Kicker's DXA250.2 2-channel amplifier will deliver 30 watts RMS each to a pair of speakers from a very compact chassis that'll fit into a lot of places in your vehicle. This amp delivers around three times the power of a basic factory system, so you'll add a lot of clarity and punch to your sound. You can also use the DXA125.2 in bridged, 1-channel mode to power a subwoofer with 125 watts RMS..
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.
DXA125.2 input and control panel
The DXA125.2 features separate controls that work with a variety of different speakers or subs. A high-pass filter clears out rumble from small speakers so they can play more efficiently, while a low-pass filter adjusts the bass frequencies going to your sub, so it'll play cleanly. The bass boost can add some extra foundation to the sound if you want.
Average Customer Review(s):
Very good power for my twittters and speakers
Nice material. Sturdy and lite to install.
Pros: Price and lite.
Great amp to push my 4 1/2 Kenwood speakers. This Kicker amp is the perfect suggestion that was given to me.
Awesome sound and bass boost. Plug and play installation. Recommend viewing YouTube amp installation video (s) if you plan on installing DIY.
I am using 2 of this amps, 2 kicker 6x9 and 1 kicker 10" sub on a boom box, and of course a Bluetooth receiver and an eq. A marine battery provides the juice to this setup and runs for hours. This is a great way to listen to your iphone pretty loud and clear.
Pros: Great Sound, more than enough power and low distortion.
Cons: none so far
Good amp small size big power
Pros: Reasonably priced

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. Measured under CEA-2006 conditions the Kicker DXA125.2 is rated at 30 watts RMS x 2 channels into a 4-ohm load and the signal to noise ratio is >95 dB. Additional specs listed in the manual (but not listed as CEA-2006 compliant) include 60 watts RMS x 2 channel into a 2-ohm load (measured using a 14.4 volt power supply with no more than 1% THD+N) and 95 dB signal-to-noise ratio (measured at the rated power output).
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.
Stereo-and-Mono-Simultaneously (SAMS): The amp has the capability of powering a pair of full-range speakers and a mono subwoofer from one pair of channels. Using passive crossovers, you can high-pass the signals to the full-range speakers and to low-pass the signals to the subwoofers. The SAMS wiring diagram can be found in the Owner's Manual.
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 crossover can be set for low-pass (LO), high-pass (HI), or full-range operation (OFF). The crossover frequency range is continuously variable between 50 Hz and 200 Hz. The crossover slope is 12 dB per octave A small screwdriver is needed to set the crossover cutoff 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, or ZCK84 wiring kit for this amp. The amplifier and installation kit must be purchased from an authorized Kicker dealer.

Lots of power.[ James May 01, 2016 ]
I was looking for a amplifier for speakers that I had purchased from Crutchfield.[ Richard Apr 05, 2016 ]
Decently priced[ Austin Apr 02, 2016 ]
I only run 2 subs does it have 2 or 4 channel output ? [ CHARLES Feb 13, 2017 ]
Usually Tweeters use a capacitor to filter out lower frequencies. I have had similar setups with other amplifiers without any issues. Personally I do not see you having any issues adding tweeters in parallel to the 5.25 speakers.[ HECTOR Sep 29, 2016 ]
