why multiple runs of power/ground cable?

This is interesting. So, if I understand this correctly, I can add one length of # 4 wire to my PDX 1.1000 (currently have one # 4) to upgrade instead of using one run of a heavier guage. I assume I would just add an appropriate fuse in the new run. Is this correct?

Thumbs up

Yes.....depending how many inputs the amp has you may need to do something to merge the extra cables together but that's about it.....

Multiple cable runs

Thanks Big Red Guy. I wasn't even thinking about squishing all that wire to fit the socket, when I posted LOL. I think I can fabricate an adapter though.

remember if you built correctly (with over sized wire compared to your power needs) the extra runs advantage is negligible, but if you need more power from your front end (or the battery has more to give you) this IS an inexpensive upgrade... a second run of cable is cheaper than a battery. I would guess this would be an advantage when you are over 2k watts

Multiple wire runs

Yeah, I calculated less than 1/2 a volt loss in my single #4 run (theoretically) but I'm always interested in the opinions of more knowledgable people than myself, when it comes to safety margins etc. I'm probably OK then with a single run, since the PDX amps are pretty efficient.

# of runs used will really depend on the current draw of your amps...aswell as other things.

With your average single mono amp setup you probably wont gain a whole lot going over 2 runs total.

With a larger setup it would be dumb to think you can efficiently pull major current through one or two runs of 0 gauge wire.

Something to think about...this is the #1 street max 1-2 car (4 amps one battery) in the world for the last few years. 50 runs by my count

Basically by running multiple runs of wire, what you are trying to do is make it like the battery is right beside the amp.

wouldn't it be easier to move the battery to the back of the vehicle, if so many runs are needed?
