So, Mick P, to repeat an earlier hinted-at question:
What speakers did you install?
Your question is not too different from asking, "I just bought a car and it won't accelerate to 100 mph as fast as I want it to. Can anybody help?"
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
