Use conventional stranded copper wire for all connections. Tinned Copper MXA marine grade wire is

recommended for corrosion resistance in powersports and marine applications. Finish the ends of the wires at the

amp and vehicle with proper size terminals. Poorly made connections and/or inadequate wire size will generate

excessive heat and may lead to equipment failure.

12 Volt + Connection

make the 12V+ connection directly at the positive battery post using the proper wire size and fuse listed below, The

fuse should be installed within 18" of the battery for standard applications and withing 7" of the battery for marine

applications*. This fuse is vital to protecting the vehicle from damage in the case of a dead short. The fuse value at

the battery should be at least equal to the total fuse value of all the ampliﬁers being used.

Ground Connection:

For marine applications connect the ground to the negative battery terminal. For non-marine applications ground

connection directly to the chassis of the vehicle as close to the amp as possible. Make sure this connection is made

with the same wire size as used for the 12 volt connection. Ensure that all dirt, grease, paint and coatings are

removed prior to attaching the ground wire to chassis.

Remote Turn On

Remote turn on should be connected to the source unit's remote turn on lead. 18 gauge wire should be ran from

the remote turn on lead on your source unit to the terminal labeled REM on your ampliﬁer.

*NOTE: Seven inches is the standard distance under U.S. Coast Guard CFR33 for placement of fuses or

breakers as required by law for new boat manufacturing. It is recommended that you adhere to this standard

in an installation. Not adhering to this regulation puts the safety of boat passengers at risk in the event of a

power wire shirt circuit.
