extra battery and smd dd1

[scionicboom]

So the dd1, has been used on my amp to set the gains now currently I have one battery under the hood I plan on putting a new battery in soon so would I have to retune my amp with the dd1?

[ROLEXrifleman]

no

and I'll edit myself to say no if there is not a substatial increase in voltage.

Only reason you would need to retune your amp is if you changed head units.

Ahh thank you very much!

You should not have to unless you gain alot of voltage...possible but unlikely for example if your amp is doing idk lets say 1,250watts rms but you are at idk 12.5 volts now and you add another batt and go to idk 14ivolts then your amp will put out more power mayb 1500rms??? i made all of those numbers up...you get the idea...so short answer prob not but check your voltage before and after....if it goes up alot then jus recheck to be safe but you should be ok.
