How much power does the SALT-1700.5 make?

Tested at 12.8V, it rates 125W x 4 plus 480W x 1 at 4 ohms stereo, 220W x 4 plus 800W x 1 at 2 ohms stereo, and 1300W x 1 at 1 ohm mono on channel five.

Can it run a whole system on its own?

Yes. Four channels drive front and rear speakers while channel five runs the subwoofer, so one chassis replaces a four-channel plus a mono amp.

What ohm loads does each channel take?

Channels 1-4 are 2 ohm stereo stable. Channel 5 is a monoblock rated down to 1 ohm.

What crossovers does it have?

Channels 1-4 get variable high-pass (20Hz-5kHz) and low-pass (50Hz-5kHz) filters. Channel 5 gets a 50Hz-500Hz low-pass and a 10Hz-100Hz subsonic filter, all 12 dB/octave with X1/X10 multipliers.

What fuse and wiring does it need?

Sundown recommends a 200A fuse rating, so plan on heavy-gauge power cable and a charging system that can support it.

Is the wired remote included?

No. The wired remote with voltage and temperature display and clipping indicator is optional.

Our take on the SALT-1700.5 5-Channel Amplifier

The Sundown Audio SALT-1700.5 is a five-channel full-range digital car amplifier built to run a whole system from one chassis: four channels for front and rear speakers plus a dedicated subwoofer channel. Its SALT low-voltage design is aimed at vehicles whose electrical system sags under load, and the sub channel is rated to 1 ohm mono for heavy bass duty. It carries the tuning tools a serious installer expects: variable high-pass, low-pass and subsonic filters, crossover multipliers, a clipping indicator and four-way protection. Against typical five-channel amps it trades a compact footprint for real sub-stage power, so it suits people running one amp for everything rather than a budget drop-in.

About the SALT-1700.5 5-Channel Amplifier

The Sundown Audio SALT-1700.5 is a 5-channel full-range digital car amplifier. SALT stands for Sundown Audio Low Voltage Technology. It uses a high-efficiency digital multi-channel design.

Channels 1-4 are stereo stable down to 2 ohms. Channel 5 is a monoblock channel stable down to 1 ohm. Each channel group has its own variable filters, with X1/X10 crossover multipliers and a clipping indicator.

A 4-way protection circuit guards against thermal, voltage, speaker short and DC offset faults. An optional wired remote control shows voltage and temperature and has a clipping indicator.
