Happy Monday all. I am planning on adding a subwoofer/amp combo to my Ford Fusion. I don't want to replace the factory head unit, so I was planning on using an audiocontrol LC2i. Come to find out, the LC2i has an 18db/octave high pass filter set at 33hz. My first instinct was to return it and get the 7i version that does not have the filter -- but now I'm thinking otherwise. I have a vented box tuned to 30hz. The sub/box combo is modeled to have a bit of a spike - 6db or so - right around 33-35hz . Couple that with cabin gain [I do not know where this will 'start'] do you think it would be worthwhile to get the much more expensive LC7i? I am not planning on adding any additional amps.
Conversely, has anyone attempted to defeat the passive filter in the LC2i? Thanks!
