XT Audio 1700W Monoblock Class D Full-Range Amplifier – 2 Ohm

The XT Audio 1700W monoblock amplifier is a compact, efficient, one-channel Class D amp built to drive your subwoofer stage with clean, reliable power. Rated at 1,700 watts and stable down to 2 ohms in full-range mode, it delivers the current your bass demands while running cool and drawing power efficiently. Whether you are powering a single high-output subwoofer or a pair wired to 2 ohms, this XT Audio monoblock is a straightforward, budget-friendly way to add serious low end.

Efficient Class D power for your bass

Class D amplifiers are the standard for subwoofer power because they turn more of your electrical system's energy into output and less into wasted heat. That efficiency means the XT Audio 1700W amp can deliver strong, sustained power without the size and heat problems of older amplifier designs. Running in full-range mode, it is flexible enough to power subwoofers or other loads, but its sweet spot is delivering hard-hitting, controlled bass to a subwoofer stage.

Stable to 2 ohms

This monoblock is stable down to 2 ohms, which is the impedance most single dual-voice-coil subwoofers or pairs of subwoofers are wired to. That makes it easy to match with popular subwoofer setups and get the amplifier's rated output. A monoblock (single-channel) design is ideal for bass because all of the amp's power is dedicated to one job: driving your subwoofer as loud and cleanly as possible.

Installation tips

To get clean, reliable output from the XT Audio 1700W amp, feed it with adequate power and ground wiring and set your gains by ear or with a meter to avoid clipping. Match your subwoofer's wired impedance to the amp's 2-ohm rating for full output, keep your ground connection short and solid, and fuse the power wire near the battery. If you are adding this to an already-busy electrical system, consider an upgraded battery or charging system so voltage stays stable when the bass hits hard.

Why choose the XT Audio 1700W monoblock

For enthusiasts who want a simple, efficient way to power a subwoofer without overspending, this XT Audio monoblock checks the boxes: enough power for a strong single-sub or 2-ohm setup, efficient Class D operation, and easy impedance matching. It is a practical foundation for a bass build.

Frequently asked questions

What can the 1700W amp power?

It is designed to power a subwoofer stage — typically one high-output subwoofer or a pair wired to 2 ohms. All 1,700 watts go to a single channel, so it puts its full power behind your bass.

What impedance is it stable at?

The amplifier is stable down to 2 ohms. Wire your subwoofer(s) to present a 2-ohm load to get the amp's rated output, and avoid dropping below its minimum rating.

Is it Class D, and is that good for subs?

Yes, it is a Class D amplifier, which is the preferred design for subwoofer power because it is efficient, runs cooler, and delivers strong current for bass without wasting electrical energy.

Do I need to upgrade my electrical system?

For a single amp of this size, upgraded power/ground wiring and a healthy battery are usually enough. If your voltage sags when the bass hits, add a stronger battery or a big-three upgrade to keep the amp fed.

What gauge power wire and fuse should I use?

Wire gauge depends on current draw and run length, but a 1,700-watt amplifier typically calls for heavy power and ground wire — commonly 4-gauge for many installs, and larger for long runs or higher demand. Fuse the power wire within about 18 inches of the battery, keep the ground short and bolted to clean bare metal, and match the amplifier's onboard fuse rating. Wire that is too thin is a common cause of voltage drop and weak output, so it is better to err toward a larger gauge and a solid ground.

Additional system planning notes

For the XT Audio 1700W Monoblock Class D Full-Range Amplifier – 2 Ohm, the original product description above remains the primary product-specific content. Before installation, also verify the final speaker or subwoofer load, the amplifier's supported impedance, available charging-system capacity, cable size, fuse strategy and installation space. A clean car audio build depends on matching the component to the complete system rather than relying on a single specification. Plan mounting, wiring, electrical support and tuning before the vehicle is disassembled, and keep model-specific manufacturer guidance as the final reference for any specification that is not stated here. After installation, test at conservative levels, confirm that every channel and connection operates normally, and then make tuning changes one at a time. This method helps protect the equipment, simplifies troubleshooting and makes it easier to achieve consistent performance in daily use.
