You now awn a Soundstream Amplifier, handcrafted in the USA, it is the result of a unique design and engineering philosophy.

To maximize the performance of your system, we recommend that you thoroughly acquaint yourself with its capabilities and features. Please retain this manual and your sales and installation receipts for future reference.

Soundstream amplifiers are manufactured with the highest quality control standards. When properly installed, they will provide you with many years of listening pleasure. Please record the following information which will help protect your investment should your amplifier ever need replacement or service

Prolonged listening at high /eve/s may result in hearing loss. Even though your new Soundstream amplifier sounds better than anything you've ever beard, exercise caution to prevent hearing damage.

WIRING

POWER AND GROUND

To assure maximum output from your amplifier, use high quality, low-loss power and ground cables. Soundstream amplifiers incorporate gold-plated barrier strips for maximum power transfer and protection from corrosion. The screw terminals back out for use with spade & ring terminals. Determine from the chart below the minimum gauge power and ground wire for your application.

Model	up to 10'	up to 20'
P203	10 or 12 ga.	10 ga.
P205	10 or 12 ga.	10 ga.

CIRCUIT BREAKERS/FUSES

EXTERNAL

Like all audio components, the Soundstream amplifiers must be fused near the battery A fuse or circuit breaker must be located within 18" of the battery This will prevent a fire in the event of a shorted cable. See the chart below to determine the value of your battery Fuse/circuit breaker.

INTERNAL

The Soundstream amplifiers are fused internally with automotive-type fuses. The fuse is accessible on the left side of the amplifier. Never replace the fuses with a higher value than what is supplied. This may result in amplifier damage and will void the warranty!

Model	Amplifier Fuses	Battery Fuse/Circuit Breaker
P203	(1) 30 amp automotive	40 amp
P205	(2) 20 amp automotive	50 amp

(Continued from page 8)

REMOTE TURN-ON

Connect the "Remote" to the turn-on lead from the source unit. When +12 volts is received, the amplifier will turn on.

SIGNAL CABLE

To guarantee optimum performance, use a high-quality cable that will be easy to install and has minimal signal loss.

SPEAKER CABLE

Use a high quality, flexible, multi-strand cable for best performance and longevity.

PROTECTION CIRCUITRY

Your Soundstream amplifier is protected against both overheating and short circuits by means of the following circuits:

• Main power supply fuses.
• Speaker output protection.
  • A fail-safe thermal protection circuit activating at WC.

NOTE: If you experience blown main power supply fuses, DO NOT increase values beyond the original values! Doing so will void your warranty and may damage your amplifier.

TROUBLESHOOTING

PROBLEM	CAUSE
No sound and LED is not lit	. no power or ground at amp. no remote turn-on signal• blown fuse “ear battery. blown amp power supply fuse
Repeatedly blown amp fuse, frequent activation of Thermal Protection Circuit	• check speaker configuration—impedance may be less than 2 ohms stereo or 4 ohms mono. speaker or leads may be shorted• verify adequate amplifier ventilation

SERVICE

Your Soundstream amplifier is protected by a limited warranty. Please read the enclosed warranty card.
