Serious Power for Mids and Highs

The DC Audio 250.4 isn't your average 4-channel car audio amplifier.

While many traditional 4-channel amplifiers are designed for modest speaker upgrades, the DC Audio 250.4 is engineered for high-output audio systems that demand substantially more power.

Producing 250 watts RMS per channel at 4 ohms, this amplifier delivers excellent output for demanding midrange speakers and high-performance full-range applications.

At 2 ohms, output increases to 400 watts RMS per channel, giving you a total of 1,600 watts RMS across all four channels.

Need even more power per speaker? Bridge the amplifier into a two-channel configuration for 850 watts RMS per bridged channel at 4 ohms, delivering an incredible 1,700 watts RMS total output.

This versatility makes the DC Audio 250.4 an excellent choice for custom door speaker installations, high-output mids and highs, and serious competition car audio builds.

Built to Keep Up with Your Bass

250 Watts RMS Per Channel at 4 Ohms

The DC Audio 250.4 delivers substantial power to high-performance midrange and full-range speakers, helping your system produce the output needed to compete with powerful subwoofer setups.

400 Watts RMS Per Channel at 2 Ohms

For even more output, the amplifier delivers 400 watts RMS per channel at 2 ohms.

This makes it an excellent choice for properly configured multi-speaker installations and high-output door panels.

Bridgeable for 1,700 Watts RMS

Need serious power for larger speakers or high-output applications?

Bridge the DC Audio 250.4 into a two-channel configuration to produce 850 watts RMS x 2 at 4 ohms, giving you 1,700 watts RMS of total available output.

Advanced High-Pass and Low-Pass Crossovers

The DC Audio 250.4 features adjustable high-pass and low-pass crossover controls, allowing you to tailor the frequency range delivered to your speakers.

Whether you're powering midbass drivers, dedicated midrange speakers, or other high-output drivers, these controls help you build a properly tuned system.

Versatile Crossover Modes

With selectable HPF, FULL, LP, and BP modes, the DC Audio 250.4 provides the flexibility needed for a variety of speaker configurations.

Its x10 crossover multiplier extends the adjustable frequency ranges, making it especially useful for custom multi-speaker and high-output car audio systems.

Efficient Class D Amplifier Design

The DC Audio 250.4 utilizes Class D amplification technology to deliver high power output with improved efficiency compared to traditional amplifier designs.

Heavy-Duty Power and Speaker Connections

Serious power requires serious connections.

The DC Audio 250.4 features 1/0 AWG power and ground inputs along with 8 AWG speaker terminals, allowing installers to use substantial wiring for demanding audio applications.

Power, Protect, and Clip Indicators

Integrated LED status indicators provide convenient feedback on amplifier operation, including power, protection, and clipping status.

A remote control connection with clipping indication adds another level of monitoring for your system.

Important Installation Information

The DC Audio 250.4 is NOT 1-ohm stable.

This amplifier is designed to operate at a minimum impedance of:

• 2 Ohms Per Channel in Stereo Mode
• 4 Ohms Per Bridged Pair

Operating the amplifier below its specified minimum impedance may result in overheating, protection mode, or amplifier damage.

For best performance, use properly rated speakers, adequate power and ground wiring, appropriate external fuse protection, and a correctly designed electrical system.

When powering high-frequency drivers or tweeters, always use suitable crossover settings and ensure the speakers can safely handle the amplifier's output.
