Welcome to NICO!
Pictures when you get a chance, please!
Speaking without true knowledge (so be warned!), I would expect that these jacks (if they are analog audio input jacks) should allow for any line-level audio (i.e., less than 1 Volt peak-to-peak - or so - at "full" volume) to be fed in.
So, if you use the "headphone" jack output from a player, you should be careful, in case the player output exceeds that value. Since most headphone jacks from players are pretty low voltage outputs (I think,) you should be okay. But start with the volume set low and experiment.
Just do make sure that these jacks are indeed analog audio input and not some digital inputs (or analog outputs)!
I would strongly recommend downloading the full service manual from the Infiniti technical info web site (costs $20 for a full day access to the site - cheap for the money and do get the TSB's while you are at it) ... I forget the exact URL, but you can do a search here for "techinfo" and it should show up!
