OWNER’S MANUAL

monoblock subwoofer amplifier

Thank you for purchasing a JL Audio amplifier for your automotive sound system.

Your amplifier has been designed and manufactured to exacting standards in order to ensure years of musical enjoyment in your vehicle. For maximum performance and extended warranty

coverage, we highly recommend that you have your new amplifier installed by an authorized JL Audio dealer. Your authorized

dealer has the training, expertise and installation equipment to ensure optimum performance from this product. Should you

decide to install the amplifier yourself, please take the time to read this manual thoroughly so as to familiarize yourself with its installation requirements and setup procedures.

If you have any questions regarding the instructions in this manual or any aspect of your amplifier’s operation, please contact your authorized JL Audio dealer for assistance. If you need further assistance,

please call the JL Audio Technical Support Department at (954) 443-1100during business hours.

PROTECT YOUR HEARING!

We value you as a long-termcustomer. For that reason, we urge you to practice restraint in the operation of this product so as not to damage your hearing and that of others in your vehicle. Studies have shown that continuous exposure to high sound pressure levels can lead to permanent (irreparable) hearing loss. This and all otherhigh-poweramplifiers are capable of producing such high sound pressure levels when connected to a speaker system. Please limit your continuous exposure to high volume levels.

While driving, operate your audio system in a manner that still allows you to hear necessary noises to operate your vehicle safely (horns, sirens, etc.).

SERIAL NUMBER

In the event that your amplifier requires service or is ever stolen, you will need to have a record of the product’s serial number. Please take the time to enter that number in the space provided below. The serial number can be found on the bottom panel of the amplifier and on the amplifier packaging.

2)Run power wire (minimum 4 AWG) from the battery location to the amplifier mounting location, taking care to

route it in such a way that it will not be damaged and will not interfere with vehicle operation. Use 2 AWG or 1/0 AWG power wire if additional amplifiers are being installed with the 1000/1v2.

3)Connect power wire to the positive battery post. Fuse the wire with an appropriate fuse block (and connectors) within 18 inches (45 cm) wire length of the positive battery post. This fuse is essential to protect the

4)Run signal cables (RCA cables) and remote turn-onwire from the source unit to the amplifier mounting location.

5)Run speaker wire from the speaker systems to the amplifier mounting location.

6)Find a good, solid metal grounding point close to the amplifier and connect the negative power wire to it using appropriate hardware. Use minimum 4 AWG power wire, no longer than 36 inches (90 cm) from the amplifier to the ground connection point. In some vehicles, it may be necessary to upgrade the battery ground wire. (See page 5 for important notice).

7)Securely mount the amplifier using appropriate hardware.

8)Connect the positive and negative power wires to the amplifier. A fuse near the amplifier is not necessary.

9)Connect the remote turn-onwire to the amplifier.

10)Connect the RCA input cables to the amplifier.

11)Connect the speaker wires to the amplifier.

12)Carefully review the amplifier’s control settings to make sure that they are set according to the needs of the system.

13)Install power wire fuse (100A for a

single 1000/1v2) and reconnect the negative battery post terminal.

14)Turn on the source unit at a low level to double-checkthat the amplifier is

configured correctly. Resist the temptation to crank it up until you have verified the control settings.

15)Make necessary adjustments to the input sensitivity controls to obtain the right overall output and the desired balance in the system. See Appendix A (page 14) for the recommended input sensitivity setting method.

16)Enjoy the fruits of your labor with your favorite music.

Speaker loads below 1.5Ω 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 i+w QPTJUJWF DPOOFDUJPOT BOE UXPiwOFHBUJWF 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.

The 1000/1v2’s speaker connectors are designed to accept 12 AWG – 8 AWG wire.

To connect the speaker wires to the amplifier, first back out the set screws on the top of the amplifier, using the supplied 2.5 mm hex wrench. Strip 1/2 inch (12 mm) of insulation from each wire and insert the bare wire end into the receptacles on the front panel of the amplifier, seating them firmly so that no bare

wire is exposed. While holding each wire in place, tighten each set screw firmly, taking care not to strip the head of the screw and making sure that the wire is firmly gripped by the set screw.

STATUS INDICATOR LIGHTS / PROTECTION CIRCUITRY

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 selfprotection mode, which reduces the power output of the amplifier. The red light will shut off and the amplifier will return to normal, full-poweroperating mode if the heat sink temperature drops back to a safe level.

