Thats really not even close w/ a stock alternator. If you had 300-400 amps of alternator to back it up that will work just fine, though We have a 200-amp and a 250-amp Excessive Amperage alternator on my friends Bronco and with one 3000D we can dip the voltage down to 11.8 volts w/ a Kinetik 2400 and a Powermaster D3100 when the vehicle is idling with the amp at full tilt. Driving around at 2000 RPM or more it does stay above battery voltage at pretty much all times. You can imagine if we had only 130-amps of alt capacity vs. 450-amps that it would quickly drop to the low 11s with only one 3000D. Thanx jacob

I have a 2003 toyota tundra and I want 2 upgrade from (1) 18" btl and an orion 2500d - to - (2) saz-3000d's and (2) 18" btls. But toyota has a patent on the wire harness to the alternator! So I don't know if I can recharge a good sized power bank efficiently with the 130 amp stock alt.. Unless I get a solar panel on my roof! Will a red top optima batt. with 2 powermaster 3100 batt. be enough power for (2) 3000d's? I know i'll end up running through some alternators every year. I just want a daily driver but I still want full power potientail? Does any body know anything about upgrading toyota electrical systems?
