PLANNING YOUR INSTALLATION
It is important that you take the time to read this manual and that you plan out your installation carefully. The following are some considerations that you must take into account when planning your installation.
Cooling Efficiency Considerations:
Your JL Audio amplifier employs an advanced type of heat management, called RealSink???. This feature takes advantage of convection and radiation effects to remove heat from the amplifier circuitry. For optimum cooling performance, the vertical heat sinks located at the back of the amplifier should be exposed to as large a volume of air as possible. Enclosing the amplifier in a small, poorly ventilated chamber can lead to excessive heat

Speaker loads below 1.5?? nominal are not recommended and may cause the amplifier output to distort excessively.
Speaker connections to the 1000/1v2 are straightforward and take place at the far right of the front panel. You will notice that there are two
connections. This is to facilitate multiple speaker wiring. The two positive and two negative connections are connected in parallel inside
the amplifier. Connecting two speakers, each to one set of positive and negative terminals, will result in a parallel speaker connection. If only connecting one pair of speaker wires, it is not necessary to use both sets of connections.

There are three status indicator lights on the top of the amplifier. These are as follows:
1)iPowerw (Green): lights to indicate that the amplifier is turned on and operating normally.
2)iThermalw (Red): lights to indicate that the amplifier has exceeded its safe operating temperature, putting the amplifier into a self- protection mode, which reduces the power output of the amplifier. The red light will shut off and the amplifier will return to normal,
3)iLow ??w (Amber): lights to indicate that the impedance of the speaker load connected to the amplifier is lower than the optimum

Input Sensitivity Level Setting
Intelligent Power Supply (R.I.P.S.) allow delivery of their rated power when connected to any load impedance from 1.5 - 4?? per channel and when connected to a charging system with any voltage from 11 - 14.5V. This design is beneficial for many reasons. One of these reasons is ease of setup. Because each JL Audio amplifier will always deliver the same amount of power within its operational range of impedances and supply voltages, the
maximum, unclipped output is very predictable. This makes setting the gain structure via the input sensitivity controls very simple. Following the directions below will allow the user to adjust
the input sensitivity of the amplifier(s) simply and easily in just a few minutes using equipment which is commonly available in installation bays.

???How do I properly set the input sensitivity on my amplifier???
Please refer to Appendix A (page 14) to set the input sensitivity for maximum,
???My amplifier doesn???t turn on???
Check the fuse, not just visually, but with a continuity meter. It is possible for a fuse to have poor internal connections that cannot be found by visual inspection. It is best to take the fuse out of the holder for testing. If no problem is found with the fuse, inspect the
Check the integrity of the connections made to each of the i+12VDCw iGroundw BOEiRemotewUFSNJOBMT. Ensure that no wire insulation is pinched by the terminal set screw and that each connection is tight.
Check to make sure there is +12V at the ???Remote??? connection of the amplifier. In some cases, the
???I get a distorted / attenuated sound coming out of the speaker(s)???
Check the speaker wires for a possible short, either between the positive and negative leads or between either speaker lead and the vehicle???s chassis ground. If a short is present, you will experience distorted and/or attenuated output. The iLow ??w light will illuminate in this situation. It may be helpful to disconnect the speaker wires from the amplifier and use a different set of wires connected to a test speaker.
Check the nominal load impedance to verify that the amplifier is driving a load between 1.5 - 4??. JL Audio monoblock amplifiers have two ???+??? positive connections and two
impedance between 3 - 8??.
Check the input signal and input signal cables to make sure signal is present at the ???Amplifier Inputs??? and the cables are not pinched or loose. It may be helpful to try a different set of cables and/or a different signal source to be sure.
???My amplifier???s output fluctuates when I tap on it or hit a bump???
Check the connections to the amplifier. Make sure that the insulation for all wires has been stripped back far enough to allow a good contact area inside the terminal block.
Check the input connectors to ensure that they all are making good contact with the input jacks on the amplifier.
???My amplifier shuts off once in a while, usually at higher volumes???
Check your voltage source and grounding point. The power supply of the 1000/1v2 will operate with charging system voltages down to 10V. Shutdown problems at higher volume levels can occur when the charging system voltage drops below 10V. These dips can be of very short duration making them
FYUSFNFMZEJGGJDVMUUPEFUFDUXJUIBDPNNPO%$WPMUNFUFS
To ensure proper voltage, inspect all wiring and termination points. It may also be necessary to upgrade the ground
wire connecting the battery to the vehicle???s chassis and the power wire connecting the alternator to the battery. Many vehicles employ small (10 AWG - 6 AWG) wire to ground the battery to the vehicle???s chassis and to connect the alternator to the battery. To prevent voltage drops, these wires should be upgraded to 4 AWG when installing amplifier systems with main fuse ratings above 60A. Grounding problems are the
leading cause of misdiagnosed amplifier ???failures.???
???My amplifier turns on, but there is no output???
Check the input signal using an AC voltmeter to measure the voltage from the source unit while an appropriate test tone is played through the source unit (disconnect the input cables from the amplifier prior to this test). The frequency used should be in the range that is to be amplified by the amplifier
FYBNQMF)[GPSBTVCCBTTBQQMJDBUJPOPSL)[GPSBGVMM
range /
Check the output of the amplifier. Using the procedure explained in the previous check item (after plugging the input cables back into the amplifier) test for output at the speaker outputs of the amplifier. Unless you enjoy test tones at high levels, it is a good idea to remove the speaker wires from the amplifier while doing this. Turn the volume up approximately half way. 5V or more should be measured at the speaker outputs. This output level can vary greatly between amplifiers but it should not be in the millivolt range with the source unit at half volume. If you are reading sufficient voltage, check your speaker connections as explained below.
Check to ensure that the speaker wires are making a good connection with the metal inside the terminal block. The speaker wire connectors are designed to accept up to 8 AWG wire. Make sure to strip the wire to allow for a sufficient connection with the metal inside the terminal block.
