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 is one of Hifonics best 4-channel amps power is very clean and strong i have it on Alpine Type-R 6/9 and 5 1/4 components by Alpine I have a Kicker crossover so I did not use the amps the amps gain is turned up a little over half way and I can barely stay in the car had a mb quart that I think was defective and sent that back to sonic and purchased this one I have no complaints what so ever the amp reminds me of some of hifonics old stuff it would be a wise decision for anyone to purchase this amp I have been into car audio for over 20 years and with this amp you are getting your moneys worth great amp dont no how long it will last but I think it is a very wwell designed amp will post a new review if anything changes .

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.

This truly brings my system alive... I hear every detail through my interior speakers!!!

Have this powering four interior car speakers with 100 watt rms each. Sound is so crisp and clean. Love it.
