OK, i just started using this hartke lh500 and eden d210xlt and had a few questions. reading the owners manual it says it puts out 350 watts to a 8ohm cab and 500 watts to a 4ohm cab. my eden has dual voice coils and can do either 4 or 8ohms but there is no switch like on some other cabs. so how do i know how much my amp is putting out? I have a gig coming up soon and don't want to toast these expensive eden drivers that are only rated to 350 watts. I intend on building a second cab with a 15 or a 12 in it soon that I'll run at 4 ohms to make sure that i get every last drop of power from this thing. but for now i just need to know how far i can push it.
