Hello everyone! Yes I am the one with the K9s. There has been a lot of talk about why no pics have been shown and why no results and this and that, this and that!! First of all, I am not the type to boast about products or put down products publicly. To me its all about what the owners of the product wants me to do. You all know I have been very busy so I could not devote my time strictly for testing on any amp. Now I have some paliminary testing with the K9s.

I would like to say this is one of the most meaty 9k amps I have every seen. You can actually see the windings on the terroids with out seeing the internal part of the terroids that the windings goes around. It is heavy, and its weight is definitely not based on its casing, it is mainly based on its internals. I mean it is solid. Its about 10 inches wide and 35 inches long. It is rock solid. It is also fanned cooled. The fan is not too loud but you definitely can hear it.

Performance wise it is the strongest amp in its class. Now these are unofficial numbers, meaning I usually test about 10 times before I post numbers but I tested it about 3 times. So I reserve the right to change my testing numbers. I tested the amp Street a style off of one g2400 battery with one 10 inch dual 1 ohm dd9500f. Before burping I let the voltage drop to 13.2 And man, I have to say it is the most efficient amp I have every tested.

The paliminary(spelling)results are:
102.1 volts
54.5 amps
5564.5 watts
0.5 nominal, 1.87 ohms box rise
get this voltage drop of 10.5 and stablized.

What I mean by stabilized is that, I held the burp for 5-6 seconds, the voltage dropped to 10.5 and stayed there. This is a bad azz amp. But more testing to come. I believe they are priced fairly, if interest, pm Christoph for pricing. My elite has about 200 burps on it, I just opened up for the first time yesterday, NO EVIDENCE OF ABUSE, BURNING, FRYING....NOTHING. And the amp still smells brand new. The K9 version for 16 volt cars would be well worth trying. Even the elite 12 18 volts version would be great to try...IN MY OPINION!!!

You should make a table of testing you have done with all these amps Ray, that would be a great resource!

My American bass did only 5250 at 1ohm dropping to 10.7 on my odyssey 1750 so this amp is at least on par with the 1000.1 very nice too bad it's 35" long

The voltage drop was measured at the amp, at the battery it read just a little over 11.0 volts.

OHH, two k9s will probably beat that by 1000-1500 watts.

I used my K9s in a 1x event. Usually my score is 156.0 with the elite 12. I did a 155.8 with the k9s at 0.5 ohms. The voltage drop was 10.5. Hopefully I can get a little more out of this amp at 0.25 or 0.35 at nominal.

Guess what guys, I left the show and did some testing at my house. This is the most efficient amp I have ever owned. I missed burped it at 59hz and got a score of 155.5. For chits and giggles, I said let me see what it does without charging the battery. Without charge, without turning the amp off or opening the car do to do anything, I adjusted my head unit, remotely to go to 60hz, burped it and did a 155.8. This is without a doubt the most effient amp I have ever owned.
