[QUOTE="Omega3dog, post: 5245599, member: 580111"] Beneath the rear seat after installing the other equipment. [IMG]http://i498.photobucket.com/albums/rr341/Omega3dog/Car%20Audio/DSCN0633.jpg[/IMG] Keep in mind, I did my own calculations and built the enclosures myself. My only disappointment is this...the vent calculator on the carstereo/help website [URL="http://www.carstereo.com/help/Articles.cfm?id=31"]http://www.carstereo.com/help/Articles.cfm?id=31[/URL] is not so accurate when calculating vent length. For example, tuning a 1.5^3 enclosure to 35HZ using a vertical slot vent 4"w x 9"h, the calculated length is ~46". If the same vent is turned horizontal, the calculated length is 43"; resulting in a 3" varience for identical port areas. If someone logically understands why, please share. The following two pics focus on the Fi 12Q enclosure... I'm so glad I paid attention during my high school geometry, algebra and wood shop classes.
