Installation

Mounting

When selecting a location to mount your Kicker amplifier be

sure it is structurally sound and that there are no items behind

the area that could be damaged by the screws. Check for wiring

harnesses, brake lines, fuel lines, gas tanks, etc.

All amplifiers generate heat under normal operation. Be sure to

choose a location that allows adequate ventilation for the

amplifier. Also consider that the air temperature inside an

automobile’s trunk can reach upwards of 140 degrees

fahrenheit (60° celsius). An amplifier mounted here may require

additional cooling needs such as fans or venting to allow cool

operation. If possible, mounting the amp in the passenger

compartment will allow cooler operation.

Remember that the controls on top of the amp will need to be

accessible for adjustment later. Keep this in mind as you choose

your amplifiers mounting location.

Now that you are ready to mount your amplifier, use the

supplied 3mm allen wrench to remove the amplifier EndKaps.

This will give you access to the mounting holes in the

amplifier and all wiring connections.

NOTE: Objects in the manual are larger than they appear!

Pictures and diagrams of the massive KX2500.1 in this manual

are not to scale...this was done to prevent having a manual the

size of your average wakeboard.

With the shroud removed, drill 4 holes using a 7/64” (2.75 mm)

drill bit and use the supplied #8 screws to mount the amplifier.

Installation

Wiring

Signal can be input into the amplifier using either the low level

RCA input connections or the high level speaker level

connections. Using the low level RCA connections is the

preferred method. Use the high level inputs only if your head unit

does not have low level RCA type outputs. Connecting to the

amp with either input will provide a low level signal at the output

(PAST) jacks.

BASS

The use of twisted pair interconnects is recommended for all

installations to minimize noise. When routing these cables

through the automobile, try to keep them away from factory

wiring harnesses and other power wiring. If you need to cross

any of this wiring do so at a 90 degree angle to reduce the

possibility for noise problems.

When working with power connections it is always

recommended that you disconnect the battery to prevent

accidents.

The ground should be connected to the amplifier first before

making any of the other connections. This wire should be as

short as possible (36 inches or less) and connected to a paint

and corrosion free solid metal area of the car’s chassis.

Use the same gauge wire as recommended for the amplifier’s

power connection to the battery. Adding an additional ground

wire between the car battery’s negative post and the car chassis

of this same gauge (or larger) is highly recommended. Adding or

upgrading the ground from the case of the alternator to the car

chassis is also recommended.

If you ever need to remove the amp from the vehicle after it

has been installed, the ground wire should be the last wire

disconnected from the amplifier. Just the opposite as when you

installed it.

The supplied ANL fuse holder and fuse must be installed within

18 inches of the battery to protect the power wire feeding your

amplifier.

The Remote Turn-On lead gets connected to your source unit’s

power antenna lead or another switched + 12 volt source in your

vehicle.

BIG AMP AHEAD

Just in case you missed it at the time of purchase, this is a BIG amplifier that will create BIG power. For an amplifier to

produce 2500 watts of output power it requires a solid electrical system feeding it and a solid delivery system to your speakers. What

this means is you have to use the appropriate wire and accessories with this amplifier to insure optimum performance and durability.

We recommend using Genuine Kicker Installation Accessories. Visit your local dealer or visit www.Kicker.com to learn more.

Kicker highly recommends the following:

 An alternator with a minimum 140 amp output capacity.

 At least one extra battery located close to the amplifier.

 1/0 gauge power and ground feeds to the extra battery.

 Proper fusing as per diagram below.

 Short as possible power and ground feeds to the amplifier.

 Aminimum of 12 gauge speaker wire from amp to speakers. Up to 8 Gauge can be used and is recommended.

 Earplugs.

System Diagrams

The following diagrams shows the most common configurations for your Kicker KX2500.1 series amplifier.

MONO CHANNEL OPERATION

The KX2500.1 amplifier is capable of operating into a minimum impedance of 2 ohms (Ω). If you are using a single voice coil

woofer be sure the impedance of the voice coil is equal to or greater than 2Ω. If using dual voice coil subwoofer or driving

multiple subwoofers, be sure the net impedance presented to the amplifier is at least 2Ωor greater.

TWO KX2500.1 AMPLIFIERS & ONE DVC SUBWOOFER

This diagram shows how to power a single Dual Voice Coil (DVC) subwoofer using two KX2500.1 amplifiers. For maximum power

output from your KX2500.1 to the subwoofer each voice coil should be 2Ωimpedance. Do not connect to voice coils with an

impedance lower than 2Ω!

Be sure to properly power and ground each amplifier according to the minimum specifications shown on page 6 to insure proper

operation and maximum power output.

NOTE: The gain setting/output level on both amplifiers must be matched for proper operation. If the output level of both amplifiers is

not matched this will result in poor performance and possible damage to your subwoofer.

To properly set the levels you will need a test CD containing a 60 Hz test tone and a digital volt meter. Play the 60 Hz tone through

your CD player set at a low to moderate volume level. Next, measure the AC voltage output across each amplifier’s positive (+) and

negative (-) speaker output terminals. Turn the gain down on the amplifier which reads higher until it matches the other amplifier.
