Car Nissan Almera generation G15, produced since 2013, often becomes the target of modifications by owners who want to improve the sound quality of the standard audio system. The standard speakers in this model are usually made of cheap materials and are not able to convey clear sound, especially at high volumes. Replacing acoustics is not just a matter of volume, but a fundamental change in the perception of music in the cabin.
The process of upgrading the sound requires a careful approach to choosing equipment that is compatible with the dimensions of the standard installation locations. Many owners mistakenly believe that it is enough to buy any 16-centimeter speakers and screw them in, but reality dictates its own rules regarding the depth of the suspension and the availability of adapters. In this article we will analyze in detail which speakers are suitable for Nissan Almera G15, how to avoid problems with door cards and what needs to be done for high-quality sound.
Standard dimensions of acoustic seats and design nuances
Before you go to the store, you need to clearly understand what dimensions of the speakers are provided by the manufacturer at various points in the interior of your car. In the front doors Nissan Almera G15 The standard seat is designed for speakers with a diameter of 165 mm (or 16 cm). However, here lies the first catch: the depth of the magnet suspension on standard car speakers often exceeds the available space behind the door trim.
If you install a deep magnet speaker without any additional preparation, it will rest against the metal door shelf or the window lift mechanism. As a result, either the door will not close, or the speaker will vibrate against the metal, creating unpleasant overtones. To solve this problem, it is often necessary to use spacer rings or special adapter frames, which allow you to move the acoustics closer to the casing while maintaining the required gap.
The situation in the rear doors is similar, but the dimensions may vary depending on the year of manufacture and configuration. In most cases, there are also speakers installed there 16 cm, however, in some early batches or specific configurations there may be places for 13 cm (130 mm). Rear parcel shelf in sedans Almera usually occupied by 16 cm speakers, but their sound quality often suffers due to the lack of acoustic design.
- Front doors: standard size 160 mm with a critical installation depth.
- Rear doors: most common 160 mm, but requires inspection before purchase.
- Rear shelf: speakers can be placed on 160 mm or coaxial systems.
β οΈ Attention! Before purchasing speakers, be sure to check the magnet depth on the model you choose. If the magnet protrudes more than 5-6 cm from the front panel, you will need to make deep spacer rings from plywood or plastic, otherwise there will be problems with closing the doors.
Choosing the type of acoustics: coaxial or component system?
Owners Nissan Almera G15 often face a choice between coaxial and component speakers. A coaxial system, where the high-frequency tweeter is built into the center of the woofer, is a simpler and more cost-effective solution. It is easily installed in standard places and does not require complex wiring to the windshield pillars. For most drivers who listen to music at medium volumes, this option will be quite sufficient.
Component acoustics consist of separate units: a separate bass-midrange speaker and a separate tweeter. This solution provides a significantly better sound field and instrument localization accuracy. However, installing such a system in Nissan Almera will require additional effort: you will have to make racks for tweeter wires, make podiums or insert into plastic. Without this, the tweeter will not be able to work effectively, since the sound will be shielded by the door cards.
If you plan to use only the front channels for listening to music, then a component system in the front doors is an ideal choice. In this case, the rear doors can be left with coaxials or completely muffled so as not to create sound interference.
- Coaxial speakers: easy to install, acceptable sound quality, low price.
- Component acoustics: high sound fidelity, complex installation, need for podiums.
- Power: Look for models with a wattage rating 30-50 W for standard radio.
- Budget price
- Sound quality
- Easy to install
- Availability of backlight
Necessary accessories for a quality installation
Even the most expensive and high-quality speakers will not sound right if they are installed incorrectly. In the case of Nissan Almera G15 The critical element is the transition frames (adapters). The standard place in the door has a specific shape, and modern speakers often have a round shape with different mounting holes. Without an adapter, it will not be possible to securely attach the speaker, which will lead to vibrations and loss of low frequencies.
