Which is better for a 1-ohm subwoofer?

The Sundown SALT-1. It is rated 1000W RMS at 1 ohm with a 120A draw. The Kenwood is 1-ohm stable but regulates output to 900W.

Which has more power at 2 or 4 ohms?

The Kenwood, because it publishes those figures: 900W at 2 ohms and 500W at 4 ohms. Sundown does not publish 2-ohm or 4-ohm RMS ratings for the SALT-1.

Which is cleaner at low volume?

The Kenwood, on paper. Its 100 dB signal-to-noise ratio beats the Sundown's 90 dB, so less background hiss at low listening levels.

Is the Sundown worth the extra money?

Only if you need 1-ohm output, the wired remote, and 120A current capacity. No store price was given for the Sundown, so check its live price against the Kenwood's $189.95 at Distritech as of October 28, 2026.

Can I add a second amp later?

With the Kenwood, yes. Dual Mono Drive lets you strap two KAC-9105D amps together. The Sundown SALT-1 is a single-amp design.

Which has better bass tuning controls?

The Kenwood. It has a variable 50-200 Hz low-pass filter, 0-18 dB bass boost at 40 Hz, and an infrasonic filter. Sundown does not publish comparable controls for the SALT-1.
