On a 2 channel amp that I plan on bridging, do I need BOTH rca ins?
I have 2 of the same amp that I want to use for the fronts. I also have 2 sets of components going up front.
The amp is 80w x2 @ 4ohm
110w x2 @ 2ohm
or 220w x1 @ 2ohm. Both sets of components are good for over 120watts, so this is what im planning on doing
Amp #1 will control the left speakers, I will feed it a left channel input and then bridge both left speakers to give me a 2ohm load, and then itll give it 110w each. Rather than wire all 4 speakers off 1 amp I would only get 55w each (where only using 2 would be 80w) so I dont want that.
Basically my question is: if I have a left and right rca, can I put the left one into one amp and not need another connection? Meaning left rca will go to 1 amp and the right rca will go to the other amp. Can I just leave the other rca open or does it need it to be able to "merge" the left and right to give it a bridged output? Its a 2 channel amp is the only reason im asking, I know its fine on a mono amp with 2rca inputs and only using 1.
