Sundown amps

[TJElite]

Found some independent test data on another site. This is a serious amp. Not often do you see an amp that can be strapped to another, into a .5ohm load.

For those that really want to know what the SAZ-1500D will really do our buddy Loyd has done some serious real world testing to show you.

Test Vehicle : 05 aveo..

RMS clamp and dmm, as seen in the 12" test session..

woofers used.. 2 Mags (1.9 dcr per coil), 2 FI Q 12's (1.4 dcr per coil)

either used 1 sub or both of the pair for loads..

pure 60hz sine was used to tested.. just under audible clipping

1 amp, single 1000ca everstart maxx, factory alt

4 ohm nominal = 518 watts @ 88% efficiency (voltage fell from 14.3v, to 14.0v)
2 ohm nominal = 948 watts @ 85% efficiency (voltage fell from 14.3v, to 13.6v)
1 ohm nominal = 1510 watts @ 78% efficiency (voltage fell from 14.3v, to 12.4v)
.5 ohm nominal = 1615 watts @ 72% efficiency (voltage fell from 14.3v, to 11.8v)
.35 ohm nominal = 1748 watts @ 67% efficiency (voltage fell from 14.3v, to 11.4v)

amplifier was protection happy @ .35 with tones, and some music due to low voltage.

IMO.. one 1500d should be limited to 1 ohm nominal use in factory electrical systems.. for the sake of the car.. not the amp

now... to have fun with some juice..

1 amp, single 1000ca everstart maxx, 1 Eagle Picher 12a5000, factory alt

4 ohm nominal = 520 watts @ 88% efficiency (voltage fell from 14.3v, to 14.1v)
2 ohm nominal = 960 watts @ 84% efficiency (voltage fell from 14.3v, to 13.7v)
1 ohm nominal = 1635 watts @ 75% efficiency (voltage fell from 14.3v, to 12.8v)
.5 ohm nominal = 1890 watts @ 71% efficiency (voltage fell from 14.3v, to 12.8v)
.35 ohm nominal = 2245 watts @ 65% efficiency (voltage fell from 14.3v, to 12.8v)

amplifier did fine @ .35 with tones and music with the added battery

2 amps strapped, with both batteries (for the sake of not typing it over and over... voltage drops from 14.3v, to 12.8 the entire test... lol

4 ohm strapped = 1900 watts @ 82% efficiency
2 ohm strapped = 3150 watts @ 72% efficiency
1 ohm strapped = 3740 watts @ 68% efficiency
.5 ohm strapped = 4425 watts @ 65% efficiency
.35 ohm strapped = 5415 watts @ 62% efficiency

amps would only tolerate a VERY short burp @ .35..

Have you installed any yet?

[irupp33]

maybe something you should think about carrying toby :)

[the727kid]

He does sell them now. Look on Sundowns website for distributors :).

[Notladstyle]

those voltage drops are nice and tidy.

i bet those puppies cost more than my car.

[the727kid]

They are actually pretty cheap, picked up two for $750 barley used with 2 year warrenty :).

"barely used" with a warranty. Im assuming from a private party which actually means "used for a few months, got bored, they work fine i promise *cough* but im changing my number* cough*"

explain the : strapped to another

Two amps playing into the same load.

The 1500 retails for $599, but I will be selling them for less than that...

Yep, got my first batch in last week. So far, I have only put in a 4x100 (in our Escalade)...so far, so good. They are very impressive from a construction and design standpoint.

One of the things I like about the 4 channel is the crossover...the high / low pass goes up to 5khz, and the subsonic can actually be used as another high pass, so you can run active seperates, and even mid pass if you want to.

Thats what i liked about my PG Octane... I really wish i still had that customizing ability...
Too bad it only half works...

More like 2 weeks of use (well instaleld for 2 weeks, I don't even think he had them playing 3/4 of the time) and the kid I bought them from is good friends with Jacob (owner of SunDown).
