i use to set my gains using 0db test tones. last week squeak and some others suggested i use -6db test tones to set my gains. boy am i glad i listened to them. my system is so much louder now.. and i dont even need to turn it up as much as i use to and i **** sure wouldnt want to simply becuz its TOO loud. ive got infinity perfects and a 12" idMAX. im surprised u guys are having this problem while my system is nice and clear.. but i AM lacking a certain midbass frequency range that i cant seem to fix. anyway, i think if u guys got yourself a dandy little EQ, maybe one with like 13 bands, u can eq the "tweeter ranges" some and some higher midbass to bring out vocals like ive done.. it takes time but the littlest changes make a big effect on the overall sound and i love it! oh yea, i would maybe turn my sub's gain down a little cuz im pretty sure most people crank their sub amps up higher than they should because they love the bass, yet dont know how much theyre drowning out their comps (assuming their speakers are crossed over where the sub leaves off)
