Before you guys flame on me and suggest I go ported, please understand that space is going to be an issue for my trunk. It is going to be a Lexus GS Sedan. I am going for sound quality, but would like to get loud as well. The amp that I will be using will be a single Rockford T25001BDCP.
Should I get 2 15" Fi Q, each in their own individually sealed 1.75-2cft box, or
a single 15" SP4(not sure how good they sound) in a sealed 3-3.5cft box?
OR even 2 12" Fi Q each in a 1.5-2cft sealed?
I know these volumes for the 15" Fi Q are below recommended, but I have no choice.
Any tips would be great.
