Simple black-and-white diagram of a sun with radiating lines and a central cross (no text or symbols)INTENDED USE
- This product is only designed for the use in a vehicle with 12 volt on-board voltage with negative ground and functions as an amplifier for audio signals. In principle, this product should be used for installation in subwoofer enclosures.
- Please use the product only in its intended manner. Any other use may lead to damage to the product or in the vicinity of the product.
DISPOSAL
If you have to dispose of the device, please note that no electronic devices may be disposed of with household waste. Dispose of the device in a suitable recycling facility in accordance with local waste regulations. If necessary, consult your local authority or your dealer.
INSTALLATION
- You will find a cutout template in the scope of delivery, which you can use to mark the amplifier opening in the housing.
- Then connect the subwoofer to the amplifier module. Make sure that the polarity is correct. Refer to the next page for the minimum load impedance of the subwoofer (s).
- Then use the six enclosed screws to attach the amplifier module to the enclosure.
OUTPUT POWER & LIMITER
The POWER4 amplifier module can be used in different enclosure types. However, the following should be noted here: With regard to the cooling of the module, larger enclosures, especially bassreflex systems with sufficient air circulation inside the enclosure, are not a problem. In the case of very small or closed enclosures, due to the very small internal volume or the lack of air exchange, sufficient cooling is not guaranteed when the module is operated at the highest power level.
Therefore, the module has a special feature: depending on the type of enclosure and the prevailing air circulation and the load capacity of the connected subwoofer, the output power can be adjusted in 3 stages. In this way, the module can be ideally adapted to the performance of the subwoofer and the thermal conditions and overheating can be prevented.
To adjust for optimal performance, remove the cover (as described in the figure below). You will find a three-way switch in the top center under the cover. This is in position A ex works, which corresponds to the full output power without a limiter. Now you can simply switch to select the desired power level (A, B or C).
A: Full Power Mode (Switch position up)
1 x 460 W/RMS @ 4 Ohm at 14,4 V In this switch position, only 4 ohm operation is recommended!
B: Limiter 1 Mode (Switch position middle)
1 x 260 W/RMS @ 4 Ohm at 14,4 V In this switch position, only 4 ohm operation is recommended!
C: Limiter 2 Mode (Switch position down)
1 x 190/280 W/RMS @ 4/2 Ohm at 14,4 V

ELECTRICAL INTERCONNECTION
BEFORE CONNECTING
For the professional installation of a sound system, car audio retail stores offers appropriate wiring kits. Ensure a sufficient profile section (refer to the table on the next page) and a suitable fuse rating and the conductivity of the cables when you purchase your wiring kit. Clean and remove rust-streaked and oxidized areas on the contact points of the battery and the ground connection. Make sure that all screws are fixed tight after the installation, because loose connections cause malfunctions, insufficient power supply or interferences.
CAUTION
Before you start with the installation, disconnect necessarily the GROUND connection wire from the battery to avoid any risk of electric shocks and short circuits.
+12V
Connect the +12V terminal +12V with the +12V pole of the vehicle's battery. Use a suitable cable with a sufficient cross section (refer to section 5 on this page).
2 REM Conn
Connect a turn-on signal or the turn-on remote signal of your head unit (REM) with the REM terminal of the amplifier module. Use therefor a suitable cable with a sufficient cross section (0,5 mm²). Hereby the amplifier module turns on or off with your head unit. If you use the AUTO TURN-ON function (refer to page 23, section 13), the REM terminal does not need to be connected.
3 GND Conn
Connect the GND terminal with a suitable contact ground point on the vehicle's chassis. The ground wire must be as short as possible and must be connected to a blank metallic point at the vehicle's chassis. Ensure that this ground point has a stable and safe electric connection to the negative “-”pole of the battery. Check this ground wire from the battery to the ground point if possible and enforce it if required. Use a ground wire with a sufficient cross section (refer to the table and the recommendations on the next page) and the same size like the +12V power supply wire.
4 DEVICE FUSES
The amplifier module has two device fuses, each with 25 A.
ADDITIONAL CABLE FUSE (NOT INCLUDED)
Install an extra fuse (not included) for the +12V power cable near the battery to secure the power cable. The distance between the fuse and the battery should not exceed 30 cm. The fuse size must be adapted to the cable cross-section of the installed power cable (see table below).
IMPORTANT: The fuse on the battery does not protect the amplifier module, but the cable between the battery and the amplifier module against short circuits.

