HI, I was happy with my sub response when I had added some bass boost on the crossover but I've done a lot of reading and research these last months and everyone states that it's not recommended or needed. After that, I've done my gains properly several times, following all the recommendations I have seen online on different websites, but I can't feel my Fi Audio SP4 15'' sub D2 (in a flare ported 3.5 cu ft box)as loud. My JVC hu settings and my Crescendo 3500bc are correct and I've done the tuning/setting gains with the 40hz tone at 0db and I found the bass response very low, then I did it at -5db and I still find it low. I know most of you out there listen to American music(hip hop, r&b, etc.) that have lots of bass, but I mostly listen to Hispanic/Caribbean music. I'm guessing I'm using the wrong frequency to tune my bass due to the fact of the type of music I listen to...
1- What frequency you recommend for me to set my subwoofer/bass gains with?
2- At what db , for the loudest/cleanest response?
3-Also, What's the best frequency and db to tune/gains the Image Dynamics 6.5 mids on the doors?
