subwoofers use mono amps not 4 channel amps.

so something like that would be best?

Look into Kenwood head units. They are a lot better than jensen.

kenwood subs no

Best bang for your buck right here thats my setup and it slams

As for your head unit thats up to you but i suggest just getting a kenwood one and not a gay flip up one lol

Yeah i like it. But im not sure if its compatible with my car

Subs and amps are universal.

Oh okay. So its the head unit that i need to be more careful about? Im assuming sprakers are universal also?

Nope they are universal as well. All you really need to pay attention to is door speaker size, and then the wire harness/mounting kit is specific to your vehicle too.
