Four channel amplifier in Nissan Kicks is not just a sound upgrade, but a full-fledged revolution in the sound system of your car. The standard audio system, even in top trim levels, often leaves much to be desired: weak bass, distorted highs and lack of dynamics at high volumes. Installation 4 channel amplifier solves these problems by allowing you to connect up to four speakers or a combination of front speakers and a subwoofer in bridged mode.

But how not to make a mistake when choosing among dozens of models from Pioneer, Alpine, JBL and other brands? What connection nuances are specific to Kicks with its factory radio or multimedia system NissanConnect? And why can even an expensive amplifier sound worse than a cheap one if the crossovers or signal levels are not adjusted correctly? In this guide, we will go through all the stages - from selecting equipment to fine-tuning the sound so that your Kicks started playing for real.

Why a 4-channel amplifier for Kicks?

Owners Nissan Kicks Often faced with a dilemma: install a monoblock for a subwoofer or choose a multi-channel amplifier. The four-channel model offers unique combination of flexibility and power — it allows:

  • 🔊Connect front and rear speakers separately, achieving balanced sound throughout the cabin.
  • 🎛️ Use bridge mode for powering the subwoofer (2 channels for the sub, 2 for the front speakers).
  • 📀 Save factory radio by connecting via LINE-OUT converter or high-level inputs.
  • 💰 Save space and budget compared to buying a separate amplifier for the subwoofer and front speakers.

Key benefit for Kicks — compact dimensions of the amplifier. Every inch counts in this crossover, especially if you don't want to sacrifice trunk space. Modern 4-channel models (for example, Alpine KTA-450 or Pioneer GM-D8704) are no larger than a book and easily fit under the seat or in a niche behind the trim.

But there are also pitfalls. For example, if your Kicks equipped with a system Bose (available in some markets), factory speakers may have non-standard impedance (2 ohms instead of 4 ohms), which will require a special amplifier that can support low-impedance loads. It is also worth considering that in basic configurations, speaker wires are often thinner than standard ones, and they will have to be replaced with thicker ones (with a cross-section of at least 1.5 mm²).

Top 5 4-Channel Amplifier Models for Kicks: Comparison of Features

The choice of amplifier depends on your goals: whether you just want to improve the factory sound or build a full-fledged audio system with a subwoofer. We have selected 5 models that are optimal for Nissan Kicks in terms of price/quality ratio and compatibility with its speaker system.

Model Power (RMS), W Class Features Price, ₽
Alpine KTA-450 45×4 D Compact, high efficiency, support 2 ohm 18 000
Pioneer GM-D8704 100×4 D Bridge mode 200 W × 2, built-in crossover 22 000
JBL Club A600 60×4 AB Low noise level, overheat protection 15 000
Hertz HCP 4D 85×4 D Support high-level input, compact body 28 000
Soundstream PCA4.640 60×4 AB Budget option, easy setup 12 000

For most owners Kicks the optimal choice would be Pioneer GM-D8704 - it offers enough power to replace factory speakers with component speakers (e.g. Focal ISU 165) and can simultaneously power a subwoofer in bridge mode. If you need maximum compactness, pay attention to Alpine KTA-450 — it can even be installed under the front seat.

⚠️ Attention: Class Amplifiers D (For example, Pioneer GM-D8704) are more efficient and compact, but may cause radio interference if mounted too close to the antenna. B Kicks The antenna runs along the rear window, so it is better to place the amplifier in the front part of the cabin.

Connection diagrams: how to integrate an amplifier with a factory radio

B Nissan Kicks There are three main ways to connect a 4-channel amplifier, each with its own pros and cons. The choice depends on whether you want to keep the factory radio or have already installed an aftermarket head unit (for example, Pioneer AVH-X5800).

1. Connection via LINE-OUT converter (LOC)

If you have a standard radio without RCA outputs, you will need LOC (Line-Out Converter). It converts the high level signal from the speakers into a low level signal for the amplifier. For Kicks suitable models:

  • 🔌 AudioControl LC2i — with signal level correction.
  • 🔌 Pac AOEM-GM24 - specialized for Nissan/GM.
  • 🔌 JL Audio CL-RLC - a premium option with minimal loss of quality.

The connection is made like this:

  1. We remove the factory radio (keys for dismantling - Nissan 7-8).
  2. We connect the LOC wires to the rear speakers (usually gray/gray-black and green/green-black wires in the radio connector).
  3. We connect RCA cables from the LOC to the amplifier located in the trunk or under the seat.
  4. Positive wire (+12V) we take it from the battery through the fuse, the negative one is placed on the body next to the amplifier.

2. Connection via high-level amplifier inputs

Many modern amplifiers (for example, Hertz HCP 4D) have high-level inputs, which allows you to do without LOC. In this case:

  • The wires from the speakers are connected directly to the amplifier.
  • The amplifier itself converts the signal and supplies it to the outputs.
  • Minus - possible loss of quality at high frequencies.

3. Connection to aftermarket radio

If you have already installed a radio with RCA outputs (for example, Sony XAV-AX5000), the scheme is simplified:

  • RCA cables go directly from the radio to the amplifier.
  • Control wire (REM) connects to the blue wire of the radio (ANT/AMP).
  • Power is taken from the battery through the fuse 50-60A.

