hooking up something like that has been HEAVILY discussed in here.
12 volt conversion, yada yada, car amp.
i dont see why people keep doing them myself.
If your building a jukebox its assumed you have woodworking skills (not trying to snooty or snide here, just making a statement).
Parts express has sales all the time on speaker components. You can turn the bottom of your jukebox into an enclosure and mount a pair of 12"s down there. They have some decent sealed back midrange drivers you could mount anywhere on your cabinet and not worry about enclosing, add a pair of super tweeters up high at head level and you'll have all the sound you could want without having to build arround existing boxes.
If you want booming bass use Professional Audio PA woofers. Their catalog lists how much volume is recommended for sealed and ported enclosures for the various woofers. Watch yard sales for integrated amps, the home stereo variety. You should be able to pick a good one up for $20. Mine is a Pioneer sx-203. It will produce way more volume than needed at 100watts per channel plus it has the Sbass button to enhance bass at lower volumes to keep the "boom boom".
