Subwoofers Ural Cube - This is a popular solution for car enthusiasts who want to improve the sound of their audio system without radically altering the interior. Compact dimensions adapted to vehicle niches Nissan Cube, and balanced acoustic characteristics make them popular among owners of this unusual hatchback. But how to choose the right model among the line? Ural, install and configure it correctly to get deep bass without distortion? In this article we will look at all the nuances - from technical specifications to practical tips for integration into a standard audio system.
Feature Ural Cube lies in its versatility: the manufacturer offers models for both amateur use and more advanced music lovers. However, not all subwoofers are equally well suited to acoustic conditions. Nissan Cube — here it is important to take into account the volume of the cabin, the location of the speakers and even the upholstery material. We will analyze which parameters are critical when choosing, and what you can ignore so as not to overpay for unnecessary options.
Subwoofer Specifications Ural Cube: what is important to know
Ruler Ural Cube includes several models that differ in power, speaker size and cabinet design. Key parameters to pay attention to:
- 🔊 Speaker size: 8 to 12 inches. For Nissan Cube 10-inch models are optimal - they provide a balance between bass depth and compactness.
- 📊 Sensitivity (dB): The higher this number (usually 85-92 dB), the more efficiently the subwoofer converts power into sound. For low-power radios, it is important to choose models with a sensitivity of 90 dB or more.
- ⚡ Impedance (Ohm): most subwoofers Ural have an impedance of 4 ohms, but there are also 2-ohm options for powerful amplifiers.
- 🔋 Housing type: closed (for clear bass) or bass reflex (for higher volume). B Cube Closed cases work better due to the specifics of the interior.
One of the key points is RMS power (not to be confused with peak!). For Ural Cube it varies from 150 to 500 W. The rule of thumb here is that the power of the amplifier should be 10–20% higher than that of the subwoofer to avoid distortion. For example, if the subwoofer is rated at 300W RMS, the amplifier should output 350-400W.
No less important frequency range. A good subwoofer should reproduce frequencies from 20 Hz (the lower limit of human hearing) to 150–200 Hz (the upper limit of bass). Models Ural Cube typically cover a range of 25–150 Hz, which is sufficient for most music genres.

| Ural Cube-10P | 10 | 300 | 89 | 4 | With bass reflex | 15 000 |
Model Ural Cube-10S - the optimal choice for the Nissan Cube due to its balanced characteristics and compact dimensions, which allow it to be installed in a standard niche behind the rear seat. More powerful options (eg. Cube-12P) will require modifications to the interior or installation in the trunk, which is not always convenient.
⚠️ Attention: When choosing a model with a bass reflex (Cube-10P or Cube-12P) keep in mind that for correct operation you will need to fine-tune the bass reflex tuning frequency (usually 35–40 Hz). Incorrect settings will result in boomy bass.
Subwoofer installation Ural Cube in Nissan Cube: step by step instructions
Installing a subwoofer in Nissan Cube has its own nuances due to the non-standard shape of the cabin and limited space. We will consider two installation options: in a niche behind the rear seat and in the trunk.
Option 1: Installation in a niche behind the rear seat
This is the most popular solution, as it saves space in the trunk. Suitable models Ural Cube-8A or Cube-10S.
Remove the niche trim (carefully so as not to damage the clips)
Lay the power cable from the battery (cross-section at least 4 mm²)
Install a fuse next to the battery (rated 20–30% higher than the maximum current)
Lay the signal cable from the radio (avoid laying next to power wires)
Attach the subwoofer housing to standard points or via an adapter -->
To connect you will need:
- 🔌 Power cable (red, cross-section 4–8 mm²) with fuse.
- 📶 Signal cable (shielded, for example Belden 1855A).
- 🔧 Terminals and connectors for a reliable connection.
- 🛠️ Tool: screwdrivers, pliers, drill (if you need to drill holes for mounting).
Pay special attention grounding. The optimal place is a bolt on the body next to the subwoofer installation site. Before connecting, strip the contact area down to bare metal and use ground terminal with star washer for better contact.
Option 2: Installation in the trunk
If you have chosen a powerful model (for example, Cube-12P), it will have to be installed in the trunk. What's important here is:
- 📏 Accommodation: The subwoofer must be firmly secured so as not to move when moving. Use standard fasteners or make a metal frame.
- 🔇 Isolation: To avoid rattling, glue the subwoofer body with vibration-absorbing material (for example, StP Vibro).
