Alright so Im in the jist of buying a sub(s) for my ride a Crown Victoria.

Im not sure what I should get, Heres what Im considering.

And a Hifonics HFi1000D, wiring the set up too 1 ohm.

or 2 Alpine SWR-1243D 12's for 300 wiring them up too 1 ohm load as well on the same amp.

I would prefer a nice hitting system where i can feel powerful bass, but it can still be accurate.

Im not sure what to get, either way Im putting them in a ported box.

Any other suggestions welcome (dont be afraid of suggesting large subs,boxx size is not a problem for me!), but keep in mind I have a 300 dollar budget for sub(s)

Thanks for the help in advance.
