Technical characteristics of the KICKS 4.160 amplifier

Model KICKS 4.160 belongs to the class AB amplifiers, which provides a compromise between energy efficiency (like Class D) and sound quality (like Class A). Main parameters:

  • 🔊 Number of channels: 4 (possibly bridging for subwoofer)
  • ⚡ Power(RMS): 4 × 160 W at 4 ohms, 4 × 220 W at 2 ohms
  • 📊 Frequency range: 10 Hz – 40 kHz (±1 dB)
  • 🔄 Crossovers: built-in high and low pass filters (50–500 Hz)
  • 🔌 Inputs: RCA (low-level), high-level (speaker-level) for connection to the standard radio
  • 🛡️ Protection: from overheating, short circuit, overvoltage

Feature of the model - compact body (dimensions 230x160x50 mm), which allows it to be installed even in limited space, for example, under a seat or in the trunk Nissan Kicks. In this case, the amplifier is equipped ventilation grilles for passive cooling, which reduces the risk of overheating during prolonged use at high volume.

Important: the KICKS 4.160 amplifier does not support operation with a load of less than 2 Ohms in bridge mode - this can lead to failure of the output stage.

Comparison with analogues: which is better?

In the car amplifier market KICKS 4.160 competes with models from Pioneer, Alpine And JBL. Let's compare the key parameters:

  • 💰 Price: KICKS 4.160 cheaper Alpine MRV-F300 by 20–30%, but is inferior in power to a high-resistance load.
  • 🔧 Functionality: Unlike Pioneer GM-D8604, has built-in crossovers, but no bass boost.
  • 🔌 Connection: Supports high level inputs (like JBL Club A600), which simplifies integration with the standard radio.

Main advantage KICKS 4.160 — price/quality ratio. It is ideal for systems where extreme power is not required, but clear sound and reliability are important. For example, for Nissan Kicks 2020+, where the stock audio system is weak in the midrange, this amplifier will be an excellent upgrade without replacing the head unit.

⚠️ Attention: when choosing between KICKS 4.160 And Pioneer GM-D8604 Keep in mind that the latter requires a separate processor to configure crossovers, which increases the final cost of the system.

Connection diagrams: step-by-step instructions

Amplifier installation KICKS 4.160 includes several stages: choosing a mounting location, laying cables, setting up inputs/outputs and connecting to a power source. Let's look at each step in detail.

1. Selecting an installation location

Optimal options for Nissan Kicks:

  • 🚗 Under the front seat: saves space but requires short interconnect cables.
  • 📦 In the trunk: easy to access, but needs protection from moisture.
  • 🔧 Behind the rear shelf: hidden installation, but difficult to maintain.

2. Cable routing

Use oxygen free copper cable cross-section of at least 4 mm² for power supply and 1.5 mm² for acoustics. Laying route:

  1. From battery to amplifier (via 60–80 A fuse).
  2. From the radio to the amplifier (RCA cables or high-level wires).
  3. From amplifier to speakers (observe polarity!).

Check battery voltage (should be ≥12.6 V)

Install the fuse near the battery (maximum 30 cm from the terminal)

Isolate signal cables from power cables (distance ≥10 cm)

Check the speaker impedance (at least 2 ohms per channel) -->

3. Amplifier settings

Once connected, perform basic setup:

  1. Install Gain to a minimum.
  2. Set up crossovers: for front speakers - HPF 80 Hz, for the rear - HPF 120 Hz.
  3. Increase smoothly Gain, avoiding distortion (use 1 kHz test signal).
⚠️ Attention: if after tuning you hear wheezing at high volume, check the grounding of the amplifier. The optimal place for the “ground” is a bolt on the body near the installation site, stripped to bare metal.

