[QUOTE="llebcire, post: 8722134, member: 671377"] Yes and no - depends on the length. Ideally you would have the same gauge for both, but the size is dependent on the length of the run. As the wire gets longer the resistance increases therefore the gauge also needs to increase as you can see from the chart - longer runs need larger wire to carry the same current. Think of it this way - inside the amp, for the short runs between the terminal blocks and power supply, they rarely use large wire as the runs are so short. Long story short - use 4 gauge if you have it however if the run is short (<2 feet) there won't be a difference using 8 gauge. Ensure your connections are solid, grounded to bare metal, etc. -Eric [/QUOTE]
