It is amazing.. But it could still be louder..

I have installed the Ultimate Lockpick which allows me to have an alternate input.. Such as DVD, MP3, etc.. I am using a player that plays multiple formats. I am splitting the output of this player into the stock Mark Levinson system as well into a Hifonics Olympus amplifier that separates the sub output signal down to any frequency I want.. 80 - 250 hz.. I run it at around 120Hz... this amp then drives two 10 inch Hifonic subs in an isobaric enclosure that can be removed when necessary.. When I want to bump..and show the system off, I use my alternate signal source which plays everything.. SAT, DVD, MP3, FM and TV broadcast..
