About the Kicker 43DXA500.1

Power for your sub

Kicker's DXA500.1 subwoofer amplifier can put out some great-sounding bass — the kind that grabs your attention and makes listening to music in your car more fun. And this reliable amp delivers up to 500 watts RMS from a compact chassis that'll fit into a lot of places in your vehicle.

Power for your sub

Kicker's DXA500.1 subwoofer amplifier can put out some great-sounding bass — the kind that grabs your attention and makes listening to music in your car more fun. And this reliable amp delivers up to 500 watts RMS from a compact chassis that'll fit into a lot of places in your vehicle.

Works with a factory radio

Kicker's Fail-Safe Integration Technology (FIT™) allows you to tap into your vehicle's factory speaker wiring for the amp's input signals without needing a converter. The "differential-balanced" inputs also help prevent audio interference and noise from entering the system.

Controls to help get the job done

The DXA500.1's low-pass filter adjusts the range of frequencies going to your sub so it can play bass more cleanly and efficiently, while a bass boost can add some extra foundation to the sound if you want. You can add an optional wired remote control to adjust the volume of the bass from your front seat.

Subwoofer power

Daniel from West Des Moines, IA on 5/10/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

Kicker amps rock! This is a small amp, but mighty! Very happy, perfect power match for my new subwoofer. Takes up very little room.

Pros: Compact. Powerful. Bought the "scratch and dent" discount. Don't see any scratches or dents and saved $20.

Cons: Didn't come with a manual, but can download from the site easily enough.

Great power with a small footprint!

Joe from Key Largo, FL on 7/20/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

This a has a very small footprint, runs one 12" kicker in a 1.4cuft box under the seat of my 2016 crew cab Silverado. I was impressed with the output of the sub and amp. I'm am using an audio control lc2i with it to get the high level outputs off the rear door speakers. Also installed dynamat in all four doors, rear cab floor and back cab wall. I was able to do this install with not one hole made into this truck. Install came out perfect. Thanks crutchfield and kicker!

Pros: Small, efficient, easy to install almost anywhere and is not getting hot

Cons: None

Features

CEA-2006 Compliant: CEA-2006 is a system of testing and measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for determining an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured over the full frequency range of the amp with 1% or less Total Harmonic Distortion plus noise (THD+N). Signal-to-Noise ratio is measured in weighted absolute decibels at a reference of 1 watt. CEA-2006 allows consumers to compare car amplifiers and receivers on equal footing.

DXA500.1 Output: Measured under CEA-2006 conditions the Kicker DXA500.1 is rated at 250 watts RMS x 1 channel into a 4-ohm load and 500 watts RMS x 1 channel into a 2-ohm load (measured using a 14.4 volt power supply).

Auto Turn-On: There are two ways to automatically turn on the amplifier. Most aftermarket car stereo head units will have a remote turn-on lead, which can be extended to the amplifier location and connected to the amp's Remote terminal. If connecting the amplifier to a factory stereo, or a head unit without a remote turn-on lead, the amp can automatically turn on using the DC Offset mode. The amp detects a 6-volt DC surge on the signal inputs and turns the amplifier on. There is no switch on the amp to select the Turn-On method.

Protection Circuitry: The DXA500.1 has protection circuitry that will turn the amp off in the event of overheating, over voltage (over 16 volt input), under voltage (under 10 volt input), and short circuit (speaker output). If the Protection LED on the right side of the amp illuminates red, the protection circuit has engaged and the amp will not play until the problem is resolved.

Dual Input Sensitivity: The DXA500.1 can receive low- or high-level signals from your car stereo source unit at the amplifier's left and right RCA inputs. The low-level signal can be sent from the source unit's RCA line-level outputs. In this case, the Input Sensitivity switch on the amp should be set to "LO". A high-level signal can come from the source unit's speaker outputs, and connected to the amplifier using the Kicker KISL adapters. The Input Level switch should be set to "HI".

Fail-Safe Integration Technology (FIT): FIT utilizes isolated differential inputs, rejecting noise and electrical interference for the quietest operation possible. FIT also allows Kicker amps to accept output from nearly any factory or aftermarket head unit.

Controls

Input Level: The DXA500.1 has a two position (in/out) switch to set the input level type. It can be pressed in for High (for speaker level) or set to out for Low (for line level).

Gain: The input gain is continuously variable, labeled 0 to 11. The gain range is governed by the input level switch: 250mV to 10V for speaker level (HI) and 125mV to 5V for line level (LO). A small screwdriver is needed to adjust the gain.

Crossover Frequency: The internal low pass crossover is always active (it cannot be bypassed). The crossover point is continuously variable between 50 and 200 Hz. The slope is 12 dB/octave. A small screwdriver is needed to adjust the crossover frequency.

KickEQ Bass Boost: The KickEQ bass boost circuit provides a signal boost centered at 40 Hz. The bass boost is continuously variable between 0 and 12dB. A small screwdriver is needed to adjust the amount of bass boost.

Subsonic Filter: Frequencies that cannot be reproduced by the subwoofer do not become sound, but unnecessary oscillations causing distortion. These frequencies also waste amplifier power and can damage speakers. The subsonic filter removes inaudible frequencies to improve the performance of the speakers by eliminating this harmful distortion. The 24 dB/octave subsonic filter's crossover point is 25 Hz.

Installation

Wiring Recommendations: Kicker recommends that the amplifier be connected to the vehicle's battery using 4 Gauge power and ground wiring. An external 80 amp fuse should be installed on the power wire within 18" of the battery. There are no fuses included or built into the amplifier.

Kicker Extended Warranty Offer: Kicker will extend the amp's standard warranty by an additional year (for a total warranty of three years) when it is installed with a qualifying Kicker amplifier installation kit. Kicker recommends the PK4, CK4, and ZCK44 wiring kits for this amp. The amplifier and installation kit must be purchased from an authorized Kicker dealer.

Connections

Left Side of Amplifier: The DXA500.1 has set screw terminals for connecting the power wires and terminal strips for the speaker wires. The set screw terminals can be tightened or loosened with the supplied 3mm Allen wrench. Spade connectors should be used on the speaker wires for a clean and secure installation. A flat head or Phillips head screwdriver (not supplied) is required to tighten/loosen the screw terminals. The amp's connections are as follows:

  • GND (ground): Set screw terminal will accept up to 4 gauge bare ground wire. 4 gauge wire is recommended.
  • REM (remote turn-on): Set screw terminal will accept up to 8 gauge wire. 18 gauge is recommended
  • +12V (power): Set screw terminal will accept up to 4 gauge bare power wire. 4 gauge wire is recommended.
  • Speaker Outputs: Terminals accept spade connectors up to 5/16" wide. There are terminals for two subwoofers, internally wired in parallel.

Right Side of Amplifier:

  • RCA Inputs: one pair of RCA jacks, used for line level or speaker level inputs with KISL
  • RCA Outputs: one pair of RCA outputs; useful for adding another amp
  • Remote Bass: 3.5mm jack (mini-jack) for use with the optional CXARC remote bass level control
