i mean before when i ran a hdc3 18 i got pretty good numbers out of what i had. my best average 145.xxdb. the org i compete in is a 3 round music average(kick, dash,headreast) my bests were kick-147.6db, dash-146.4db, seat-145.5db. these are just my best scores at diff mic placements. which to me wasnt bad considering my electrical was stock, i had 4 gauge wire and no big 3, with 1 18 hdc3 and planet audio bb2400.1 thats was refurbed and probly doing like 600 rms lol. so i was pretty happy with that lol.
