Yes, it is a GeneralHP 40w with a 6pin power cable with 2 positive lines and one negative line. I would like to know if i can just run one 10 gauge wire from the battery to the 2 positive leads from the radio or do i have to run a wire for each wire for the radio from the battery?

cancel that question about the leads....i made the mistake and there are only 2 leads one positive and one negitive lol 
Thanks for all your help guys.
Thanks for all your help guys.
cool.
you had me a bit confused for a second.
if it did indeed have two positives going in to the radio, my answer would have been yes, you can just run one wire from the battery.
good luck,

So, I just got the HP40 and it came with a 12 gauge wire with 2 30amp fuses on the leads.
The cable is long enough to run to the battery and would like to try and save some money and time. I would like to just run the power cable to the battery then having to go and buy more wire. Will it be safe to just run the power cable to the battery?

It is helpful to remember that DC will have a current drop over a long piece of wire. But this will depend on the ga too. Larger ga; less drop. So how much peak current does the unit draw and how long is the wire?
Robb was wanting amperage draw. It doesn't matter now, that length of wire will work fine. Just avoid wire chaffing with your run and ensure good fusing at the battery and ground.
Looks like that length will have a little over 3% voltage drop with your supplied numbers.

If the radio has MOSFETs for final transistors; then it shouldn't draw more than 10 amps. If the panel lights on the radio get really dim when transmitting; then it might be starving for current a bit. If it does; then running 10 ga will solve it. But don't run more wire length than you need to, just enough for some comfortable wiggle room at both ends will do. Think that LC is right; because it solves the issue the first time around.
From GI Joes CB Radio/Sales:
No MOSFETs.
Getting 100w out of two 2sc1969 transistors is pure BS of the third kind - if you know what I mean.
Just not possible . . .
**EDIT**
From CBRadiosPlus/Sales:
If it does put out 100 because it has four MOSFETs; then it will need 10 ga wire - for sure.

Curious tho....why would they send a power cord long enough to reach the battery if I would have to put more wire inline?
You will notice on the sites that sell this radio that in its adverts - it is capable of doing 100w. But that doesn't mean that it will do that 100w right out of the box. More than likely that it will only do the 40w it is advertized for. In which case, 12 ga wire is fine.
IF/when the radio's output power is peaked and this radios is tuned for 100w; then it will naturally draw more than the standard 12 ga wire will handle. Because the wire is less than is needed for 100w output, the radio will only put out as much as the wire will allow.
If you did not get the radio peaked up from whatever shop you bought it from; then the 12 ga wire will probably be just fine. If it has been peaked; then expect that it will put out less with just the 12 ga wire.
MOSFETs are little workhorse devices. One can turn up their potential output power and then they will suddenly go 'snap, crackle, then pop'. Four MOSFETs should put out 100w and stay alive so long as you don't over-modulate the radio or talk for an extended period of time. A bipolar transistor - on the other hand - will have much less power output - comparatively - and only allow a small increase when peaked up.
Best to run a decent antenna and make sure the SWR is the best it can be - too - for all of the same reasons above.

Great answer thank you. It make sense now why I need to use a bigger wire. This radio has been tuned to do 115w PEP.
Now one more question since I am on the same page as you. I can run the 10 gauge wire from the battery to the stock power lead and be alright?
