I have this amp running 2 jl audio 6x9s (100 watts per speaker) and a polk audio db6501 component system (100 watts per speaker) this amp runs them great no distortion at all even when i turn all the levels all the way up not a single bit of distortion. Pros- high output, great looking, not expensive and doesn't get hot. Cons- large in size plastic mounting brackets. Overall i would recommend this amp to anyone looking at it.

I purchased this to power 4 sundown neopro's and if you know your stuff theyre no joke. it powers them well, my only complaint is that the mounting brackets are plastic and it makes it look very cheap. but the power is there.

Hooked this amp up to 4 kenwood performance series speakers for my doors and it works great! Doesn't heat up and hasn't blew out on me, so all in all I would say this was an awesome deal!

This amp has unbelievable power. I have a pair of 6x9 two way and a pair of two way 6.25 rockford fosgates in my tacoma and it turns heads big time. My friends think I am running subs. The design of this amp along with its built in crossover features makes it a must have. My next purchase will be the GLX 1000.1 and a single p3 DVC rockford fosgate 10.
