hi, I have these 2 new 12" subs that are a few years old. I figure I might as well get them installed.
what kind of amp do I need? will a mono amp or a 2 channel do the trick?
also, if I decide 2 upgrade me stock speakers, is there an amp that will run a couple set of speakers + these 2 Alpine subs? I also have a prefab BassWorx sub box, so it ain't gonna be a fancy set up.

anybody see anything here that will do the trick?
