Want to replace stock battery 05 Escalade EXT for new 2x RF t1412's & 1 RF1500bd

What battery would you guys recommend to replace stock starting battery under the hood? 05 Escalade EXT 6.0

Also, do I need to replace anything else (wiring, alt ect.) when upgrading to a high performance battery?

Thanks newb here

Xs d3400 and a set of xs 551 side post adapters

Doing the big 3 on that vehicle is a bit fucky but can be done

Hi if you are just replacing the factory battery with no upgrade to sound system then yes the D3400 with side post adapters is what you would need! thanks!

Chris, I just recently had 2 t1412 RF's put in a ported midgate box along with a t1500bd amp, everything else is stock. If I replace my stock battery with an XS3400 do I need to upgrade the wiring to the battery as I have not done the big 3 upgrade yet?

Thanks for all the replies so far guys.

The big 3 in your vehicle is a little differant. You have to put your ground through thr battery current sensor

Thanks ToNasty,

Until I do the Big 3 can I still install the XS battery without any modification?

Just a 551 side post adapter

Also, which alternator would you recommend for my vehicle since its a bit different in that regard?
