Broke_Audio_Addict Posted November 8, 2015 Report Share Posted November 8, 2015 My 270 did a hair under 200 amps (like 198)at idle loaded down. In that truck I would consider an independent charging system for your system and I would go with the biggest hairpin alt you can get. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

everybodyknowme Posted November 8, 2015 Report Share Posted November 8, 2015 250amp minimum will work with the current batteries you have but the cost difference for the 270 should be minimum so I would get that. Like others say get a hairpin if your looking for increased idle amps but a conventional will work. Yes it will cost a bit more but will be worth it and the dual alt bracket for you truck would be the best way to go for conventional or hairpin BTW: If you do decide to get the conventional 250a you'll see around 140a at idle hot vs around 180a for hairpin Link to comment Share on other sites More sharing options...
Mack187Murder Posted November 8, 2015 Author Report Share Posted November 8, 2015 Awesome guys thanks for replies. So I should be fine switching out 140 for a 270 conventional. Or your saying I should just add the 270 to my 140 and that will be even better? Does the different amperage create problems or is it a non issue? .

mcfalcon Posted November 8, 2015 Report Share Posted November 8, 2015 Adding it would be better imo. Still learning but have started gathering. Link to comment Share on other sites More sharing options...

mcfalcon Posted November 8, 2015 Report Share Posted November 8, 2015 So 1 270 conventional and 2 d3400s is enough for 5k? Still learning but have started gathering. Link to comment Share on other sites More sharing options...
