Remote Car Speaker's...?

[KLS123]

Hi,

I'm looking for a solution and would love some suggestions....I don't have an input for my car sterio to listen to podcasts/music on my iPhone 3G so I need some way to make it louder.

I do have an old iRock! without a power cable that taps into the FM radio.

Other options I'm interested in would be small portable speakers I could use in my home too, or a bluetooth that will play music and podcasts (does this exist? I haven't bought one yet!!!).

Okay...Please make some suggestions for me. I'm also a teacher and would like to play podcasts for my class.

Please help. Thanks!

I am thinking that any set of computer speakers would work by plugging them into the headphone jack of the iphone
