Crisp Clean Power

First time I had committed to a high end amplifier I was optimistic yet apprehensive. Happily the PDX-4M ROCKS. My jeep Cherokee has two 6.5in component speakers in the front and two 6.5in in the back doors. Both sets of speakers are alpine type -R. This small cool-running very powerful amp tests their limits. I highly recommend this amp.

Excellent Quality

I purchased this and a PDX 5 for my boat and could not have been more pleased. Alpine makes a rock solid product. I get endless positive comments on my marine sound system that is completely Alpine. Thanks for making it so easy.
