I've read that Tripath amps invert polarity.Do you change the speaker connection ( + to - , - to + ) on one or both speakers ?

If you are refering to the scheme commonly used in car stereo amplifiers.....

Most car stereo amplifers have one channel inverted.

The inverted channel has it's speaker terminals marked so that the '+' terminal is actually ground and the '-' terminal is the amplifier output.

So you don't need to worry about inverting polarity of the speaker because the speaker terminals are marked appropriately.

No polarity inversion is necessary for bridging since one channel is already inverted.

You just connect the speaker to the '+' terminal of the non-inverting channel and the '-' terminal of the inverting channel.

All you need to do is use a 'Y' adapter to connect both inputs together if the amplifier does not have a switch which does this for you.

Sorry Daryl,none of that applies in this situation.I'm refering to Tripath Amps(Trends,Pop Pulse or King Rex) that are used in home audio setups.I'm pretty sure I've read somewhere on the internet that speaker connections have to be reversed when using these amps.

You can swith the speaker leads on both if you like.  You will know if you did just one since you will hear the effects immediately.

Elementry, my dear Irwin,

You asked a rather non specific question about a Tripath based amp. Daryl gave you a valid explanation. The configuration he described is also used in the CarverPro ZRxxx series of tripath based amplifiers, for the very specific reasons he mentioned, like the ability to operate as a stereo amplifier and with minimal hassle, a bridged mono amplifier.
Those specific amps you now mention are already bridged amps, by Tripaths specific implementation of that feature in those chip's architecture, single rail BTL (Bridge Tied Load) amps [use Google]. For anyone to produce an inverting (power) amplifier from this architecture, it would be confirmation that they are  , unless....
the Tripath BTL output stage is preceded by a simple inverting voltage gain stage, typically a tube, but it could also be a discrete FET or bipolar transistor stage. As that preceeding stage is inverting, the following Tripath output would be also configured as inverting. Who says 2 wrongs can't make a right?

FWIW,
Paul
