Hi!
Building a pair of 18"-subs for my 250 ti's put me in rather a big problem. Here's the background:
My pre-amp has both balanced and unbalanced outputs.
My active crossover has balanced in and outputs.
My 250 ti amp has unbalanced inputs.
My subs amp has balanced inputs.

My AC wall outlet has no ground connection.

Is there then any meaning in going balanced from the pre-amp to the crossover and then to the sub amp and unbalanced just from the network to the 250 ti amp, or should I just go unbalanced all the way, and is it really possible to go balanced at all when there is no ground wire in my wall outlet?

Please excuse my bad english and please help me out!

Thanks!
