    Amp tuning, correct HPF and LPF levels?

    hi,

    was playing around with my amp settings and wondered if anyone knows the best settings for the HPF and the LPF to use to get a punchy sound from the sub?

    ive done the best i can and its ok but there must be an expert on AOC who knows the best settings for these?

    also theres a adjustable gain setting as well dont know what this does?

    cheers

    What setup/speakers do you have?

    LPF is low pass filter for the sub, HPF is high pass filter, sometimes used for the front speakers, but you could leave these on 'flat' to get all sound frequencies from the front.

    Gain is how much the amp increases the input volume - generally, turn the HU to ~75% output volume with the gain at minimum. Gradually turn the gain up until the sub distorts, then back it off a little.

    LPF - for the sub I tend to have mine around 80-100Hz to keep the sub doing the bass only.

    thanks nry,

    i have standard speakers (they sound good to me)

    and with the sub i have a jl audio 1200w i am told and its in an enclosure with a plastic cover, this is connected to a mutant amp (no idea if any good)

    it sounds fine considering it was £30!

    oh and i have a pioneer head unit (silver one good spec though but cant memba model number!)

    erm will try those specs you suggested

    but i want like a very punchy bass not always low and loud

    guessing your setup is good for this?

    i agree, keep the sub for bass, but all depends on what sub and amp u have, id reccomend just keep playing around with the settings till u find the one bewst suited for you, that way you learn a bit for future referece, dont go too high on the sub as can cause damage, check the sub spec with amp spec too,

    The above is a good starting point, then tweak to suit
