Ultimate Music Customization

The Kicker Front Row makes music from a vehicle’s system sound better than it ever has, with the listener experiencing staging, imaging and bass response actually like the artist intended. Front Row utilizes a familiar, simple analog-based control system, but underneath the dials lays a powerful micro-controller with all signal manipulation done in digital domain. Most of the Front Row’s dynamic features can be adjusted from the driver’s seat using the convenient remote. It is a must-have solution for controlling audio signal.

Clear Sound at High Volume

Clear Sound at High Volume

The subwoofer section includes a variable subsonic filter that preserves bass impact by protecting the woofers and focusing bass-amplifier power on what should be heard. Additionally, each section incorporates a Clip Limiter, a fast-acting compressor that monitors input signal and prevents clipping and distortion while preserving overall output signal. The result is the clearest sound at high volumes.

Full of KICKER Tech

Most of the Front Row’s dynamic features can be adjusted from the driver’s seat using the convenient remote. Speaker Time Alignment provides complete soundstage height, width and control, putting a realistic stage with a focused center image where it should be – on the vehicle’s dash and not the floor. Simulated 5.1 Surround Sound mimics the “live” rear fill one experiences in a stadium or concert.

Max Customization

The Front Row provides six channels of 32-step, fully variable digital crossovers with selectable slopes and minimal phase shift for maximum system-design flexibility. Input-gain and output-level controls for each section (front/rear/subwoofer), along with input clip indicators, enable easy level matching for a clean, distortion-free setup.

Precise Control

The Front Row utilizes a familiar, analog-based control system, but underneath the dials lays a powerful micro-controller with all signal manipulation done in digital domain (28-/56-bit, double-precision DSP w/ 24-bit AD/DA converters) - it is a must-have solution for controlling audio signal.

General Specifications

Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Low-pass (LP)
High-pass (HP)
Full (AP)
Built-in Bass Reconstruction
Bass reconstructors, or bass enhancers, improve low frequency reproduction in a car audio system with at least one subwoofer. These bass expander products will help your subs produce accurate bass thumps.
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Total Number of Inputs
This is the total number of input connections that go into the unit.
Total Number of Outputs
This is the total number of output connections that the unit will produce.
Equalizer Frequencies
The frequency range that allows control of the center frequency of each equalization band.
10 - 22000 Hz
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
110 dB

Excellent Processor & Crossover

November 20, 2013

I bought this processor primarily for it's time alignment feature. I had this feature in an Alpine HU I had years ago. Why more manufactures don't add this to their products I don 't know. A little tip on setting the Stage control. The manual suggests using music with a "strong female vocal blah blah blah" to adjust the "Stage". Don't waste your time. I use a mono Beatles CD to set the time alignment. With a mono signal source the image should be the center of your dash. Fade your HU to it's front speakers only and dial in the amount of delay to the left channel until the sound stage centers itself on your dash. Once you've done that, do the same for the rear speakers. I personally don't care much for the "Surround" and "SHOC" features and don't really use them.

The FR's crossover on the other hand is excellent. I have my front and rear speakers hi-passed around 80Hz @ 24dB/octave. The sub-woofers are lo-passed at the same frequency with a 48dB/octave slope. This does an outstanding job of removing any mid-bass from the subs that might give away the fact that they're located in the back. For me this allows the subs and front speakers (the rear speakers are set low so they don't detract from the up front imaging I prefer) to blend together seamlessly. I haven't had a chance to fiddle with the sub's phase control. It's currently set to zero and I haven't felt the need to tweak it any.

The only feature that the FR lacks IMO is a bypass setting on the remote. I'm usually in the truck alone so I have the Stage set up for optimum listening for when I'm the only listener. This makes for a bit of an odd listening experience for when there is a passenger riding along with me. A quick bypass button for these instances would be a nice addition over dialing out the time alignment for the front & rear speakers individually every time there is a passenger with me and then having to dial it back in again for when I'm alone.

I only gave the Durability 3 stars because the FR is NEW and I'm reviewing it NOW. Value gets 4 stars because the FR is a bit on the pricey side.

Works as advertised

September 15, 2015

This unit is a great addition to my sound system. Works great as a three way crossover! I was able to fine tune 8" mid bass speakers for cleaner sound. Other features work great too. Would not hesitate to buy again!

Excellent Product!

March 13, 2013

I must be the first in Jamaica to buy this. I bought this product a few days ago. Have it installed in my corolla ae110. Have it on two kicker cvr12's and two eminence beta 8a's. Upon installation I was able to hear the difference in sq coming from the speakers and a more powerful sound system. At first I was using the boss bx45 and had to turn my gains all the way up. Now my gains are just below half and is much cleaner and louder!... Excellent product! The remote works just as advertised and the clip limiter is an excellent feature!!
