Hi, guys

I just bought two Polk Audio DXi124 DVC 12" with two 12" dual ported box from bestbuy.

Polk Audio - 12" Dual-Voice-Coil 4-Ohm Subwoofer - Black
Fierce Audio - XED 12" Dual Ported Subwoofer Enclosure
from bestbuy

here is the question,
my car is a tiny civic, do i really need to use two 12" sub?

Option 1:
Sell the extra Sub and the two boxes,
then use the money to buy an amp.

Option 2:
Sell one box, then buy a a decent amp to run the two sub.

any suggestion?
