tbeats Posted July 2, 2016 Report Share Posted July 2, 2016 Hi so on this install the amp is a sundown scv 1500d that has a 4 gauge input and I have two xs power xp750's in the rear at the amp all running on the same knukonceptz 4 gauge ofc, my ground on the batteries is a knukonceptz 1/0 gauge ofc though. I had always heard a larger ground wouldn't hurt. Question is with the batteries added with the draw for theme should I run a 1/0 power to replace the 4 gauge to the rear battery? My front battery is a xs power d4800 and a 240 amp alt. Link to comment Share on other sites More sharing options...

DLHgn Posted July 2, 2016 Report Share Posted July 2, 2016 It wouldn't hurt to upgrade but I couldn't tell you if it is necessary. Link to comment Share on other sites More sharing options...
Wasteland_Audio Posted July 2, 2016 Report Share Posted July 2, 2016 I believe toolmaker makes 1/0 to 4ga reducers. It never hurts to run the biggest wire you can, plus you may get a little more output using 1/0 because it will carry current much more efficiently over that distance.
