High-Low adapter set Plug & Play for subwoofer on power quadlock connection | Option

The integration of car hi-fi components into existing original sound systems is becoming increasingly complex due to intelligent radio diagnostic systems and the lack of preamplifier outputs on the factory radio. With the HLM-SUB-PQUADLOCK, an active subwoofer can be easily retrofitted to a power quadlock connection.

Attention! Some SEAT vehicles have a different assignment despite the Powerquadlock connection! If anything is unclear, please send us a picture of your(!) Powerquadlock for checking.

The most intelligent high-low converter in its class:

Thanks to the integrated ADEP.3 circuit, which bypasses the radio diagnostics system, error messages or even the omission of individual functions (such as faders) are a thing of the past.
Distorted music signals and an increased distortion factor, which can occur in conjunction with conventional high-low converters, are prevented by the intelligent ADEP.3 circuit. In addition, the load on the car radio amplifier is reduced and power consumption is cut by up to 70%.

Smart signal detection

Its "Double Activation Circuit" also generates a +12 V remote signal to switch on connected amplifiers in two different ways. It either recognises the DC potential on the speaker outputs of standard factory car radios or uses integrated signal recognition with variable input sensitivity, which can also be activated.
The "Power Save Mode", which switches off the remote output if there is no input signal for longer than 2 minutes, is also part of the standard equipment. This is because many vehicles with "CAN" or similar bus systems leave the car radio "invisibly" activated for up to 45 minutes, even if you have left the vehicle in the meantime.

High Resolution-capable

The HLM generates a high-quality pre-amplifier signal from the loudspeaker signal of the car radio or amplifier of an original sound system and thus enables the simple connection of additional amplifiers. Its particularly wide transmission range of 18 Hz to 80,000 Hz guarantees excellent sound and makes it High Resolution-capable.
