I thought we could use this thread so that people could post amps that they have benched and amps that they have birth sheets on and compare them to what the company claims the output will be. For example, I have heard that companies such as boss and sony don't do near their rated power. So has anyone ever benched a sony or boss? or have birth sheets on them? I am just curious to see if most companies' amps actually do their rated power. This would also be a helpful thread when people are looking for amps so that they can know how much power to expect from the amp depending on what company they buy from. So post away......there are plenty of amps out there....
