I have a sub/amp installed and need to upgrade my speakers b/c they dont seem to keep up. I dont want to spend to much $$$ b/c I try to save it for speed/looks mods.

PS: Also the rear right speakers seems to be rattling (like a torn paper rattle) when the base hits.

 

Probably the best bang for the Buck Speaker out is the CDT base line (CS) speakers. Next up is probably the Infinity Kappa and MB Quart Reference.

 

A lot of people on this board and nasioc (subaru guys) have really liked image dynamics and elemental design speakers. The comps. are around $300.

 

I got polk momo component set all around, and there 180 a pair. not bad.