DESCRIPTION OF OPERATION
7 LINE INPUT (Low Level 5.5 \~ 0.2 V)
Connect the RCA inputs to the head unit/car stereo using a RCA audio cable. If available, use the subwoofer output of the head unit/car stereo for this.
HIGH LEVEL INPUT (High Level 40 \~ 1.5 V or 15 \~ 0.5 V)
If your head unit/car stereo does not have any RCA pre-amplifier module outputs, you can use the high level input as a signal input. To do this, connect the loudspeaker cable of the head unit/car stereo to the enclosed cable connector accordingly.
INPUT VOLTAGE
9 With this switch you can switch the input sensitivity of the high level input from 40 \~ 1.5 V to 15 \~ 0.5 V.
CAUTION
Never operate LINE INPUT and HIGH LEVEL INPUT at the same time.
10 The high level input is equipped with EPS PRO (Error Protection System) so that no functions are impaired or error messages are written to the vehicle memory when connected to OEM factory radios. The input resistance of the EPS PRO protection circuit can be set with the EPS LOAD switch. The following settings are possible:
10 R: Recommended for the outputs of a head unit/car stereo if a loudspeaker was previously operated with them.
150 R: Recommended for factory sound systems from f.e. VW / Audi / Skoda, with f.e. a built-in amplifier/booster.
600 R: Recommended for factory sound systems from f.e. BMW, with f.e. a built-in amplifier/booster or if the high level input is operated together with a loudspeaker.
11 LEVEL
This controller determines the input sensitivity of the amplifier module. Pay attention to the CLIP LED and turn back the LEVEL controller if it lights up yellow. You may have to adjust the INPUT VOLTAGE switch accordingly for the best result.
12 STATUS LEDs
The yellow CLIP LED lights up when the input signal is set too high. Please refer to the information under LEVEL [ 11 ]. If the blue PWR LED lights up, the amplifier module is ready for operation. If the red PRO LED lights up, there is a malfunction. Then follow the instructions in the section TROUBLE-SHOOTING on page 24.
13 AUTO TURN-ON
If your head unit/car stereo does not have a remote turn-on wire (see page 21, section 2), you can use the amplifier module's automatic turn-on and turn-off function. This function works only in combination with the HIGH LEVEL INPUT [8] and in two ways, which can be set with the AUTO TURN-ON switch:
DC: Preferred method.
SIGNAL: Should be only used if method DC is not working.
14 PHASE SHIFT This switch can be used to change the phase from 0^ to 180^ in order to adapt the subwoofer signal to the full-range loudspeakers.
15 LOW PASS
This controller limits the frequency of the audio signal upwards. The crossover frequency is adjustable from 40 to 120 Hz.
16 SUBSONIC
This controller limits the ultra low and not audible frequencies of the audio signal downwards to avoid mechanical and electrical overloading on the subwoofer. The crossover frequency is adjustable from 5 to 35 Hz and depends on the size of the subwoofer.
17 BASS BOOST
This controller adjusts the bass boost from 0 dB to 6 dB at 45 Hz.
18 REMOTE
Connect here the cable of the included bass level remote controller. This can be used to adjust the bass level from the driver's seat, for example.

| Is the high pass filter of the relevant channel pair set too low on the amplifier module?First turn the high pass controller fully clockwise. Now start playback on the head unit. Then turn the high pass controller slowly counter-clockwise until you can hear a clean sound from the tweeters and produce a balanced sound together with the woofers/mid-range speakers. Make sure that the woofers/mid-range speakers are set correctly with the respective high pass and low pass controllers. |
| Amplifier moduleS ACTIVATES THE PROTECTIVE CIRCUIT / THE PROTECT LED ILLUMINATES |
| Check the following steps: |
| Short circuit on the speaker cablesFirst disconnect all speaker cables from the amplifier module. Use a multimeter to check the ohmic impedance of each loudspeaker by measuring between its plus and minus lines. With standard loudspeakers the value fluctuates between 3 and 5 ohms. The values for low-resistance subwoofers can be lower.The measurement shows a resistance value of less than 0.5 OhmsThen there is a short circuit. Remove the wiring of the affected loudspeaker at its connections. Now use the multimeter to check the ohmic impedance directly at the loudspeaker connections by measuring between the plus and minus connections.The measurement shows a resistance value of more than 0.5 OhmsThe speaker is fine, so the speaker wire appears to be defective and causing a short circuit. Replace the defective speaker cable.The measurement shows a resistance value of less than 0.5 OhmsThe speaker appears to be defective and is shorting out. Replace the defective speaker. |
| The load impedance of the loudspeakers or the subwoofer is too lowCompare the ohmic impedance of the connected loudspeaker or subwoofer with the technical specifications of the amplifier module. For example, if the amplifier module is only designed for 2 or 4 ohm operation, no loudspeaker with less than 2 ohms may be connected. |
| The cross-section of the power cables is too smallIf the cable cross-section is too small, this leads to an increased ohmic resistance and thus to a voltage drop (voltage loss). This indicates that the amplifier module consumes more power. The increased power consumption results in a significantly higher heat development and the amplifier module switches to thermal protection mode. Therefore, observe the recommended cable cross-sections in these instructions and, if necessary, lay power cables with a larger cable cross-section. |
| The amplifier module is overheated (refer also to page 17)The heat sink of each amplifier module requires sufficient air circulation to be able to dissipate the heat generated during operation. If necessary, change the installation position in favor of better cooling of the amplifier module or ensure better air circulation at the installation location.Turn off the sound system and wait about half an hour for the amplifier module to cool down again. With very hot outside temperatures and strong sunlight, enormous heat develops inside the vehicle. The amplifier module then activates its thermal protection circuit to prevent damage. After cooling down, the amplifier module works properly again. |
ATTENTION: All instructions in this troubleshooting refer to the entire sound system and its individual components. The features of your device may not match the functions described in the notes. Then skip this point and move on to the next one.
