Tuning Amp
After a lot of research, I’ve finally tuned my amp! I used an oscilloscope from my work and tuned my gain playing a 50Hz test tone. I made sure the bass know was all the way up, I had no EQ on my head unit, and the volume was at 75% of its max. I got my signal right under clipping, just like all the advice online says. My only issue is the sub feel underwhelming unless the volume is at 75% of its max. I’ve definitely had the gain set higher than what the oscilloscope had me set it to. The lower frequencies (30-40Hz) feel so quiet now. Any advice here? Should I turn down the head unit and tune it from there? My oscilloscope only goes down to 45Hz so tuning below won’t be possible. I’ve also tried tuning with a multimeter and it had me land right at the same spot. I feel like it’s important to add that I’m using my stock head unit with a rather cheap line output so I’m thinking that’s where my issue probably lies. For my sub being able to handle what it can, it just feels underwhelming unless at 75% power. System specs below