Speaker polarity (phasing)|Section of power wires (at least 4 mm²)|Presence of a fuse on the battery|Quality of grounding (clean metal surface)-->

B Kicks 2020+ model years have one feature: the standard radio can “fall asleep” 10-15 minutes after the ignition is turned off, which will lead to the amplifier turning off. To avoid this, the control wire (REM) need to be connected to ACC+ (orange wire in the radio connector), and not to IGN.

Common installation mistakes and how to avoid them

Even experienced installers sometimes make mistakes that then have to be corrected. Here are the most critical moments for Nissan Kicks:

⚠️ Attention: In Kicks with the system NissanConnect (from 2021) if the LOC is connected incorrectly, the radio protection may be triggered, blocking the sound. To avoid this, use LOC with the function Auto Turn-On (For example, AudioControl LC2i Pro).
  • ⚡ Poor grounding: The amplifier will be unstable or produce humming noise. B Kicks The best grounding points are the front seat mounting bolts or the metal stand behind the glove compartment. Never ground yourself on plastic panels!
  • 🔥 Incorrect fuse: If you use a 30A fuse for an amplifier that draws 50A, the wiring may overheat. B Kicks The standard wiring to the fuse box can withstand up to 60A, but it is better to run a separate cable from the battery.
  • 🎵 Failure to comply with phasing: If the speakers are connected out of phase, the bass will disappear. You can check the phasing using a test track (for example, 50 Hz sine wave) - bass should be heard from the front, not the back.
  • 📶 Interference from the CAN bus: B Kicks The CAN wires run next to the audio wiring. To avoid noise, use shielded RCA cables and place them as far away from the stock wiring as possible.

Another typical problem is insufficient battery power. If you have installed a powerful amplifier (for example, Pioneer GM-D8704 at 100 W x 4) and listen to music at high volume with the engine turned off, the battery may be discharged in 20-30 minutes. Solution:

  • Install the capacitor 1 Farad next to the amplifier.
  • Or replace the standard battery with a model with a larger capacity (for example, Bosch S5 005 at 74 Ah).
What to do if the amplifier goes into protection?

If the amplifier turns off after a few minutes of operation, check:

1. **Supply voltage** - must be at least 12.5V (with the engine running - 13.8-14.4V).

2. **Load Impedance** - If you connect 2 ohm speakers to an amplifier that does not support low impedance loads, it will overheat.

3. **Ventilation** - in Kicks The amplifier under the seat may overheat. Add a cooler or move it to the trunk.

4. **The quality of RCA cables** - if they are damaged, the amplifier may perceive this as a short circuit.

Amplifier Tuning: A Step-by-Step Guide for Perfect Sound

Even the most expensive amplifier will sound bad if it is not tuned. B Nissan Kicks there are some nuances due to the acoustics of the cabin (small volume, a lot of plastic). Follow this algorithm:

1. Setting sensitivity (Gain)

This is the most important parameter. If you unscrew Gain to maximum, the amplifier will distort the sound. Best setting method:

  1. Set the volume on the radio to 75% of maximum (for example, 20 out of 30).
  2. Play a test track (eg 1 kHz sine wave).
  3. Increase smoothly Gain amplifier until distortion appears.
  4. Unscrew it back by 10-15% - this is the optimal level.

2. Setting up crossovers

There are usually two types of crossovers in a 4-channel amplifier:

  • 🔽 HPF (High-Pass Filter) — for front/rear speakers (cuts off bass below 80-100 Hz).
  • 🔼 LPF (Low-Pass Filter) — for a subwoofer (cuts off frequencies higher 80-120 Hz).

For Kicks recommended settings:

  • Front speakers: HPF 80 Hz, 12 dB/oct.
  • Rear speakers: HPF 120 Hz, 12 dB/oct (so as not to “conflict” with the front ones).
  • Subwoofer (if connected in bridged mode): LPF 80 Hz, 24 dB/oct.

3. Balance and fading

Inside Kicks the sound should be focused on the front passengers. Set up on the radio:

  • Fading (Front/Rear): +2 dB front.
  • Balance (Left/Right): 0 dB (if you are driving, you can add +1 dB left channel).
💡

For fine tuning, use a microphone and a spectrum analyzer application (for example, AudioTool on Android). Measure the sound level at the driver's seat and adjust Gain and crossovers to keep the schedule as smooth as possible.

Acoustics update: which speakers are suitable for a 4-channel amplifier

Installing an amplifier is only half the battle. Factory speakers in Kicks (usually Nissan 69200 or Clarion) are not designed for the power of an external amplifier and will distort the sound. Recommended replacement options:

Position Size Recommended Models Power (RMS)
Front (top) 10 cm (4") Focal IS 100, Morel Maximo 4 50-60 W
Front (bottom) 16.5 cm (6.5") JBL GTO609C, Alpine S-S65C 80-100 W
Rear 16.5 cm (6.5") Pioneer TS-A6990F, Kicker 43DSC69304 60-80 W
Subwoofer (bridged mode) 20-25 cm (8-10") JL Audio 10W0v3-4, Alpine S-W8D4 150-200 W

For front speakers it is better to choose component acoustics (with separate tweeters), since in Kicks Factory tweeters are often installed in the wrong places (for example, in the dashboard, not in the doors). When installing new speakers, remember to:

  • 🔧 Reinforce the doors with a vibration absorber (for example, StP Vibro).
  • 🔊 Use spacers for 16.5 cm speakers (in Kicks planting depth is limited).
  • 🎛️ Connect tweeters via capacitors (if they are not included in the package).

