Will it be ok to wire my ZX2500.1 to a .5 ohm load?

[JarvisB 10+ year member]

I have a Cascade Designs Omega 15" D1 in a 3.5 cu ft compression box with aeros tuned to 32 hz.

I am wondering if it would be ok for me to wire the sub to 0.5ohm load since after the impediance rise, the amp will end up seeing 2 ohm?

ZX2500.1 is rated 2500 at 2 ohm

I m trying to see if I can get the more out of this amp by doing this because from what I have figured, if I wire the sub to 2 ohm load then after the rise the amp will be seeing some more than 2 ohm. Am I making any sense?

Any help would be appreciated, thanks.

After rise and all you should honestly be fine, just make sure your electrical is up to par

idk man, I've heard of people having trouble with them at 1 ohm

But i've never used one so.....

I hear they can do 1 ohm alright, but will protect at .5 ohms. I guess its worth trying.

lol at this thread. i have used kicker amps and they hate 1 ohm! much less .5

I Had A 2500 Wire.5 For Like 9 Months 1 Sub Blew And The Other Just Quit Workin

I see, but my point is that the amp wont even be seeing .5 ohm?

Im wondering if it is possible to calculate the imp rise by looking at the set up? I m wondering how much of imp rise am I looking at?

And my electrical floats around at 14V at average.

And is the amp fine still?

cant calc. imp. rise. it has to do with box, car acoustics and other factors that are hard as hell to calc. just put a dmm on it and u can burp it for 3 seconds and do some formula to get ur imp rise on a tone

I would not recommend it. .7 would be the lowest i would even attempt with solid electrical.

NO WE HOOKED IT UP TO 2OHMS ON 2 18" FI BL AN THE AMP BLEW I GUESS

Interesting. I m not sure about my amp when it comes to voltage rating.

.7 before the imp rise? I am not sure how much of imp rise does everyone normally see, but I am assuming I should at least get 1.5 ohm load after the imp rise when I wire it at .5

Lets say my box is just like any other box, then would it cause a 1.5ohm imp rise?

I dont recommend running it at .5 unless you are sure your impedance will rise very close to 2. Which is a good amount of rise.
