SMD DD-1 | how I set my car amplifier gains | Rockford Fosgate

[@lucidthoughts4519]

Question. Here’s my scenario. 8 channel amp with a combination of 6.5s, 6x9s and 8 inch speakers all mids and highs hooked up. Once I know my max vol at the head unit before distortion, then I set the gains for each channel using the dd1 until the red light comes on? It doesn’t matter what size of speaker is connected to the channels or if there’s a pair bridged? I’m just to simply go based off the red light going on and back off the gain until red light goes off?
