Im currently running an icon 12 in a 2 cu ft ported enclosure tuned to 32 hz on a sundown sae 1200 v2 @ 1 ohm. I had a pair of fi ssds (d1s) before this, but i only ran one. when i bought the icon, i sold my friend one of the ssds and planned to throw the other in my gfs car but i never got around to it. well my friend has had the ssd for almost 2 maybe 3 months ago (has not used it) and text me the other day and asked if i knew anyone that would want to buy it ($100...i sold it to him for 125). so im kind of thinking about buying it back. the amp i have for my gfs car is a rd 1000 v1 amp (ik not the most favorable company, but ive had the amp for 5ish years and not a problem). if i do buy the ssd back, i was thinking id run them sealed in my car and throw the icon with said box in her car. sealed because 1.) i want to keep space in my trunk 2.) i think sealed may be bettter for my listening habits, i listen to a lot of rock and alternative and some rap. she on the other hand only listens to rap. but the part making my decision tough is ive never ran sealed. i understand its all install depend, but would i be losing output switchin to two 12s sealed? i mean its twice the cone area but itll be sealed. i do want it to be louder obviously. and will a sealed box still hit the lows like my ported set-up? if its a favorable situation, ill have more questions on building the correct size box for them. ik shed be happy either way but i dont wanna downgrade to make it that happen lol, selfish i know. btw my car is a buick lesabre, yes it has a massive trunk but i take alot of trips to chicago and i use wat trunk space i have. if its not favorable for me to do so, shell just be gettin a single ssd @ 2 ohms off the rd. im satisfied with my system as is but louder wouldnt bother me