Common installation mistakes and how to avoid them

Even experienced installers sometimes make mistakes that ruin the sound or shorten the life of the amplifier. Here are the most common:

  • ❌ Incorrect grounding: Using stock bolts with paint or rust will cause interference. Solution: clean the contact area and use a star washer.
  • ❌ RCA cables that are too long: The signal loses quality at a distance of more than 3 meters. Solution: lay cables along the shortest path or use shielded models.
  • ❌ Ignoring polarity: Incorrect connection of speakers leads to mutual cancellation of bass. Solution: check the phasing with a test signal.

Another common problem is on-board network overload. Amplifier KICKS 4.160 consumes up to 30 A, therefore:

  • 🔋 Install additional capacitor (1 Farad) near the amplifier if voltage sags are observed.
  • ⚡ Replace the standard generator with a more powerful one (for example, 120 A) if the system has a subwoofer.
What happens if you confuse “+” and “-” when connecting power?

The amplifier will not turn on, but the worst case scenario is failure of the diode bridge. In 90% of cases, it is enough to change the polarity, but if there is a burning smell, repair is required.

Sound settings: secrets of professionals

To unlock your potential KICKS 4.160, it is not enough to simply connect it to the speakers. Here 3 key parametersthat need to be configured:

  1. Gain level: should be such that at maximum volume of the radio the amplifier does not go into clipping. Use an oscilloscope or a dedicated mobile application (for example, AudioTool).
  2. Crossover frequencies: for front speakers, set HPF 60–80 Hzto unload them from low frequencies. Rear speakers can be trimmed higher - HPF 120–150 Hz.
  3. Channel balance: If there is an imbalance in the cabin (for example, the sound is shifted to the left), adjust the level of each channel separately using the test tone.

For fine tuning, use eQUALizer in the head unit or an external DSP processor. For example, a rise in frequencies in the range 2–5 kHz will add “air” to the vocals, and the correction will 200–500 Hz will remove the echo of the cabin.

💡

If your radio does not have a built-in equalizer, use the application ViPER4Android (requires root) or external processor type Dayton Audio DSP-408.

Maintenance and care: how to extend the life of your amplifier

Amplifier KICKS 4.160 designed for long service, but only if several rules are observed:

  • 🧹 Cleaning: Once every 6 months, remove dust from the ventilation grilles with compressed air. Do not use wet wipes!
  • 🌡️ Temperature: Avoid operating the amplifier at temperatures above +50°C (for example, in a closed car in the sun).
  • 🔌 Checking contacts: Once a year, tighten the power and ground terminals - oxidation increases the resistance.

If the amplifier suddenly stops turning on, check:

  1. Fuse on the positive wire (may blow out during a short circuit).
  2. Voltage at REM-input (must be 12 V when the radio is turned on).
  3. Integrity of the speakers (a break or short circuit in the load disables the protection).
⚠️ Attention: if the amplifier gets hot even at low volume, this is a sign of a faulty output transistors. Do not use it until repaired - this may cause a fire!
💡

Regular cleaning and temperature control will extend the life of the amplifier by 30–50%.

FAQ: answers to frequently asked questions

Is it possible to connect a subwoofer to the KICKS 4.160 in bridged mode?

Yes, the amplifier supports bridge mode (channels 1+2 or 3+4), but the load must be at least 4 ohms. A subwoofer with a 2 ohm impedance will require a separate monoblock.

Which fuse should I put on the positive wire?

A 60-80 A fuse is recommended, installed no further than 30 cm from the battery. Use AGU type (knife) for reliable contact.

Why does the amplifier turn on with a delay?

A delay of 1-2 seconds is normal - this is the protection response time. If the delay is more than 5 seconds, check the voltage at REM-input or replace the capacitor in the power supply.

Can KICKS 4.160 be used with 8 ohm speakers?

Yes, but the power per channel will drop to ~100 W. For 8 ohm speakers, it is better to choose an amplifier with a higher supply voltage (for example, KICKS 4.200).

How to reset your amplifier to factory settings?

On most models KICKS reset is performed by holding the button Mode for 5 seconds when turned on. If this doesn't work, turn off the power for 10 minutes.
