Bold styling keeps up with performance

JVC's DRVN Series car amplifiers are all about power… with style. These amps feature aggressive looks, strong value, and plenty of power packed into a rugged housing. The DRVN KS-AX3204 4-channel amplifier, for example, can power your sound system with 60 watts RMS for each of your front and rear speakers. And this JVC doubles as a bass amp — you can put the KS-AX3204 into 2-channel mode and run a pair of subwoofers with 150 watts RMS each.

Versatile features

The KS-AX3204 comes with the controls you need to get music sounding right in your vehicle. You'll find separate front and rear low- and high-pass filters at your disposal, allowing you to tailor the amp to driving full-range speakers or subs. And speaker-level inputs allow you to hook this amp to almost any car stereo, even a factory system.

Product Highlights:

  • 4-channel car amplifier
  • 60 watts RMS x 4 at 4 ohms (90 watts RMS x 4 at 2 ohms)
  • 150 watts RMS x 2 bridged at 4 ohms (4-ohm stable in bridged mode)
  • CEA-2006 compliant
  • separate switchable high-pass (150 Hz, 12 dB/octave) and low-pass (80 Hz, 12 dB/octave) filters on front and rear channels
  • Class AB amp technology
  • MOSFET power supply and output stage
  • preamp and speaker-level inputs
  • fuse rating: 40A x 1
  • 8-gauge power and ground leads recommended — wiring and hardware not included with amplifier
  • 13-1/2"W x 2-1/4"H x 7-3/8"D
  • warranty: 1 year
  • Our 60-day money-back guarantee

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Nice addition to my set-up

Written By Brendon, Bakersfield, CA on Thursday, October 03, 2013

I added this amp to my system once I decided to upgrade my speakers. I have a 2005 Tundra DC. Head unit is a JVC KD X50BT. I am running Alpine 6 1/2 coaxial speakers in rear doors and components in the front. The amp fit nicely under my passenger seat, just had to modify the air vents. I finally have great sound in my truck. You can really hear all of the highs and lows in your music.

Pros: Great amp with lots of power for a very reasonable price. Easy to set the gains and easy to install.

Cons: Wish it had a pre-amp out for a sub.

Product Research


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 measuring 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 with 1% or less Total Harmonic Distortion plus noise (THD+N) over a frequency range of 20 Hz to 20 kHz (for full range amplifiers). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4Ω. CEA-2006 allows consumers to compare car amplifiers and receivers on an equal basis. Using CEA-2006 criteria, the JVC KS-AX3204 is rated as follows:

  • Power Output:
    • 4Ω: 60 watts x 4-channels
    • 2Ω: 90 watts x 4-channels
    • Bridged: 150 watts x 2-channels (into 4Ω)
  • Signal to Noise Ratio: 76 dBA

Crossover: The front and rear sections of the amplifier have independent crossovers. Each has a 12 dB/octave slope and can be set to high-pass with a crossover point of 150 Hz, off (full range), or low-pass with a crossover point of 80 Hz.

Power Connections: The power and ground terminals are nickel-plated screw terminals. They will accept spade connectors or ring terminals up to 0.5" wide. The remote turn-on terminal will accept a spade connector or ring terminal up to 0.35" wide.

Speaker Connections: The speaker outputs are also nickel-plated screw terminals and will accept spade connectors or ring terminals up to 0.35" wide.

Speaker Level Input: Two speaker level input harnesses are included (front and rear), making it easier to add an amplifier to a factory radio or to a receiver with no preamp outputs.
