this is actually the 2 channel version so it makes its power bridged at 2 ohms but yes very underrated
i have the mono version in my temp setup and i clamp 1000 with a rise to 2.33ohms at 14.4 volts yeasterday
the t-500bd i have had a 1000+ on the birthsheet that cam from rockford and ive never had a problem out of it before it got put in the garage for more power
i dont know nothing about the mb though
i have a 05 and it peaked at 49 with one setup and 44 with the current on so i bet it will be in the 45-50 hz range but you will need to meter it to find out
i love those treo motors wish i had a use for them (i just saw them on caco)
Wish you were closer I have a friend with the same car and I but I could talk him into buying the whole setup just because tou have the same car and I love those subs
