bridged amplifier by simply hooking speaker between left negative the right positive?

although i could still do it better with bridging it. i dont think i have a way to invert one channel unless I bought two identical 1 to 1 ratio transformers with at least 30-500ohm resistance rated for line level signal.
then i could just invert one of the channels for example the right one
then plug my speakers in normally. invert the right speaker.
then plug a subwoofer to both speaker output positives.
and since the right channel is inverted. the subwoofer gets double the power from both speaker channels. without worrying about volume level.
That would probably cost more than it'd be worth.

What part of "each channel is already a full-bridge output" did you not understand? You can't bridge two full-bridge outputs.

Why even make this thread if you're just going to go off on nonsensical tangents about things you obviously don't understand and not take advice given to you?

well muting one channel then unmuting and muting the other with my computers control panel proves that wrong.
because it was still outputting sound even if either input was muted with the other unmuted.
as long as at least one or the other was unmuted. i'd still get sound when i played a song.
And with both unmuted. it was twice as loud. that also proves its working.

There is an easy zero-cost solution to inverting the output of one amp in your system: just connect the speaker to the other polarity of a channel.

These are class D and are already bridged - the two outputs of each channel are of opposite phase and (almost) the same level. Think that through.

Well doesnt that still mean you would get the same output level bridging it even through its already bridged? That shouldn't matter to a subwoofer. I can just apply capacitors in series with the stereo speakers to reduce the bass going to them so the sub does the work instead of the speakers.

Crown came up with a bridged bridge amp years ago, nothing new there...
