lol when i 1st got my hu i set sub volume at +10 too.. any boost or in that case it's more like boosting gain to sub i'd think which will make u clip.. u can set gain with 50hz tone set amp for 1500rms @1 ohm that would be 38.7v on meter., turn all bass boost off, eq's flat, sub volume at 0 is ideal (but since u wanta use it maybe leave it at +5) put hu volume at 35-40 turn gain on amp up or down til meter reads 38.7 or close (unhook speaker wires and just stick meter probes into speaker outputs on amp) once u do this never go above what ever hu volume u set it at and don't boost anything any higher (unless u play rock music or something with very little bass)

I guess theres different ways of setting up. I read a lot of people max sub level @HU
