How do you wire these?

I soldered mine to my Altec Lansing BT Speaker. Speakers have + - to wire to.

How does music sound? Can I build a boombox with two of these speakers?

These speakers are tweeters only for high frequencies. They sound great but you’ll need a mid range speaker and woofer for overall performance.

How can I make a speaker with these and what would I need?

These little speakers are best suited as replacements for the elements in high-quality earphones. To use as an independent speaker, you would need to mount them in an enclosure. Be aware of the power limitation of 3 watts.

Are these “waterproof”? i need to replace one of the speakers in my ijoy speaker. they look the same as what i have, plastic cone, etc.

These speakers are definitely NOT waterproof.
