whats your electrical consist of now? big 3? power runs?

0 gauge and no big 3, cheap battery running everything in the jeep and the hc2000 running the amp

do your big 3 first... really makes a difference.

because alts are more important than batteries

BIG 3....BIG 3....BIG 3.........A chain is only as strong as its weakest link........Right now the puny factory wire on your vehicle is that weak link..........Use wire at least the SAME size as your main power wire!!!!!!!..........Oh and fuse the one between the alternator and the battery unless it is SUPER SHORT....

This doesn't really do much especially if one of your cables come loose. Both the alt and the battery are putting out power, if the cable comes loose and the fuse pops you still have a live wire...

yeah i guess your right...unless it was fused at both ends........just strap it up tight and pray it never comes loose........lol

Thanks for the info, so big 3, don't need a bigger alt? I'm changing my setup and want to get as much out of it as possibel

never said you wont need one for sure... wont really know till you do all the steps prior.... usually they go... big 3.... second smaller batt.... larger alt

I crimp my big 3 wires to hell and wrap them up with an absurd amount of electrical tape because I don't want that **** going anywhere lol

I still think fusing that wire would protect it......UNLESS it popped out of the fuse holder....then you would have a live wire.......but with the fuse in place if it came loose on the alternator end it would POP fuse and kill wire...........if it came loose on the battery end it would POP fuse and kill the wire...........does that sound logical ........... I watched a youtube tutorial a while back by Maxxsonics and they fused the wire in this manner..........

clean bare metal grounds will help a hell of a lot. dont ground to paint dont ground to rust.clean every ground point for batts and amps
