Frequently Asked Questions - Helix E 6X.2 Audiotec Fischer

What is the difference between the E 6X.2 coaxial and the E 62C.2 component system?

The E 6X.2 is a coaxial speaker with a tweeter mounted on top of the woofer, while the E 62C.2 is a component system with separate woofer, tweeter, and external crossover. The coaxial is easier to install, but the component system offers better sound staging.

Can I install the Helix E 6X.2 in my car doors?

Yes, the E 6X.2 is designed for car door installation, but ensure the mounting depth (65 mm) fits without interfering with windows or mechanisms. Use the original speaker locations if possible.

What tools do I need for installation?

You will need screwdrivers, wire cutters/strippers, a drill (if new holes required), and the included screws and clips. Always test the system before final mounting.

How do I connect the inline crossover?

The inline crossover connects between the amplifier and the speaker. Connect the amplifier output to the crossover input, then the crossover output to the speaker terminals. Ensure polarity is correct.

Can I use the E 6X.2 without an external amplifier?

Yes, but for best performance, use an external amplifier. The speaker handles up to 60W RMS, so a head unit may not provide enough power.

What is the recommended break-in period?

No specific break-in period is stated, but typically speakers improve after 10-20 hours of moderate use. Avoid maximum volume initially.

How do I clean the speaker grille?

Gently remove the grille (if detachable) and wipe with a soft, dry cloth. Do not use liquids or abrasive cleaners.

Is the speaker waterproof?

No, the speaker is not waterproof. Avoid mounting where water may splash on it to prevent damage.

What should I do if the speaker sounds distorted?

Check for clipping from the amplifier (reduce gain), ensure the speaker is not overpowered, and confirm all connections are secure. Also verify that the mounting surface is sealed properly.

Does the warranty cover damage from improper installation?

No, the warranty covers manufacturing defects only. Damage from overload, improper use, or unauthorized installation is not covered.

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

4. 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.

5. 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).

6. 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.

7. In most cases you can use the original speaker mounting locations at 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.

Important:

Never cut any metal that is an integral part of an automobile's safety or structural car body.

General instructions for connecting HELIX speaker systems

We strongly recommend that you operate the complete audio system at low volume before final installation. This will allow a trial listening test before securing the loudspeakers into their mounting locations.

Make sure that all speaker wiring is fully protected from cutting or wear at sharp edges. This can lead into a short circuit which might damage your head unit, amplifier and/or speaker system.

Make sure that all speaker wires have sufficient length in order to reach the speaker terminals without stress on the wire or connectors.

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 the loudspeaker 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 in the right position to the fixing holes. Use the included screw clips to secure the screws. Tighten all screws evenly.
3. Attach the mesh to the mounting ring.
