Citation 7.1 CUTS out, do I need More Power?


I have a 7.1 which I am using in a bridged mode,
450 x 2 @8ohms and at a very loud, close to clipping probably, the amp will cut off, then back in, then off, then back in, and so on. When I turn the volume down,
it is fine. Is this some type of internal circuit to prevent damage to the amp/speaker?

Anyone?

Also, does this mean I will need more power for the volumes I am listening at?

Thanks,

You are better off not bridging if the 10Ts are of 4Ohm nominal. The amp ends up seeing half of that load in bridged mode. Stability is also an issue in bridged mode. That said, the Citation 7.1 is supposedly stable down to 2 ohm and can still deliver down to 1 ohm. It's available power retracts when the load is 1ohm and will probably shut down for less. Given all this, I'm curious to know at what SPL level this is happening, and how the SPL isn't affecting you.

P.S. How do you like the 7.1 compared to the rest of the amps that you tried? Also, I have some factory power specs for the 7.1 that I found on the digitaltheater forum. Let me know if you want it.
Dan,

I emailed you the spec. Hope it helps. By this spec, in bridged mode, the drivers of 10Ts will probably reach their mechanical limit/extension before your 7.1 runs out of gas.