In addition to frames, soundproofing of doors will definitely be required. Metal doors Almera thin and resonates at certain frequencies, creating a hum. Applying vibration-absorbing materials to the inside of the door and installing a dense layer of sound insulation on the door card will radically change the character of the sound. This will allow the speakers to operate in a closed volume, delivering more bass and clarity.
It is also worth paying attention to the wiring. Standard wires in Nissan often have an insufficient cross-section and can oxidize over time, especially under Russian road conditions and climate. If you are installing powerful speakers, it is recommended to lay a new power cable with a cross-section of at least 2.5 mmΒ² to avoid signal losses and power drops over long sections of the route.
βοΈ Preparing to install speakers
How to remove the door card on Almera G15?
To remove the card, you need to unscrew the screws in the door handle and under the cup holder. Then carefully pry off the plastic clips around the perimeter of the door, using a plastic spatula so as not to scratch the upholstery. Be careful with the lock cable, which must be carefully disconnected from the inside.
Features of installation in front doors
Installing speakers in the front doors Nissan Almera begins with dismantling the casing. This is necessary not only for access to the mounting location, but also for carrying out sound insulation work. After removing the door card, you will see a metal shelf with a hole for the speaker. Often this hole is covered with a plastic mesh, which is better replaced with a higher-quality perforated panel for better sound transmission.
The key point of installation is creating a sealed volume. If there are gaps between the speaker and the door, the bass will drop out and the sound will become flat. Use rubber band or caulk to seal the joint between the adapter and the metal of the door. The speaker should fit tightly, without any play. It is better to replace the mounting screws with longer and better ones to prevent them from unscrewing due to vibrations.
The wiring to the speaker must be done carefully so that it does not interfere with the operation of the window regulator. Use corrugated tubing to protect insulation from sharp metal edges. If you are installing component speakers, the wires to the tweeters should be routed through the technological holes in the windshield pillar, using flexible protective tubes to prevent chafing.
β οΈ Attention! When working on power windows, be sure to disconnect the battery terminal before starting work. Incorrect connection of wires or metal getting into the window regulator mechanism can lead to a short circuit and failure of the window control unit.
Rear acoustics and work with the rear shelf
In sedans Nissan Almera G15 The rear shelf is an excellent place to install acoustics, but it has its own design features. The shelf is made of plastic and can resonate at high volumes. To improve sound quality, it is recommended to strengthen the shelf by gluing a layer of vibration insulation to it or even a metal sheet, if the mounting design allows it.
If you decide to install speakers in the rear doors, keep in mind that space there is even more limited than in the front doors. Often you have to use speakers with a shortened magnet or special spacers. Many car owners prefer not to clutter the rear doors with speakers, leaving them empty to improve sound insulation of the interior, and installing speakers only in the front part and on the rear parcel shelf.
For the rear shelf, full-range speakers or coaxial systems with a soft diffuser suspension are best suited. This will ensure a balanced filling of the cabin with sound without harsh distortion. It is important to correctly adjust the sound balance between front and rear so as not to create the feeling that the music is playing from the trunk.
- Rear shelf: requires reinforcement to eliminate plastic vibrations.
- Rear doors: Space limited, low profile speakers required.
- Sound Balance: Adjustment
Faderin the radio should shift the emphasis to the front channels.
Before installing speakers on the rear parcel shelf, check that they will not block the view through the rear window. Some speaker models have tall tweeters, which can obscure visibility, especially if you don't have a rearview camera.
Comparison table of popular speaker models
To simplify the choice, we have prepared a comparison of several popular speaker models that have proven themselves to be excellent when installed in Nissan Almera G15. These models differ in price, diffuser material and sensitivity, which affects their compatibility with the standard radio.
| Speaker model | Diameter | Sensitivity (dB) | Diffuser material | Recommendation |
|---|---|---|---|---|
| Alpine SXE-1750S | 165 mm | 91 | Paper/Polypropylene | Excellent for a stock radio |
| Pioneer TS-G1731S | 165 mm | 90 | Polypropylene | Good balance of price and quality |
| Supra SFS-6.5 | 165 mm | 89 | paper | Budget option with acceptable sound |
| Hertz Dieci DSK 165.3 | 165 mm | 93 | Cellulose | Maximum volume without amplifier |
When choosing, pay attention to sensitivity. The higher this number (measured in dB), the louder the speaker will play at the same power. For Nissan Almera with a standard radio, it is better to choose models with a higher sensitivity 90 dB, since the standard amplifier does not produce much power.
