Is there any way to utilize the existing 4 speakers with the Sirius xm app on an i phone ?

Does the iPhone have a 3.5mm stereo jack? If so, all four speakers would have to be commonly wired to a 3.5mm stereo female receptacle and a male to male jumper would be needed, but I can't imagine how 'thin' it would sound since the impedance would be all wrong and the iPhone likely lacks the power to get the speakers excited enough to start dancing.
I reckon you'd need an amp with the requisite plug and wired to the speakers.

Thank you, Two Wheels. Two Wheels is definitely better.   I appreciate the reply. I have a radio guy I plan on visiting soon. I want to ask him if he knows a way to connect via Bluetooth.
