XXV MAXXIMUS DUAL MONO BLOCK AMPLIFIER APPLICATIONS
BASIC APPLICATION
11
The 2 channel mono amplifiers are capable of 4, 2 & 1 Ohm loads wired channels 1 & 2
independent as shown below or 4 or 2 Ohms wired mono bridged shown below.
The XXV-MAXXIMUS has two 5000 watt D-Class channels built-in labeled Subwoofer 1
& Subwoofer 2 on the end panel.
SINGLE AMP INSTALLATION PROCEDURE:
1. Connect the amp LINE INPUTS to the Radio/CD player full range or mono line out puts with good
4. Connect two 0 gauge ground cables directly to chassis ground with in 36” of the amp.
quality RCA interconnect cables.
- Be sure to remove any paint or primer from the ground point.
2. Plug in the XXVR-1 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 two 0 gauge power cables 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 1 or 2) at 4, 2 or
1 Ohm at up to 5000 watts or bridged across 1& 2 to operate a single sub up to 10000 watts
at 4 or 2 Ohms.
Note: The amp is not capable of 1 Ohm when bridged across 1 & 2.
The crossovers and XXVR-1 Bass Remote Module will operate both 1 & 2 channels
simultaneously.
