Hello Richard, if your Bose Acoutimass 5 Series II, are compatible with your Yamaha RX-V379, using them in the L and R Front outputs of the Yamaha, this set is prepared to work between 10 to 200 watts of power, your Yamaha delivers 70 watts per channel, what is within the range of work of the Bose
I am sending you the link so you can download the Bose guide
I hope you enjoy the Yamaha-Bose convention

Yes. You will be able to run this setup with the sub bridged across both channels of the amp, which will give you more power (which the sub will be able to handle: 380 watts rms), or with the sub wired to a single channel, which will give you less power (125 watts rms). The sub can handle 400 watts rms.

Yes most PSU's are standard fittings. Certianly with HP. 160 watt is a very low spec look at 350 watt at least. Cheap enough to replace.

If you are asking if you can have a kenwood amp hooked up to your Sony Head unit then yes it would be compatable.

The 705 comes in multiple versions from basic that will give you heart rate to a team garmin version that has the cadence, speed, calories, etc. As for power meters the 705 is 3rd party compatible to show you watt measurements.
The following third-party ANT+Sport-enabled power meters are compatible with the Edge 705:

• iBike
• PowerTap
• Quark
• SRM

You need schematics and a good peak reading watt meter. You can do damage if you don't have eqipment/knowledge.

Any programmable UHF 450-470MHz mobile radio could be programmed to the frequencies of the Spirit MU series radios.

Your radios are 2 watts, so you would probably want to stay with a 1-10 watt, or 10-25 watt mobile radio, to have the best success. The current compatible model for Motorola is the CM200 UHF radio. If you are looking at a used radio, just simply watch for it to be UHF 450-470 MHz.

Then when you are ready to have the mobile radio programmed, the dealer (or programmer) will need to know the settings of your MU radios. These are easily read out over the phone, or in person by an experienced programmer.

You should be able to use the 25 watt bulb as long as they are compatible with the socket they mount in... Hope that helps...
