Honestly i'd do it yourself. its really very easy. all the connections are already in the trunk! i'm a noob installer and i figured it all out with the guides on this forum. you need an LOC, some speaker wire, i used heat shrink wire crimpers. a wire stripper, and a screwdriver. shops usually charge about $125 to install an amp, they shouldn't charge anything for the sub because you just have to plug it in, but some do. you'll save some serious cash.
