I know at 3 ohm bridged, the unit has never even begun to blow warm air on my equipment, and I've never had any kind of problem whatsoever. So I haven't tried what you are expecting to do, but I wouldn't hesitate to, based on my conversation with Cerwin Vega tech support.
That's what I was expecting based on prior readings, but I remember a couple doubters. I have nearly zero doubt that you're right, but it would be nice to see someone bench test the CV-5000 in order to see what they're truly made of. I'm guessing two CV-5000s would more than I would ever need for my eight 4.0 Cb. Ft. sealed 18's. I doubt I would be pushing two of them full throttle... maybe momentary blasts in movies. It's always nice to have the extra power on tap! Is the CV-5000s damping factor at 1.34 ohms a concern?
I've been at a lose of what I'd like do (it's been driving me nuts), but at least that opens up some possibilities! I've been dancing between upgrading to 2 CV-5000s powering my 8 subs or getting another EP4000 and four extra 18's... They should be about the same DB gain wise.
Two CV-5000s would be more than double the power I currently have (2 EP4000s). That should be good for a 3DB gain. Or I could go with twelve SI HT-18's and another EP4000. A 50% power increase = 1.5DB and the 50% displacement increase (co-located) = 1.5DB. That totals a 3DB gain either way.
Cost wise they should come out to about the same depending on sales. It may be even cost more going with 2 CV-5000s once I factor in the losses of selling the EP4000s second hand and paying to have my 14 gauge (15 amp) power lines upgraded. What to do.. What to do lol
If I go with twelve 18's I'll having the visual wow-factor, the extra driver reliability and slightly smoother frequency response. In the future I may do both if I can find a CV-5000 at an undeniable price.
