In This Guide: Installing car speakers

often requires removal of door, dash

or rear window shelf interior panels to

access the speaker mounting points.

Component speakers require the

additional steps of installing a sepa-

rate tweeter and passive crossover

network. Follow these easy installation

steps to ensure proper installation of

your speakers.

Coaxial or Component Speakers

Coaxial speakers combine a cone speaker for

midrange frequencies with a tweeter for high fre-

quencies in a single speaker chassis. Many coaxial

speakers use high quality materials and ﬁt directly

into factory locations, simplifying installation and

delivering upgraded sound quality.

Component speakers have separate midrange and

tweeter drivers providing the ﬂexibility to mount

tweeters at the listener’s ear level. Components

also have a passive crossover network that routes

appropriate frequencies to the midrange and

tweeter respectively, which improves power han-

dling of the speakers and optimizes sound produc-

tion. Consider component speakers when you are

in pursuit of the highest caliber music experience.

Match RMS Power Ratings

RMS power ratings represent a realistic expectation

of a product’s performance. To ensure quality sound

production, match the ampliﬁer’s RMS power output

with the speaker’s RMS power handling. Overpower-

ing speakers can overheat the speaker’s voice coils

causing premature failure. Under powering speakers

may cause sound distortion. As an example, if the

speakers are rated at 50 watts RMS, choose an am-

pliﬁer that provides between 40 to 60 watts RMS to

each speaker. A little more power (up to +25%) over

the speaker’s RMS power handling is okay, as it adds

‘headroom,’ or reserve power, to the audio system

when the music gets complex and/or loud.

Sound Deadening Treatment

Consider installing sound damping and vibration

control materials in the doors, trunk, rear shelf and

ﬂoor of the car. These adhesive sheet materials

install easily on metal and plastic to reduce the road

noise and vibration from interior panels to create a

quieter, more enjoyable listening environment. By

adding mass (weight) to the panel, any vibrations

are suppressed, transferring energy from the speak-

ers into great sound rather than annoying buzzing,

vibrating and rattling of interior panels.

Upgrading Speakers

Sound Deadening Reduces Vibrations and Rattles

from Sheet Metal and Plastic Panels

Component Speakers in a Kick Panel Location

Closely match CEA-2031 Speaker Power Handling

Wattage with CEA-2006 Amplier Output Power Wattage.

If CEA ratings are not available, always look for the ‘RMS’

ratings to guide product matching.
