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) 443-1100 during business hours.
PROTECT YOUR HEARING!
We value you as a long-term customer. 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 other high-power amplifiers 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.

TYPICAL INSTALLATION SEQUENCE
The following represents the sequence for a typical amplifier installation, using an aftermarket source unit or OEM Interface processor (like the CleanSweep® CL441dsp).
Additional steps and different procedures may be required in some applications. If you have

1) %JTDPOOFDU UIF OFHBUJWF CBUUFSZ QPTU connection and secure the disconnected cable to prevent accidental re-connection during installation. This step is not optional!
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-on wire 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-on wire 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-check that 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.
