High Output Alternator for 3rd Gen Tacoma (350 amps+)

your easiest option is something like this. with 4 DD 6.5" I'll try to get picks on mine with the 2 DC 8's.

 

I'm thinking of runing a 1500W Inverter in the bed for charging my jackery and running other equiptment,
I have the stock TRD Off-Road Alternator, so I beleive I need:
- Big 7 Upgrade (1/0)
- DC Power Inc 270a Alternator
-

150a circuit breaker/isolator switch
- 1/0 positive and negative cables to bed
- 1/0, 3/8 marine grade tinned terminals
- 1/0, 5/16 marine grade tinned terminals
- Anderson SB175 hardware

(Cheap inverter which I'll later replace with a RedARC)

Does this seem complete?

 

Were you going to run your inverter from the starting battery? I'm just finishing a power supply with lithium batteries, 1000w inverter and a DC/DC battery charger.
