DS18 SXE-1200 4/BK Car Amplifier Stereo
INTRODUCTION
The DS18/ SXE amplifier is for high-quality audio reproduction for the audiophile and the everyday listener alike. Allowing you the ability to tailor the sound to best fit the speakers and your listening preferences ensures solid electrical connections that resist corrosion. Fully variable crossover. Additionally, they may be used in conjunction with
outboard passive or active crossovers, depending on the complexity required by the system. The 12dB per octave slope offers a steep roll-off above or below the selected frequency. Protection circuitry against overload, short circuit, thermal, low voltage, high voltage, and reverse polarity. These protections are designed to protect the amplifier from misuse, as well as from common causes of amplifier failure.

INSTALLATION
- Professional installation by an authorized DS18 amps dealer is highly recommended!
- Otherwise, the performance of your new gear may not be satisfactory. If you decide to do your own installation, please read and follow this manual very carefully.
- Failure to do so may compromise the integrity of this product, your automobile, and possibly void the product warranty.
- Amplifiers are generally mounted in the hatch/trunk area of a car or SUV, and under or behind the seat of most pickup trucks. Select a location that will provide adequate ventilation for the amplifier. Avoid mounting the amplifier with the fins facing down. The fins should be facing up, either vertically or horizontally. Secure the amplifier with the screws provided.
- Before securing the amplifier, inspect the mounting location carefully to ensure that you do not drill into or damage any electrical, hydraulic, fluid, or fuel lines.
INPUT
- Because of the wide range of head unit output configurations, all DS18 / SXE Series amps have an adjustable input sensitivity of “Gain”; the gain is not a volume or a power limiting control like a throttle.
- It makes the amp more sensitive to input from the stereo. With the gain up, the amp will reach full output at a lower volume setting on the deck. At higher gain settings, the amp also becomes more sensitive to noise from the car’s electrical system.
- Try to run the gain at the lowest setting possible for your system.
- There is no correct gain setting. Because speakers require different power demands to reach the same output, the gains most often need to be used to compensate for these differences. If you tried to set all the gains at halfway, you would probably find the system didn’t sound excellent. Using good judgment and listening carefully is still the best way to tune a system.
CROSSOVER CONTROLS
- A crossover is a device that removes unwanted frequencies from a speaker or amplifier. A tweeter can easily be destroyed by bass notes if they are not filtered out. Likewise, a subwoofer will not sound natural if it is playing midrange notes.
- A crossover removes these sounds from the speaker. As you might guess, careful adjustment is needed to ensure that all the speakers are playing the right sounds and that you are left with no “holes” or low spots in the frequency response.
SPEAKER OUTPUTS
This amplifier is a multi-channel amplifier design. Meaning it has more than one channel of speaker outputs. Make this connection carefully and neatly. Strip your wire back and twist the exposed leads, and insert them into the block terminal while being
Careful that there are no loose or frayed strands of wire, and tighten the hexagonal head screw down on the terminal till the wire is tightly secured in place. If the wires ever come in contact with each other, the amplifier will go into protection. Know your total ohm load before you make any connections.

DS18 SXE-1200 4/BK Car Amplifier Stereo-FAQs
How much power does it output?
It delivers 60 watts RMS x 4 channels at 4 ohms, for a total of 240 watts.
What is its main purpose?
To cleanly power four full-range car speakers (like door or coaxial speakers) for significantly louder and clearer audio.
Is it easy to install?
Yes. Its compact design allows for easy installation in tight spaces under seats or in trunks.
What class of amplifier is it?
It’s a Class A/B amp, known for its excellent balance of high-quality sound and power efficiency.
How do I set the gain control?
Play music at ¾ volume from your stereo and slowly turn the gain up until the sound distorts, then lower it slightly until it’s clean.
What are the LPF and HPF filters for?
The Low-Pass Filter (LPF) is for subwoofers (bass), and the High-Pass Filter (HPF) is for speakers, blocking unwanted frequencies for cleaner sound.
Why is there no sound from the amp?
Check the basics: power, ground, remote wire, and fuse connections. Ensure the amp is not in “Protect” mode, which indicates a wiring issue.
What does the “Protect” light mean?
It means the amp has detected a problem, usually a short circuit, overheating, or impedance that’s too low. Check all speaker wiring.
Will it improve my sound quality?
Absolutely. It provides clean power that reduces distortion and allows your speakers to perform at their best, revealing details your factory radio can’t.
