Distro block or 2 Power Leads?

I have a 2 amps 150 (2 channel) and 120 (4 channel), My question is, Would running 2 power leads from the battery ok to do instead of using a distribution block? I know I would have to use a fuse on both lines. But is using a distribution fuse block really neccessary? thanks

1. Yes.  And 2. No it's not, as long as both wires are properly fused for the wire rating.

This is one amp per wire, so as long as the wires are plenty large enough for max amp draw it's fine to do.  And, there is resistance added any time a connection is made such as a disto block, or the second fuse holder and fuse, too.  That would be neglible as well.  Compared to the resistance that the audio has through chassis ground, the points of resistance in the power line don't count for much.

ok so besides the extra material there wouldn't be any blown amps, speakers and or car turning into  a big blazing ball of flame down the freeway...and thank you so much for the info
