I have a 2005 ford ranger regular cab which all of us know severely lack space to put subs. Last night me and my friend measured out a box that goes halfway up the window line and it came out to 3.85 cubes. so now were stuck on decidint weather to use 4'' aeroports or a slot port and which driver to use. ima definitely be doing a 2 10'' setup the ones ive got selected are the DD 3510, Fi Bl10, and the dc lvl4 xl 10. thanks for any input on this guys
