    Great product

    Matt from Stillwater, MN on 3/31/2014

    Upgraded from an old kenwood deck and was very pleased with the difference in audio quality when using a high end sub and even with my stock speakers. JVC headunits are probably the best bang for your $ IMO

    Crutchfield Customer Review (What's this?)

    Overall I was surprised with the quality of this stereo. Very easy to hook up (especially with the adapter harness), the sound quality was actually a lot better than I expected to get for the price. It is fairly easy to use, although some aspects of the menu require a lot of key presses. Construction wise, it feels sturdy.

    Pros: Amazing sound, easy installation, nice look.

    Cons: Menu takes some getting used to as most setting are buried.

    JVC Arsenal KD-A645 Review

    Anonymous from SW Montana on 9/21/2013

    Crutchfield Customer Review (What's this?)

    A great head unit that delivers greatly improved sound over factory unit, So good that now I have to upgrade speakers to enjoy the full benefit! Install was fairly easy and took about two hours start to finish. Someone with experience could cut that time in half. Now I can finally enjoy Pandora and Slacker without hassles.

    Pros: Great value! Excellent Crutchfield support-they supply everything you need to do it right the first time. Unit sound terrific!!

    Cons: It works, sounds great and is easy to operate....can't really come up with any "cons"

    Crutchfield Customer Review (What's this?)

    CD player skips

    Mike from Richmond on 7/19/2013

    Crutchfield Customer Review (What's this?)

    Radio installed easily and looked great. Unfortunately the CD player would't play cd's without skipping. Home mades and Studio discs both would skip randomly during playback. Had to pull it out and send it back. Bought a Sony instead. All the stereos these days look alike don't they?

    Pros: Easy to install and operate

    Cons: CD player was either defective ( i hope ). Resulted in the return of the radio.

    The jvc arsenal radio and face kit is pretty cool. It's the first item I ever purchased from crutchfield, and I must say that I am very impressed.

    Crutchfield Customer Review (What's this?)

    JVC? Who would have guessed? The sound quality of the internal amp can push the volume without distortion and very clear, while every feature laid out and in logical order. I returned a Kenwood due to sound quality and glad I got the JVC. The Kenwood was slow to update channels and slow to change XM stations quickly or cycle through channels. The JVC is not and very fast and responsive.

    Pros: XM Tuner as easy as plugging in...Iphone works great via cable and charges phone too. Sound quality is very good.

    Cons: Remote lacks features and not made for American sized hands.....too small and can't control sub via remote like Kenwood could. you cannot use remote to change Itunes playlist not good JVC.

    Audio Section

    24 Bit D/A Converter: The JVC Arsenal KD-A645 utilizes a 24-bit digital to analog converter for superior sound quality.

    MOSFET Amplifier: The KD-A645 is equipped with a MOSFET amplifier. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise. More power means louder and cleaner music at higher volumes because you're not pushing the limits of the amplification circuit.

    CEA2006 Compliant: The power specifications for the KD-A645 are compliant with the CEA2006 Mobile Amplifier Power Testing and Measurement standards from the Consumer Electronics Association (CEA). These standards were developed as a way to equitably compare power specs from model to model and between manufacturers. The power output specs for the KD-A645 are as follows:

    • CEA2006 Specs: 20 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
    • Maximum Power Output: 50 watts x 4 channels (200 total watts)

    Amplifier Gain Control: When you are using the KD-A645 with factory speakers (or those rated to less than 50 watts peak), the Amplifier Gain Control can limit the amount of power being sent to those speakers. When the Amp Gain Control is set to "low," the volume control ranges from 0 (minimum) to 30 (maximum). When using speakers rated higher than 50 watts peak, you can set the Amp Gain Control to "high," and the volume control will range from 0 to 50.

    2.5V/4CH Preamp Output: The KD-A645 is equipped with two pair of 2.5V preamp outputs (Front, Rear/SW). You can set the Rear/SW preamp outputs for connecting a pair of full-range rear speakers (through an external amplifier) or for connecting a subwoofer (through an external amplifier). When set for rear speakers, the rear outputs operate with the unit's fader control. When set for subwoofer, the outputs are non-fading.

