Second battery mod?

I have seen it on here, and I am tempted to give it a shot.
I got a 2013 DCSB v6 Taco and I am tempted to do the 2 battery mod.
Anyone know where that damn post went?

What I will be running:
4 Baja Champion 7inch offroad lights
1 Kicker DX1000.1 Subwoofer
2 6.5inch square LED Lights (the ones from the quantom light group buy)
Regular headlights and fogs

Any tips?

 

You don't need 2 batteries with those accessories but check out the ATO vendor section.

 

This one? http://www.tacomaworld.com/forum/2nd-gen-tacomas/252533-2013-dual-battery-install.html

 

Really? Would you recommend just running a Optima Red Top?

 

Exactly! Thank you

 

No problem!

 

so question... When is it needed to upgrade alternators? or is that not really a thing?

 

I'm no expert and someone please chime in if I'm wrong but the trd tacos have the 130amp alternator and I've not heard of the alternator needing to be upgraded for the sr5 or the trd.

 

So... Im only running a 700/5 channel amp and normal lights and such but If I roll up the windows while idling the engine will drop rpms and my interior lights will dim. Is this my alternator or what? is it normal?

 

Will check that. Thanks!
