COLOSSUS DUAL MONO BLOCK AMPLIFIER APPLICATIONS
BASIC APPLICATION
3
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
4. Connect a 0 gauge ground cable directly to chassis ground with in 36” of the amp.
with good quality RCA interconnect cables.
- Be sure to remove any paint or primer from the ground point.
2. Plug in the HFR-G1 bass remote module into the amp REMOTE INPUT jack.
- Use a nut, bolt and lock washer to secure the ground cable to the chassis ground.
3. Route a 0 gauge power cable directly to the vehicle battery with an in-line 300 amp fuse.
5. Connect the subwoofer(s) in accordance to the diagrams below.
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.
