AMPLIFIERS
INSTALLATION CONTINUED
POWER:
Connect a wire directly to the vehicle’s positive battery
terminal, installing an appropriate fuse holder within 18 inches of the
battery. Route the wire to the amplifier’s location, connecting it to
the amplifier’s positive terminal (+12V). Be sure to use appropriate
grommets whenever routing the wires through the firewall or other sheet
metal. After routing and connecting this wire, you may install the fuse
into the fuse holder near the battery.
REMOTE:
Connect the amplifier’s remote (Rem) terminal to either the
source unit’s remote turn-on lead, or an alternate switched 12V+ source
using a minimum of 18 gauge wire.
STEP 3: SIGNAL CONNECTIONS
The MVP amplifiers have been designed to accept both low-level “RCA”
inputs, as well as high-level speaker inputs through the included four/
eight-pin plug.
LOW-LEVEL RCA INPUTS:
To use the low-level RCA inputs, connect
a high-quality RCA cable from the preamp outputs of the source unit to
the RCA inputs on the amplifier. For the clearest signal, we recommend
using an NVX shielded “noise-rejecting” twisted RCA cable.
HIGH-LEVEL SPEAKER INPUTS:
To use the high-level speaker
inputs, connect each of the wires coming from the included connector
to the corresponding speaker output wires from the factory source unit.
Take care to match the polarity and channel of each wire. Once the
speaker wires have been spliced, plug the connector into the amplifier.
STEP 4: SUBWOOFER & SPEAKER CONNECTIONS
Once you’ve made the power, ground, remote, and signal connection
for the amplifier, you are ready to connect the speakers or subwoofer(s).
Simply connect the speaker wire to the terminals of the corresponding
speaker or subwoofer. For the best results, we recommend using NVX
speaker wire with a minimum size of 16 gauge.
