    Subsonic filter on speaker leads?

    Sounds like you have a phase cancellation issue. Make sure the polarity on your leads correct. If the polarity on one of the leads is reversed the sound from one channel will cancel out the other when they are combined. That's why it sounds stronger when only listening to one channel or the other but weaker when listening to both. Check the "Phase cancellation" section in this FAQ to see what I mean: https://www.bazooka.com/faqs Hope this helps. Dee

    Subsonic filter on speaker leads?

    Ya, not much I can do about a preset crossover point. The stock speakers provide surprisingly good bass though; very clear, punchy and deeper than I had expected. The sub picks up right around where the stock speakers drop off. Turns out the BTA-8100 also has a built in subsonic filter that starts to roll off at 35 Hz. Doesn't seem to be doing such a good job though

    Subsonic filter on speaker leads?

    Thanks for your reply and the link. You mean the built in line level converter on the Bazooka?
  4. Hi Folks, I have a 2017 Nissan Altima with the stock sound system (not the Bose 9 speaker). I am happy with the sound except that it is missing something in the bottom end so I added Bazooka BTA8100, 100 watt, 8" active bass tube. This gives me what I want except that I notice that there is a lot of very low rumble (even when no music is playing) and the very low notes seem more pronounced than the upper bass notes. I have done a bit of EQ'ing to smooth out the bass notes but I think I need a subsonic filter to eliminate the rumble. I found these FMOD units that I think will do the trick: https://www.amazon.com/FMOD-Crossover-Pair-High-Pass/dp/B0006N41CO/ref=sr_1_2?ie=UTF8&qid=1548282591&sr=8-2&keywords=fmod+high+pass Although I am tapping the rear speaker leads to the high level inputs on the Bazooka and they are line level only. Is there a speaker level equivalent? I suppose if not I could go with a LOC and use the RCA inputs on the sub. Would this combination eliminate the rumble I am getting? Also, these come in different frequencies. What would the best frequency be, given the characteristics of the bass tube I am using? Thanks in advance for any help. Kind regards, Ken
