I am fixing to begin my audio overhaul and have a few questions to those who have done it before. I own a 2004 cc. I am wondering as to what sub size will fit under the seat based upon air space. Most CC and Ext. Cabs truck require shallow mount subs. Is this true with the Titan? I am thinking about 10s as I like the clean bass but would consider other options. Lastly, I have looked for days and can not find many 'real' reviews on subs and mids from professional installers.. most are people who base their claim on what they bought and don't want to feel taken. Any suggestions as to mids for the doors?
