Features
Memphis Audio built a 50 year legacy in the audio industry engineering the highest quality products to produce
the best possible listening experience for our fans and loyal supporters. To fully appreciate our products we
recommend taking the time to read and follow the instructions in this manual. As always, we recommend all
installations and service be performed by an authorized Memphis Audio dealer.
• 2 stereo stable / 4 mono ˜ ˜
• High & low level inputs
• 0/6/12dB bass boost
• Bridgeable & tri-mode operation
• Protection circuitry: overload, short circuit, thermal & reverse polarity
Bridgeable & Tri-Mode Operation
Street Reference amplifiers can be used in stereo, bridged or tri-mode operation. Tri-mode operation means that a pair of
speakers are wired in the conventional stereo manner while a subwoofer is simultaneously connected to the bridged terminals
of the same two channels. This is useful for simple 2-channel systems that require a subwoofer in addition to the full range
speakers
Nickel Plated Connectors
Ensures solid electrical connection that resist corrosion
Fully Variable High & Low Pass Crossovers
Fully variable crossovers promote installation ease and save the cost of outboard crossovers. Additionally, thy may be used in
conjunction with outboard passive or active crossovers depending on the complexity required by the system. The 12dB per
octave slope offers roll-off above or below the selected frequency.
Protection Circuitry
Protects against overload, short circuit, thermal and reverse polarity. These protection features are designed to protect the
amplifier from misuse as well as from common causes of amplifier failure.
LED Light
Blue light indicates that the amplifier is working normally. If the light is not illuminated or is glowing red, consult the
troubleshooting section of the manual.
For optimal performance, Memphis recommends using only Memphis Connection accessories. Outfitting
your system with properly sized Memphis Connection wire and accessories will dramatically boost your
listening experience and increase the durability of your Memphis Audio products.
Check out our full line of Street Reference speakers and subwoofers to create a complete Memphis
Street Reference system.
Street Reference amplifiers feature a MOSFET power supply with a 12dB per octave crossover to ensure the most
accurate musical reproduction. All models feature a fully variable crossover with 12db per octave slopes allowing
you the ability to tailor the sound to best fit your speakers and listening preferences.

STREETREFERENCE
When troubleshooting your amp, speaker and speaker wires should be tested first.
For your safety, always inspect the mounting location carefully to ensure you are not drilling into any electrical,
hydraulic, fuel or fluid lines. Always check your speaker load with a multi-meter before connecting the amplifier.
Connecting any speaker load lower than the rated impedance of the amplifier will result in damage to the amplifier.
Damage of this nature is NOT covered under warranty. Please pay close attention to what connections are made to
the amplifier.
If you are uncertain or uncomfortable proceeding with your installation, please contact your local
authorized Memphis Audio Dealer
No Output:
• Confirm all wiring is firmly connected.
Both +12V and REM terminals must have +12 Volts present and GND must be connected to chassis’ ground or to
the negative battery terminal.
• Confirm the signal source is connected and supplying an output signal. To confirm the amp is working, connect
an RCA patch cord to the line inputs of the amplifier (do not connect the other end of the patch cord). Briefly tap
the center pin of each disconnected RCA with your finger. This should produce a noise (brief static or hum) in
the speakers.
• If the amp is hot, check the speaker impedance or load. The total minimum impedance of all speakers should
not be lower than the rating of the amp.
Only One Channel Works:
• Confirm the speaker terminal strip connections are firmly connected.
• Check “balance” control on your signal source.
• If using RCA Low-Level inputs, reverse the input plugs at the amplifier. If the channel that is silent reverses
position, the problem is in the source unit or connecting cable.
Weak Output
• Check input sensitivity control adjustment.
Unwanted Noise
• Whine that increases and decreases with engine speed - confirm the Amp & Source unit are grounded properly.
• Clicking or popping noise at a rate that follows engine speed - this is often induced by the vehicles ignition system.
Confirm that the vehicle is equipped with resistor spark plugs and wires. The ignition system may need service.
• Noise can be caused by routing speaker input wires too close to the light wires and other accessory wires in the
vehicle. Re-route wires to avoid unwanted interference.
• If above steps do not improve/reduce noise, the system should be checked by a professional audio installer at a
Memphis Authorized Dealer.
Red LED is Illuminated
• Speaker or wire is shorted • Battery voltage too low
• Battery voltage too high • Amplifier has overheated due to improper ventilation
