[QUOTE="eztrez2013, post: 8275846, member: 654939"] I have a 2014 Infinity Q50S AWD. The car has a stock 150 amp alternator. The resting voltage varies greatly. I can drive down a busy street and at the first red light I'm resting at 13.6V. The next red light I'm resting at 12.6V and the next red light I'm resting at 14V. So on and so forth, It doesn't seem to matter whether I'm full tilt or music off. When at full tilt I see up to a .5 voltage drop with a Fosgate T1500bdcp at 1 Ohm. Problem is the drop is always about .5 whether I'm at 12.6, 13 or 14.4. What causes this??? AND What can I do to regulate and keep the voltage on the higher end. It's driving me crazy always checking my meter to see if I'm safe to rail on it.. I'm assuming it being regulated by a module of some sort but what's the get-around? Someone help...Not sure if it matters or not..But big 3 (plus a couple extra grounds in 1/0) AGM is front and a big 140 AH AGM in back...Need some help... Thanks in advance [/QUOTE]
