I have a Fi Q 12 in my 01 accord. it is being powered by a sundown 1000d. im running 4 gauge wire and knu rcas. the headunit is an alpine 9855 and when connected there is barely any bass. The bass is set on +15 on the h/u but there is still barely no output. before it was in a pathfinder on a p7600mp and there was alot more output. Maybe its the headunit? or something wired wrong?
