My current design is to use a Phoenix Gold amp (600 watts x 4 channels, so it would put out about 300-350 watts per 12" sub if I bridge the front 2 and the rear 2 channels). The subs are rated at about 500 RMS each, so my fear is that pushing them with 350 watts per sub will not allow me to reach the full potential of the subs. The nice thing about my original design is that the sub and amp manufacturer are the same, and I hear that is always a good thing.
However, now I'm thinking that I might want a little more power, so I'm considering running the Soundstream Picasso PIC2.880. This amp will put out about 440 watts x 2 channels so it will push 440 watts per sub. Problem is that the amp itself isn't as high quality as the Phoenix Gold amps. If I went with the Soundstream RUBICON series, it would be, however right now, I'm thinking about the Picasso line.
My question then becomes.....does the amp have to be that high quality when it's running a sub? In other words, would I notice the difference between the Picasso series and the Rubicon series?
