I have my 3500 @.5 daily with no issues, dimming or hardly any voltage drop. 200a alt xs d3400 under hood and 1 d3100 in back. on 4 15's it is giving me plenty of power. I am quite impressed honestly. just a 1/4 gain, no boost and it is pretty violent at higher levels. try it and see. I thought i would've had to at least have another 3100 in back but now i don't see where i need it.
