A:AnswerThey are hard wired and not wireless or Bluetooth. They sound great and I'm very happy with my purchase. BTY wireless speakers could drop signal sound and won't deliver the quality you are looking for. It really just depends on how big you project is.
A:AnswerI spray painted mine using Rustoleum exterior spray paint/primer. This was at least 8 years ago. Still look and sound great. I do touch them up from time to time.
A:AnswerYou should be able to. When you hook speakers in parallel, generally you halve the impedance. They are 8 ohm so left channel 8(1st), then hooked to another (2nd) would be 4 ohms, then hooked to one more (3rd) would be 2 ohms. Same for right channel.
A:AnswerYou can just cut the end off and strip the wire ends. Then unscrew the connectors on the speakers, insert the wires underneath the connector then tighten the connectors again.
A:AnswerIf you use a home theater receiver for amplification then you can use these. However, very few people do. Computers generally use plugs with connections that look like the headphone jack of a cellphone or mp3 player. (3.5 MM). These speakers need amplification and a pc does not provide it.
A good pc speaker is the Klipsch Promedia 2.1. Link below.

A:AnswerI don't know if they will install them up high on 2 story but I know they installed ours in our patio. It will prob have to be covered. Ours were about 7-8 feet up, they ran the cable from our house to patio. The cable is showing but that is the only thing the weather can get to but it is weather resistant.
