Owners Nissan Almera Classic (especially models B10 1995–2000 and restyled G15 2006–2012) often encounter a problem: the standard audio system leaves much to be desired. The bass is hoarse, the high frequencies hurt the ears, and the sound stage is completely absent. The reason is trivial - factory speakers are designed for minimum cost, not quality. But before upgrading the acoustics, you need to know for sure speaker sizes, their location and connection nuances, otherwise you risk wasting money or damaging the electrics.

In this article - complete technical data on speakers for all modifications of Almera Classic, including rare configurations with a premium audio system Bose. We will analyze not only the dimensions, but also typical mistakes when replacing (for example, why new speakers may not fit even if the diameters are the same), and also provide a checklist for checking compatibility. If you're planning to improve the sound in your Almera, read on to avoid costly mistakes.

Standard speakers Nissan Almera Classic: location and dimensions

B Nissan Almera Classic the speakers are installed at four standard points, but their number and size depend on the year of manufacture and configuration. Basic versions (eg 1.4i or 1.6i with audio preparation) were equipped only with front speakers, and the top ones were equipped with a full-fledged 4-speaker system. Below is the exact data for all modifications.

Important: even within the same model, sizes may vary! For example, in Almera Classic G15 2008 front speakers have a diameter 16.5 cm, and in the restyled version of 2010 - already 17 cm. You can check the exact size using the VIN code or visually by removing the grille.

  • 🔊 Front speakers: 16.5 cm (6.5 inches) is standard on most versions. In premium trim levels (for example, TE or SE) 17-centimeter ones could be installed.
  • 🔊 Rear speakers: 13 cm (5.25 inches) - only on vehicles with factory audio system. The basic versions do not have rear speakers, but there are places for installation.
  • 🔊 Twitter: not included as standard. Places for installation - in the front door pillars or on the dashboard (requires modification).

Feature Almera Classic: The front speakers are mounted on three-point brackets, and not on standard round holes. This means that even if the diameter of the new speaker is the same, it may not be able to mount without adapter rings or reworking of the metal. More on this in the next section.

Table: exact speaker sizes by year and configuration

To avoid mistakes when purchasing, we collected data for all generations Almera Classic. Pay attention to the “Depth” column - this parameter is often overlooked, but it is critical for installation. For example, a speaker with a diameter of 16.5 cm can have a depth of 4.5 to 6.5 cm, and if this is not taken into account, the speaker will rest against the glass of the door.

Model/year Front speakers Rear speakers Depth (max) Fastening
Almera Classic B10 (1995–2000) 16.5 cm (6.5") 13 cm (5.25") or none 5.5 cm 3-point (metal)
Almera Classic G15 (2006–2008) 16.5 cm (6.5") 13 cm (5.25") 6.0 cm 3-point (plastic)
Almera Classic G15 (2009–2012, restyling) 17 cm (6.75") 13 cm (5.25") or 16.5 cm (in versions with Bose) 6.5 cm 4-point (plastic)
Almera Classic TE/SE (premium) 17 cm (6.75") 16.5 cm (6.5") 7.0 cm 4-point + additional fastenings

⚠️ Attention: In cars with factory system Bose (rare for the Russian market) rear speakers may have non-standard mounting. Before purchasing, remove the casing and measure the holes - otherwise you risk getting speakers that cannot be fixed.

How to Check Compatibility of New Speakers: 5 Critical Parameters

Choosing speakers by diameter is only half the battle. In order for them to install without modifications, you need to take into account at least 5 more nuances. Neglecting at least one of them can lead to the speakers not physically fitting or “wheezing” due to improper fastening.

  • 📏 Seat depth: in Almera Classic it varies from 4.5 to 7 cm. If the speaker is deeper, it will rest against the glass or window lift mechanism.
  • 🔧 Mounting type: 3-point (old models) or 4-point (restyling). Adapter rings solve the problem, but not always.
  • 🔌 Resistance (impedance): The standard radio is designed for 4 ohms. Speakers with an impedance of 2 ohms can overload the amplifier.
  • 🎛️ Sensitivity (dB): for Almera Classic optimally 90–92 dB. Less sensitive speakers will sound quiet without an amplifier.
  • 🔄 Connection polarity: in standard wiring, “plus” and “minus” are often confused. Check with a tester before installation!

🔹 Practical advice: If you plan to install larger speakers (for example, 17 cm instead of 16.5 cm), check in advance whether the window handle or door trim is in the way. In 30% of cases, plastic trimming is required.

Top 5 mistakes when replacing speakers in Almera Classic

Even experienced car owners make mistakes when upgrading acoustics. We have collected the most common mistakes that lead to poor sound or breakdowns. For example, many people forget about phasing - if you reverse the polarity on one of the speakers, the bass will “disappear” and the sound will become “flat”.

Another typical problem is ignoring acoustic design. At the door Almera Classic There is no factory sound insulation, and without it, new speakers will sound worse than old ones due to resonances. Minimum set: vibroplast for metal + splen for sheathing.

