i like to fish
so i bought a used kenwood double din and hooked up my subs and was getting this whine and when i would rev my engine it would get louder accordingly. ( this sound was from the subs) . when i tried to play them they were playing really sloppy and didnt sound right at all. so I tried grounding the shields of the rcas and still the same problem ( the whine did get better though). so i switched to the rear pre outs and it worked perfectly but now I cant control the level from the headunit unless i wanna mess with the speaker settings. is there anything I can do?
