Alpine PDX-4.150

Good – I've had mine about 18 months running a pair of splits and a sub. Very happy with it and do not even know it is there (visually). Provides the Focal splits and Image Dynamics 10" sub with enough clean power to keep me happy. If you need a small (dimension) amp and can afford it, just do it. Very compact - easy to fit under the seat. Reliable. Looks good (if you want to display it). Quite pricey for it's class.
