Tj, do you have a subs amp connected to your bimmertech amp's rca outputs? I'm thinking of getting the bimmertech amp also, I just found out after 2 years my Audio Controll lc2i has a built in subsonic filter that cuts all frequencies below 33Hz, all this time I thought it was the stock amp filtering out the low bass. My box plays down to 22hz when connected to my buddys head unit via 15 ft rca cables. It looks like my only option is to get the bimmertech amp and use the rca outs for my sub amp for a clean un molested signal. Do you have any bass cutoff below 33hz?
