Might I suggest ATI? I am a custom installer, and have had great success installing them in situations such as yours. They make two five channel amps and one six channel amp. Each channel is rated to either 150 or 250 per channel. The amps can also be bridged for even higher output, although I can't see a sitation where this would be necessary. If you don;t have a local dealer let me know, because I can give you a really good price on there great amps. Some have likened them to a Krell amp at a real world price. Check out their website at www.ati-amp.com.
