Jeremy009 Posted January 7, 2022 Report Share Posted January 7, 2022 Hello all, A question about headunit signal and setting gain. The headunit is an 80prs and a rockford r2 500.4 with the clean in clean out feature. So when finding the max volume on the headunit, you use a 0db tone at 40hz and 1000hz respectively. However, if you want to use a -5db tone when setting gains for your mids and highs, wouldn't that change the distortion level you just found on the headunit at 0db? Or are you to use -5db to check both headunit signal and gains Link to comment Share on other sites More sharing options...
Dafaseles Posted January 7, 2022 Report Share Posted January 7, 2022 It will change the value. What I do is find the max has unit at 0 db, then set the amp gain with the overlap. Here's some information about why and how we use an overlap that I found good information 2011 Chevy Silverado under construction My build log here. Check it out!
