Re: Why do my speakers sound like *****?
Don't run a passive network without all the drivers it was meant to have connected. You could damage your amp as that portion of the passive will appear to the amp to be a dead short.
That aside, did you have the amp bridged to the whole shebang before when you were using the whole passive setup? If so that is why you don't have the midbass performance that you had before, you have maybe a 1/3 of the power going to the midbasses.
If I were you, I would just run the passive network and the extra power of the bridged channels.
Artificial Intelligence is no match for Natural Stupidity.
Never underestimate the power of stupid people in large numbers.
Life's tough...it's even tougher when you're stupid.
