[QUOTE="deeciple, post: 8666530, member: 676351"] 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: [URL="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"]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[/URL] 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 [/QUOTE]
