I have an 04 Impala SS 3.8L that came with the 9c1 125amp alternator that does 65-70amps at idle.
My Current Electrical System Consists of;
PowerBastards 240amp Alt
Optima G34/78 Yellowtop (55ah)
ZZP Stg.1 Volt Booster (+0.6v)
Big 6 (Big 3xDouble runs)
One 18ft Monster 1/0 +Pos
2 Stinger SPV70 (70ah) batteries in trunk
I was able to run my DD M3a (Gain 75%/No Bassboost) @ 1ohm crankin out 3000wrms to 2 15" Memphis CM Mojo and would hold 14.4v-14.9v while crusin at any speed. Full tilt @ Idle would hold 14.1v to 13.6v for about a full minute but after about 90sec on some crucial decaf, it would dip sometimes as low as 12.5v
I then sold 1 SPV70 and was able to run the M3a @2ohm and was similar to 2 batteries at 1ohm but would hold it longer before it dips into the 12's.
Well now I am looking to part ways with my baby but only in search of her older brother M4a which leads me to my question..Obviously what I have right now won't cut it, but If I was able to hold 3k pretty good with 2 Stinger SPV70 (70ah) batteries...tell me what you think about what is going to be my new setup..
Beefin up for the M4a;
DC Power 270xp/320xp alternator
2nd 1/0 + Run (Main to Secondary Batteries)
1st 1/0 - Run (Main to Secondary batteries)
TWO (2) XS Power XP3000 (120ah ea/240ah total)
So do you think a DC Power 270xp or 320xp alternator, 2 XS Power XP3000(120ah) batteries, and 2 extra runs from main to secondary batteries be sufficent enough for an M4a?
