Will a Bose SA-3 Amplifier work well with Bose 151 SE Speakers? Based on the information of the Bose 151 SE cut sheets, they are compatible with amplifiers 4-8 ohms and 10-100 watts per channel. The Bose SA-3 produces a 100W per channel minimum into 6 Ohms. While they appear to be compatible based on the specs, I just wat to confirm that I will not blow the speakers. Thanks in advance for your help.

To connect an SA-2 amplifier to a BOSE 321 Series II Media Center, you will need to use a 3.5 mm audio cable. Connect one end of the cable to the headphone jack on the SA-2 amplifier and the other end to the auxiliary port on the BOSE 321 Series II Media Center. Once connected, you will be able to enjoy amplified sound from your media center.

Could be the impedence of the speakers that you're connecting. The bose amp was designed to drive 8 ohm speakers.

You may have overloaded the amplifier if the speakers are not 6 Ohms or higher.

No!

This is what it says in the manual:

The Lifestyle

stereo amplifier is designed for use with Bose non-powered environmental speakers or
Bose non-powered accessory speakers ONLY

If you want to run both the speakers at a time you will have to buy a professional amplifier like CROWN XLS202.
Because together the total impedance will drop below 3 Ohms. An average domestic amplifier is designed to run speakers between 4 to 8 Ohms.
If you are running only one pair at a time you can buy any of the following Amplifiers.
Marantz - PM 7003
NAD C356

Make sure you unplug your sa 2 and sa3 amplifiers after setting the codes. Wait at least 60 seconds, then plug back in. I would also unplug the in and out boselink cables as well. Once youve waited for a minute, then plug everything back in. Should work. If not, call Bose technical support. They are really great. I have 15 SA 3 amplifiers throughout my home. They are great.

How many ohms is your sub? The SA 3 Amp can only handle speaker(s) 6 ohms and greater. A lot of subs, as I understand, are 2 and 4 ohms typically. If yours is 2 or 4 ohms, then that explains it. The speaker would be "straining" your amplifier and blowing it.

Take a look at Marantz's ZS5300 6 ch amplifier. that'll give you 3 stereo zones. Good luck!

Hi

I checked in the specs of the manual here. page 6. They quote it as being suitable for 4-8 ohm AMPLIFIERS. but do not mention the actual impedance. I would expect from that that the speakers must be close to 8 ohms, as you they would not advise you to connect a 4 ohm speaker to an 8 ohm output stage, as likely damage could result. If you had a multi meter, you could do a DC resistance check of the speaker, this is generally very close to the impedance. happy to talk to you more about it.
