Mcintosh MC4000M input sensitivity?

Hello all, this is my first post and I had a good question. I recently purchased a McIntosh MC4000M 6 channel amplifier from a friend and I called McIntosh and spoke to one of their techs and he said that it would be ok to use this amp with the 8 volt pre-amp output of an Eclipse CD8455 Headunit. This was information I found out before I commited to purchasing this amp from my friend. I ordered an owner's manual for the amplifier and it says that input sensitivity is .3- 2 volts. Will the 8 volt from my Eclipse headunit work with it or do I have to find a different amp solution? Thanks. -Jason

I have MB Quart QSD 216's going in the front, I was planning on bi-amping these and using all 4 100 watt channels through the Q crossover to gain full adjustability to tone down the tweeter a little and I think that I am going to be running my Eclipse 8455 with the 3-way output setting. For a sub, I am thinking about an IDQ 10" or 12" unless I can get away with using each of the 300 watt x 1 sections of my amp to each voice coil of a dual 4 ohm v.c. sub. -Jason

Oh yea, it's going into a 2006 Subaru Impreza WRX Wagon. I had the Q's in a 2004 WRX Sedan with a Memphis 150 x 2 amp previously off of an Alpine 9835. -Jason
