It depends on the size of amps you are using. Look at stinger products. They make good kits. You can buy there stuff on ebay at a good price. That is where I got some of my stuff. I didn't buy a kit. I bought some 0ga wire. I put a fuse holder by the battery, then ran the wire to the back of the cab. From there I hooked the other end of the 0ga into a fused block. The fuse block I used is called a midi. It has a 0ga input and two 4ga outputs. I used the 4ga to go to the amps. I also used stinger rca cables and speaker wire.
