Zxi8008 5 CHANNEL AMPLIFIER APPLICATIONS
5 channel discrete, one being mono low pass
You can use this configuration simply as 4 discrete full range channels, with a 5th
low pass channel. All of the crossovers are bypassed , except the LOW PASS on
channel 5. The 5 channels can also be utilized with an outboard active crossover,
or with crossovers in head units or equalizers.
Interconnect cable checklist:
Connect channel 1&2 inputs to the front output, channels 3&4 to the rear output,
and channel 5 to the mono subwoofer output of a head unit or in dash equalizer.
The LOW PASS filter on channel 5 will be in tandem with that of the source. You
can either set it to the same frequency for a steeper rolloff, or set it to a higher
frequency to minimize it's effect. By the same reasoning, you could switch
channels 1,2,3&4 high pass crossovers in for steeper high pass slopes.

3 or 4 channel discrete, one being mono low pass
We will use the same basic setup as above to illustrate a 3 channel arrangement,
by mono bridging the stereo channel pairs 1&2, 3&4. For a 4 channel setup, mono
bridge only one set.
Interconnect cable checklist:
- Use 2 Y-adapters RCA cables, one for channels 1&2, and the second for channels
3&4, to create 2 inputs for channels 1,2,3&4 only, as shown.
- Connect the positive terminal of channels 1&2 mono speaker to channel 1+, and
its negative terminal to channel 2-. Connect the positive terminal of channels 3&4
mono speaker to channel 3+, and its negative terminal to channel 4-.

- CH 3 / 4 HIGH PASS: N/A
- CH 3 / 4 LOW PASS: N/A
- CH 5 LOW PASS: 100 Hz
Please note that these frequency points are suggestions only. Refer to the
loudspeaker manufacturer specifications and the section "Setting up systems

Level control checklist:
- Refer to the section "Setting up systems after installation for best performance"
Minimum final loudspeaker impedances:
- 2 ohm per channel
- Channel 5 is a true single channel, and as such is not bridgeable.
Minimum final loudspeaker impedances:
- 2 ohm per channel in stereo mode
- 4 ohm per mono bridged pair
- 2 ohm on channel 5
