there really isn't anything to hooking it up...just gotta run the wires...not hard at all... for your budget i would into maybe a w7 or l7...or earlier models possibly with a profile amp....my current set-up for about $150 is a power acoustik LT980/2 and an RFP3812...poor sub but it still sounds good...i'm waiting for my audiobahn to come in...i had two twelves and they fit in the trunk nicely sealed...can't go ported with them really with the limited space involved...can port 2 10's possibly but i don't understand what u are doing with ur "false bottom". for $600 you can get an awesome set-up that can be heard and felt from far away...good luck with it...i screwed myself with my first set up and am hurting now...another helpful choice is
www.sounddomain.com thats where i learned everything...many ppl shall bring on other set ups for you...pick the one that suits you best---peace