- 🔌 Cable routing: The wires must be securely fastened and not dangle. Use corrugation or plastic clamps.
⚠️ Attention: When installing a subwoofer in the trunk Nissan Cube Please note that the rear door has a non-standard shape. Check whether the subwoofer housing does not interfere with the door opening, especially if you have a model with a bass reflex (it requires additional space for “breathing”).
Before final installation, test the subwoofer at minimum volume. If you hear extraneous noise or rattling, double-check the case fastening and the quality of the grounding.
Connecting a subwoofer to a standard radio: diagrams and nuances
B Nissan Cube The standard radio usually does not have a line output (RCA) for the subwoofer. In this case, there are three connection options:
- Via high level amplifier input (using wires from the rear speakers). Suitable for most amplifiers Ural.
- Via high-to-low converter (For example, AudioControl LC2i). Allows you to avoid quality losses.
- Replacing the original radio for model with
RCA-output (for example, Pioneer DEH-S4200BT).
Let's consider the first option in more detail, since it is the most budget-friendly. You will need:
- Remove the original radio (use pullers to Nissan).
- Find the wires going to the rear speakers (usually gray and gray-black for “+” and “–”, respectively).
- Connect them to the high-level inputs of the amplifier (marked as
Speaker InorHigh Level). - Adjust the amplifier sensitivity (
Gain) so that there is no distortion at maximum volume.
If you choose the second option with a converter, keep in mind that it allows you to:
- 🎛️ Adjust the signal level separately for the subwoofer.
- 🔄 Use function AccuBass to restore bass lost during compression of audio files.
- 🔇 Avoid interference from on-board electronics.
How to check the polarity of speaker wires?
Connect a 1.5V battery to the speaker wires. If the diffuser moves forward, the polarity is correct. If it retracts, swap “+” and “–”.
Setting up the subwoofer Ural Cube: step by step guide
Correct setting is the key to high-quality sound. Start with basic parameters:
- Setting the cutoff frequency (
Low-Pass Filter): for most models Ural Cube optimally 80–100 Hz. If the subwoofer drones, lower the frequency to 70 Hz. - Phase setting (
Phase): Play music with clear bass and switch the phase (0° or 180°). Select a position that produces deeper bass. - Level adjustment (
Gain): Set the radio volume to 75%, then gradually increaseGainon the amplifier until distortion appears. Step back 10-15%. - Settings
Bass Boost: If there is such a function, start at 0 dB. If necessary, increase to +6 dB, but no more - this will lead to overload.
For fine tuning, use test tracks with a known frequency range. For example:
- 🎵 30 Hz: Should feel like vibration, not sound.
- 🎵 50–60 Hz: Clear, deep bass.
- 🎵 80–100 Hz: “warmth” of sound, transition to mid-range frequencies.
If the subwoofer makes strange sounds (such as grunting), check:
- 🔌 Quality of grounding (possibly oxidation of contacts).
- ⚡ On-board network voltage (must be at least 13.8 V when the engine is running).
- 🔊 Amplifier sensitivity (possibly too high
Gain).
The ideal subwoofer setting is achieved when the bass is audible, but does not stand out from the background of other frequencies. If rear seat passengers feel vibration more than they hear sound, the bass level is too high.
Common problems and their solutions
Even after proper installation and configuration, problems may occur. Let's look at typical cases and ways to eliminate them.
| Problem | Possible reason | Solution |
|---|---|---|
| Subwoofer won't turn on | No power or signal Remote |
Check the fuse, voltage at B+ and signal Remote (should be 12V when turning on the radio) |
| The bass booms | Incorrect cutoff frequency or phase | Reduce Low-Pass Filter up to 70Hz, check phase setting |
| Extraneous noise (background) | Interference from on-board electronics | Use shielded cables, add a noise filter |
| The subwoofer is getting warm | Too tall Gain or low impedance |
Reduce gain level, check amplifier impedance match |
If after all the manipulations the problem remains, check:
- 🔧 Speaker mount: Loose screws may cause rattling noise.
- 🔊 Diffuser integrity: Cracks or tears will cause distortion.
- 📶 Signal cable quality: Damaged shielding causes interference.
⚠️ Attention: If the subwoofer Ural Cube starts wheezing at high volume, immediately reduce the sound level. This is a sign of overload, which can damage the speaker. Check the setting Gain and connection impedance.
