That is about where I set mine. Do you have a good midbass setup?

no mostly highs coming out my speakers

low pass crossover for your subs should be 80 imo

whats imo?

imo = in my opinion

so turning it up would give me more mid bass and down would be deeper

are you saying that your subs are playing highs and not lows

the low pass crossover set at 80 hertz will allow your sub to reproduce frequencies 80 hertz and less and will reduce output on frequencies 81 hertz and higher

I like to set mine at about 80 too... most subs don't play really well above about 100hz anyway so setting it higher than that really doesn't benifet much of anything

why don't you tell us what all the settings on your sub amp are set at 1st

and also what settings on your head unit are set at 2nd

then we may be able to help you better

the low pass crossover set at 80 hertz will allow your sub to reproduce frequencies 80 hertz and less and will filter out frequencies 81 hertz and higher

I could be wrong, but I believe its sloped...So 81 would not actually cut off, thats where the slope would begin
