Depends on the weight of the amp(s), how important decor is to you, and whether you're in a house or apartment/condo. I have several suggestions for you either way.... oh and if you are in a house one option to consider.
If you have your system on the main floor of your house you could always install the amps on the floor below, under your speakers. Drill a hole through the floor behind each speaker and you have a very elegant solution. This would make for a long interconnect BUT short speaker wires. Assuming there's no WAF issues on the floor below (and there IS a floor below) and you can install your amps any way you see fit, it's worth tackling.
