I run my bxi2006d@ 1 ohm load all day every day pushing my RE XXX 15. It never gets hot, cuts out or anything. Very reliable, strong amp for the money.you want d2.. and of course you can run that hifonics on 1 ohm.. its a 1 ohm stable amp.. it might get a little hot.. but thats cause its hifonics... but don't worry just get proper venting to it and you will be fine.
