MrBalll Posted July 19, 2011 Report Share Posted July 19, 2011 I hope to have a 1500 Watt amp with 4 gauge power/ground on two 750 Watt subs and I was just curious about distribution blocks. Would it be worthwhile to run 1/0 gauge from the battery back to a distributor block that will split it down to two 4 gauge output connections then hook one of the 4 gauge outputs up to the amp for power and just leave the other? Would it also be worth it to run the 4 gauge ground to a similar distributor block, 1/0 to two 4 gauge, then have the 1/0 wire grounded into the rear of the vehicle? I figured the power would work OK, but wasn't sure about the ground since it's going from a small gauge to a much larger gauge. Didn't really see it grounding any better since the 4 gauge can't give enough to the 1/0 gauge wire so I just wanted to see what you guys thought about it.

Skullz Posted July 19, 2011 Report Share Posted July 19, 2011 It would be much better to have an extra battery in back to distribute from than a distribution block as it will create more resistance due to cuts in the line with terminals attached. Even if it is a small battery it will be a much better option than the distribution block would be and would allow many more wiring configurations with a battery. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
MrBalll Posted July 19, 2011 Author Report Share Posted July 19, 2011 Say I didn't have access to another battery, would I just be better off running 4 gauge both ways? I've just read it's best to run a bigger wire from battery to amps, but the biggest gauge my amp accepts is 4 so I was mainly just looking for a way to "shrink" the 1/0 down to 4 so it would fit into the amp.

nismo923 Posted July 19, 2011 Report Share Posted July 19, 2011 If all you need to do is drop the wire size from 1/0 to 4awg, you could just use a wire reducer. "If you're new. Stay away from 4000 watts please." C-Fizzy Link to comment Share on other sites More sharing options...
MrBalll Posted July 19, 2011 Author Report Share Posted July 19, 2011 Thanks, nismo. Would it be worth it to use one on the ground coming form the amp then going to a good ground? Like I said in the first post could a 4 to 1/0 reducer help anything since the 4 wouldn't produce enough for the 1/0, or at least I assume that's how it would be.

nismo923 Posted September 5, 2011 Report Share Posted September 5, 2011 With the gauge reducer, there is usually a set screw. That set screw would make contact to a lot of the little strands in the 1/0 so you would still have the same output of 1/0 it would just be able to fit into a 4 gauge hole. "If you're new.
