let me start by saying that 100watts is the minimum wattage they will let this amp pass with! each comes with a birth certificate and mine actually is 123RMS @ 4ohms :D

this thing is a power house, every clear, and dependable. i am running these with type r components and coaxials and they are perfect together. i can not turn up my radio past 24(out of 40) with out my ears starting to hurt.

my system consist of the following:
Pioneer AVH-P5200DVD head unit.
Memphis PR.1000.1 running
Alpine SPR-17C
Alpine SPR-17S
Alpine PDX-F4
2 Alpine SWR-1222D

I don't even know where to start. The RMS on my birth certificate is 123w per channel. I upgraded from an audiobahn 600w amplifier and the sound quality does not compare. The Alpine PDX F4 makes my Type S speakers sound amazing.

The only con I have with it is the price but I figured it would pay off in the long run since I can take it car to car.

Definitely more than satisfied with this purchase. I would recommend it to everyone.

What else to say but wow. This this is amazing. It is crazy how they can stuff all that technology into such a small package, but they sure did! It is so clear it is like hearing my music for the first time. I loved my Phoenix Gold Amps, but this is a whole 'nother beast. <3 Alpine!
