I recently upgraded the stereo in my 2012 supercrew. I decided on Diamond Audio again for this build where I have used their stuff on 2 previous vehicles. FJ cruiser and Subaru. Both sounded excellent. For the raptor I chose. Diamond Audio H65s speakers for front and rear 2 12” shallow mount diamond subs HX1200.5 amp Audio control lc7 Still the music is lacking a full sound to me. sounds like it’s missing certain frequencies. Any suggestions? Do I need another dsp or add in an equalizer. Or is there a way to bypass the factory amp that may be the culprit.
