General instructions
General instructions for installing a HELIX speaker system
- To prevent damage to the speakers and possible injury, read this manual carefully and follow all installation instructions. This product has been checked for proper function prior to shipping and is guaranteed against manufacturing defects.
- For a proper performance and to ensure full warranty coverage, we strongly recommend to get this product installed by an authorized HELIX dealer. If you choose to perform your own installation read the following information and precautions carefully.
- Failure to follow the stated precautions may result in personal injury and / or damage to the audio system or vehicle.
- Always make sure that the speaker will fit into the intended mounting location and that there is adequate depth for the magnet system.
- Check for adequate space between speaker and window, window crank, power window mechanism, seat, rear deck torsion bars, and other items which may interfere with the speaker`s mounting. This is very important if any hole cutting is required. Detailed size information is indicated in the dimension section of this manual. Take care that the mounting surface is flat and free from all obstructions.
- Ensure that the loudspeakers are correctly connected (phase), i.e. plus to plus and minus to minus. Exchanging plus and minus may result in significant loss of sound quality.
- Make sure that the crossovers are mounted properly.
- Do not mount the speakers and crossovers where water may splash on them.
- The quality of the installation has a significant effect on the overall performance of the speaker system. Treat each installation step with a high degree of attention.
- Avoid low frequency cancellation caused by air leakage between the speaker basket and the mounting surface (e.g. mounted on a bended or uneven surface or mounted in an oversized hole).
- Mounting panel reinforcement may be necessary in some cases in order to ensure a stable, torsion-free and even surface. This can be achieved by mounting the speaker on a metal or wooden sub-baffle behind the body or door panel. Consult an installation specialist for further advices.
- In most cases you can use the original speaker mounting locations in the doors, body panels or the rear deck. If these are not available you have to prepare your own secure installation place. Due to their structural integrity and accessibility the precut mounting holes should be used whenever possible. Information on a proper mounting can be found in the section “Installation” of this manual.
IMPORTANT: Never cut any metal that is an integral part of an automobile`s safety or structural car body.
General instructions
General instructions for connecting HELIX speaker systems
-
We strongly recommend that you operate the complete audio system at low volume before final installation. So you can check whether each speaker is working before securing the loudspeakers into their mounting locations.
-
Make sure that all speaker wiring is fully protected from cutting or wear at sharp edges, which can lead to short circuits that may damage your head unit, amplifier and/or speaker system.
-
Make sure that all speaker wires are long enough in order to avoid any mechanical stress on the wires or the connectors.
Attention: Ensure that the loudspeakers are correctly connected (phase), i.e. plus to plus and minus to minus. Exchanging plus and minus will result in a significant loss of sound quality. -
The positive leads of the loudspeaker system are marked with a red stripe.
General instructions for connecting the HELIX “Flex-Crossovers”
-
The crossovers of the PF K165.2 / PF K130.2 / PF K100.2 component kit offer two configuration options.
-
Option a: Connecting the crossovers in vehicles with mounting positions of tweeter and woofer close to each other, e.g. in the car door.
-
Option b: Connecting the crossovers in vehicles with separate mounting positions of tweeter and woofer, e.g. tweeter in the A-pillar and woofer in the car door.
-
-
For further information regarding the connection of the crossovers see section “Connecting the Flex-Crossover” in this manual.

- Option c: angle mount
Woofer mounting
Connecting the Flex-Crossover
-
Option a: Connecting the crossovers in vehicles with mounting positions of tweeter and woofer close to each other, e.g. in the car door.
-
Option b: Connecting the crossovers in vehicles with separate mounting positions of tweeter and woofer, e.g. tweeter in the A-pillar and woofer in the car door.
Ensure that all components are correctly connected (phase), i.e. plus to plus
and minus to minus. The positive leads of the loudspeaker system are marked
with a red stripe.
Adjusting the level of the tweeter:
- The crossover allows to optimize the level of the connected tweeter.
- Therefore adjust the slide switch which is located at the top of the crossover to the desired position.
- Std.: The tweeter has the optimum level for most applications (tweeter level reduction PF K165.2: -3 dB / PF K130.2: -3 dB / PF K100.2: -4 dB).
- Max.: The tweeter is driven with the maximum level.
