looking to get 425 shipped OBO

i also need an amp that does ~2500 @ 2ohm IE kx/zx 2500.1

ill try and get pics tomorrow, if not ill have them on wensday.

cosmetically id give it a 7/10, theres some scratches along the mountin holes, but it works perfectly.

edit: yes, i know i cant spell wensday, ive given up on trying.

im not positive what it will do at .5, but ive heard of it doing well over 2k at 1 ohm, 2400 IIRC but that may have been at 16v, im not real sure... and ya, these are built like a tank, they can definetly take some abuse....

nope it was on a regular 12v system. it did 2.4kw @ .98 ohms (wired to .25 i believe) at 11.1 v

so, this amp will do 2400watts@1ohm on 12v? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

According to "testing"

wow, i didnt know that...

Maybe i havent been studying then, or reading...

Yeah I'm a bit skeptical

I had one running at 0.5 ohm nominal, and I highly doubt it was spitting out much over 2kw

And that 2400 @ 1 ohm is 1 ohm after impedance rise, it's 0.25 nominal, so that might be reasonable.

Me too...

Yeah I'm a bit skeptical

me to, i mean i loved this amp, but i cant see it being underated by that much...

tests have shown:

allright we now tested the IA @ .25 ohms dcr. not too shabby with the results, but it was still less efficient than the kicker and drew more current doing so.lets compare:

kicker @ .5 dcr, rise up to 2.2 ohms - 25xx watts

IA @ .25 dcr, rise up to .98 ohms (not bad), 2458 watts

with the kicker the voltage dropped to 12.4

IA it dropped to 11.5

we couldnt get a full burp out of the kicker @ .25, it had a few more clicks left on the volume, but we got a 151.3 out of it, a few more clicks and it would have come close to a 153

the IA did a 152.0 flat @ .25 with a full burp out of it.

so the IA's aren't bad amps, they just need to be ran at a really low load and you have to have the voltage to back em up. which in my case the kickers would be more efficient for me. So I have no bad feelings about IA, this was never meant to be a flame war, i tested their amp out, i posted the results I got with them. And I chose the amp that was the most efficient that did great power for me.

the IA actually did OVER rated power rising up to 1 ohm. But I had to wire it down to .25 to get those results. supposed to do 1800x1 @ 1 ohm. i got 2458 watts. Not a shabby amp at all, just not going to work with my coil configurations, and i cant run daily @ .25, kept goin into protect on me, but that can be a voltage issue not an amp issue.

the higher your box rise (ie the case with the kicker) the farther skewed the results are (but i dont see anyone arguing the kicker isnt doing 2500w....)

IA did a 152 off 4 95 series DD subs on the TL

kicker did a 151.3 off the same subs on the TL

could not get a full burp off the kicker...so considering it had to be wired down to .25 ohms and still got shut out...

both amps wired to .25 ohms...again...i dont see anyone argue the specs on the 2500.1's. ive owned both, love both, and would use either one any day of the week. what im trying to say is....buy this mans amp!

bump.

dont make me sell my purdy lil sub just cuz i cant afford a new amp for it //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
