brent379 Posted May 15, 2012 Author Report Share Posted May 15, 2012 I would hope I'd be ok!! I was running 1300rms in my 94 Dakota 3.9 with stock battery and alternator with no upgrades wat so ever and it didn't do to bad...and only 4 gauge And yes all DIESEL trucks come with two batts.....but mine is just the 6.0l gas so mine only has one batt.
