Mounting the Amplifier

The JBL P-7520, P-7540 or P-2510 can be mounted in virtually any location inside the vehicle. However, make sure to keep the amplifier away from heater vents or ducts.

1.At the chosen site, use the amplifier as a mounting template and mark the locations of the four mounting holes.

2.Drill a small pilot hole at each marked location.

3.Mount the amplifier and securely tighten the mounting screws.

Wiring the Power Connections

Refer to diagrams on pages 3 and 4 for connector locations.

1.For power, remote and speaker wires, strip 1⁄4" off one end of each jacket to reveal bare wire for insertion into the barrier strip connectors.

2.Locate the 3-connection barrier strip labeled +Batt, Rem and Gnd. Connect a black wire (at least 10G) to the Gnd ter- minal and connect the other end to the nearest bare-metal chassis component. Then, connect a red wire (at least 10G) from the vehicle’s +12-volt battery terminal to the +Batt terminal on the barrier strip. Finally, connect a blue wire (16G) to the Rem terminal on the barrier strip and connect the other end to the Rem output of the source unit. If you are using speaker-level inputs and speaker-level outputs from the source, disregard the previous instruc- tion regarding the Rem terminal.

Wiring the Speaker Output Connections

1.Connect the speakers, observing prop- er polarity, to the speaker-output barri- er strip on the amplifier using at least

16G high-quality speaker wire. (Note: The total impedance of the speakers connected to the outputs when the amp is driven in stereo must be at least 2 ohms. Because the P-2510 is a single-channel amplifier, the speaker connections on the barrier strip are wired in parallel inside the amp. The total impedance of the speakers con- nected to the P-2510 must be at least 2 ohms.)

2.If you are bridging the amplifier, con- nect the speaker wires to the termi- nals marked “bridge,” observing prop- er polarity. (Note: The total impedance of the speaker system to be connected to the amplifier must be at least 4 ohms in bridge mode.)

3.If you are running either the P-7520 or the P-7540 in tri-mode (stereo and mono simultaneously to one or two pairs of satellite speakers and a sub- woofer), refer to the chart above to determine the capacitor and inductor values you’ll need to route bass sig- nals to the woofer, and midrange and high frequencies to the satellite speak- ers. These passive-crossover compo- nents will also ensure that the imped- ance of the speaker system doesn’t drop below 2 ohms. The P-2510 should be used to drive woofers only as its bandwidth is limited to 20Hz – 320Hz.

Wiring the Input Connections

1.If you are using conventional RCA input connections and a source unit with output voltage less than 4V, sim- ply plug the RCA plugs into the RCA jacks on the amplifier.
