Yes, get into the speaker and solder the wire directly to the crossover. Every audiophile knows this is the only way to get REALLY good sound.
Or, you could just match + to + and - to - on top or bottom (or even one each if you want) and listen happily. If you are missing the jumpers that connect top to bottom you can make a new set with some extra wire. Just make sure that jumpers only go from like polarities or you may cause a short.
Next week, after you have tried it the normal way, you can email Mitch2 to get the details of how to hardwire your CD player directly to the tempanic membrane of your inner ear.
Good luck!
