Pioneer eq settings

[bassaholic]

ok i have a pioneer 4600 it has 3 adjustments for eq low/mid/high if i boost the mids and the highs at lets say +2 every thing sounds good but the bass if i boost the lows it sounds crappy so i leave it flat.If i drop the mids and highs flat or under my bass sounds awesome again but the highs doesnt sound half as good i mess with the parametric eq and all that same thing happens is this normal? I probly gotta make a change to a better sounding deck

Well after a hour or 2 of mess with the deck i finally get the bass how i want it had to set lows at 3+ then drop the lpf on the amp lower sounds smooth and more accurate now i guess this deck ***** at bass output never had to boost the lows by so much b4 on any deck i had any comments?

it sounds like you have your eq flat since u set everything to 0 and ur bass might sound awesome too since you own the great epicenter. Im planning to get something like that but its gonna be the soundstream digital bass machine functions similar to the epicenter.What model pioneer deck you have inches?
