GETTING STARTED

• Turn off the audio system. It is also

advisable to disconnect the negative (–)

terminal of your vehicle’s battery whenever

performing installation work.

• Before cutting, drilling or inserting any screw,

check clearances on both sides of the planned

mounting surface. Also check for any potential

obstacles, such as window tracks and motors,

wiring harnesses, etc. Check both sides of the

vehicle, many vehicles are not symmetrical!

• Always wear protective eyewear.

SPEAKER PLACEMENT CONSIDERATIONS

Grilles are not included with C1 speakers, as they

are designed for installation into OEM (factory)

speaker locations, located behind factory grilles.

Should you need grilles, you will need to purchase

aftermarket grilles separately.

WARNING

Prolonged exposure to sound pressure levels in

excess of 100dB can cause permanent hearing

loss. These high-performance loudspeakers can

exceed this level. Please exercise restraint in their

operation in order to preserve your ability to enjoy

their fidelity.

WARNING

Double check the clearance for both speakers

before proceeding. Many cars are different from

one side to the other!

SPEAKER PLACEMENT CONSIDERATIONS

A component system gives you the ability to place

the woofer and tweeter separately in your vehicle

interior. This can be good or bad, depending on how

it’s done. As a general rule, the tweeters should be

placed relatively close to the woofers for best tonal

balance and most coherent imaging (the closer, the

better). Any separation greater than 8 inches (20 cm)

is likely to result in degraded sound quality.

Avoid placing tweeters where they will be blocked

by objects in the interior of the car (including seated

occupants). When selecting a mounting location,

look at both sides of the car to make sure that this

location is clear on both sides.

You can always experiment with tweeter

placement before committing to a final mounting

location. Simply connect the rest of the system and

allow plenty of wire length for the tweeters. Using

hook and loop or similar material, attach the tweeters

in different locations until you find the one where

they perform best.

Woofers will usually be placed into factory

speaker locations. If you have some woofer mounting

flexibility, keep the following in mind: Lower

mounting locations, such as the lower front corner

of a door or a kick-panel provide the greatest path

length distances for the sound emitted by the

woofer. For this reason, they are generally more

desirable than higher mounting locations. Higher

mounting locations often result in extreme near-

side soundstage bias which compromises the stereo

listening experience.

TWEETER INSTALLATION

C1 tweeters have been designed for surface

or flush-mounting. Before choosing a method,

carefully inspect the desired mounting location

to determine which method will work best.

Surface-Mount: uses the supplied surface-

mount fixture and requires the drilling of three

holes (one for the wires and two for the mounting

screws). This application is useful when mounting

the tweeters to a panel that has insufficient clearance

behind it for the tweeter’s magnet structure.

Flush-Mount: yields a custom-installed

appearance and requires a 1-1/2-inch (38

mm) diameter hole to be cut in the vehicle

panel, with at least 0.40-inch (10 mm) of

clearance behind the mounting surface for

the tweeter and up to 1.45-inch (37 mm) for

the stud bolts used to mount each tweeter.

TWEETER PROTECTION

The C1 crossover networks are equipped with

an advanced electronic tweeter protection circuit

designed to minimize the possibility of tweeter

failure. This electronic device monitors current going

to the tweeter and will disconnect the tweeter from

the signal when it senses overload. Should this occur

while listening to the audio system, simply reduce the

volume for a few seconds and the protection circuit

will reset itself automatically.

CROSSOVER NETWORK INSTALLATION

The crossover networks supplied with your C1

System should be installed in a dry location inside

your vehicle. DO NOT INSTALL THEM INSIDE

OF A DOOR! Doors often get wet on the inside,

which can damage your crossover networks and

could potentially damage your entire sound system.

Use plastic cable ties or a similar fastener to securely

mount each crossover to avoid coming loose in the

event of a collision, sudden jolt or repeated vibrations

during normal use. Make sure that your mounting

location will not cause damage to wiring or any other

vital component of your vehicle.

TWEETER CONNECTIONS

Run the wire leads from the crossovers to

the tweeter mounting locations and to the speaker/

amplifier outputs. Then connect the harness wire

leads to the speaker/amplifier outputs and tweeters,

observing correct polarity. See Diagram C below

for details.

WARNING

It is absolutely vital that your component

tweeter is connected, as shown in Diagram C.

