to read this manual before operating or installing your ampliﬁer. This manual describes general installation guidelines and

TROUBLESHOOTING ................................................................................................................................................6

• Using the ampliﬁer as a template, mark the locations of the

holes on the mounting surface.

• Drill pilot holes in the mounting surface.

• Attach the ampliﬁer to the mounting surface with the included

sheet metal screws and washers.

Power and Ground Connections

• Power: Connect the yellow power wire to the positive +12V

terminal of the vehicle’s battery. Make sure the 15A fuse and

fuse holder are within 18" (457mm) of the battery.

• Ground: Connect the black wire to the negative terminal GND

of the vehicle’s battery, or to the vehicle’s chassis near the

battery with a screw. If possible, remove any paint from NOTE:

the chassis for best contact. It is recommended to use a star

washer below the ring connector for a secure connection.

• Remote-In: Connect the red remote turn-on wire to the

“Remote Out” lead of the source unit, if using low-level signal

inputs with an aftermarket stereo. If you are using NOTE:

high-level signal inputs (your vehicle’s speaker wires), you can

choose to have the 12-volt DC offset feature turn the ampliﬁer

on when you turn on the vehicle power, or the audio-sensing

feature turn on the ampliﬁer when it detects audio signal. In

either case, you will not have to connect the remote turn-on

wire and can tape or cap it off to prevent the introduction of

noise.

• Remote-Out: Connect the blue remote-out wire to external

devices that require 12V turn-on after the Inﬁnity INFDSP4425.

This connection will allow turn-on of 12V devices after the

ampliﬁer wakes from turn-on by 12V remote-in, DC offset or

audio signal sensing input.

• When all connections are made, plug the harness into the

ampliﬁer.

Power/Protect indicators

The power light will illuminate in green when the ampliﬁer is getting

power and playing. The protect light will illuminate in red if the amp

enters protect mode in the event of conditions such as over/under

voltage, ampliﬁer output circuit failure, or excessive heat.

PRODUCT DESCRIPTION

The Inﬁnity DSP Ampliﬁer is an audio processor for ﬁne-tuning of

aftermarket audio systems. It is a self-contained audio system with

4-channel powered audio outputs and 2-channel preamp outputs,

an easy-to-use tuning interface a novice can understand, and

detailed tuning capabilities to satisfy even experienced installers.

With a USB connection to access the tuning interface using a

Windows PC, you can control fully variable crossovers, selectable

0-to-48 dB slopes, time delay, 31-band parametric or graphic EQ

adjustment, assignable input-to-output mixer with input channel

summing, channel gain, master volume control, clipping indicator

to ensure the audio output is not distorted, and ability to save up

to 10 presets.

INSTALLATION AND WIRING

IMPORTANT: Disconnect the vehicle s negative (–) battery 

terminal before beginning the installation.

• Wear protective eyewear when using tools.

• Choose a safe mounting location. Check clearances on both

sides of the location. Be sure that screws will not puncture

brake or fuel lines or wiring harnesses, and that wire routing will

not interfere with vehicle operation. Use caution when drilling

or cutting.

• When making electrical connections, make sure they are

secure and properly insulated.

• Do not mount the ampliﬁer with the heat sink facing downward,

as this interferes with cooling.
