Dual battery

[Brooklyn hoe]

As the title states does anyone know of a good audio shop that can install a dual battery set up on my 2007 tahoe. I leave in brooklyn NY but willing to travel to get a professional clean job done. thanks

It's not that big a deal. If you have the room for the second battery tray and the factory mount area is there then just get the tray and install it, add the battery, attach a positive cable from the first to the positive of the second battery, add a separate ground cable and attach at the block. You are done. If both batteries have the top and side posts then it is a cinch.

Wouldnt an alternator upgrade also be needed? And a Big 3?

No. All you are doing is just creating more cranking amperage that is especially helpful in cold weather. If you want the dual battery for a bunch of radio and audio mods then you should do a bigger amp alternator. The guys just said they wanted dual batteries but not why.
