Ithertz84 Posted April 3, 2021 Report Share Posted April 3, 2021 I have a 4runner and 18" AQ hdc3 sub,(have 2 but airspace better for one) and a 3500.1 AQ amp (audioque)<for now I have stock alt,d3400 xspower battery with big 3,will that be enough or I need a secondary battery like a d1200 in rear?? YES, I will be buying a 320 amp alt(for 100$ more I can buy 350 amp alt) but for now ill be running a stock alt when I install it.. waiting on my box quote cause no one local to me(KY) can build a box then hour away, so waiting on a call to get the quote before they start and then, I have to wait 2 weeks until its done!! so now I'm buying everything I need until its done Link to comment Share on other sites More sharing options...
Dafaseles Posted April 3, 2021 Report Share Posted April 3, 2021 The 320 should do the trick, and 2 batteries should be plenty. Just the one D3400 might be pushing it. But if you can swing the extra $100 and get another D3400 for the back instead of a D1200, that would suit you better in my opinion. 2011 Chevy Silverado under construction My build log here.
