computer desk built in speakers

I have an IBM M Pro and the speaker built into the front at the bottom. I want to add speakers up service?

I have a stain on the back for my computer to connect and I did and the table of the best speakers work, but the built in does not disconnect equipment unless others. Is there any way to have all started. The speakers are Infinity table, nothing big and fancy thus no way to have more sound, so most speakers go.

It is designed well for use with headphones when you do not want the sound coming from the speakers. So when you connect headphones or external speakers is cut internal.
