very powerful, clean, durable

none

i just got this amp and it kicks ass. produces a lot of power, i had two 10" audiobahn 300w rms each and i blew both of them with this amp. plus the sound is super clean. i also compared to the my cousins fosgate 400a4 amp and the z440 pounds the fosgate out easily.

everything very very nice looking amps

also like the z600.. EXACTLY the same size as the z600, so might be a little big for small cars..

This is an awesome amp for your speakers. I''ve been running this amp for about 5 months now and the amp stays cold. power is just amazing. I have premier components with alpine rears, both are being sent over 60 watts each. the sound is clear as can be! no distortions, or interference. also like to add that premier components are awesome for the price. good mid range bass and high end frequencies. been blasting my system for 5 months with my 2 hifonics amps and couldnt be any happier!
