Help with underseat speaker and antenna

[jason999]

Hello,

My wife bought a Retro Sound radio and the kickpanel speakers that they sell with them, as a present a few months ago. My truck is getting close to completion so I finally got around to installing the radio last weekend.

So, I don't need a crazy sound system, but I thought that I could add a speaker or two under the seat. Can anyone help? Would a powered subwoofer work well for me? Are there and problems or special considerations, or does it just wire in and your set?

I know very little about audio. I am just guessing that a powered speaker would be best with this radio. If there are other good solutions, let me know.

Also, my truck has no exterior antenna. Can I just search hidden car antenna and buy or is there anything that I need to know?
