Question by Robert: What kind of car audio amplifier(s) do i need for 2 subs and 4 speakers?
I'm looking to get a brand new audio setup in my car. I don't think my head unit (JVC KW-NT30HD) will be powerful enough to power my speakers. So i think i will need to get 2 amps unless there is one out there that can handle 4 speakers and 2 subwoofers.

The 2 subs Ill be using:

Rocksford FosgateT0D410 :

10" subwoofer with with selectable 2- or 8-ohm impedance
Kevlar® reinforced paper
