Im planning to replace my bose soon. Im going to go with an Apline 9815 headunit and MB Quart 6.5 components for the front. Im not sure about the rear speakers and the sub. I can get a used 12 Solo Baric L7 from someone for $130. A few others I have looked at where Infinity Perfect, Audiobahn Alum and JL (dont know which one). I want a single 12" because I dont want to take up a lot of room and im not going for loud...I want it nice and clear. Anyone have any suggestions?

 

Go with the solo. 1cf sealed. If you lived closer I would sell you a brand new one for $190. I bought four and have down graded to two.
Throw about 500watts at it and you have achieved your goals.

 

I'm selling one of my Elemntal Designs 12 O's. It is perfect for what you need. Really good quality sub and is not very space consuming at all. It is practically brand new, was only in my car for two weeks. Let me know if you're interested, I'm selling it for $160 plus shipping.
