4. Fuses:
• Replace only with fuses of the same amperage:
0
МА704: ЗОА
0
МА4505:ЗОА
5. Power lnput Gonnectors:
• Power: Run power wire from the + 12V input to the positive terminal of the vehicle's battery. lnstall ап appropriate fuse holder and fuse (БОА minimum
оп МА 704, 105д to 1 ООА minimum оп Мд4505) within 18" (457mm) of the battery. Make sure the wire is not damaged or pinched during installation.
lnstall protective grommets when routing wires through the bulkhead or other sheet metal. Use larger-gauge wiring for longer runs.

Мд704 minimum wire size: 8 gauge

МА4505 minimum wire size: 4 gauge
• Ground: Run а wire (the same gauge as the power wire) from the GND input to the battery's negative terminal, using а ring terminal.
Note: А larger gauge wire may Ье needed when the amplifier is not located near the battery. Where applicaЫe, remove апу paint from the vehicle
chassis and connect with а bolt and star washer (below the ring terminal) for а secure connection.
• Remote: Connect а 20-gauge wire from the "Remote Out" lead of the source unit to the REM input. This lead turns the amplifier оп when
using low-level input signals.
6. Front and rear inputs and outputs (RGA):
• lf your source unit offers preamp outputs, connect to the FRONT, REAR, and/or SUB inputs using RCA patch саЫеs.
• То connect а second amp directly to the МА704 amplifier, run а patch саЫе from the PRE OUT outputs to the second amp's preamp inputs.
lf your audio system's head unit does not have line-level outputs:
Use the supplied bare wire-to-RCA adapters to connect the amplifier's inputs to either the front or the rear speaker outputs of your саг audio
system's head unit (splice crimps not included).
Use а small Phillips screwdriver to loosen the adapter's set screws and insert the speaker wires into the holes оп the back of the adapter.
Tighten the set screws to secure the wires.
