This is a great amp I have had it for two years and it makes my subs beat harder than bigger amps I had before. It has never went into protection mode and I have cranked it the other guy must got some thing wrong trust me great amp

I purchased this amp in decmber of 2009. I installed it in my single cab fullsize truck. I connected it to 2 JL Audio 12W1v2-4 subwoofers I also purchased from here. It made my whole truck shake. The clarity, power, and preformance was amazing. It never got hot or went into protection mode and held continuous low tones at loud volumes with ease. About 2.5 years after I got the amp, the bass/gain remote quit working but it still preforms just fine. I never sent it back to have it fixed because it wasnt that big of a deal to me at its age. I now have it connected to 2 kenwood 12" KFC-W3012 in my wifes car and the amp just out preforms any other I have owned. I have recently purchased another kicker amp and i am waiting for it to be shipped. This amp is still working like new exept for the bass/gain controle and its over 3 years old. I would recommend this amplifier to anyone whos looking for Quality, Durability, and Power for Everyday use.

I have 2 of these amps. One for my 06 expedition punching 2 JL w3's and one for my girlfriends pushing 1 diamond audio D3. I am very impressed with the performance of these amps. The one in my truck get hot, but never turns off. I also have the bass knobs on both amps. Overall very good amp.

You can never go wrong with Kicker products. I was suggested by a Sonic Electronix employee to buy this to power my 600W RMS Alpine type R. At first, I was a bit skeptical, seeing as though the wattage is only 500W RMS. I decided I'd give it a shot and I'm glad I did! It pushes my Type R all day long! absolutely love it, great amp!

I have this amp hooked up to an Alpine type r 15 and it slams. I will soon be upgrading to the zx750.1 to give my sub its full potential but this thing gets the job done well.

This a great amp for any system that is limited on space. The small footprint allows the flexibility to install in various locations. Besides the fact that I have always been a kicker fan this amp is under rated or should I say accurately rated for continuous power. I would recommend this amp.

Installed this amp for a friend paired with two 12" Rockford P2's and boy did this amp makes those puppies slam! Birth sheet said 571 rms at 2-ohms, what a deal! Kicker FTW!

This amplifier is amazing. I got this Kicker ZX500.1 and 2 Kenwood 10" 's and all I can say is my Chevy Silverado 1999 15000 is BUMPINNN Now. Very pleased. Customer/Techincal Support from Sonic Electronix helped me come about this choice and I am very pleased! Thanks Steve!

For this 500 watt rms amp this little thing is mean and it will push every bit of 500 watt rms like nothing. I put a meter on it and mine was putting out 550 watt rms a little more than its rated at.

Great amp at great price. Solid amp that actually puts out the power it is rated at.

This amp kicks **s! I just installed two of these in two different vehicles, both using Kicker CVR 12's in Kicker ported boxes and they hit hard! Great amp for an excellent price!

Bought this amp to push an old Kicker L5 solo baric 12". It definately does the trick, being a single channel amp on the one sub. Would highly recommend this for overall good quality sound and cost. Been using Kicker products for years and have always loved them.

Ok this amp pounds. And I mean POUNDS. I have it powering two kicker CVR12's and they make my '07 4runner shake and my passengers want to sit in the back seat just for the back massage. i am buying a second one so i can fully power both of my subs (one for each) and i would reccommend this to anyone. I've had it for about 5 months now and i love it.

Fantastic. This amp is so great, and what a deal! Great quality, 2 year warranty. My Earthquake 12dbxiD sounds like nothing I have ever heard. Thanks Andrew in Tech Support for this recommendation. Says 500 W the certificate that came with this specific amp say 590. I am not complaining.

This amp makes my 2 15 inch kicker comps blow up my trunk. Excellent quality amp thanks Sonic for the great shipping and awesome customer service!!!! Milwaukee Luvs Sonic!!

I bought this amp to replace my old pioneer. What a world of difference. The lows that this amp pushes to my 15 inch comps is incredible. Pioneer has always made good stuff but this kicker put it to shame. Very happy with this amp, prolly gonna stick to kicker for amps.
