I have a small amp that does 100 watts RMS @ 4 ohms. i know its not much, but what is the best 12" sub i could get that would only need 100 watts? (its for my moms car)
I would go with either the ID10V.2 D2 or a JL 12w0 depends if you want a 10 or a 12. You will be underpowering them both a little but they will work. Dont expect any serious output with that amount of power. They both will sound OK though for the amount of power that you are dealing with.