High sensitivity of the speakers is critical for working with a standard radio, as it allows you to get loud and clear sound without the need to install an additional power amplifier.
Connecting and setting up the audio system
After physically installing the speakers, the connection phase begins. B Nissan Almera G15 Speaker connectors are often color coded or shaped differently. It is recommended to use universal adapters with wires that can easily be connected to the standard radio connector and to the speaker terminals. This will avoid soldering and maintain the ability to quickly dismantle the equipment.
It is important to observe the polarity of the connection. If you mix up "+" and "-", the phase of the speaker will change, and the sound will become flat and the bass will disappear. Use a tester or battery to check polarity: when connected briefly, the diffuser should move outward, not inward. If it moves inward, swap the wires.
The sound settings are made through the menu of the standard radio. Set the Balance and Fader to the center or slightly toward the front speakers. Turn off any equalizer settings like "Bass Boost" or "3D Sound" as these often introduce distortion. Leave the settings flat for the most natural sound.
β οΈ Attention! Never turn on the radio at maximum volume immediately after installing new speakers. Let them βget used toβ (play music at medium volume for 10-15 hours) so that the suspension stabilizes and the speakers reach operating mode.
Common mistakes and how to avoid them
One of the most common mistakes is ignoring the issue of tightness. Many owners simply screw the speaker to the frame without closing the gap between the frame and the metal of the door. This causes the low frequencies to "go away" into emptiness and the bass becomes unclear. Always use seals or sealant during installation.
Another mistake is using low-quality wires. Thin or oxidized wires create high resistance, resulting in loss of power and distorted sound. Use copper wires with a cross-section of at least 1.5-2.5 mmΒ² and high-quality terminals. Avoid twists and tape; it is better to use heat-shrinkable tubing and crimp sleeves.
You should also avoid installing too powerful speakers without an amplifier. Speakers with a nominal power of 100-150 W and a sensitivity of 88 dB on a standard radio will play quietly and distorted at high volumes, since the radio will not be able to drive them. It is better to choose less powerful but more sensitive models.
Why do doors buzz at high volumes?
Ringing noise in doors is usually caused by metal resonance or poor speaker fixation. It can be eliminated by applying vibration insulation to the outer and inner door flanges, as well as using high-quality spacer rings and sealing the joints.
FAQ: Answers to popular questions
Is it possible to install 16 cm speakers in the front doors of Almera G15 without spacers?
Without spacer rings this is extremely difficult and risky to do. The depth of the standard place is small, and most high-quality speakers will rest against the window lift mechanism or a metal shelf. Spacers are necessary to move the speaker closer to the casing.
How thick should vibration insulation be for doors?
For front doors, it is recommended to use two-layer vibration insulation. The first layer is a 2-3 mm thick vibration absorber on the outer shelf, the second layer is a sound absorber (felt or bitoplast) on the door card. This will significantly improve sound quality and reduce wind noise.
Do you need an amplifier to improve the sound in Nissan Almera?
An amplifier is necessary if you want to get powerful and deep bass, as well as high-quality sound at high volumes. For standard replacement of speakers with more sensitive models, an amplifier is not required, but is desirable for a full-fledged component system.
How to determine the polarity of speakers without instruments?
Connect the speaker to the 1.5V battery for a moment. If the diffuser moves out, it means that the β+β of the battery is connected to the β+β of the speaker. If it moves inward, the polarity is reversed. This is a simple and reliable verification method.
Can I use the stock wires to connect new speakers?
Standard wires in Nissan Almera often have insufficient cross-section and can oxidize. It is recommended to replace them with new copper wires with a cross-section of at least 1.5 mmΒ², especially if you plan to install more powerful speakers or an amplifier.
