About the Kicker 43DXA125.2
Power your speakers
Power your speakers
Kicker's DXA125.2 2-channel amplifier can send 30 watts RMS each to a pair of speakers from a compact chassis that'll fit into a lot of places in your vehicle. This amp delivers around three times the power of a typical factory radio, so it'll add a lot of clarity and punch to your music. You can also use the DXA125.2 in bridged mode to power a subwoofer with 125 watts RMS.
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.
Tone controls to make it sound right
The DXA125.2 features separate controls that work with a variety of different speakers or subs. A high-pass filter clears rumble from small speakers so they can play more efficiently, while a low-pass filter adjusts the frequencies going to your sub, so it'll play bass cleanly. A bass boost lets you add some extra foundation to your sound if you want.

Kicker 43DXA125.2 reviews
For kicker to manufacture an amplifier not much bigger than a wallet this little 125.2 will shock you for what it can do

Excellent Sub for 06 Jeep Wrangler. Nice and compact and pushes exactly what I need. Easy to wire and nothing short of quality as Kicker usually is.

I used this to add a sub to the factory system in my wife's new 4 Runner. The concept was to remove the base from the factory system due to the system sounding a bit muddy. The amp had all the features we needed to connect into the factory read door speaker wires. Built in crossover, base boost and high level inputs. As always, great sales and tech support from the Crutchfiled team.
Pros: Great price ' Great features
Cons: Can't think of any.

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.
DXA125.2 Output: Measured under CEA-2006 conditions the Kicker DXA125.2 is rated at 30 watts RMS x 2 channels into a 4-ohm load, 60 watts RMS x 2 channels into a 2-ohm load, and 125 watts RMS x 1 channel into 4 ohms bridged (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 DXA125.2 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 DXA125.2 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.
Input Level: The DXA125.2 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 crossover can be configured as high-pass, low-pass, or off (full range). When activated, you can adjust the crossover frequency 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.
Wiring Recommendations: Kicker recommends that the amplifier be connected to the vehicle's battery using 8 Gauge power and ground wiring. An external 40 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 PK8, CK8, and ZCK84 wiring kits for this amp. The amplifier and installation kit must be purchased from an authorized Kicker dealer.
Left Side of Amplifier: The DXA125.2 has terminal strips for connecting the power and speaker wires. For a clean, secure installation, ring terminals and/or spade connectors should be used. A flat head or Phillips head screwdriver (not supplied) is required to tighten/loosen the terminals. The amp's connections are as follows:
- GND (ground): Terminal will accept a ring terminal or spade connector up to 1/2" wide. 8 gauge ground wire is recommended.
- REM (remote turn-on): Terminal will accept a connector up to 5/16" wide. 18 gauge is recommended
- +12V (power): Terminal will accept a ring terminal or spade connector up to 1/2" wide. 8 gauge power wire is recommended.
- Speaker Outputs: Terminals accept spade connectors up to 5/16" wide. Markings are provided on the terminals for bridging the amplifier.
Right Side of Amplifier:
- RCA Inputs: one pair of RCA jacks, used for line level or speaker level inputs with KISL
