nice... I bet it really does sound amazing and loud. Now... here's what we'll do... let's take off those polk db both front and rear and let's hook it up on a 2007Honda Stock Head Unit... tell me if you'd still be happy with the db's SQ and effeciancy...??? BUT, if think I'm wrong or anyone want to prove me wrong... then by all means... do so... maybe the rules in "caraudio system building" have changed.
