Great for the price
I have this amp running my door 6.5 component's and rear 6.5 component's and they get super loud! It gets a little warm but has never gotten hot, even after long road trips. Great amp for the price.

GREAT amp for the money
This is a great amp for the money...right now im having it push 4 polk audio db 5251 and they are screaming when i turn it up...although the amp does get a bit warm it never got hot...only problem that i had was that i couldnt fit my 4 gauge Knukonceptz Kolossus wires and had to trim it a bit but other than that great amp for the money.

amp review
I just installed it today. Have to install the
Radio and rca plugs on Friday. Then I will see how it plays. But it's a solid piece of equipment
I would recommend everyone to buy it. Auto Tech.has been out for years.

Absolutely amazing power, features, and quality for money!
Wow! Simply amazing! With this 4 channel, 2 ohm stable, bridgeable amp, you can run 4 channels at 200 watts RMS at 2 ohms. So you can run four 2 ohm subs, or two 4 ohm dvc subs at 200 + 200 x 2, or sub(s) on 2 channels, and your mids and highs on the other 2 channels at 200 watts RMS x 2 for the sub(s), and 200 watts RMS x 2 for the mids and highs, with low, and high pass crossovers for each respectively in your car with just a $25 4 gauge wiring kit. It's a real 750-800 watt RMS watt amplifier, with a 9 db bass boost, twin adj. high and low pass crossovers, two 30 amp fuses, which is more than the 2000 watt max Autotek amplifier has. You can't make more power than the fuse protection will allow. So I feel they were honest about it's RMS power, which is the only numbers you should be concerned about when purchasing an amplifier. I tested it and the numbers were very close to it's advertised RMS power. Even though it says 1500 watts max, everyone should know that most amp companies will double the RMS output for their advertised max output. At least it really made at least if not more than it's advertised RMS power, a lot of less expensive amps don't even do that. So for an honest 750-800 watts, that can be used in so many different configurations, and being a very nice looking, great quality amp, for $67.50 for each of the 2 I bought, with free shipping, was an absolutely incredible deal. 2 bridged 4 ohm channels makes a rediculous amount of power for $67! I couldn't be happier about the purchase! It's too much power for the two 300 watt RMS 12" subs I have now that I thought would be able to handle the power from past experience with the subs. So it looks like I'll be buying 2 more of the same subs, or just 2 louder, better subs, that have higher power handling capabilities, which should be about the same amount of bass if not more than the 4 lower priced subs. Either way you can't go wrong with this amp. Even at $75, without the extra 10% off I got during the Grads sale (thank you Sonic Electronix) it's still an amazing deal. I have one running in my home off of a $14 ebay Dell server power supply off of a 110V oulet getting 67.5 amps at 12 volts. It works amazing powering 4 quality 12" subs, two car audio subs, and 2 low frequency, long throw home audio subs, and can run all day long like that if I wanted to. It's way overkill for a home audio surround, but too much is just right! A true 800 watts for $80 total in my home audio setup is sick! Thanks again Sonic Electronix!

Great Value
Got 2 of these amps 1 for my front/rear speakers & 1 for my sub, the both run great and sound great. Was a bit worried buying these because the price was so low, but they are great power house amps.
