I plan my new house sound system around a beocenter 9500 rebuild with an ipod inside

Then, because my living room is quite big I want 4 HP.

I try that:

I plug two HP on the standard passive of the BC9500 and  plug one  MCL2P on one of the power link 1 for the two other HP

Alas each time I put the BC9500, I here a big crack as soon as the MCL2P receive power then it's work normally.

is there a way to avoid the crack ?

is it better to plug the 4 hp in parallele, 2 by 2 ? (I have only passive HP like P45, CX50, CX100....

(just for info there will be above that a 4 rooms MCL linkage with two MCL 2A and 2 MCL2AV+MCL2P)

thanks for your advise.
