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. 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. 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. Check out our full line of Street Reference speakers and subwoofers to create a complete Memphis Street Reference 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. Subsonic Filter A subsonic filter has been provided to filter out unwanted subsonic bass frequencies below the audible range of the subwoofer. This feature helps improve the amplifiers overall performance since power is not wasted reproducing frequencies beyond the speaker operating range Remote Level Control Remote allows you to control the level of the subwoofer remotely by controlling the output level of the amplifier Installation Information Memphis Audio recommends the installation of our products to be performed by an Authorized dealer. Attempting an installation project on your own or through an unauthorized source may result in damage to your products and may potentially void your warranty. Amplifiers are generally mounted in the hatch/trunk area of your vehicle or behind the seat of most pick up trucks. Select a location that provides adequate ventilation. Amplifier should be secured using the screws provided. Warning 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 Troubleshooting When troubleshooting your amp, speaker and speaker wires should be tested first. 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 high · Battery voltage too low · Amplifier has overheated due to improper ventilation Power Supply Connections Install the fuse at the battery last! CAUTION CAUTION Use conventional stranded copper wire for all connections. Finish the ends of the wires at the amp and vehicle with proper size terminals. Poorly made connections and/or inadequate wire size will generate excessive heat and may lead to equipment failure. 12 Volt + Connection Make the 12V+ connection directly at the positive battery post using the proper wire size and fuse listed below, The fuse should be installed within 18" of the battery. This fuse is vital to protecting the vehicle from damage in the case of a dead short. Model Amp Kit SRX250.1V 8 SRX500.1V 4 SRX750.1V 4 Ground Connection: SRX1200.1V 4 Make ground connection directly to the chassis of the vehicle as close to the amp as possible. Make sure this connection is made with the same wire size as used for the 12 volt connection. Ensure that all dirt, grease, paint and coatings are removed prior to attaching the ground wire to chassis. Remote Turn On Remote turn on should be connected to the source unit's remote turn on lead or power antenna output wire. When using the power antenna wire, make certain it does not lose power when any source other than the radio is selected. Power Connections Features & Controls SRX250.1V // SRX500.1V // SRX750.1V // SRX1200.1V Gain The gain control is NOT a volume control. The gain control adjusts the amount of signal required to drive the amplifier to full output. With the gain at full clockwise rotation, less signal voltage is required to drive the amp to full output. With the gain at full counter clockwise rotation, more signal voltage is required to drive the amp to full output. For optimal performance, set the gain control to minimum. Low Pass Filter The lowpass crossover/filter is designed to remove high frequency information from a speaker. This is generally used to prevent mid bass speakers or subwoofers from trying to reproduce mid and high frequency information that they are not designed to reproduce. The crossover frequency is adjustable from 50Hz-250Hz and use a 12dB per octave slope. To engage the LPF slide the switch to the position marked LPF. Frequency selection is made by rotating the dial: Clockwise raises the frequency, counter clockwise lowers the frequency. Most subwoofers should be set between 80Hz and 100Hz depending on how low the mid-bass or midrange drivers are capable of playing. Bass Boost Bass boost is switchable to off (0dB) or +6dB and +12dB. Boost should be used with discretion. Electronically enhance boost places an additional load on the amplifier and the speakers they are connected to. Remote Level Control The amplifiers have inputs for a remote level control (RLC). This will allow the amplifier input level to be adjusted from the listening position. Connect the RJ45 jack on the front to the amplifier. Install the control module in front of the vehicle in a location that is easily accessible to the driver. Subsonic Filter The subsonic filter utilizes an internal 12dB per octave slope and is variable from 15Hz-50Hz Speaker Connections Continued SRX250.1V // SRX500.1V // SRX750.1V // SRX1200.1V The RCA jacks marked Low Input should be connected to the low level outputs of your source unit or signal processor. High level(speaker level) inputs are provided as well.
