A lot. Re read what the person who started the post is looking for. On a side note CCA does perform better than OFC except in every test ever conducted. Please stop telling people what you think they should do. People don't come on here to have you tell them how ct sounds is awesome and hifonics rocks or what you would do. Most people are looking for legitimate answers to their issues. Don't try and spout efficiency is better on a 400-500 watt system, it's negligible at best. And yes a high end constant power amplifier, in most given cases, will out perform a "class d"
