I am installing the new Btech GMRS 50PRO in my truck. A general rule of thumb is to install fuses about 6 inches from the connection to the battery. However, the fuses on the radio I got come hardwired six inches from the radio and not on the extended cable it comes with. My question, is do I add extra fuses in line next to the battery on top of the fuses that come with the unit, or do I just use the fuses that come with the unit itself, despite them being so far away from the car battery?
