I use ethier 4 AWG or 8 AWG, depending what I have in stock.

But mostly 4 AWG, and fuse it at the battery and the dist. box.


Hope this helps!

my bad, yeh your right, larger wiring from battery to box (ALWAYS!) and use whatever cable that the radio came with. If your going to use your own cable for the radio, use the same, or something bigger!

What kind of current will you be drawing?
This will determine what size of wire to use.
Add all the branch loads that will be used
at the same time. Double it (for future loads).
Use wire that is ambient temp. rated at 90 deg.
C. or better. Welding cable is good for flexability,
but not needed if stationary.

Something that I have done and still do, is to run 4 to 8 gauge in throught the firewall to one of the gold power distribution boxes. The good ones, Streetwires for example will let you put Maxi fuses in, and then I run my wires to the dist box....Of cours, fuse the wire where it ties on the the battery also.

For my jeep I used some 1/0 battery cable to run completely to the rear of the vehicle, I got a hd 30 amp resettable circuit breaker under the hood.

In the rear I got a distribution box from NAPA that is designed for semi trailers, and tied everything in back there. Every radio is also fused in the back.

This is acceptable to run a Vhf, Uhf, Lowband, and 800mhz, syntor x9000.