⚠️ Attention: Never connect speakers with an impedance of 2 ohms to the stock radio! This will lead to overheating of the amplifier and its failure. If you want low-impedance acoustics, be sure to install an external amplifier.
  • 🔇 Error 1: The polarity of the wires has not been checked. The consequence is a lack of bass and a “smeared” sound.
  • 🔧 Error 2: The speakers are fixed without adapter rings. The consequence is vibration and rattling at high frequencies.
  • 🔊 Error 3: Ignoring seat depth. The consequence is that the speaker rests against the glass, and the sound is distorted.
  • 🎵 Error 4: Lack of sound insulation. The consequence is resonances at mid frequencies, “booming” of the bass.
  • 🔌 Error 5: Connecting 2-ohm speakers to the standard radio. The consequence is a burnt out amplifier.

Before installing new speakers, disconnect the battery! B Almera Classic If there is a short circuit in the audio system, the fuse may blow F10 (10A), also responsible for the cigarette lighter.

The best speakers for Nissan Almera Classic: review of models

The choice of acoustics depends on your budget and goals. For basic sound enhancement, coaxial speakers are suitable with sensitivity 90+ dB and impedance 4 ohms. If you want high-quality sound, you will have to fork out for a component system with an external amplifier. Below are proven options for different tasks.

🔹 Budget option (up to RUB 5,000 per couple):

  • 🎵 Pioneer TS-A1670F (16.5 cm, 4 Ohm, 90 dB) - fits perfectly into standard places, good mids and highs.
  • 🎵 JBL GTO629 (16.5 cm, 3 Ohm, 92 dB) - a little more powerful, but require checking compatibility with the radio.

🔹 Middle segment (RUB 5,000–RUB 15,000 per couple):

  • 🎵 Focal Access 165CA1 (component system, 16.5 cm) - excellent high frequencies, but needs some work to install tweeters.
  • 🎵 Alpine SXE-1725S (17 cm, 4 Ohm) - suitable for restyled versions, deep bass.

🔹 Premium (from 15,000 ₽):

  • 🎵 Hertz DCX 165.3 (component, 16.5 cm) - top sound, but requires an amplifier and sound insulation.
  • 🎵 Morel Tempo Ultra 692 (17 cm) - for real music lovers, but the mounts need to be reworked.

⚠️ Attention: B Almera Classic with factory radio Clarion (installed in top-end configurations) problems may arise with connecting component systems. The solution is to replace the radio or install a processor.

How to check the original radio for compatibility?

Turn on the ignition and press simultaneously 1 And 6 on the radio panel. If the service menu appears with the software version (for example, CL01-1234), which means it's original Clarion, and component speakers will require an external crossover.

Step-by-step instructions for replacing speakers

Installing new speakers in Almera Classic does not require special skills, but there are nuances. For example, in the front doors you will have to remove the trim, disconnect the window regulator and carefully remove the standard column without damaging the wires. We will break the process into stages with photos and tips.

🔹 Tools: T20 screwdriver, flat screwdriver, pliers, polarity tester, soundproofing cutting knife.

  1. Removing the door trim:
    • Unscrew the two screws under the door handle (under the decorative cap).
    • Carefully pry the clips around the perimeter with a flat-head screwdriver. Start from the bottom corner!
    • Disconnect the power window and speaker connectors (do not pull the wires!).
  2. Removing the old speaker:
    • Unscrew the 3 (or 4) mounting bolts.
    • Disconnect the terminals, first marking the polarity with a marker.
    • Check the seat depth with a ruler.
  3. Installing a new speaker:
    • If necessary, install an adapter ring (available at auto stores).
    • Connect the terminals, observing polarity.
    • Secure the speaker with bolts without over-tightening (you may strip the threads!).
  4. Testing and assembly:
    • Connect the battery and test the sound at different frequencies.
    • If everything works, reassemble the casing in reverse order.

🔹 Important: B Almera Classic G15 When assembling the door trim, watch the position of the glass - if it is not fully raised, the clips may not fit into place.

💡

If, after installing new speakers, the sound becomes quieter than with the old ones, check the radio settings (the equalizer may be activated) or the polarity of the connection.

FAQ: answers to frequently asked questions

Is it possible to install 17 cm speakers instead of 16.5 cm?

Yes, but only in restyled versions G15 (2009–2012). In old B10 You will need to widen the hole and modify the casing. Also check the depth - 17cm speakers are often deeper than stock speakers.

Which amplifier is suitable for a component system?

For Almera Classic a 4-channel amplifier with a power of 50–75 W per channel is optimal (for example, Pioneer GM-D8604 or Alpine KTP-445U). If you are planning a subwoofer, take a 5-channel one (for example, JBL Club A5005).

What should I do if noise appears after replacing the speakers?

The reasons may be different:

  • Poor contact in the terminals (check the connection is secure).
  • The polarity is reversed (swap “+” and “–” on the same speaker).
  • Problems with ground (clean the contact on the body).
  • Impedance incompatibility (if the speakers are 2 ohms, and the radio is designed for 4 ohms).

Do I need to change the radio for good sound?

Not required, but recommended. Head unit Almera Classic has a weak amplifier (15–20 W per channel) and a primitive equalizer. If you are installing a component system or subwoofer, it is better to install a head unit with RCA outputs (for example, Pioneer DEH-S4200BT).

Where to buy adapter rings for speakers?

Adapter rings (adapters) for Nissan Almera Classic sold in auto stores (for example, AutoSound, CarAudio) or on AliExpress (search for “Nissan Almera speaker adapter”). The average price is 300–800 RUR per set.
