Our take on the SAEv4-2000.1D Amplifier

The Sundown Audio SAEv4-2000.1D is a 1-ohm monoblock car amplifier rated at about 2,000 watts RMS, built with Class D half-bridge circuitry. It revives the Korean-style SAEv1 and SAEv2 formula with a new chassis and a heatsink carrying 33% more aluminum for better cooling under heavy loads. It suits bassheads who want strong subwoofer power and half-bridge stability without stepping up to premium full-bridge amps. Rivals in its class often cost more for similar output, but this one is a single-channel amp only, so it drives subwoofers, not door speakers.

About the SAEv4-2000.1D Amplifier

The SAEv4-2000.1D is a Class D monoblock car audio amplifier from Sundown Audio. It is a budget-friendly, Korean-style design that brings back the approach of the SAEv1 and SAEv2 series. It is stable down to 1 ohm and delivers 2000 watts RMS at that load.

The chassis and heatsink are new and use 33% more aluminum for cooling under heavy loads. The amp uses half-bridge technology, which keeps it compact. It has a dual MOS-FET PWM power supply and a 4-way protection circuit covering thermal, voltage, speaker short and DC offset faults.

It has a variable low pass filter and a variable subsonic filter, both at 12 dB/octave. A wired remote control is included in the features.

Questions and answers

How much power does the SAEv4-2000.1D make?
It is rated at roughly 2,000 watts RMS into a 1-ohm load. That is subwoofer power, so match it to subs rated for that range.
Is it 1-ohm stable?
Yes. It is a 1-ohm monoblock, so wire your subwoofers to a final 1-ohm load to get its full rated output.
How is it different from the SAEv1 and SAEv2?
It keeps the Korean-style half-bridge design those series were known for and adds a new chassis and a heatsink with 33% more aluminum for cooling.
Can it power door speakers?
No. It is a single-channel mono amp meant for subwoofers. Use a multi-channel Class A/B amp for full-range speakers.
What comes in the box?
The box contains one SAE-2000-V4 amplifier. Wiring and installation hardware are not included.
Will my stock electrical system support it?
At full output it draws heavy current, so plan on an upgraded alternator, battery and wiring. A stock electrical system will limit it.
