SPL 40 Component Speaker System

Congratulations on your purchase of the Soundstream SPL 40

Component Speaker System. When used with a high quality 2 ohm

rated power amplifier, the SPL 40 will provide exceptional

performance.

As with all high quality car audio components, professional installation

is recommended. Your dealer’s knowledge and experience can ensure

a problem-free, cosmetically integrated installation. If you plan on

installing the SPL 40 speaker system yourself, please review this

Owner’s Manual first before attempting installation. In addition, it’s a

good idea to keep the manual for future reference.

MOUNTING

SPL 4 Midrange / Woofer

The SPL 4 is an excellent performer with a combination of high

sensitivity, solid bass and smooth response throughout the audible

range.

•Lightweight Cone designed for good rigidity and high sensitivity

•2 Ohm Voice Coil for increased output

SPL 1 Aluminum Dome Neodymium Tweeter

The SPL 1 tweeter is a high performance 1” Neodymium tweeter

designed to deliver outstanding high frequency reproduction

•Black Aluminum 1" dome for improved power handling and

linear response

•Ferrofluid-immersed Voice Coil enhances heat dissipation

•Vented Aluminum Voice Coil Former for superb heat dissipation

and high power handling

SPL 4X Passive Crossover Network

The SPL 4X crossover consists of high quality, multi-element

components with a two position tweeter level control. This allows

tailoring high frequency output to the installation and individual

preferences.

•24 dB/octave Acoustic Summation Crossover Slopes

•Variable tweeter control for added flexibility

•Dynamic tweeter protection allows for improved power handling

and continuous output

•Ultra-low DCR Inductors for minimal signal loss (High power

Ferrite in woofer path)

2 Ohm Nominal System Impedance

The 2 Ohm impedance design of the SPL 40 system provides an overall

3 dB increase in output compared to a 4 Ohm design.

•Effectively a doubling of Sound Pressure Level -- with the same

amplifier voltage output

•More stable, phase coherent load than two 4 Ohm speakers

Flush Mounting:

1) Cut a 2 1/16” (52mm) diameter hole through the

mounting surface. If the surface is covered with

cloth or carpet, be careful not to tear or pull the

material. Sometimes it is a good idea to peel the

material away, and then trim it by hand.

2) Secure the cup in the mounting cutout by using

the spring clips and screw provided. Slip the

spring clips through the bottom of the cup and

tighten the screw until the cup is firmly seated.

See Figure 1.

3) Once the cup is secure, mount the tweeter into

the cup making sure to first pass the tweeter

wires through the openings in the cup. Turn the

outer swivel ring, (not the tweeter) clockwise to

lock it into place. See Figure 2. The tweeter

may be tilted approximately 15 degrees to

optimize dispersion and imaging.

INSTALLING

THE

TWEETER

The first step in a successful installation is thorough

planning. Choose the location for your speaker

components carefully. Follow these suggestions to

ensure proper imaging and the best performance:

•Select a location where each tweeter and

midrange/woofer can be mounted close to each

other. A good rule of thumb is a maximum of

one foot from cone to tweeter.

•Choose a location that offers the least

obstruction of sound to your ears.

•Try to mount the components on the same plane.

•Always check behind the chosen mounting

locations to make sure that there are no

obstructions (e.g., trunk springs, gas tank,

window tracks) or wires in the way, as well as to

make sure that there is ample support on which

to mount the components.

Surface Mounting:

1) Drill one 5/16" diameter hole for the tweeter lead wires and two pilot

holes for the mounting screws.

2) Attach the surface mount plate with two flat head screws.

3) Pass the lead wires through the hole. See figure 3.

4) Engage the locking holes on the back of the tweeter onto the tabs on

the plate and rotate counter-clockwise until locked. See figure 4.

MOUNTING

THE SPL 4X

CROSSOVER

The SPL 4 Midrange/Woofer can be mounted on

the front or rear of a panel; gaskets are provided

for both options. The bolt hole configuration will fit

a variety of American, European and Asian OEM

patterns making it ideal for direct placement. Best

performance is achieved when the speaker is

securely mounted to a door panel or rear deck.

There should be no gaps between the speaker and

the mounting surface, as this will impair its low

frequency performance. Be certain that both the

panel and the speaker are securely mounted to

prevent unwanted vibration.

1) Mark the speaker location by using the

template provided.

2) Cut the opening and debur the edges with a

file.

3) Hold the speaker in place against the

mounting surface and mark the mounting bolt

holes.

6) Drill the appropriate size hole for the screws

provided.

7) Place the SPL 4 into the trim ring, make the

speaker wire connections, then install the

speaker/trim ring assembly to the panel using

The SPL 4X Passive Crossover can be mounted in

virtually any location inside the vehicle. Be sure

not to mount the SPL 4X outside the vehicle, or in

a location where it may be exposed to dirt or

moisture (e.g., the engine compartment, inside a

wheel housing, at the bottom of a leaky trunk,

inside a door).

TWEETER

LEVEL

CONTROL

Tweeter Attenuation

The SPL 40 system has been designed to provide

optimum sound in a variety of installation locations. The

provided crossover allows for 2 positions of tweeter

level control, 0dB and -3dB. A switch under the plastic

crossover cover sets one of the two positions. The

factory setting is 0 dB.

SPL 4 Wiring Diagram

Figure 6 shows a diagram illustrating the wiring of the

SPL 40 Component Speaker System. It is important to

make sure that all connections are in phase; that is

positive (+) is connected to positive (+), and negative (-)

is connected to negative (-) since an out-of-phase

connection will cause a dislocated image and low bass

output. We suggest using premium cable. The

connectors provided with this system will accommodate

wire from 12 gauge to 16 gauge.
