In the garage sale section I have a Parasound a23+ up for sale that will fit the bill. It is very detailed, reliable, has killer bass and is easy on the ears up top. PM me if interested.
I wouldnt say that. These are 3 dB hot up top out of the box. I prefer the sound of them that way. The balance is more to my liking. I have two GIANT subs right now.. Zero issues in the bass department and I listen regularly with the subs off as well.
Don't know exactly what your Inputs and outputs are, but in my case, I have successfully used custom XLR Y cables with good results. No noise. As long as one amp is off and the other is on, there were no issues at all.
