at 14v? you really need to back that claim, or face being called retarded.

I do not have clamp results for kicker sorry, but these are from caco.

sundown(2) SAZ 2500s (not strapped)

-.5 nominal rise to .9

-drop to 12.5volts

-4,430 watts total, 2,215 from each amp

HUH?....that make no sense. lemme decipher that...ok, you say avg. at .75 ohms = 2215 watts from 1 saz 2500 at 12.5v? wow....and what was the clamp on the other end of that thing showing? how many amps was it using to make that?...I bet Kicker still kicks it's *** all over and up and down.....Like I said in the beginning, there is no argument.....do you want an amp that uses more current for the same power output OR one that uses less with minimal added distortion??? That is the only true comparison between the two.... 75% efficiency or 60%? How clean and undistorted do you want the signal???

It says that each 2500 started at .5 nominal and rose to .9 (you do not take the average of the nominal and actual, you just use the actual which is .9), with voltage dropping to 12.5, each amp put out 2,215 watts. These are not my clamp numbers, they are from the official clamped numbers thread on caco. There are other sundown 2500 clamps, but they do not show either voltage or rise, so I left them out. Distortion is very hard to hear in the sub stage, I do not notice any difference in SQ going from being strapped at 4 ohms to being strapped at 1 ohm.

There is nothing wrong with the kicker, and it will be more efficient. However, at 2 ohms nominal, you aren't going to see close to rated power after rise. I understand increased strain, but if your electrical is up to par, it is not really straining it then. Most drop on music (Decaf) running 2 2500s strapped at 1, and 1 100.4 with a 300 amp EA alt, Odyssey group 34, and D3100 in trunk is .3 volts @ 2000 RPM. I get more drop at idle sometimes up to 1.5 volt drop, but only if the belt slips. Again, I would chose a DP over a warden on that power.

So you keep mentioning this "Strapping thing" I know the reason and all, but you are talking about running another $1600 worth of equipment to get up to your idea of par.

I payed a little over 1/2 that for the equipment mentioned above, and their are less expensive routes as far as batteries, but space and weight were already an issue in my vehicle, and up to par for a 2500 watt system is quite less than 5000+ watts. Lets not forget, the OP is talking about running an $800 dollar sub as well.

I can without a doubt state that a Kicker ZX2500 would put out 2400+ at 12.5 at 2ohm nominal with less harmonic distortion. The old Kx series were even stouter boards with more dampening and 1 ohm stable.

I actually read somewhere that the Kx was between 80 and 90% efficient at 1 ohm too. But without actually being able to throw #'s down, I used a very conservative 75% figure.

being as i have heard and had some experience with both the kicker amps lack of crossovers left a lot to be desired i would take the saz2500@.5 over the kicker @2ohms just my opinion.

So your saying the kicker at 2 ohm nominal rising to almost 3.6 ohms (which would be a fair comparison, as the sundown clamp was from .5 to .9, which I might add is a very efficient box, as in a daily app, 3 or 4x rise is normal), will put out 2400 watts at 12.5? I will be waiting for a clamp vid starting at 2 ohms nominal and seeing 2400 watts at ~12.5.

you do realize to make 2500w at 1 ohm or 2ohm it will take 250amps of current either way right? all you 2ohm is more efficient than 1 is bull crap look at the fuse rating on the kicker and the sundown its the same 250amp fuse. they are designed to use 250amps of current to make their power ohm load doesnt mean crap when comparing two amps that make the same power at different ohm loads

that only works with comparing amps efficiency of running a 1 ohm amp at 2ohm at the same wattage.

remember it takes power to make power the actual percentage of difference might be 2% of efficiency

I would beg to argue the differences between the saz efficiency at 1 ohm rated output and the ZX efficiency at 2 ohm rated output. I would bet the difference is more in the 10-15% range, But conveniently, neither one of those figures are readily available for either one of us to support. Now, there is one little factoid available that you mentioned. The SAZ is rated for 250a fusing and 86% efficiency with 600 watts at 4 ohms....the ZX, on the other hand is rated for 300a fusing and claims 90% efficiency with 1200 watts at 4 ohms....how does that twist u noodle?

The warden actually come in dual .7 or dual 1.4 coils. And i would get a bigger amp then a 2500. My warden laughed at my dc 2k, just gave it a tickle.
