio.
  • 🔋 Capacitor: if the light in the cabin dims with bass, install a capacitor with a capacitance 1 Farad next to the battery.

⚠️ Attention: When installing the amplifier, do not connect it directly to the battery through the fuse on 100A - this may lead to a fire in the wiring. Use power wire with a cross-section of at least 4 mm² with fuse 60A, installed 30 cm from the battery.

Tip: if you are installing component speakers (separate midbass and tweeters), use crossovers, included in the kit. They will help to correctly distribute frequencies between the speakers.

FAQ: answers to frequently asked questions

Is it possible to install 6x9 speakers instead of the rear 5.25" ones?

Theoretically yes, but it will be necessary significant modification of the seat: widening the hole and strengthening the shelf. Ready-made transition frames for Almera G15 does not exist, so the work will have to be done “by eye”. An alternative is to install 16cm speakers with adapters.

Why do new speakers whistle at high frequencies?

This is a sign overload or incorrect installation. Possible reasons:

  • The speaker power is too high for the standard radio.
  • Lack of sealing (air passes through the cracks, causing a whistle).
  • The polarity is connected incorrectly (the phase is out of phase).

Solution: Check your equalizer settings, reduce the treble, and make sure the speaker is screwed in tightly.

Do I need to change wires when replacing speakers?

Factory wires in Almera G15 thin (section ~0.5 mm²), but for speakers with power up to 50 W there are enough of them. If you install more powerful acoustics, replace the wires on copper with cross-section 1.5–2 mm². Pay special attention ground wire — it must be securely fastened to the body.

How to reset the radio settings after replacing the speakers?

If the sound disappears or distortion appears, perform a reset:

  1. Press and hold the button Power (or Src) for 10 seconds.
  2. Enter the PIN code (if the radio is locked).
  3. Go to Settings → Sound → Reset.

If the radio NissanConnect, reset is done through the menu System → Recovery.

How much does it cost to replace speakers at a service center?

The cost of work in a car service depends on the region and complexity:

  • Replacing front speakers: 1,500–2,500 rub. for a couple.
  • Replacing rear speakers: 1,000–1,800 rub. for a couple.
  • Twitter installation: 2,000–3,500 rub. (including wiring).

Replacing it yourself will cost only the cost of the speakers (from 3,000 rub. for a budget kit).
