Summary: Bose has thought of almost everything. I love the way you can use this amp as an extension to another room from your home theater system. They make it so easier to get music in any room of your house.
Summary: Great Purchase. Great Seller!! Great piece to add to your bose entertainment system. I went ahead and bought this piece to have sound in the patio and inside the house. YOu can add two recievers to this amp. IT will help in the end for you to prevent your from over powering your speakers..
Excerpt: The Bose expansion amplifier SA-2 is a great option for those wanting to expand additional speakers to another room. I used it to expand speakers on my patio. The only drawback is that these amplifiers are strictly audio only, so the expansion remote control may say TV and DVD, but you will only be able to hear television shows and DVD movies from the expanded room not able to add video components to sync with SA-2 audio.
Summary: What can you say its a Bose. If the product was an issue, Bose would back it up. The SA-2 amplifier is a great all around unit that is used with a majority of all Bose Lifestyle Systems. I am running 3 SA-2 and 1 SA-3 in my system and have not had any troubles with any of the units. Again what can you say, its a Bose.
