USER’S MANUAL EV2.200 Two Channel High Power Car Audio Amplifier EV4.400 Four Channel High Power Car Audio Amplifier Congratulations on your purchase of a Sound Storm Laboratories EVOLUTION Amplifier. It has been designed, engineered and manufactured to bring you the highest level of performance and quality, and will afford you years of listening pleasure.
Introduction What is included? With the Sound Storm Laboratories EVOLUTION high power amplifier series, we are introducing two new models, both designed in the USA. This new series includes a 2-channel and a 4-channel amplifier. When first unpacking your new amplifier, please check first that the package contains all of the items below. If something is missing, contact the store where you purchased the player. These EVOLUTION models feature a low pass crossover, and the EV4.
Features About 2 Ohm operation Your new EVOLUTION amplifier features the following: Your EVOLUTION amplifier has been designed to operate efficiently at loads down to 2 Ohms. This means that you can install four 8 Ohm speakers per channel, when using parallel wiring.
General precautions Installation precautions Before installing and using your new Sound Storm Laboratories amplifier, please become familiar with all the information contained in this manual. Before you drill or cut any holes, investigate your car's layout very carefully. Take special care when you work near the gas tank, fuel lines, hydraulic lines and electrical wiring. Please keep this manual in a safe place for future reference. Never operate the amplifier when it is unmounted.
Mounting the amplifier 1. Find a suitable location in the vehicle in which to mount the amplifier. 2. Make sure there is sufficient air circulation around the intended mounting location. 3. Mark the location for the mounting hole screws by positioning the amplifier where you wish to install it. Use a scribe or mounting screw, inserted through each of the amp's mounting holes, to mark the mounting surface. If the mounting surface is carpeted, measure the hole centers and mark with a felt tip pen. 4.
Connecting the amplifier Before doing any wiring, look through this manual and identify the diagrams to follow for power, input and speaker connections for your particular installation. Be sure you understand all the connections before you proceed. 1. Connect the power ground terminal to the closest point on the chassis of the car. Keep this ground wire to less than 39" (100 cm) in length. Use 8 gauge (or heavier) wire. 2.
Low Level Input Wiring Low-level (RCA) input wiring is preferred for best audio performance. Always use a high-quality RCA cable for best audio performance. NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your amplifier at the same time! 2-Channel Amplifier EV2.
High Level Input Wiring, cont. The high level input(s) should only be used when your head unit lacks RCA outputs. If the RCA outputs are not present, connect the speaker outputs from the receiver to the high level input connector of the amplifier. Be sure to observe polarity to avoid audio phase problems. NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your amplifier at the same time! 2-Channel Amplifier EV2.
