Precautions: Read First! · · · · · · · · · · · · If after reading the directions you feel uncomfortable about installing the amplifier in your car, or not equipped or competent to do so, you should have the amplifier installed by an authorized installer. It's your car! The negative battery terminal must be disconnected before any electrical connections are made. Be sure to choose a location that provides substantial ventilation for the amplifier. The most preferred locations would be in your car's trunk, under the front seats or on the back wall of a truck. The location chosen should provide at least 2" of clearance above the amplifier for adequate ventilation. If the amplifier is to be mounted vertically be sure that it is in a place where adequate air will flow along the length of its heatsink fins for cooling. NEVER mount the amplifier up side down, this will cause the heat to rise back into the amplifier causing thermal shutdown or possible permanent damage. NEVER mount the amplifier in a location that is subject to direct sunlight or exposed to moisture. Be sure to mount the amplifier to a strong, solid surface which will not give way under the stress of a sudden stop or accident. Make sure that the mounting screws will not penetrate the gas tank, brake and fuel lines, wiring or other critical parts of your car when installed. NEVER operate the amplifier without the proper power and ground wire 10 gauge minimum. NEVER operate the amplifier without proper fusing. Fuse holder must be located with in 0.5 meters from the battery. This fuse is to protect the car not the electronics. In case of a short, the fuse will blow instead of the wire burning up. Using other than the recommended fuse ratings at the battery and at the amplifier may cause damage to the amplifier and will void your warranty. Do not run wiring underneath or outside the car since exposure to the elements may cause the insulation to deteriorate rapidly, resulting in short-circuits and/or intermittent operation. 2 H-SA301 HYUNDAI · · · · · · · · · · All cables should be run beneath carpets and inside trim pieces. To help minimize interference, it is best to run the power cables along the opposite side of the audio(RCA) cables. Whenever wires pass through metal, rubber or plastic grommets must be used to prevent the metal from wearing through the installation and causing a short. Whenever possible, use cable ties, mounting clamps and similar wiring aids. (available from an electrical supply or auto parts store) Adding stress relief loops to wiring is also advisable to prevent straining or breakage. It is best to test the system before the amplifier is mounted and interior of car is reassembled. If the temperature inside your car reaches extreme levels(such as by sitting locked up for several hours in the hot sun or exposed to a very cold winter's day)the amplifier may go into protection mode and shut off. Leave the unit off until the ambient temperature returns to normal. The amplifier operates with any vehicle using a 12 volt negative ground system. If you are not sure of the type of electrical system in your vehicle, consult your authorized dealer or qualified mechanic. NEVER ground the speaker leads and NEVER allow the speaker leads to come in contact with each other. The Speaker wire should be at least 16. Remote turn on wire must be switched by the radio. If the radio does not have a remote turn on or antenna output, connect to wire that has a positive 12 volts output when the key is turned to the accessory position. If the amplifier does not turn off the battery will die. Do not listen to high volumes for extended periods of time or hearing damage may occur. CONTINOUS EXPOSURE TO SOUND PRESSURE LEVELS OVER 100dB MAY CAUSE PERMANENT HEARING LOSS. HIGH POWERED AUTOSOUND SYSTEM MAY PRODUCE SOUND PRESSURE LEVELS WELL OVER 130dB. USE COMMON SENSE AND PRACTICE SAFE SOUND. HYUNDAI 3 H-SA301 Installation MOUNTING: 1. After reading precaution, decide where you are going to install the unit. Also, see Fig.1. 2. Once the location has been determined, place the amplifier into position. Using a felt tip pen or pencil mark the four holes to be drilled for mounting. NEVER use the amplifier as a template for drilling. It is very easy to damage the amplifier surface in this manner. 3. Remove amplifier. Drill four 3.5 mm holes into mounting surface. If you want to mount the amplifier to MDF or wood panel, drill four 3.0m/m diameter holes into mounting surface. 4. If possible, test the system to ensure it is operating correctly before final mounting of the amplifier. 