3)iLow Ωw(Amber): lights to indicate that the impedance of the speaker load connected to the amplifier is lower than the optimum

impedance load range for the amplifier. When this light is on, a protection circuit engages and reduces the power output of the amplifier. The amber indicator will also light when a short-circuitis detected in the speaker wiring (this can be a short between the positive and negative speaker wires or between either speaker wire and the vehicle chassis).

4) “Low V” (Blue): lights to indicate any dip in supply voltage below 8 volts. The

If you are unsure as to the cause of the problem, please consult your JL Audio dealer or a qualified automotive electrical specialist.

Keep in mind that any large amplifier, like the 1000/1, places a very heavy demand on a vehicle’s charging system when operated at its limits.

Vehicles with weak charging systems may need to be serviced and/or upgraded to provide ample current to a system including a 1000/1.

If this is happening in your system, have your charging system inspected to make sure it is working properly.

Intelligent Power Supply (R.I.P.S.) allow delivery of their rated power when connected to any load impedance from 1.5 - 4Ω 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.

The Nine-StepProcedure

1) %JTDPOOFDU UIF TQFBLFS T GSPN UIF amplifier’s speaker output connectors.

2)Turn off all processing (bass/treble, loudness, EQ, etc.) on the source unit, processors (if used) and amplifier. Set fader control to center position and subwoofer level control to 3/4 of maximum (if used to feed the 1000/1v2).

3)Switch the iInput Voltagew switch to iLoww and turn the iInput Sens.w control all the way down.

4)Set the source unit volume to 3/4 of full volume. This will allow for reasonable gain overlap with moderate clipping at full volume.

5)Using the chart on this page, determine the target voltage for input sensitivity adjustment according to the nominal impedance of the speaker system connected to the amplifier outputs.

6)Verify that you have disconnected the speakers before proceeding. Play a track with an appropriate sine wave (within the frequency range to be amplified by the 1000/1v2) at 3/4 source unit volume.

7)Connect the AC voltmeter to the speaker output connectors of the amplifier. If the channel

pair is operating in stereo, it is only necessary to measure one channel. If bridged, make sure you test the voltage at the correct connectors (L+ and R–).

8)Increase the iInput Sens.w control until the target voltage is observed with the voltmeter.

9)Once you have adjusted the 1000/1v2 to its maximum low-distortionoutput level,

reconnect the speaker(s). The iInput Sens.w control can now be adjusted downward if the amplifier requires attenuation to achieve the desired system balance.

!I M P O RTA N T

Do not increase any “Input Sens.” setting for any amplifier channel or channel pair in the system beyond the maximum level established during this procedure. Doing so will result in audible distortion and possible speaker damage.

APPENDIX D:

Master/Slave Configurations

With the flexible on-boardcrossovers and processing incorporated into the 1000/1v2, it is possible to connect multiple 1000/1v2’s in a

i.BTUFS 4MBWFw DPOGJHVSBUJPO XJUI FBDI BNQMJGJFS driving its own speaker system but controlled by the processing and filtering of only one amplifier. This is very useful when driving multiple subwoofers with multiple amplifiers.

To create a Master/Slave configuration, first

EFUFSNJOF XIJDI BNQMJGJFS XJMM CF UIF i.BTUFSw amplifier and connect the main input signal to that amplifier (from the source unit or from an

PVUCPBSE QSPDFTTPS 5IJT BNQMJGJFST iAmp LP Filterw TFDUJPO BOE iAdvanced Bass Controlw GFBUVSFT XJMM QSPDFTT UIF TJHOBM GPS UIF i4MBWFw amplifier or amplifiers.

MASTER:

The Master amplifier’s “Advanced Bass Control”section is active and affects all three amplifiers equally.

Here is the procedure for implementing a i.BTUFS 4MBWFw DPOGJHVSBUJPO

3)The input sensitivity of the two amplifiers needs to be adjusted independently. To properly calibrate the amplifiers for maximum, identical, clean output, please refer to Appendix A (page 14). After using this procedure, you can then adjust the level of the amplifiers by adjusting the input sensitivities

downward, if the amplifiers require attenuation to achieve the desired system balance. If the input sensitivities are adjusted, the amplifiers must be recalibrated to ensure identical power output levels.
