Hey right now I have a pioneer head powering 3.5Kappas and 6x9 Dragsters with a Rockford Fosgate 90watt rms powering a MB Quart 12". I listen to mostly punk and hardcore, stuff like that, so this is all I really need. So of course as anyone with a system knows, theres always room to go louder. I was thinking Alpine V12 for the interior speakers, but thats where I get lost. What kind of amp would be good for the sub? And, if improving the interior, should I keep the 12? I heard 10s are punchier, and Im not looking for deep bass, it should hit hard? Any recomendations would be great, also, how many watts should the sub be pushing, if each interior speaker is hitting 40 watts each?
