Very nice on the install. I have a 12" Memphis Audio subwoofer in a ported truck box in my rig along with the Pioneer DEH-P4800MP head unit and a 250 Watt Phoenix Gold Amplifier. I love it, me being 17, of course I want that huge bass and this one sub sets off car alarms and rattles windows. Thank god for ported boxes and friends that are car audio experts.
