Plse help....I have set up a new system in my 2004 cavaleir, but cant make the subs sound right in the trunk,I am running 2x 12 in subs in a ported box,they were fine in my mini-van ...but i'm not impressed with the trunk,I also overload my amp(it goes to protection mode) when i push it(it never did this in the van)..also it sounds WAY better once I open the trunk
