    Bass is the low end of the frequency range. So if you raise the LPF then you will be raising the frequency. Yes if it is all the way up an you drop it then yes it will increase the bass....

    No I didn't say that at all.

    I said that you need to leave the LPF as open as possible before adjusting the signal level to the sub. (IE THE VOLUME, OR GAIN CONTROL)

    Having adjusted the sub level so that the bass seems twice as apparent you then lower the LPF frequency cut-off until the bass level starts to appear marginally lower. By doing this you will find the natural extent of the LF response of your other speakers.

    Once this is identified then you readjust the SUB level (ie gain, be it positive or negative) to get what is an even distribution of bass levels between the car's own speakers and the sub.

    Can you find some specs for the active sub/power amp combination.

    What is the rolloff slope of the low pass filter. This should be quoted in dB/octave.

    TN69, you, too, are completely wrong.

    Bass is at the low end of the frequency range. Where as tweeters are at the high end of the frequency range? Explain?

    I may be wrong in explaining it. But how the hell can I be wrong about Frequency? Bass is at the low end treble is at the High end Fact....

    20-200Hz is thought of as the bass region
    200-2kHz is thought of as the midrange region
    2kHz-20kHz is thought of as the treble region

    This is what I was on about so how am I wrong?

    Just accept it and move on...
    HDi I tried. I tried putting the LPF off then adjust put the level up. Then adjust the LFP. And I had everything on the head unit back to default. It still has the bass drum really loud and the bassline isn't loud enough

    think this is where HDI is saying your wrong.
    the LPF only adjusts what frequencys are used by the amplier. it dosent increase the bass level itself.

    for instance mine allow me between 30Hz and 100Hz its set for 40Hz which gives me a nice punchy bass without all the extra vibrations due to the higher, 40-100Hz, being allowed through and amplified.

    I knew he was wrong... that's why I said he should move on.. but now this has happened. I'm sorry it had to come to this turbo.

    I think you're just taking it out on me because you were wrong. You know I've already got the bass/amp, I can't get another one now

    You seem to misunderstand me... I was trying to tell you about the frequency levels of bass. I may explain it wrong but I know what I'm on about. I'm not the 1 who can't set up a sub an amp am I? You have been explained how to do it plenty of times and still not done it. I think it is you who should accept that you yourself can't do and take it to a shop.

    You were wrong ok. Wrong, wrong and wrong my friend
    I may not be able to set up a sub and amp, but I can blast it loud... can you? I thought not...
    I have done as I was told to do.. and it hasn't made it the way I wanted. I did it the way he said though

    Yes mine is better than yours. Yours doesn't look nice at all. Very plain and puny looking...
    Anyway back on topic. What else could I do to fix this?

    Already got one. The sound on it is great. It's 90dB and it goes up another 18dB with bass. That's 108dB.
    The bass can go loud enough to make you bounce on the seats. I just want the mid bass to be vibrating more than the bass drum, that's all

    I honestly don't think your gonna get the sound you want from a Avtive sub? I had a single 12 in my car and that thumped. I only upgraded when I installed the tweeters and midrange in the front cause they drowned out the sub. But now the whole car shakes. The amp is running at 2 ohms which means it's pumping 2400 watts rms. This is why I say you should of had a separate sub and amp deal. How much did it cost?

    It cost £100 but that doesn't mean anything. I had good speakers to begin with, the bass was already thumping 10x louder than most cars' factory speakers would. I don't need any more bass or power, it has plenty. I just want the mid bass to be emphasised more than the bass drum. I'm sure you can do this just by modifying the sub settings as HDi was saying.
