"how to bi-wire if my power amplifier has only 1 set of output connection?" - jack368

Most do - most biwire cables have 1 connection for the amp end and 2 for the speaker end.

"can I use 2 different brands of cables and clamp plus-plus and minus -minus on my power amplifier?"

Yes

"most importantly will it damage my power amplifier?"

No

Hi,
I need some recommendation from you guys on what is the best cable to use for bass unit for vr4jr bi-wire configuration?
for mid-hi unit I am using the analysis plus solo crystal 8 speaker cables.
hope to hear from you soon.
thank you.

The vr4jr doesn't sounds good when using data link is because the signal has to travel a longer way to reach the tweeter module, bass and treble are not functioning at the same speed.

"the signal has to travel a longer way to reach the tweeter module"

When not bi-wiring the VR4JR, don't connect your cables to the bass cabinet. You should connect the speaker cables to the monitor posts and pass signal to the bass drivers using the datalink and jumpers across the lower posts. This might be why some people see poor results when not bi wiring.

I've had it all four ways and bi amping really is the best thing with these speakers. It adds an astounding depth and authority that I never heard when single amped and single wired.

If you are using a single bi-wire connection, I can teach you another way of hooking up your speakers. these configuration only requires an additional pair of short jumper wires. basically to match the types of bass you desire.
Its a bit difficult to explain here, if you are interestd to know you can forward me your email address and a picture will send to you with the soonest possible.
