Need tuning help

both are just artificial bass boosts and the one at your amp is more centered around 45hz while the accubass tends to boost all around, i'd use that one over the amp bass boost and bass control on the LOC. Just use the main and accubass relatively high so your gains on your amp doesnt have to be too high.

Key things to remember,

- Set gains with your hardest hitting song, not a test tone, a 0 db test tone will leave you pigeonholed for output and you play music not test tones.

- if it stops getting louder or gets super loud all of the sudden and stops getting louder as you turn up the gains, You've already gone past clipping point, back it off.

- Play for a minute and check woofer coil and amp temperatures then keep checking every minute for the first 3 minutes then do a 10 minute run to see how hot either of your gear gets and lower gains if needed.

if you arent getting the output you want, consider tapping into a different speaker source or going to a head unit or grabbing a dayton dsp and bluetooth dongle.
