*New Test: Sundown SAZ-1500D*

[tommyk90]

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.

Nice job man.

[.::DuD3::.]

are these the new hyped amps? stats look pretty good.

Yes it is, and yes they are.

Overall, i'm much more impressed with the sundown than I was with the 20.1, which is ironic for the people who know what I'm talking about.

Now thats a solid review, good job. and can i ask why it was ironic with th 20.1?

[tommyk90]

Now thats a solid review, good job. and can i ask why it was ironic with th 20.1?

Well, i've been told by more than one person that the sundown is a close cousin to the 20.1

But i've been told the opposite by others. Maybe jake can come in here and clear this up for me. Would be a lot better than others spouting off stuff back and forth.

[Wkbdkid]

O so i take it that the 20.1 didnt do soo hot in your setup?

Never tested it in my setup. In my teammates setup it left something to be desired. But that was a topic for another thread. I'd rather not get into it in this thread.

Cool.

Nice Test tommy... to bad u cant get the power out the amps like loyd.... i cant either so dont feel bad lol

[ngsm13]

Master your impedance rise... hehe.

Thats actually the least impedence rise that I've ever had in my truck.

great review

[Immacomputer]

Test it at different frequencies to get the impedance rise down. Right now we're looking at a larger difference from apparent to actual power due to your impedance rise. You're going to see more variation because you're calculating power by using Vrms*Irms and that only gives you apparent power. With an impedance rise like that, you're putting a pretty large variation due to the imaginary load that is combined with the resistive load.

I'll be honest, I know NOTHING about impedance rise... but if Immacomputer is correct then I too would like to see actual power... my four Sundowns come tomorrow via UPS, I can't wait
