First of all, any testomonials about this amp?

I have 2 400W RMS, 600W max, 4ohm 10" Kenwood subs. They're sorta old, probably from the 90s so I think they're single voice coils.

if you look at the specs of the amp here:

it says that bridged, it can do 400W x 2, which would be perfect for my subs right? however it says that it's stable into 4 ohms in mono mode... my subs are 4 ohms, but I also remember reading somewhere that when bridged, a 4 ohm load reads as 2 ohms to the amplifier. can someone verify this? would the amp be stable running 400W monoi bridged into 2 separate 4ohm subs?
