There is a fixed instal sub forum that might be more appropriate to constant voltage equipment questions.

Sorry guys, been a busy past couple of days. 

These are for professional install, not live sound.  Crown CDI1000s have been getting hot and burning out power supplies when they are in an always on install.  (Restaurants, churches with Caroline/bell systems, other businesses).  Some of these amps are using one channel for a 70v Line and one channel for an 8ohm Line.  Different inputs, different outputs. 

Iím just looking for an amp similar to that one, and the Drivecore Line might be the best for it.

not to sound condescending but why are they overheating ?? driven to limits? insufficient airflow in the rack? poor line voltage either low or high may cause power supply failures as well ?? how old out of warranty?

basically what's the root cause because these amps have been around a while in face I've put a number in some less than desirable situations and they have run for years un interrupted

What do you mean by ďAbility for one channel to be hi z and one to be low z.Ē?

Most all 2 channel amps are identical channels.

Z is used in electrical engineering. Z=Impedance

I know that. My degree is in electronics.

I asked the OP to explain his statement. We talking about amp specs, input loads, or output loads?
