Your new American LEGgarnElifier comes complete with all required mounting hardware. When determining a suitable location in your vehicle for the amp, please remember that it is a high-power electronic device capable of generating high heat.
For this reason, alap chaase a lacalian in JIIur vehicle which hIS law libralian,adequale IInliiatian,a minimum aI dust,and na maisture. Be sure to mount the amp in such a manner as to allow reasonable airtlow over the cooling fins.
Mark the lacatian far the maunling screw hales by positioning the amp where you wish to install it and use a scribe (or one of the mounting screws) inserted in each of the mounting holes to mark the mounting surtace. If the mounting surtace IS carpeted, measure the hole centers and mark with a felt tip pen.
lefare lIIe.ing ta drill the maunling hales, take nate allIIJ wires, lines ar allier devices in JIIur vehicle which may be lacated behind tile maunting .. rllce! Then drill pilot holes in the mounting surtace for the mounting screws and insert them. Tighten the screws securely.
ta JIIur amplifier, plelSe abserve the
Use at least 8 gauge wire for power and ground connections.
Wire the amplifier directly to the car battery.
For the ground connection, use the shortest possible wire to a good chassis ground point.
American LEGACY Series amplifiers feature built-in fuse systems. These fuses protect both the amplifier and the electrical system in your vehicle from tault conditions. If you ever need to replace the fuse in your American LEGACY Series amp, use a fuse of exactly the same type and rating. A different type or rating of fuse may result in damage or fire.
troubleshooting
p'rotectlon clrcultru The built-in protection circuitry in the American Legacy Series amplifiers will disable the amplifier if it senses an input overload, a speaker short circuit, or extreme temperature conditions.
When the protection circuit is activated by any of these conditions, the Protection LED will be illuminated.
If this occurs, carefully inspect the system to determine the source of the problem.
• If the shutdown was a result of a thermal overload condition, allow the amplifier to cool down before attempting to restart it.
• If the shutdown was a result of an input overload, or speaker short circuit, be sure to correct the condition before restarting.
The amplifier can be restarted by turning the remote power OFF and then ON again.
liD autput. Confirm that all terminal strip connections are secure and tight.
Check both in-line and built-in fuses. Both the + 12Vand the Remote terminals must have +12V referenced to chassis ground.
Confirm that the audio signal sourca (car radiO, equalizer, etc.) is connected and is supplying output signal. To check if the amp is supplyinQ signal, unrlug the cables from the signal source (but leave them plugged into the amp). Bnetly tap the center Pin of each 0 the disconnected RCA plugs with your linger. This should produca a noise (teedback) in your speakers.
Only Dne clulnnel works. Conlirm that all terminal strip connections are secure and tight.
Check the Balance control on the head unit (or other source) to verify that it is set to its midpoint.
If you are using the Low Level RCA input, reverse the input plugs at the amplifier (i.e., switch the L with the R). If the channels which is silent switches to the other side, the problem is either in the head uniVother source or the connecting cables.
Welk autp.t. Readjust the Input Level Control(s) to better suit the input signal .
IIDIse In tile audlD. If the noise is a ''whine· whose pitch follows the engine speed, confirm that the amplifier and any other signal sourcas (head unit, etc.) are properly grounded.
If the noise is a "clicking" or ·popping" noise whose rate follows the engine speed, this usually means that the vehicle is equipped with resistor spark plugs and wires, or that the ignition is in need of service.
Check the rounting of the speaker and input wires to make sure they are not adjacent to wires which interconnect lights and other accassories.
If the above steps fail to improve or clear noise interterence, the system should be checked by a professional mobile audio installer.
precautions Do not operate the amplifier when it is unmounted. Attach all audio system components securely within the automobile to prevent damage, especially in an accident.
Do not mount this amplifier so that the wire connections are unprotected, or in a pinched condition, or likely to be darnaged by nearby objects.
Before making or breaking power connections in your system, disconnect the vehicle battery. Confirm that your head unit or other equipment is turned off while connecting the input jacks and speaker terminals.
If lOU need to replace the power fuse, do so only With a fuse identical to that supplied with the amplifier. Using a fuse of a different type or rating may result in damage that isn1 covered in the manufacturer� warranty.
