Anyone ever try making a diy filter for there subs/speakers.
Im trying to make a filter that with a cutoff of around 100hz for my sub. But everything I hook it up it doesnt work. Im trying to use the basic RC design with the cap at 2.2 uF and the resistor at 1k.
I have had this circuit working on other applications but for some odd reason I cant get it to work in this scenerio. Is there some thing special about car amps that need minor tweeking. I think the main problem is that the - is not just a ground. Another thing is I think that I had it working for a couple minutes but now nothing.
I know I could probubly go to the store and pick up a passive xo. But I have all the parts right here, to come up with any frequency cutoff I want with any slope, and this is really pissin me off.
