Well, I got to test out a new Sundown SAZ-1500D today, something I've been looking forward to now for a couple days.
This test was done in my truck. Electrical system consists of 2 Everstart MAXX batteries, a 200 amp alternator, and 4 runs of 1/0 wire (2 positive, 2 negative).
Power results were as follows:
1 ohm, car off:
19.9 x 53.7: 1070 watts, rising to 2.7 ohms. Voltage was only dropping to 12.3!
1 ohm, car on:
20.7 x 54.3: 1090 watts, rising to 2.7 ohms.
In all, for the price this amp is a great buy. I would expect some great numbers out of this amp wired down to .5 ohm and have a little less rise than I experience in my truck. Even with less voltage this amp did a great amount of power. I only gained 20 watts going from 12.6v to 14.6v!
As for the scores, I used my single 15" type-r. Meter was placed in the passenger kick for this test.
Car off: 150.7 @ 44 hz
Car on: 150.9 @ 44 hz
To compare, the kicker zx2500 did a 154.0 @ 44 hz.
Once again, not nearly as much of a gain as the kicker or orion when I turned the car on. Efficiency played a huge role in that as well. The batteries would only dip to 12.2-12.3 while the orion or kicker had no problems dropping the batteries lower than that. Obviously the kicker and orion did more power, but for a $600 RETAIL amp, I'd say it holds its own very well. GREAT PRICE, especially for the power potential.
Overall, its a solid amp for the price and will be a very good daily driver amp for .5 ohm and 1 ohm loads. While I didn't get the power out of it that some others did, I feel that it did very well in my tests. A lot better than the 20.1 did versus the hype surrounding it.
(and yes, I am fully aware of the board that is in the sundown and what amp it used to be in )
The next test for this amp (if we have the time) is to test it on a 16v setup and possibly a lower ohm load. Hopefully that will happen in the next week or so.