If you plan to install a subwoofer in bridged mode, pay attention to its impedance. For example, if you have an amplifier Pioneer GM-D8704 (stable at 4 ohms in bridged mode), then the subwoofer should be dual coil 4 Ohm × 2, connected in parallel (total resistance - 2 Ohms).

How much does installation cost and can I do it myself?

The cost of installing a 4-channel amplifier in Nissan Kicks depends on the scope of work:

Type of work Cost (₽) Time
Amplifier installation (without replacing speakers) 8 000 — 12 000 3-4 hours
Installing an amplifier + replacing front speakers 15 000 — 20 000 5-6 hours
Full upgrade (amplifier + component speakers + subwoofer) 25 000 — 35 000 8-10 hours
Sound and vibration insulation of doors 5 000 — 8 000 2-3 hours

Can I install the amplifier myself? Yes, if you have:

  • 🔧 Tool set (screwdrivers, terminal crimp, tester).
  • 📖 Wiring diagram Nissan Kicks (can be found in the manual or on Nissan Club).
  • 🕒 Time and patience (first installation may take 6-8 hours).

The most difficult moments when installing yourself:

  1. Laying the power cable from the battery to the amplifier (you need to drill a hole in the engine shield and protect the wire with corrugation).
  2. Connection to the standard radio (in Kicks The connector is non-standard, an adapter may be required).
  3. Setting up crossovers (it’s difficult to achieve perfect sound without an oscilloscope or special software).
⚠️ Attention: When installing it yourself, never connect the positive wire of the amplifier to the cigarette lighter or other “convenient” points. B Kicks The cigarette lighter is powered through a fuse 15A, which can lead to a fire in the wiring under high load.
💡

If you are not confident in your abilities, it is better to entrust the installation to professionals. Connection errors can lead not only to poor sound, but also to amplifier failure or even wiring fire.

FAQ: Frequently asked questions about 4-channel amplifiers in Kicks

Is it possible to connect a 4-channel amplifier to a stock radio without LOC?

Yes, if the amplifier has high-level inputs (For example, Hertz HCP 4D or Alpine KTA-450). In this case, the wires from the speakers are connected directly to the amplifier. However, the sound quality will be better when using LOC as it adjusts the signal level and reduces interference.

Which subwoofer can be connected to a 4-channel amplifier in bridged mode?

It depends on the power of the amplifier. For example, for Pioneer GM-D8704 (200 W × 2 in bridge mode) suitable:

  • JL Audio 10W0v3-4 (150 W RMS, 4 ohms × 2)
  • Alpine S-W8D4 (200 W RMS, 4 ohms × 2)
  • Kicker 43VCW104 (150 W RMS, 4 ohms)

Important: The subwoofer must be designed for the power that the amplifier produces in bridged mode. For example, if the amplifier delivers 200 watts, but the subwoofer is rated for 100 watts, it will quickly fail.

Why did hum (noise) appear in the speakers after installing the amplifier?

This is a common problem that occurs for several reasons:

  1. Poor grounding — check that the negative wire of the amplifier is securely screwed to the clean metal of the body.
  2. Interference from the CAN bus — RCA cables run next to the standard wiring. Solution: Use shielded cables and route them as far away from other wires as possible.
  3. Poor LOC - some cheap converters add noise. Try it AudioControl LC2i.
  4. Weak signal from radio — increase the signal level to LOC or check the radio settings (turn off the equalizer).
Do I need to change the battery after installing the amplifier?

Depends on the power of the amplifier and your style of listening to music:

  • If the amplifier is up to 50 W × 4 (For example, JBL Club A600), standard battery (60 Ah) that's enough.
  • If the amplifier is more powerful 100 W × 4 (For example, Pioneer GM-D8704) and you often listen to music at high volume with the engine off, it is better to install the battery on 70-75 Ah (For example, Varta Blue Dynamic D59).
  • An alternative is to install a capacitor 1 Farad next to the amplifier.
Can I connect a 4-channel amplifier to the Bose system in Kicks?

Yes, but there are nuances:

  • Amplifier Bose in Kicks has non-standard wiring, so a regular LOC may not work. A specialized adapter is required, e.g. Pac AOEM-NIS2.
  • Speakers Bose have resistance 2 ohm, so the amplifier must support a low-impedance load (for example, Alpine KTA-450 or JL Audio JD400/4).
  • After connecting, you will need to turn off the standard amplifier Bose, otherwise it will conflict with the new amplifier.

If you are not confident in your abilities, it is better to contact a car service center that specializes in Nissan - system Bose in Kicks sensitive to incorrect connection.
