Hi how can I connect my iPhone 6 to the jbl 20 speaker with out wifi?

SOURCE: HI ,

Impedance must be matched to have a better sound performance. Althought, it has no problem b/w 4 Ohm and 6 Ohm impedance-it still work but the system may get hotter due to impedance mismatching. You can try and see how the sound goes.

Testimonial: "Thats good advice."

I guess you didn't get the owner's manual, huh?

Where are the amplifiers in this scenario?

Page 8: The sub needs a subwoofer Line Level pre-out from an AV Receiver or multichannel processor. Though not elaborated on in the manual, the L and R Line Level RCA connections are probably for use if you lack a Sub Out feed. Running L and R from your receiver would allow the sub to derive a Sub Channel.

The rest of the speakers would connect to the AVR's speaker outputs.

Pasge 9: Alternate method if your eelctronics lacks a volume-controlled sub pre-out. This method routes only the front speaker level power to the sub so it can extract something resembling an LFE channel, then it routes speaker wire out to the front speakers, not as an audio power source but simply as a pathway.

You still need amplifier channels for all but the sub.

The only relevant speaker spec is the impedance. As you probably realize the Pioneer SX-255R recommends 8 - 16 ohm speakers.

Four ohms is on the hairy edge of too low. You could certainly try it but if any strain or excessive volume is used you could see something go poof!

The low end of 120Hz says don't push the bass to them.

Is it showing anything like " headset" maybe? Sometimes that's what the speaker is recognized as
