Should distribution block fuses be used?!?
Was just on Crutchfield.com and read this:
Q: Do I need a separate fuse block too?
A: A safe system will have the right fuses installed at each amplifier and also on the power cable by the battery. But if you've ever taken a peek at some competition-style car audio systems, you may have noticed fuses at a third location — in a fuse block by the components. Sure this hardware looks good, but is it necessary?
Unless your amplifiers are among the few that don't come with fuses installed, the answer is no. The reason you see these "redundant" fuses is that in the early days of car audio competition, amplifiers frequently didn't include their own fuses, or if they did, often hid them behind panels that were hard to get to, especially in the heat of competition.
Today, the use of such fuse blocks is largely a matter of style. But that's OK — looking cool definitely counts. In the world of car audio, it's a close third, right behind being safe and sounding great.
I currently have a fused distribution block getting 4ga wire from my battery (fused at the battery) and sending out two 8ga wires to power my amp and invertor. Though both components have onboard fuses, it was my understanding that the power wire coming form the distr. block to the components needed to be fused in order to prevent fire in the car. Should I stick with getting fuses for the distr. block or will they be a waste of time as the pasted text indicates?
Thanks in advance for the help.
