TXi4408 / TXi6408 / 4 CHANNEL AMPLIFIER APPLICATIONS
4 CHANNEL FULL RANGE SYSTEM
Here we show how to use the 4 channel amplifiers as straightforward discrete 4 channel
full range units.
Interconnect cable checklist:
- Connect the four inputs of the amplifier to a Radio/CD with quality RCA cables.
Switch setting checklist:
- 1/2CH X-OVER: FULL
- 3/4CH X-OVER: FULL
Crossover frequency control checklist:

2 or 3 CHANNEL FULL RANGE SYSTEM
Here we show how to use the 4 channel amplifiers as full range 2 or 3 channel units by
taking advantage of the mono bridging capability of all Hifonics amplifiers.
The following example shows how to create a 3 channel system by mono bridging
channel pair 3 / 4. In order to create a 2 channel system, simply follow the example to
also mono bridge channel pair 1 / 2.
Interconnect cable checklist:
- Connect the inputs of channel pair 1/2 to a suitable stereo source, e.g. a head unit
with good quality RCA cables.
- A MONO signal source is required to bridge channel pair 3/4, such as would be
available from the mono sub bass output of an active crossover, whether standalone,
or built into a head unit or equalizer.
Important: Do not be tempted to connect the hot, or positive outputs, from any source
together to obtain a mono signal, as this could very well damage the output stage of
that source.
- It is necessary to feed the SAME signal to both left and right inputs via a Y-adapter
RCA cable.
- Connect the mono speaker positive terminal to the LEFT +, and its negative terminal
to RIGHT - as shown.

TIP: If you are using the mono sub bass output of an active crossover, there is nothing
wrong with switching in the low pass filter in these amplifiers for a steeper low pass
rolloff.
