I have a "new" (to me) 1988 Wrangler that has no stereo/sound system at all. I use it to go to the beach mostly, with some minor road travel. I don't want to spend a fortune on a sound system, just something to plug ipod into and blast music at beach. I'd like to be able to run it off the battery, but rechargeable is okay. I thought I'd try here first instead of going to audio shop. Thanks in advance for any help and comments.
