For anyone having the problem where the subs play a loud note like when the trunk is clsoed and HU is turned off, make sure you have the stock sub UNPLUGGED when u have aftermarkets installed. For some reason the stock sub and ur aftermarkets will battle each other, in a sense, if stock is still plugged in, kind of a complicated problem, even the car audio guys couldnt explain. If your still having the problem i recommend just getting a little amp turnoff switch that ties into the acc wire, cheap like 10 bucks at any car audio place. Hope this helps.
