Just for fun, heres the Birth Certificate of my Arc Audio SE2300 tested at 2ohm Stereo. It's a pretty cool amp. It puts out 1300 x 1 @ 2ohm and 4ohm! Great universal amp.... Not to mention SUPER clean!

Hell Ya! Right On GC! With that amp, you're ready to upgrade to the BL or BTL!! I love FI Subs. I currently waiting for TWO Fully Loaded BL15's with the new 4" Voice Coil upgrade to put in my truck. I hope to have an update soon. I'm currently in the process of building the box. I have a dodge Megacab diesel and I can fit a 7.5cuft box behind the seat which will suit the BL's really nice. I've already second skinned the truck with damplifier pro from my toes under the dash to the back wall. I'm getting there slowly but surely. I need to order all the 0 Gauge, my HO alternator (DC 270xp) and 3 more Kinetik 3800's and I'll be ready for some good daily Bass! that was fun! lol

No Problem Swift. I'm also excited to try sundown.

I too was impressed with the results from the test. I truly was just hoping that it at least put out the 2500 watts Minimum that is advertised so of course I was super happy to see it to be a little healthier then expected. Although I know in a vehicle, I'm not going to be able to supply it with 300+ amps and hold a solid 14.4v so knowing it does 2500 watts @ 12 volts keeps me smiling still. I'm going to be going back there probably next week. I'll see what i have at home they can test. Maybe I'll have them test my Arc Audio SE2300 I have.... I know it puts out good power because I tested it in this kids truck...

Save yourself the Time, because honestly i really don't care. You don't know what they paid for it, and I don't know either. I only know what they said, and I don't really care. They test some of the CLEANEST amps on the planet and the equipment they use is capable of testing as low as .0003? or is it .00003 THD %. So if it works for them, who am i to judge? I saw him test a different amp (the SE4000) on the SAME SETUP that destroyed the RF2500 from top to bottom in Quality and Power. I don't need to see anything else. It was all I needed to see. The RF 2500 performed well within the range it is spec'd out to be on the original birth sheet and that's plenty good enough for me. There's A LOT worse amps out there then the RF 2500 and I already know the RF power series amps put out good power. Ive installed plenty of them to know first hand.

I wouldn't even of tested the RF2500 if people weren't saying the Birth Sheets were crap..... So I guess if you didn't know... now you know. RF Power Series, It'll do at least what they say they will do.

Ya I can do that GCS8. But i'm not trying to turn this into a contest with Sundown. I'm not against sundown in anyway. I want to try their product for myself. My Ears the my bass dyno lol

IDK.... how much is it at UBUY? Robert Lynn Owns Ubuy and Arc Audio....

What analyzer was it? Same with the power supplies, not exactly expensive for lab supplies and yes I know I used to be the Elgar/Sorensen rep. CEA compliance doesn't require any of that btw. just for you M5. Not sure if this will stop you from hating already but here it is. I called and this is what they use. Analyzer = Audio precision System 2 - #2322 Power Supplies = HP 6681A - 500 amps @ 8volts paralleled to 16 volts... x 2! I don't know shitt about that equipment so why don't you TELL ME about it.

$2700 may be the retail on it, but i'm sure " SUNDOWNZ " understands the cost of and quality of a board to putout over 4,000 watts at less then .09% THD @ 12 VOLTS. it's .005% at 14.4v.... Class H Quality isnt cheap.... Best of the Best. Actual Tested Rating @ 12 volts (Random Production Unit ser#60026) 1 Channels @ 4 ohms 1198 Watts 1 Channels @ 2 ohms 2311 Watts 1 Channels @ 1 ohms 4366 Watts THD @ full power 1ohm .09% * Audiophile sound quality based design * Designed by Robert Zeff * Class H switching design * Microprocessor controlled design * Microprocessor controlled Code based flashing diagnostics * Concealed adjustment controls * 24Db per octave Low pass crossover (Bandwidth limited) * Internal chassis force cooled speed controlled dual fans for optimum cooling * Hi/Low level balanced switchblade RCA inputs for maximum system integration * RJ45 Ethernet input connections for true balanced input connections * Block type terminal connections * 256 color user selectable illumination circuit * Combined Bias circuit and temperature regulation circuit to regulate bias and lower THD at any point in total thermal cycle * Microprocessor high voltage power supply allows the amplifier to optimize power output at different ohm loads without the loss of efficiency or sound quality * Vdrive based preamp stage improves efficiency lower internal signal loss * Hand picked ultra hi voltage output devices used in the SE4000 * 3 stage bank of self branded ultra low ESR 105 degree Celsius caps increase power reserves for each of the amplifiers 6 voltage rails * massive combined output inductors eliminate any unwanted A/C ripple in the amplifier increasing the amplifiers stability, while lowering the THD and increasing the S/N ratio. * Equipped with Dual 1/0 Power and Dual 1/0 Ground Screw Down Compression Block Terminals * Strapable Design allowing for the linking and connection of two units into one single channel of very high power of output- Capable of over 9000 watts at less than 1% distortion + over 10,000 watts at less than 3% distortion.

You want me to get the SAZ-3500 to put it up against the RF 2500? I didn't test my RF 2500's to put it up against anything else. I tested it because I wanted to know for myself what it actually put out. I'm a skeptic when it comes to Birth Sheets also, but I saw the proof, and I'm happy with it. Ive heard nothing but good things about Sundown and will be getting one or installing them for my next customer. When I get one I will gladly test it. But like i said, i'm not doing testing to put any brand down.

I watched him test a Arc Audio SE4000 also... Pulled 390amps and put out 4100 watts BEFORE..... BEFORE.... and I repeat BEFORE the THD level went above .005! THATS BEFORE IT WENT ABOVE .005% THD. The analyzer they were using was over $40,000 and the power supplies were $22,000 ea... they had 4 of them. Each putting out 290amps.... in the picture you can see the TWO 0 guage lines and ground lines... that was 580 amps of current. Held solid at 14.4v. I saw it all. Their equipment is legit, and there isn't an amp on the planet in the same class of quality and clarity on the same level as the ARC AUDIO SE SERIES " THAT I KNOW OF ". ON TOP OF THAT, the SE4000 they tested is Rated and also put out 4,000 watts @ 12 volts! 12 volts to 14.4v didn't matter, still held a .005% THD level... if not, they don't pass QC.... If that level of testing doesn't tell you anything about their equipment, then IDK... maybe you need to go there for yourself and believe for yourself.....

Good info... I didn't test the RF T2500-1BD at 2ohm. I intent to use these amps at 1ohm. I want to squeeze every drop I can out of them. Looks like if your woofers or voice coils were wiring to a 1ohm you'd pick up significant power from the RF's. You're losing 1,000 watts a piece on those.....

Make no mistake.... My Eyes are peeled for the next pre-order.... I'm getting a 3500 or maybe even 4500... no doubt!

HAHA! Ya..... I think so! I was going to anyway, but wouldn't mind trying different brands also.
