You can buy resilient channel at Home Depot. It's not as good as the other things we've been discussing but if you have an open stud garage without existing drywall and you are going to put some fresh drywall up, it is better than any of the alternatives.
Carpet on the wall hiding behind something else won't do anything. People are confused between the high frequency absorption they hear next to a piece of carpet and "sound proofing". What you are going to hear outside is mostly the boom of the kick drum. And if you pad the death of the inside that's all you're going to hear in there as well.
What you need is something compliant that will give at low frequencies so that the soundwaves can be damped out by something inbetween the inner and outer walls. This is behind the cheapo trick of leaning drywall against the existing walls. The inner wall is basically unsupported and flexible. So the noise inside makes it vibrate easily. That is re-radiated by the otherside of the sheet into hopefully a bunch of fiberglass insulation that damps the sound level before it hits the normal walls of the structure. That's why I advised that if you're dead set on carpet (cheap nylon carpet also being bad news for fire) that hanging it away from the wall would at least make for a compliant surface with some damping. Stapling insulation to the wall behind it would be much more effective and cheaper than another layer of carpet. Drywall is also cheaper than carpet so you'd actually be money ahead by getting some steel studs from Home Depot (I think they're about $5 each, cheaper and more effective at soundproofing than wood 2x4s because of their floppyness) and putting up an isolated interior wall.
Again, go to the Gearslutz studio building forum. I believe Ted contributes there, as do several other professionals in the field. And you can read all the stories about people who thought they could save money by doing this or that (including some of the things you are talking about) only to find out that it would have been cheaper and actually result in a usable room to follow the advice of people who have been there and know what they're talking about.
Those who do learn from history are doomed to repeat it.
