have a 9515g and a opti2000d and with my 490ib I am just not getting loud at all. Is it safe to raise the sla to +4? Or the bass settings to +4? I want the real boomy bass and I just can't get it! My gain was set with dmm. Any tips with this headunit?
sorry I did this on a phone so my grammar is probly horrible.
