I would not even try. .5 is pushing it. even thou it claims .5, that is like the absolute minimum. and even that is iffy, depending on how its setup and what electical is backing it up. For that you would want a H/O alt and 3 batteries IMO.I have a Soundstream 2600.1 the half ohm stable version. If my electrical is strong and I can keep my voltage up. Think the amp can take .35 ohm???
its your risk. everything is a factor.I don't have the H/O yet but I do have three runs of 0 gauge, a crescendo battery under the hood and two 2600 farad cap banks in the back... not sure if that is enough. also im not super familiar with box rise. will that play a factor??
