You must have an amplifier between the CD player and speakers. This CD player cannot directly drive speakers. Connect the audio outputs from the CD player to the CD input on any amplifier and then connect your speakers to the amplifier. You can use any speakers you like.

This player is actually a CD changer. This player connects to a stereo receiver and you have to purchase two speakers to listen to the CD's. Other components you could connect to the receiver are a turntable and/or a cassette player. This set-up would be referred to as a stereo system. Any brand of speakers would work well with this set-up. A CD player is one of those units that you can carry around and runs on batteries. This has two speakers built into the player.

I seem to remember doing an internet search when I was going to purchase it and viewing the schematics for hook up of the CD player's back board. It may have been an online Onkyo manual for that specific model. You would probably want to do the same for your Bose product. I certainly would think it has the capability to be compatible to your Bose, but you'll just want to review that information and be certain the proper connection wiring is available to you, prior to purchasing. You could always contact Onkyo customer support by phone and ask them your question (have brand and model number specifics ready before you call). This recommendation comes with the "I'm just a normal consumer disclaimer-LOL"! Good luck your decision.
