Hmmm yea, well it was when I was at a car stereo shop.
I was pondering whether to install a power fuse/distribution block since I now have three independent fused power feeds coming off my battery.

So the installer guy says to get a 4 way blade fuse holder distribution block which accepts a 2/4awg input to 4 fused 4awg outputs. Wasn't sure, it be a bit expensive tho....
