hey guys this is a great and informative site!. I have a 2003 mercury Grand marquis stock everything when it comes to electrical, system wise i have 2 15" kicker cvr's in a sealed box powered by a 1400.1d autotek amp, and truth be told i want to upgrade my subs. I was looking at the FI selection but cant figure out wich one best suits me i mostly listen to hip-hop and was wondering wich Fi sub would be louder then the cvr's i was thinking maybe a 1 15" in a ported box or maybe 1 12"? Thanks for your help n time oh BTW i have about $350 to spend thanks

If that $350 is just for the subs then you can look at one 12" or 15" BL or you can get one 15" SSD or possible two 12" SSD's (if you increase your budget slightly). Its all up to you, but these subs will cost more money for a box and the electrical to back that up (so hopefully you have some more duckies for that also).

yea i figured i would ghave to sooner or later upgrade my electrical but for the first step i wanted to buy the subs. so as far as upgrading u think 1 15" Fi ssd ported would be much louder then the 2 15" cvrs?

louder is really install dependent, but u will move more air with 2 15's as compared to 1 15. i would try building a new box for the cvr's first, then if ur not satisfied try upgrading, bc i have heard cvr 15s gett pretty darn loud.

Yeah as stated above louder is install dependent, but usually 2-15"s sealed are equal (give or take some) in ouput to 1-15" ported. I would either build a ported box for those 15''s first since it is cheaper, but if that still does not do it for you then upgrade. Just my .02

ok that sounds like a good idea, would you guys know where i could find some plans on building my own box specifically for 2 15" cvrs ported? Again thanks alot for your help and time i appreciate it

Yeah there are a couple off box builders here this forum who will charge your for designs or you can post your max dimensions and Im pretty sure someone will help you out.
