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?

Dual alt

I'd have a solid battery bank, I'll be running 6 HC2400's or maybe D3100's depending on price ... but that's on about 9k RMS.

Iraggi alternators is capable of manufacturing Toyota Alternators.

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 will be pulling similar power with four 1500ds, and will be using one 130 amp alternator, and a second 220amp alty, plus a yellow-top as starter batt under hood, backed by 4 kinetik 1800's, which are 1900 amps a piece.

so total...350 amps from alty's

8450 amps from batteries. I will also be running 6 100.2's, but that power is all for over-head, so not really pulling much power there...

I hope that gives you an idea of what you need....and I'm really trying to get away with the bare minimum. $$$
