Hey folks!
So I'm looking at the Alpine PDX 4.150 amp. It seems to have lots of juice, it's very efficient, it's very small and easy to install and seems to be perfect for my application. However, it's a class D (digital switching) amp and I'm not sure what the low-down on these type of amps is. I know they were used for subs for some time now, but are they now at the point where they're acceptable for full range speakers? On paper the PDX line has a THD of 1%, is that something to be concerned with? The salesmen tell me that it's a great amp and that I shouldn't worry about the THD.
As for my setup, I plan to run the fronts of the amp and to either 1) bridge the two remaining channels for sub or 2) just run the rears off the amp as well. Keep in mind that option is not a long term consideration, but I may do it while I'm shopping around & saving up for a sub.
Any thoughts?
