INTERNAL

The REFERENCE amplifiers are fused with automotive-type fuses. In the event of blown powersupplyfuses, the “FaulY’indicator on the top panel will light. The fuses are accessible via a plastic plug on the bottom of the amplifier. See the chart below to determine the fuse value. Never replace the fuses with a higher value than what is supplied. This may result in amplifier damage

and will void fbe warranfy~

Amplifier Fuse Values

Amplifier	Amplifier Fuse	Battery Fuse /
		Circuit Breaker

REFERENCE414s	(2) 25 amp automotive	60 amp

REFERENCE&l&	(2) 30 amp automotive	80 amp

REMOTE TURN-ON

Connect the “Remote” to the turn-on lead from the source unit. When+I2 volts is received, the amplifier will turn on.

SIGNAL CABLE

Use a high-quality cable that will be easy to install and has minimal signal loss to guarantee optimum performance. Soundstream’s DL.1 and SL,l are ideal when using the Unbalanced RCA inputs. (While using the Balanced DIN input on the Reference644s, use the cable supplied with the BLTTY or BLT4TY).

SPEAKER CABLE

The REFERENCE amps will accept up to 8 gauge speaker cable. Use a high quality, flexible, multi-strand cable for best performance and longevity. Soundstream Speaker120 & 160 (12 and 16 gauge) are ideal.

INSTALLATION AND MOUNTING

1.AMPLIFIER LOCA T/ON

The REFERENCE amplifiers employ highly efficient circuitry and a unique Chassisink’” design to maintain lower operating temperatures. Additional cooling may be required if the amplifier is located in a tightly donfined area or when driving especially low impedance loads at extremely high levels.

When mounting the amplifier, it should be securely mounted to either a panel in the vehicle or an amp board or rack that is securely mounted to the vehicle. The mounting location should be either in the passenger compartment or in the trunk of the vehicle, away from moisture, stray or moving objects, and major electrical components. TO provide adequate ventilation, mount the amplifier so that there are at least two inches of freely circulating air above and to the sides of it.

2.SWITCHES

Set the Coherent StereoTM/Mixed-Mono/Bridged Mono and crossover switches on the bottom of the amplifier to the appropriate positions before bolting down the amplifier (see pages 20 - 25). Be sure to replace the hole plugs.

7 MOUNTING THE AMPLIFIER

a. Using the amplifier as a template. mark the mounting surface. b. Remove the amplifier and drill the holes.

c. Mount the amplifier to the surface using the provided hardware.

4.WIRING

a.Run and connect the audio signal and remote turn-on cables to the amplifier from the source unit.

b.Carefully run the positive cable from the amplifier to a fuse or circuit breaker within 18” of the battery

c.Connect the fuse or circuit breaker to the battery Leave the circuit breaker off or the fuse out until everything is bolted down.

d.Secure the ground cable to a solid chassis ground on the vehicle. It may be necessary to sand paint down to raw metal for a good connection.

e.Double check each and every connection!

g.Re-connect the fuse or circuit breaker.

5. POWER UP

Power up the system and look at the red High Power LED: there may be a 2 -3 second delay from the time the the source unit is turned on to the time that the LED on the amp turns on, which is normal. Once the amplifier power LED is on and the source unit is playing. you should have sound coming from the speakers.

414s, 644s specifications

Soundstream Technologies has made significant waves in the automotive audio industry with its innovative products, especially the 644s and 414s models. These two amplifiers are designed for audiophiles seeking high-quality sound and reliability in their car audio systems.

The Soundstream Technologies 644s is a 4-channel amplifier that delivers clean, powerful sound with a peak power output of 400 watts, making it ideal for driving a full range of speakers. It features a Class A/B design, which ensures high efficiency and minimal distortion, resulting in an impressive audio experience. This amplifier is equipped with adjustable crossovers, allowing users to customize the sound to fit their preferences and ensure optimal performance for both highs and lows. Additionally, the 644s has a built-in bass boost feature, enhancing low-end frequencies for those who appreciate deep, resonating bass in their music.

On the other hand, the Soundstream Technologies 414s is a robust 2-channel amplifier that outputs up to 300 watts of peak power. Like the 644s, the 414s also employs Class A/B technology, which contributes to its impressive sound dynamics and low distortion levels. This model is designed for users looking to power two speakers or a single subwoofer, providing clear and reliable audio output. The 414s features a variable gain control, which helps users balance the sound levels according to their preferences.

Both models boast a sleek design with an aircraft-grade aluminum chassis that not only enhances their durability but also contributes to effective heat dissipation, ensuring long-lasting performance. The built-in protection circuitry prevents overheating and short-circuiting, protecting both the amplifier and the audio components connected to it.

Additionally, both the 644s and 414s incorporate professional-grade connectors and wire terminals that ensure secure, low-resistance connections. This attention to detail in design and technology makes them a reliable choice for serious audio enthusiasts.

In summary, the Soundstream Technologies 644s and 414s amplifiers embody the company’s commitment to delivering high-quality audio solutions. With their feature-rich designs, effective sound customization options, and robust build quality, these amplifiers remain a popular choice among car audio aficionados looking for exceptional sound performance on the road.
