Don't know if it will help or not, but here's Polk's info http://www.polkaudio.com/downloads/manuals/car/MM2008_Sub_WebMN.pdf

Not as aggressive as the one you have, but it did the job easily! http://www.signwareh...-HT-STPELM.html Don't know why, but the picture is straight on upload, but sideways here. Sorry.