Failure to connect the tweeter as shown will

result in damage which is NOT covered under

warranty. Only use in-line filters clearly marked

“C1-075cthp”.

SURFACEMOUNT INSTALLATION

1) Remove the vehicle panel and check to ensure that

the mounting screws will have adequate clearance.

2) Place the surface-mount fixture on the

vehicle panel at the desired mounting location

with the mounting screw holes positioned

vertically, at twelve and six o’clock.

3) Mark the location of the two mounting screw

holes and the approximate center of the

right rectangular cutout (for the wires).

4) Using a 1/16-inch (1.5 mm) drill bit, drill a pilot

hole through the panel at the two screw locations.

5) Using a 1/4-inch (6 mm) drill bit, drill

the hole for the tweeter’s wires at the

location you marked in step 3.

6) Screw the surface-mount fixture to the

vehicle panel using the supplied #6

sheet metal screws (hand-tighten).

7) Feed the tweeter wires through the rectangular

hole in the mounting fixture and the 1/4-inch hole

you drilled in the panel. Then, snap the tweeter

into the surface-mount fixture.

8) Connect the tweeter’s wires to the wire leads from

the crossover, observing correct polarity.

9) Re-install the vehicle panel, taking care to

route the new wiring so as not to interfere

with any vehicle mechanisms (window

mechanisms, for example).

FLUSHMOUNT INSTALLATION

1) Detach the preinstalled surface-mount

fixture by inserting a small flat screwdriver

into the slots behind the tweeter flange

and carefully pry open to release.

2) Remove the vehicle panel and check the desired

mounting location to ensure that there is adequate

clearance behind the panel for the tweeter’s

magnet structure and mounting hardware.

3) Carefully cut a 1-7/16-inch (37 mm) diameter hole

in the vehicle panel. This will achieve a snug fit and

allow the tweeter flange to conceal the cut line.

4) Select a suitable length stud bolt for your panel’s

thickness and screw its short end into the rear of the

tweeter using the fixed M4 nut to tighten.

5) Insert the tweeter from the front of the panel (do

not attach the spring clip at this time).

6) Attach the spring clip from behind the panel using

the supplied M5 nut and tighten by hand until the

tweeter is tight on the panel. Do not overtighten.

8) Connect the tweeter’s wires to the wire leads from

the crossover, observing correct polarity.

9) Re-install the vehicle panel, taking care to

route the new wiring so as not to interfere

with any vehicle mechanisms (window

mechanisms, for example).

Speaker Installation in Factory Locations:

Your new speakers have been designed to install,

without modifications, into most vehicles with

OEM speaker locations that accept a 6.50-inch (165

mm) speaker. Many factory 6.50-inch speakers use

four mounting screws, which will line up with the

mounting holes on your C1-650cw woofers.

Adaptor rings are included for installation into

many GM, Honda and other vehicles or those

equipped with oversized 6.75-inch speaker openings.

Simply remove any unnecessary mounting tabs from

each adaptor ring and install, as shown in Diagrams

F and G (page 9).

It is absolutely vital that the speaker frame fits into

the mounting hole cleanly. This must be checked prior

to tightening the screws. Never force the frame into

a hole that is too small, and do not attempt to tighten

the speaker onto an uneven surface. This will damage

your speakers.

The speaker should fit so that air does not leak

around the mounting flange. Air leaks will cause a

severe degradation in sound quality. Seal any air leaks

with an automotive-grade sealant material.

WARNING

Hand-tighten the screws evenly in a criss-cross

pattern to avoid bending the speaker frame or

stripping the mounting screws.

Speaker Wiring:

If you will be using the factory speaker wires, it may

be necessary to change the terminations. This may

be accomplished by using an adaptor plug or simply

by cutting the factory connector off and using the

supplied crimp connectors to terminate the speaker

wires. The larger connector is for the positive terminal

and the smaller connector is for the negative terminal

of each C1-650cw.

If you choose to run new speaker wires, protect all

wiring from sharp edges by carefully routing them,

securing them and using grommets and loom where

appropriate. If you are running wires into a door, use

existing factory wiring boots whenever possible. If

you are drilling new holes, file their edges and install

rubber grommets into each hole. Wires running into

car doors should be covered with a protective, flexible

PVC sleeve. Make sure that the wires will clear door

hinges and other structures in the door.

WARNING

Double check the clearance for both speakers

before proceeding. Many cars are different from

one side to the other!
