WTB: Amp that does 1500@1

[whitedragon551 5,000+ posts]

I need an amp that does about 1500@1 a little more, but no less.

Budget is around $170 shipped or less. I may have some possible trades, but Id like it to be no more than $170 with trades.

Looking at a refurb SAE1200d from DB-r (go for $150 shipped from him), AP15001d, AP18001d, Powerbass ASA1500d, or anything else. Offer up what you have with a pic and screen name and a price. Anything without a screen name and price will be disregarded.

What does that mean....with trades?

Ive got some stuff up for sale I can toss in as trades so that I can stay at my $170 budget incase the asking price is actually over that.

what kind of stuff for trade? i have my audiopipe gd6001 up for sale or trade. maybe we can work somthng out

You say no less than 1500, but youll take an sae1200?

Yup. Have you seen the clamp tests on them?

I thought the sae series puts out right at rated power.

But no i havent seen tests on them.

Nooo. Jacob clamped one and it did 1770@1. DB-r clamped one and it was doing 1500@2.

Not much of a difference between the two tests for going from 2ohm to 1ohm. They must have used two different SAE 1200d amps and different test methods.

They did use different methods. The review was on DB-rs page. Heres what I could gather from both tests.

DB-Rs Test

First, let me make this clear, that this is NOT a "laboratory test". This is just a quick test of the amp here on our bench with our load testing setup, which really works better for amps under 500 watts to get accurate numbers at various voltages etc. This was just a quick test, but we did use Fluke meters for measuring the output voltages and current, and did use our oscilloscope for the unclipped power tests.
I know everyone wants to see the numbers so let me throw those out there first and then you can read the rest of the review:

Max Power Tests, with no regard to clipping:

40hz

65VAC 23Amps @ 12.5V = 1495 watts @ 2.8 Ohms

60hz

51VAC 25Amps @ 12.0V = 1275 watts @ 2.04 Ohms

65hz

48VAC 27Amps @ 12.0V = 1296 watts @ 1.78 Ohms

Unclipped (clean sine wave output) Power Tests:

40hz

55VAC 14Amps @ 13.2V = 770 watts @ 3.93 ohms

52hz

40VAC 20 Amps @ 12.5V = 800 watts @ 2 ohms

60hz

38VAC 22Amps @ 12.5V = 836 watts @ 1.73 ohms

69hz

39VAC 22Amps @ 12.7V = 858 watts @ 1.78 ohms

Jacobs Test

Just an update here, speaking with Sundown Audio they have reported these numbers from this amp using a larger power supply than what we have here, they have 120Amp Cont. 180amp surge power supply and three big batteries and this is what they reported to me:
***** from Sundown Audio

43.3 Amps

46.7 Volts

1.08 Ohms Actual

----

2022 Watts

*****

This is actually .93 ohms, there may have been an error there in which number they divided by, you are supposed to divide the voltage by the current, not divide the current by the voltage. But either way, this is an actual 1 ohm load. **Correction, I was reading their numbers in the wrong order, this is at a 1.08 Actual load... My bad!**

This would be 144 amps of current draw from the power supply and batteries at 14 Volts DC if the amp were 100% efficient, I would think it's more like 80% at best efficient at 1 ohm, so would be around 170-180 amps @ 14VDC.

Either way. Bump
