Already purchased one set, since you can't change the naming convention are there work arounds or do you buy a different brand for within the same hou

I assume you are referring to the bluetooth name. I have 6 units, they all use the same name, but that isn't a problem, because they don't advertise unless you push the volume knob. After you pair each one, rename it on your phone, no need to rename on the receiver, the phone can tell them apart. So if you have previously paired to a phone, when you turn the unit on it will try to reconnect to its existing paired device. If you want to pair to a new device, press the volume knob while you are scanning for devices from your phone, then rename it in bluetooth settings on your phone after it is paired. The only time you are going to have an issue is if you press the volume knob on 2 devices at the same time, you wont know which is which, but since you probably cant be in 2 rooms at once to do that, shouldn't ever be an issue, and whichever one it pairs to, you can rename to distinguish which is which..

I don't want to plug this in and instead wish to hard wire this unit. Can someone provide a link to a 120V converter that I can use?

Hi sounds like you dont want to see the tranformer , with cable running down the wall. What I did with mine if you know about wiring electrical and things like that I cut the wire from my Transformer to the unit and I made it longer and I run a wire up into my attic where I have a light switch with a plug .plugged in the transformer ,made the wire longer so now it's a hard wire unit basically that's what it looks like because all you see is just the unit in the wall with the faceplate no wire sticking out of it and that's how I did mine don't know if you have access to your attic and if you have a light up there with an outlet but that will be the best way to have a clean job for it, hope this will help a bit, also to your question, this unit comes with a 120v to 12 volt dc converter

How many speakers can you connect? I want to hook up about 5 speakers in my garage to play music over my iPhone.

You can connect as many speakers as to 100 watts is rated for, but you will want to wire them in a series/parallel combination to keep the impedance the same.See the following article to explainhttp://www.hometoys.com/content.php?url=/htinews/jun05/articles/nigelb/speakers.htm

Will this amp work with four 8-ohm 120 watt speakers?

I think it would work but It would really be pushing its limits. I used it to power 2 6.5" Polk Audio db651 speakers. It pushed them great, Although it would clip out if I got to loud. If you do go with 4 speakers I'd be carful with the level. It is a great product though, I've bought several.
