Rocinante Posted July 12, 2016 Report Share Posted July 12, 2016 I installed a compact Kicker 11HS8 150 watt subwoofer with my new 8200 unit. The subwoofer is self-powered and connected to the h/u, and I also have a separate amp that is powering the four speakers. However, the subwoofer is very under-powered, even after I set the filters correctly. I have to lower the speakers to -24db and raise the subwoofer to 10db just to get it to marginal levels. Is there anything else to try, or is this subwoofer just too under-powered? Quote Link to post Share on other sites
david914 Posted July 12, 2016 Report Share Posted July 12, 2016 Make sure that you have the input level switch on the Kicker set to "Lo". Also make sure the gain control on the Kicker isn't all the way down. Quote Link to post Share on other sites
