Hey new here. So i own a skar 1500.1d. Have it hooked up to a sundown sa10, and works great. One "issue" ive ran into is when i turn the bass knob halfway up it gets loud (obviously). But anywhere past that it doesnt seem to get any louder or gain any volume. Im confused as to why it does that. I have tuned everything with the SMD-DD1 properly so im confused atm. I had a thought that it might be because i tuned it at 0db but im playing -7.5db music. But technically speaking there shouldn't be a "cutoff" point in volume. Any feedback would be helpful.
