Hifonics ZXi 4006...

I have this amp I have had no problems with this amp at all. Works great, does'nt get hot at all and I'm pushing two Diamonds 6 1/2's. On my doors at 100 watts each, this amp is great to have. The letters light up too, so it's cool at night to show off. For the price you pay for here, you get an awesome product. I have heard that Hifonics amps do'nt push what they say. Well, I tested my system once I put it together, this amp is doing it's job. With no problems, so if your thinking about putting a stereo system in your vehicle. Look at some of the Hifonic amps they have, I think they do just as good. As some of these higher priced amps out there. I was going to get us amps, but I found Hifonics do just as good. Saving money is one thing I look at too, so depending what you want to spend. Most of the time your just paying for the name anyway. Sonic electronics is the way to go if your putting a system in.
