Hello Disconnect the speaker connections and switch ON the set. Set a multimeter to measure volts, and measure the voltage acorss the shorted speker terminals at amplifier end. There should not be any voltage at all. That is, the voltage measures at the speaker terminals must be approximately equal to Zero. If hter shows any voltage, make sure that the output amplifier to that side is shorted. never connect an other speaker, even for checking. It will also burn out. Connect speaker to this channel, only after rectifying the fault, if any.
is the difference between bi-wiring and bi-amping?
Bi-wiring is using the same power source (amplifier) but
connecting that power source to a woofer and a
midrange/tweeter on a
Bi-amping is using two separate power sources (amplifiers)
connecting one amplifier to a woofer and the other amplifier
midrange/tweeter on a speaker.
How do I bi-wire?
Your speaker must have two separate positive and negative
connections (one set for the woofer and one set for the
midrange/tweeter). Connect one wire between the positive

The illustration in the manual I found at retrevo.com isn't detailed enough to show the axial connection option, which would normally accept a banana plug inserted straight in if the opening is conductive and about 4mm wide. I suspect it is as they mention a "variety of wire connectors".
Their only illustrated example show bares wire ends inserted into a small hole drilled through the termial post and the red or black plastic piece tightened down to secure it.
WIRING THE SYSTEM
IMPORTANT: Make sure all equipment is turned off before making any connections.
For speaker connections, use a minimum #16-gauge speaker wire with polarity coding.The side of the wire with a ridge or other coding is usually considered positive polarity (i.e., +).
NOTE: If desired, consult your local Infinity dealer about speaker wire and connection options.
The speakers have coded terminals that accept a variety of wire connectors. The most common connection is shown in Figure 5.
To ensure proper polarity, connect each + terminal on the back of the amplifier or receiver to the respective + (red) terminal on each speaker, as shown in Figure 6. Connect the – (black) terminals in a similar way.
See the owner’s guides that were included with your amplifier, receiver and television to confirm connection procedures.
IMPORTANT: Do not reverse polarities (i.e., + to – or – to +) when making connections. Doing so will cause poor imaging and diminished bass response.
Place the amp where you are going to permanently mount it. The cap. should be as close to the amp as possible. Run the positive cable from the pos. terminal of the battery to the pos. terminal on the cap. Then from the cap's pos.terminal run a cable to the pos. terminal on the amp. Dont install the fuse into the fuse holder just yet. Make sure you place the fuse holder at most 10 inches or closer to the battery. Find a good ground point to run the negative cable to the cap. make this one as short as posible, use any good solid metal part of the car's chassis or bolt that runs into the body. Run another ground cable from that piont or nearby point to the amp's negative terminal. run the rca cables from the back of the head unit outputs to the inputs on the amp. Then run the small gauge remote wire from the amp remote output from the head unit to the remote turn-on terminal on the amp. run your speaker wires from your amp to your speakers. Install the fuse, it will spark a tiny bit when installed, its normal thats just your stiff cap and the caps inside your apm charging. Usually you charge the cap before you introduce it into the system to prevent that spark but a cap that size doesn't create a huge spark. good luck
sometimes the protection circuit will enable because of a bad speaker i would suggest taking the load off of it by removing the speaker wires and turning it back on. if it stays on take an ohm meter and check the speakers should be between 2-4 ohms load.
Sounds like classic dry joint on speaker terminal ROTELS are well known for it,if you can use a soldering iron or know someone who can resolder the pins where these terminals are connected,always make sure amp is unplugged from wall socket before ...
Make shure your speaker wiring is solid hookup to amp and spekers (NO CROSSED WIRING). Also make shure speakers are not wired in parallel or the speaker impeadance will be to low and amp will kick out.Turn speakers off then hook up headphones and crank up volume then see if amp kicks out.If it does you have an internal overload and needs serviced. If it playes ok then you must have speaker problems or wiring.
