Had no problem with mine at .5however.... issue that 2500d isnt really stable at .5 ohms...
Its the Power though :0) Cooked my dd doing it but man it was nice that dd impressed the hell out of me too taking it like it did. That orion didnt even get a touch warm at .5IMO if i had the money to get a 2500 i surely wouldnt chance takin it down to .5 ohms.........
Good call I thought his name looked like something i seen in the beware of scammers section.I dont help scammers....
