Full Performance
10 gauge 0.04 V/ft 5 ft.
8 gauge 0.025 V/ft 8 ft.
6 gauge 0.015 V/ft 12 ft.
4 gauge 0.01 V/ft 20 ft.
For best performance the voltage drop at maximum power in the high current power and ground leads
should be limited to a 0.2 volt maximum. Refer to the Interconnections section for information on the
wiring and fuse requirements of this amplifier.
Fuse Holder Installation
Included in the wire harness bag are 3 fuses and fuse holders. Install these fuse holders at the battery
or electrical system voltage source after the power harness wires have been routed to their final
destinations.
The cartridge type low current fuse holder is for the red low current power lead. Use 3AG type
(automotive glass) 5 ampere fast blow fuses for this lead. This holder is usually shipped with the lead
connected to both sides of the holder. Cut the lead in the middle and remove 1/2 inch of insulation.
Connect the short side of the holder (without a spring) to the lead from the amplifier. If a remote
on/off switch is used it should be installed between this fuse and the amplifer. Connect the long side of
the holder to an ignition key switched source or to a positive battery lead. A switched source can
usually be obtained from a fuse in the fuse box (radio or accessory) or a convenient wire under the
dash. Use wire nuts or solder and tape all connections.
The plug-in fuse holders and 30 ampere fuses are for the red high current power leads. Do not insert
any fuses until wiring is complete. These holders have Teflon coated 12 gauge leads. They can be
used for any size of power lead because their length is short. Solder
one lead of each holder to one of
the lugs supplied. Install the lugs over the starter solenoid post that connects to the battery or over the
bolt that secures the positive battery terminal. Use a separate nut to secure the lugs to avoid disturbing
battery connections if possible.
Connect the other lead of each 30 ampere fuse holders to the heavy gauge power leads by stripping,
twisting, and then soldering the leads together. Bare wires should be wrapped with several layers of
electrical tape. Be sure to dress all amplifier leads so that they are not exposed to sharp edges, high
temperatures, or moving parts. After wiring is completed install the fuses.
Auxiliary Battery Installation
If possible, avoid the use of an auxiliary storage battery. Ameritron does not assume any liability and
does not recommend the use of an auxiliary battery. The individual installation is left entirely up to the
installer. The following suggestions will increase the safety of the installation.
The positive lead that connects the auxiliary battery to the main battery should be fused at both ends
with automotive type fuse links rated at 75 to 100 amperes. The positive power cable that connects the
batteries should be number 6 AWG automotive type cable. The negative return can usually be made
through the chassis of the vehicle.
