Product Usage Instructions

General Instructions for Installing HELIX Loudspeakers
- To prevent damage to the speakers and ensure proper installation, please follow these instructions carefully:
Speaker Fit and Mounting
- Before installation, ensure 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 the speaker and window, window crank, power window mechanism, seat, rear deck torsion bars, and other items that may interfere with the speaker’s mounting.
- Take care to ensure that the mounting surface is flat and free from obstructions.
Polarity and Wiring
- Ensure that the loudspeakers are correctly connected in polarity.
- Exchanging the positive (+) and negative (-) leads may result in a significant loss of sound quality.
- The positive leads of the loudspeakers are marked red.
- Make sure all speaker wiring is fully protected from cutting or wear at sharp edges to avoid short circuits that may damage your head unit, amplifier, and/or speaker system.
Connection Wires
- Verify that all connection wires are long enough to avoid any mechanical stress on the wires or connectors.
Mounting Components
- Mount all components properly according to the provided instructions.
Avoid Water Exposure
- Do not mount the components where water may splash on them to prevent damage.
Installation Quality
- 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.
Air Leakage Prevention
- Avoid low-frequency cancellation caused by air leakage between the speaker basket and the mounting surface.
- This can be achieved by ensuring the speaker is mounted on a flat and even surface, free from bends or unevenness.
- Additionally, avoid mounting the speaker in an oversized hole.
Mounting Panel Reinforcement
- In some cases, mounting panel reinforcement may be necessary to ensure a stable, torsion-free, and even surface.
- This can be achieved by mounting the speaker on a metal, plastic, or wooden sub-baffle behind the body or door panel. Consult an installation specialist for further advice.
Original Speaker Mounting Locations
- In most cases, you can use the original speaker mounting locations in the doors, A-pillars, body panels, or the rear deck.
- If these are not available, you will need to prepare your secure installation place.
- Whenever possible, use the precut mounting holes for proper mounting. Information on proper mounting can be found in the Installation section of this manual.
FAQ
- Q: Can I install the HELIX COMPOSE Speaker Systems myself?
- A: While we strongly recommend getting this product installed by an authorized HELIX dealer for proper performance and full warranty coverage, you can perform your installation by following the provided instructions carefully.
- Q: How can I prevent water damage to the components?
- A: Avoid mounting the components where water may splash on them. Choose a location that is protected from water exposure.
- Q: What should I do if there is inadequate space for speaker mounting?
- A: If there is inadequate space between the speaker and other items that may interfere with mounting, consider using a different location or consult an installation specialist for further advice.
- Q: How can I ensure a stable and even mounting surface?
- A: To ensure a stable and even mounting surface, you may need to use mounting panel reinforcement. Consult an installation specialist for guidance on mounting panel reinforcement techniques.

General instructions

General instructions for installing HELIX loudspeakers
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 installedby 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 in polarity. Exchanging plus and minus may result in significant loss of sound quality. The positive leads of the loudspeakers are marked red.
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.
Verify that all connection wires are long enough in order to avoid any mechanical stress on the wires or the connectors.
Make sure that all components are mounted properly.
Do not mount the components 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, plastic 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, A-pillars, 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. 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.

Tweeter level adjustment

The crossover allows to optimization of the level of the connected tweeter internally by repositioning the tweeter-level jumper.
Therefore open the crossover housing, pull the jumper straight upwards, and reinsert it to the desired position.
The correct tweeter level setting strongly depends on the location of the speakers.
Then confirm the level by listening to the speakers and modify the jumper setting if needed.
- +2 dB: The level of the tweeter is increased by 2 dB.
- 0 dB: The tweeter has the optimum level for most applications.
- -2 dB: The level of the tweeter is reduced by 2 dB.
- -3 dB: The level of the tweeter is reduced by 3 dB.
- -4 dB: The level of the tweeter is reduced by 4 dB.
- -5 dB: The level of the tweeter is reduced by 5 dB.
