COLOSSUS DUAL MONO AMPLIFIER APPLICATIONS
BASIC APPLICATION
The Colossus Dual Mono Block amplifiers are capable of
4, 2 & 1 Ohm stereo and 4 & 2 bridged loads.
SINGLE AMP INSTALLATION PROCEDURE:
1. Connect the amp LINE INPUTS to the Radio/CD player full range or mono line out
puts with good quality RCA interconnect cables.
2. Plug in the HFR-G1 bass remote module into the amp REMOTE INPUT jack.
3. Route a 0 gauge power cable directly to the vehicle battery with an in-line 300 amp
fuse.

REMOTE LEVEL
This will allow you to operate separate subs independently (on each channel L
or R) at 4, 2 or 1 Ohm at up to 1600 watts or bridged across L & R to operate a
single sub up to 3200 watts at 4 or 2 Ohms.
Note: The amp is not capable of 1 Ohm when bridged across L & R.
The crossovers and HFR-G1 Remote Module will operate both L & R
channels simultaneously.
USING CHANNELS L & R INDEPENDENTLY
Note: You can use the Radio/CD designated mono
line output or a full range stereo line output.
For full range stereo line output, you will need an
optional "Y-Adaptor" as shown
USING CHANNELS L & R BRIDGED

4. Connect a 0 gauge ground cable directly to chassis ground with in 36" of the amp.
- Be sure to remove any paint or primer from the ground point.
- Use a nut, bolt and lock washer to secure the ground cable to the chassis ground.
5. Connect the subwoofer(s) in accordance to the diagrams below.
