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 before shipping and is guaranteed against manufacturing defects.
For a proper performance and to ensure full warranty coverage, we strongly recommend getting this product installed by an authorized HELIX dealer.
If you choose to perform your 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 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. 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 a 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.
7. Avoid low-frequency cancellation caused by air leakage between the speaker basket and the mounting surface (e.g. mounted on a bent or uneven surface or mounted in an oversized hole).
8. 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 pieces of advice.
9. 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 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 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 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 white lettering.

General instructions for connecting the HELIX “Flex-Crossovers”

The crossover of the PR K165.2 component kit offers two configuration options.
Option 1: Connecting the crossovers in vehicles with mounting positions of the tweeter and woofer close to each other, e.g. in the car door.

Option 2: Connect the crossovers in vehicles with separate mounting positions of the tweeter and woofer, e.g. tweeter in the A-pillar and the woofer in the car door.

• For further information regarding the connection of the crossovers see the section “Connecting the Flex-Crossover” in this manual.

Flex-Crossover

Installation

Tweeter mounting

Option a:
OEM integration

1. Preparing the tweeter
2. Fix the tweeter in the original mirror triangle, e.g. with an appropriate adhesive or sealant.

Option b:
flush mount

Option c:
angled mounting with optionally available mounting pod PR ATP25

Attention: The OEM spacer is a very precise fit and therefore difficult to remove again. Please check carefully before mounting whether this installation pod should be used.

Woofer mounting

Connecting the Flex-Crossover

Option 1: Mounting positions within proximity
Connecting the crossovers in vehicles with mounting positions of tweeter and woofer close to each other, e.g. in the car door.

Option 2: separate mounting positions
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.

1. Press the acrylic covers together with slight pressure and pull them off towards the top.
2. Remove the two jumpers and the 4 screws (red marked). Then fold the circuit board in the middle into two parts.
3. Pull the carrier plate apart to the side.
4. Reinsert the circuit boards in the carrier plate and screw them back in place with the previously loosened screws. Then connect the loudspeakers and signal source.
5. At least, reinstall the acrylic covers. Do not install the circuit boards without the housing. Risk of circuit!

Connecting the Flex-Crossover

Tweeter level adjustment:

The crossover allows to optimization of the level of the connected tweeter internally by repositioning the tweeter-level jumper. Therefore remove the acrylic cover of the tweeter crossover, pull the jumper straight upwards, and reinsert it to the desired position.

• 0 dB: The tweeter has the optimum level for most applications.
• 3 dB: The level of the tweeter is reduced by 3 dB.
• 6 dB: The level of the tweeter is reduced by 6 dB.