    Subwoofer Controls: When the unit's Rear/SW preamp output is set to Subwoofer, you can set the cutoff frequency of the low-pass filter at 55Hz, 85Hz, or 120Hz. You can adjust the head unit's subwoofer level between -8 and +8 (separate from the main volume level).

    Pro EQ: The KD-A645 is equipped with JVC's Pro EQ. The integrated equalizer offers 7 preset sound modes (Flat, Natural, Dynamic, Vocal Boost, Bass Boost, & User) suitable for the music genre of your choice. The User mode allows you to manually adjust the head unit's 3-band parametric EQ (Frequency, Level, and Q-Factor).

    Pro EQ
    Frequency Level Q
    Bass 60, 80, 100, 200 Hz +/- 12 dB (-6 to +6) 1.0, 1.25, 1.5, 2.0
    Midrange 0.5, 1.0, 1.5, 2.5 kHz +/- 12 dB (-6 to +6) 0.75, 1.0, 1.25
    Treble 10.0, 12.5, 15.0, 17.5 kHz +/- 12 dB (-6 to +6) Fixed
    Note: You can store Pro EQ bass, middle and treble tone settings for each source (CD, AM/FM, Aux, USB, iPod, Bluetooth, and Pandora).

    Bass Boost: The unit's Bass Boost enhances low bass frequencies.

    Loud (Loudness): This feature boosts low and high frequencies to produce a well-balanced sound at a low volume level. You can set this feature to High, Low, or Off.

    Volume Adjust: The input level of each source (other than FM) is adjustable relative to the FM radio volume, so there isn't a significant volume difference when changing sources. Each source is individually adjustable from -5 to +5.

    Key Beep: The in-dash head unit provides an audible beep to confirm button operation. This function can be turned On or Off.

    Display Features

    Detachable Face: The JVC Arsenal KD-A645 features a detachable face to deter theft. No face-case is provided. An optional soft face case (142DFC1X, sold separately) can be purchased for this unit. A face-fixing screw is supplied for making the face non-detachable, if desired.

    Variable Color LCD & Key Illumination: The JVC Arsenal KD-A645 features 29 color presets for the LCD and button illumination. You can choose one of these color presets or select the ColorFlow mode which scrolls through all 29 color presets. Additionally, there is a User preset, allowing you to individually adjust the intensity of Red, Green, and Blue from 0 to 31; resulting in approximately 30,000 custom color options. The chosen color preset or custom color can be applied to the display panel and the backlighting for all the buttons except the eject button (it remains red). You can choose to use the same color for the LCD display and button illumination, or use a separate color for each one. You can also select a different color for daytime and nighttime in regards to the unit's LCD and button illumination.

    Brightness: The unit offers an adjustable display and button illumination brightness level (0-31) for day and nighttime driving.

    Display/Button Illumination Dimmer:
    The display/button illumination dimmer can be set to Off (normal brightness at all times), On (display/button illumination is always dimmed), or Auto (display dims when 12-volts is applied to the orange/white illumination lead).

    Remote/Bluetooth Control

    Wireless Remote Control: The KD-A645 comes supplied with a wireless remote control (RM-RK52). The remote contains Attenuator, Sound, Source, Tracking, and Volume functions. The remote operates off of a single CR2025 3V Lithium-cell battery (included).

    Steering Wheel Remote Compatibility: The head unit features an OEM steering wheel remote control input wire (blue/yellow) within the included wiring harness that lets you keep your vehicle's factory radio steering wheel remote controls when used with an optional steering wheel audio control adapter (sold separately). Please consult Crutchfield's Outfit My Car to see if your vehicle is compatible.

    Optional Bluetooth: The JVC KS-BTA100 Bluetooth Adapter (105KSTBA10, sold separately) provides Bluetooth hands-free communication and digital audio streaming functions for the JVC Arsenal KD-A645. The JVC KS-BTA100 gives you hands-free communication from your compatible Bluetooth mobile phone and wireless streaming audio from a Bluetooth enabled digital audio player, when connected to the JVC in-dash head unit. The JVC Bluetooth Adapter includes a super-sensitive microphone, an Answer/End button, and playback controls. The JVC Arsenal KD-A645 can be set to automatically mute any music audio to your vehicle's speakers so you can listen to your telephone call using your car speakers.
