Frequently Asked Questions - L 6X.2 Helix

What is the power handling of the Helix L 6X.2?

The speaker handles 80 Watts RMS and 160 Watts max power.

What type of tweeter does the L 6X.2 use?

It uses a 20 mm / 0.75 inch PEI dome tweeter with a neodymium magnet for clear treble.

What is the crossover configuration?

The L 6X.2 has an integrated crossover with a 6 dB/octave slope. No separate crossover is included.

How do I connect the speaker to an amplifier?

Connect the amplifier output to the speaker terminals, ensuring correct polarity: positive to positive and negative to negative. The positive wire is marked with a red stripe.

Can I adjust the tweeter level?

No, the L 6X.2 does not have tweeter level adjustment. This feature is only available on the separate crossover of the L 62C.2 model.

What is the recommended mounting depth?

The required mounting depth is 58 mm / 2.30 inches. Ensure adequate clearance behind the speaker.

What materials are used in the woofer cone?

The woofer cone is made of polypropylene with a long-excursion rubber surround for durability and low distortion.

Is the grille included?

Yes, a grille is included with the speaker system for protection and aesthetics.

How do I test the speakers before final installation?

Operate the system at low volume before final mounting to verify each speaker works. This prevents damage from hidden issues.

What should I avoid when mounting the speakers?

Avoid mounting on uneven surfaces, oversized holes, or locations where water can splash. Also, ensure no interference with windows, seat mechanisms, or torsion bars.

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.

1. Always make sure that the speaker will fit into the intended mounting location and that there is adequate depth for the magnet system.

2. 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.

3. 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.

4. Make sure that the crossovers are mounted properly.

5. Do not mount the speakers and crossovers where water may splash on them.

6. 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.

1. 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).
2. 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.
3. 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 for connecting HELIX crossovers (except L 6X.2)

Connect the amplifier and the speakers to the crossover as described in the following:

1. At first connect the amplifier to the appropriate inputs of the crossover (-IN +) .

2. Connect the wires of the woofer to the appropriate inputs of the crossover ( -WF+ ).

3. Then connect the wires of the tweeter to the crossover ( -TW + ). It is possible to change the loudness level of the tweeter by repositioning a jumper on the inside of the crossover:

+2 dB: If the jumper will be set to this plug position the level of the tweeter is increased by +2 dB.
0 dB: If the jumper is set to this plug position the tweeter has the optimum level for most applications.
-2 dB: If you choose this plug position, the level of the tweeter is reduced by 2 dB.

Attention: Ensure that all components 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 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.

General instructions for mounting HELIX speaker systems

Once you have tested the complete speaker system and have confirmed correct operation, turn off the audio system and prepare all loudspeakers for final mounting.

1. Place the loudspeaker in the mounting position as shown in the illustration "Mounting the woofer".

2. Fix the speaker with its mounting ring in its installation place and check if all screws are properly aligned with the fixing holes. Use the included screw clips to secure the screws. Tighten all screws evenly.

3. Attach the grille to the mounting ring.
