i have a sony str-dn610 receiver
i have a paradigm cc450 center speaker
the specs say 4 Ohm/8 Ohm Switching : No(8 Ohm only)
can i bridge the center speaker and still run it to the center speaker connection to the amp or will this destroy my amp?
also on the paradigm cc450 the gold plates( idont know what they are called) that are under neath the terminals are missing is this bad?

Home receivers are not built to bridge amp channels. That is combining the power of
2 channels to 1 (mono) inside the amp. Most car amplifiers will bridge amp channels,
but not receivers.

The speakers that have dual binding posts are meant to be bi-amplified.
Not the same as bridging. If you are running only 1 set of speaker wires
then the jumper bar needs to be in place. Otherwise only your tweeter or
midrange driver is playing. Don't do this. At minimum connect between
same colored binding posts or run a set of wires from the same connection
on the receiver to each binding post on speaker.

Some receivers will do bi-amping. This would be labeled on receiver at binding
post area and in manual. This has to be set in the receiver setup software.
It doesn't really make a noticeable difference to bi-amp a center speaker.
If you did bi-amp that speaker, each speaker binding post needs to be
connected to specific receiver outputs. Don't bother. Just immediately turn off
receiver and jump your posts on the speaker back together. Rerun the room
correction software (audyssey) after connecting speakers properly.