5. Mount the amplifier using the supplied 4 self threading screws. INSTALLATION DIAGRAM Fig. 1. HYUNDAI 4 H-SA301 CONNECTIONS INPUT CONNECTIONS · This amplifier will accept low level inputs. Low level is the same as line level. The low level signal is carried through RCA cables. It is preferred to use low level inputs to the amplifier if the head unit is equipped with the low level outputs. If not, you can use a "high to low converter" available through your local car audio shop. · Connect the low level/line level RCA cables from the head unit, or signal processor, to the line level input on the amplifier. See Fig.2 system wiring diagrams. Fig.2 HYUNDAI 5 H-SA301 POWER CONNECTIONS It is important to have good quality power and ground connections. Remember, to complete an electrical circuit, the ground connection is just as important as the positive power connection. Before any power connections are made, disconnect the ground cable at the battery. When the power supply lead, memory backup lead or ground lead are extended use a 5mm2 or larger automotive grade cable which will withstand friction and heat to safe grade against fires occurring as a result of short-circuiting. GND = Connect the proper gauge ground wire to the amplifier "GND" terminal. Locate the position on the chassis of the car to which the amplifier is to be grounded. The surface must be free from any paint or dirt. This can be accomplished with a small grinding bit, sand paper or wire wheel. NOTE: Do not ground the amplifier to the "frame of the car. The frame on most cars and trucks is not grounded to the chassis(body). Use Solder or a clamp ring to connect the ground wire. Pre-drill the prepped chassis to bolt the ground ring terminal with nut, bolt and lock washers. Insulate metal and connector with paint or silicon to prevent rust and oxidation. Silicon also works great to prevent nuts and bolts from working loose in a harsh environment of an automobile. Upon completion of the ground connection, grab wire or connector and confirm that it is a solid connection. To prevent engine noise, it is recommended to ground the head unit and other audio electronics in the same location. REM = Connect the remote wire (power antenna output) from the head unit to the remote turn-on wire of the amplifier. If the head unit is not equipped with a remote/antenna output, locate a wire that is controlled by the accessory position of the key. It is important to have the amplifier turn off with the radio or key. If the amplifier remains on, the result will most likely be a dead battery. 12V = Connect the proper gauge power wire to the amplifier "B+" terminal. Run wire to wards the fuse holder that is no greater then 0.5 meters from the battery. Remember, the fuse is to protect the safety of the car in the case of a short. Connect fuse holder to battery, but do not install fuse at this time. HYUNDAI 6 H-SA301 SPEAKER CONNECTIONS This amplifier can operate in one channel. The minimum impedance for single channel (mono) operation is 2 or 8 ohms. Connect the speaker wire to corresponding speaker output terminals of the amplifier. Be sure to have the positive wire from the speaker connected to the positive speaker terminal of the amplifier and the negative wire from the speaker connected to the negative speaker terminal of the amplifier. Reversing any of these connections will result in the speaker cones moving out of phase which causes bass cancellation. See Fig.3 Speaker Output Connections. Fig.3. HYUNDAI 7 H-SA301 ADJUSTMENTS 1.This amplifier is used to drive a subwoofer. The frequencies above the crossover point will be attenuated at 12dB /octave. Permits adjustment of the crossover frequency, by rotating the knob to select any frequency between 50Hz to 250 Hz as the crossover point. 2.Level adjustment-The sensitivity adjustment is to allow the amplifier to work with many different brands of head units. It allows input signal to vary between 200 millivolts to 6 volt from the head unit or other signal processor. Start by setting the sensitivity adjustment to the "MIN" (6 volts).Using a cassette or compact disc that you are familiar with ,turn on head unit to the 3/4 volume setting. Slowly turn up sensitivity adjustment towards the "MAX" (200 millivolts) using a flat head screw driver. Stop turning on the onset of distortion and turn back just a slight. The 3/4 volume setting is now the "maximum" volume for the head unit. The goal is to keep the level control to the lowest setting yet still have enough signal to drive the amplifier. This is done to prevent over driving the amplifier and to keep system noise to a minimum. It is important not over drive speakers (at point of distortion) this will cause permanent damage to the speakers. Also, if the amplifier itself is over driven, it could be damaged. 3. S.S.F - Subsonic Filter allows you to block (filter) ultra-low frequencies that your subs cannot reproduce. Set to ON position to activate the filter. The level of crossover frequency can be changed from 20 Hz to 50 Hz by rotating the knob. The frequencies below the crossover point will be attenuated at 12dB /octave 4.The "BASS" function can be selected to increase low frequency response output, or decrease frequency response output. The BASS is adjustable from 0 / 12dB boost at 50Hz. Fig.4.
