Ready to experience the jump in sound quality that only an amp can give you? JVC's drvn DR Series KS-DR3004 car amplifier can drive each of your front and rear speakers with 60 watts RMS, giving your music power and clarity. Just starting a system? You can use this rugged and reliable amp to run your front speakers with its front channels, then bridge the rear channels together to power a subwoofer with up to 180 watts RMS. Later on, you can power your rear speakers with the KS-DR3004 when you get a sub amp.
The KS-DR3004 comes with the controls you need to get music sounding right in your car. You'll find separate low- and high-pass filters for the front and rear channels 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.

Overview: The KS-DR3004 Class-AB 4-channel power amplifier is designed to drive two pairs of speakers, one pair of speakers plus a subwoofer, or two subwoofers in your vehicle. The DR-series amplifiers feature toroidal transformers to provide a stable power supply, and speaker-level inputs for ease of installation.
Power Output: The amp has the following power output (20-20kHz, 1% THD, 14.4V):
- 60 watts x 4 at 4 ohms
- 90 watts x 4 at 2 ohms
- 180 watts x 2 at 4 ohms bridged (1,000Hz)
4-Way Protection: The amplifier features protection circuitry that will shut down the unit if any of the following four conditions occur:
- Thermal: the operating temperature of the amp gets too high
- Short Circuit: there is a short circuit on one of the speaker wires
- Overload: the impedance of the connected load is too low
- DC Offset: direct current is detected on the speaker wires
Controls: The KS-DR3004 has controls mounted on one end of the amplifier. Separate controls are provided for the front channels (1+2) and the rear channels (3+4). The controls include:
- Input Sensitivity: Using these rotary controls, you can set the input sensitivity to match the line-output level of the connected head unit. The input sensitivity range is 0.2V to 5.0V.
- Crossovers: The amp has a separate crossovers for the front and rear channels. There are 3-way switches that yet you independently set the crossovers to LP (low-pass) fixed at 80 Hz, HP (high-pass) fixed at 120 Hz, or Off (full-range). The crossover slopes are 12 dB/octave.
Terminals: The KS-DR3004 has power and speaker terminals on the end of the amplifier, opposite the controls. The screw terminals can be tightened/loosened with a slot head or Phillips head screwdriver (not supplied). Spade connectors are recommended. The input terminals are on the same side as the controls. The terminals include:
- Input Signal: Two pairs of RCA jacks are provided for the front and rear line level input signals from the head unit. Also, there are two 4-pin connections for the supplied speaker level input harnesses.
- Speaker Output: Four sets of screw speaker terminals are provided for connecting four speakers, two speakers plus one subwoofer, or two subwoofers (minimum impedance 4 ohms). The terminals will accept up to 12-gauge wire.
- Fuse: One 40-amp ATC-type fuse is installed in the amp.
- Power: Three screw terminals are provided for
connecting the power, ground, and the remote turn-on lead. An 8-gauge amplifier wiring kit
is recommended by the manufacturer. The individual terminals include:
- Battery: The +B battery terminal will accept up to 4-gauge wire.
- Remote: The Remote terminal will accept up to 8-gauge wire, however, 18-gauge wire should be sufficient.
- Ground: The Ground terminal will accept up to 4-gauge wire.
Note: If you are using the Speaker Level Input, it is not necessary to connect the Remote terminal. The amplifier power is turned on and off as the unit detects an input signal (Auto Turn-On).
